Objective Respiratory syncytial virus (RSV) is the most common viral respiratory infection in infants. This study aimed to establish the potential changes in the clinical course of RSV in the neonatal period with the onset of the coronavirus disease 2019(COVID-19) pandemic. Study Design During the observational study period, newborns diagnosed with community-acquired RSV infection and admitted to the neonatal intensive care unit (NICU) were evaluated. RSV-infected neonates before the COVID-19 pandemic were classified as Group 1 , those during the strict isolation period as Group 2 , and RSV-infected newborns after the removal of restrictions were classified as Group 3. Results A total of 208 community-acquired RSV-infected neonates were analyzed. The median age at admission to the NICU was 26 days, and the mean gestational week was 37.2 ± 2.7. The ratio of hospitalized babies with RSV infection to all hospitalized newborns rose after the pandemic significantly (1.9, 1.6, and 5.2%; p < 0.001). Following the pandemic, there was an increase in full-term, early-term, and late-preterm cases. Nevertheless, no change was observed in the number of preterm cases (p > 0.05). There was also a statistically significant increase in the need for intubation, noninvasive ventilation (NIV), supplemental oxygen, inhaled bronchodilator drugs, and length of hospital stay in Group 3 after the pandemic (p < 0.001). All these parameters related to more severe RSV infection when the precautions were removed, while there was a milder disease with restrictions during the pandemic in Group 2 (p < 0.001). However, none died due to RSV infection during the study because of timely supportive care. Conclusion Following the COVID-19 pandemic, the frequency and severity of RSV infection in newborns have increased, and it can result in a serious clinical picture even in full-term babies with no comorbidities. Attention to strict contact precautions, particularly in newborns, who are a more vulnerable population after the pandemic, may play an important role in any future outbreak. Key Points The course of neonatal RSV infection has changed after the pandemic. A statistically significant increase was observed in the need of intubation in newborns with RSV. The strict precautions during the pandemic also helped to prevent the transmission of RSV. [ABSTRACT FROM AUTHOR]

Introduction: Although largely used, the place of oxygen therapy and its devices in patients with acute hypoxemic respiratory failure (ARF) deserves to be clarified. The French Intensive Care Society (Société de Réanimation de Langue Française, SRLF) and the French Emergency Medicine Society (Société Française de Médecine d'Urgence, SFMU) organized a consensus conference on oxygen therapy in ARF (excluding acute cardiogenic pulmonary oedema and hypercapnic exacerbation of chronic obstructive diseases) in December 2023. Methods: A committee without any conflict of interest (CoI) with the subject defined 7 generic questions and drew up a list of sub questions according to the population, intervention, comparison and outcomes (PICO) model. An independent work group reviewed the literature using predefined keywords. The quality of the data was assessed using the GRADE methodology. Fifteen experts in the field from both societies proposed their own answers in a public session and answered questions from the jury (a panel of 16 critical-care and emergency medicine physicians, nurses and physiotherapists without any CoI) and the public. The jury then met alone for 48 h to write its recommendations. Results: The jury provided 22 statements answering 11 questions: in patients with ARF (1) What are the criteria for initiating oxygen therapy? (2) What are the targets of oxygen saturation? (3) What is the role of blood gas analysis? (4) When should an arterial catheter be inserted? (5) Should standard oxygen therapy, high-flow nasal cannula oxygen therapy (HFNC) or continuous positive airway pressure (CPAP) be preferred? (6) What are the indications for non-invasive ventilation (NIV)? (7) What are the indications for invasive mechanical ventilation? (8) Should awake prone position be used? (9) What is the role of physiotherapy? (10) Which criteria necessarily lead to ICU admission? (11) Which oxygenation device should be preferred for patients for whom a do-not-intubate decision has been made? Conclusion: These recommendations should optimize the use of oxygen during ARF.

IntroductionMethodsResultsDiscussionOne-lung ventilation (OLV) is a prevalently used technique to sustain intraoperative pulmonary function. Resolvin E1 (RvE1), a specialized pro-resolving lipid mediator, accelerates the resolution of inflammation in the lungs. However, its therapeutic effects on OLV-induced lung injury remain unclear.We initially developed an OLV rat model and treated it with RvE1. Subsequently, we assessed the wet/dry ratio of the lung tissue, performed hematoxylin and eosin staining, and calculated the ratio of polymorphonuclear cells to white blood cells in the bronchoalveolar lavage fluid. Additionally, we assessed apoptosis, inflammatory factor levels, and lung permeability in the rat lung tissues in the RvE1 treated and untreated groups and explored the molecular mechanisms mediated by RvE1.Our results indicated that RvE1 alleviated lung injury and inflammation and improved lung tissue apoptosis and permeability in OLV rats. Moreover, RvE1 suppressed the expression of the BLT1/2 signaling pathway and its ligands. The use of BLT2 and BLT1 inhibitors (LY255283 and U-75302, respectively) enhanced RvE1’s anti-inflammatory effects and reduced lung injury. Furthermore, synergistic treatment with the BLT2 inhibitor and RvE1 provided grater benefits by more effectively inhibiting the NF-kB, p38 MAPK, and ERK pathways.RvE1 and the inhibition of BLT2 signalling reduce the inflammatory response and mitigate OLV-induced lung injury. These findings suggest a novel therapeutic pathway for managing OLV-related complications. [ABSTRACT FROM AUTHOR]

Background: For patients with sepsis receiving non-invasive ventilation (NIV), early rehabilitation is crucial. The Sitting Baduanjin (SBE) is an efficient early rehabilitation exercise suitable for bed patients. There is no consensus about the effect of SBE on the early rehabilitation of septic patients with NIV. This study focused on how the SBE affected the early rehabilitation of sepsis patients with NIV. Methods: 96 sepsis patients with NIV were randomly assigned to either an Baduanjin group that received the SBE based on the routine rehabilitation exercise (n = 48) or a control group (n = 48) that received routine rehabilitation exercise. The primary outcome was the Medical Research Council(MRC)score, and the Barthel Index score, the duration of NIV, length of ICU stay, length of total stay, hospitalization expense as secondary outcomes. Results: A total of 245 sepsis patients were screened, with 96 randomly assigned. The study was completed by 90 patients out of the 96 participants.Results revealed that the MRC score increased in both groups, but the improvement of muscle strength in Baduanjin group was more obvious, with statistical significance (p < 0.001).There was statistically significantly difference between the two groups in Barthel Index at the day of transfer out of ICU(P = 0.028).The patients in the Baduanjin group had an average reduction of 24.09 h in the duration of NIV and 3.35 days in total length of hospital stay compared with the control group (p < 0.05).Of note, the Baduanjin group had significantly reduction the total hospitalization expense. No serious adverse events occurred during the intervention period. Conclusions: In patients with sepsis, the SBE appears to improve muscle strength and activities of daily living (ADL), and lowed the duration of NIV, the length of the total stay, and the hospitalization expense. Trial registration: The study registered on the Chinese Clinical Trial Registry (www.chictr.org.cn), Clinical Trials identifier ChiCTR1800015011 (28/02/2018). [ABSTRACT FROM AUTHOR]

Introduction Despite the significant need for mechanical ventilation in- and out-of-hospital, mechanical ventilators remain inaccessible in many instances because of cost or size constraints. Mechanical ventilation is especially critical in trauma scenarios, but the impractical size and weight of standard mechanical ventilators restrict first responders from carrying them in medical aid bags, leading to reliance on imprecise manual bag-mask ventilation. This is particularly important in combat-related injury, where airway compromise and respiratory failure are leading causes of preventable death, but medics are left without necessary mechanical ventilation. To address the serious gaps in mechanical ventilation accessibility, we are developing an Autonomous, Modular, and Portable Ventilation platform (AMP-Vent) suitable for austere environments, prolonged critical care, surgical applications, mass casualty incidents, and stockpiling. The core system is remarkably compact, weighing <2.3 kg, and can fit inside a shoebox (23.4 cm × 17.8 cm × 10.7 cm). Notably, this device is 65% lighter than standard transport ventilators and astoundingly 96% lighter than typical intensive care unit ventilators. Beyond its exceptional portability, AMP-Vent can be manufactured at less than one-tenth the cost of conventional ventilators. Despite its reduced size and cost, the system's functionality is uncompromised. The core system is equipped with closed-loop sensors and advanced modes of ventilation (pressure-control, volume-control, and synchronized intermittent mandatory ventilation), enabling quality care in a portable form factor. The current prototype has undergone preliminary preclinical testing and optimization through trials using a breathing simulator (ASL 5000) and in a large animal model (swine). This report aims to introduce a novel ventilation system and substantiate its promising performance through evidence gathered from preclinical studies. Materials and Methods Lung simulator testing was performed using the ASL 5000, in accordance with table 201.105 "pressure-control inflation-type testing" from ISO 80601-2-12:2020. Following simulations, AMP-Vent was tested in healthy 10-kg female domestic piglets. The Children's Hospital of Philadelphia Institutional Animal Care and Use Committee approved all animal procedures. Swine received 4-min blocks of alternating ventilation, where AMP-Vent and a conventional anesthesia ventilator (GE AISYS CS2) were used to titrate to varied end-tidal carbon dioxide (EtCO2) goals with the initial ventilator switching for each ascending target (35, 40, 45, 50, 55 mmHg). Results During ASL 5000 simulations, AMP-Vent exhibited consistent performance under varied conditions, maintaining a coefficient of variation of 2% or less within each test. In a large animal study, AMP-Vent maintained EtCO2 and SpO2 targets with comparable performance to a conventional anesthesia ventilator (GE AISYS CS2). Furthermore, the comparison of minute ventilation (V e) distributions between the conventional anesthesia ventilator and AMP-Vent at several EtCO2 goals (35, 40, 45, 50, and 55 mmHg) revealed no statistically significant differences (p = 0.46 using the Kruskal–Wallis rank sum test). Conclusions Preclinical results from this study highlight AMP-Vent's core functionality and consistent performance across varied scenarios. AMP-Vent sets a benchmark for portability with its remarkably compact design, positioning it to revolutionize trauma care in previously inaccessible medical scenarios. [ABSTRACT FROM AUTHOR]

BACKGROUND AND OBJECTIVES: Children with new tracheostomy and invasive mechanical ventilation (IMV) require transitional care involving caregiver education and nursing support. To better understand hospital resource use during this transition, our study aimed to: (1) define and characterize low-resource days (LRDs) for this population and (2) identify factors associated with LRD occurrence. METHODS: This retrospective cohort analysis included children ≤21 years with new tracheostomy and IMV dependence admitted to an ICU from 2017 to 2022 using the Pediatric Health Information System database. A LRD was defined as a post tracheostomy day that accrued nonroom charges <10% of each patient's accrued nonroom charges on postoperative day 1. Factors associated with LRDs were analyzed using negative binomial regression. RESULTS: Among 4048 children, median post tracheostomy stay was 69 days (interquartile range 34-127.5). LRDs were common: 38.6% and 16.4% experienced ≥1 and ≥7 LRDs, respectively. Younger age at tracheostomy (0-7 days rate ratio [RR] 2.42 [1.67-3.51]; 8-28 days RR 1.8 (1.2-2.69) versus 29-365 days; Asian race (RR 1.5 [1.04-2.16]); early tracheostomy (0-7 days RR 1.56 [1.2-2.04]), and longer post tracheostomy hospitalizations (31-60 days RR 1.85 [1.44-2.36]; 61-90 days RR 2.14 [1.58-2.91]; >90 days RR 2.21 [1.71-2.86]) were associated with more LRDs. CONCLUSIONS: Approximately 1 in 6 children experienced ≥7 LRDs. Younger age, early tracheostomy, Asian race, and longer hospital stays were associated with increased risk of LRDs. Understanding the postacute phase, including bed utilization, serves as an archetype to explore care models for children with IMV dependence. [ABSTRACT FROM AUTHOR]

A 7-week-old infant presented to the emergency department with fussiness, abstract decreased oral intake, loose stool, and respiratory distress for 2 days. The patient was born full-term with an uncomplicated birth history but had a history of slow weight gain. He was alert, but toxic-appearing at presentation, hypothermic with signs of dehydration, and with respiratory failure. He was found to have severe anion gap metabolic acidosis, hypokalemia, elevated lactate, and hyperammonemia. He responded well to initial resuscitation and was admitted to the ICU for intravenous electrolyte replacement, bowel rest, and respiratory support. A workup was pursued for failure to thrive with severe malnutrition, hyperammonemia, hyperlactatemia, anemia, vitamin D deficiency, and electrolyte abnormalities. After stabilization, he was restarted on enteral feeds and had a recurrence of loose stool and severe electrolyte abnormalities, which were refractory to enteral supplementations and required readmission to the ICU. His hospital course extended several weeks, included several subspecialty consultations, and ended with a surprising diagnosis of exclusion based on his clinical response to therapy.

Introduction: This article aims to characterise hospital admissions involving opioid toxicity across South Australia to guide future implementation and evaluation of risk mitigation strategies. Methods: International Classification of Diseases, 10th Edition codes (T40.0–T40.4) were used to identify admissions involving pre‐hospital opioid toxicity in public hospitals across South Australia from 1 June 2017 to 30 August 2020. Demographic and episode of care data were extracted and summarised using descriptive statistics. Admission cost estimates were calculated using Independent Hospital Pricing Authority data. Results: A total of 2046 cases met the criteria for inclusion; over half (56%) were female and median age on admission was 44 years (interquartile range 27 years). Where opioid toxicity was the primary diagnosis, 70% of admissions did not specify the responsible opioid and 23% were related to heroin use. One‐fifth of admissions occurred outside of metropolitan Adelaide. Individuals living in an area of relative socio‐economic disadvantage were over‐represented. Over half of admissions required a stay >24 h; 19% were admitted for ≥5 days, 22% required intensive care and ~10% required mechanical ventilation. The total estimated cost of admissions involving opioid toxicity in South Australia over the 3‐year period was $18,230,546.50, equating to $5.6 million per annum. Discussions and Conclusions: These findings highlight the significant personal, fiscal, and systemic impacts of opioid toxicity‐related hospital admissions in South Australia and provide a baseline to evaluate the effectiveness of initiatives to reduce opioid‐related harm, including real‐time prescription monitoring and take‐home naloxone supply.

Purpose: Approximately 30%of people infected with COVID-19 require hospitalization, and 20% of them are admitted to an intensive care unit (ICU). Most of these patients experience symptoms of fatigue weeks post-ICU, so understanding the factors associated with fatigue in this population is crucial. Methods: Fifty-nine patients (38-78 yr) hospitalized in ICU for COVID-19 infection for 32 (6-80) d, including 23 (3-57) d of mechanical ventilation, visited the laboratory on two separate occasions. The first visit occurred 52 ± 15 d after discharge and was dedicated to questionnaires, blood sampling, and cardiopulmonary exercise testing, whereas measurements of the knee extensors neuromuscular function and performance fatigability were performed in the second visit 7 ± 2 d later. Results: Using the FACIT-F questionnaire, 56% of patients were classified as fatigued. Fatigued patients had worse lung function score than non-fatigued (i.e., 2.9 ± 0.8 L vs 3.6 ± 0.8 L; 2.4 ± 0.7 L vs 3.0 ± 0.7 L for forced vital capacity and forced expiratory volume in 1 s, respectively), and forced vital capacity was identified as a predictor of being fatigued. Maximal voluntary activation was lower in fatigued patients than non-fatigued patients (82% ± 14% vs 91% ± 3%) and was the only neuromuscular variable that discriminated between fatigued and non-fatigued patients. Patient-reported outcomes also showed differences between fatigued and non-fatigued patients for sleep, physical activity, depression, and quality of life (P < 0.05). Conclusions: COVID-19 survivors showed altered respiratory function 4 to 8 wk after discharge, which was further deteriorated in fatigued patients. Fatigue was also associated with lower voluntary activation and patient-reported impairments (i.e., sleep satisfaction, quality of life, or depressive state). The present study reinforces the importance of exercise intervention and rehabilitation to counteract cardiorespiratory and neuromuscular impairments of COVID-19 patients admitted in ICU, especially individuals experiencing fatigue.

Salicylate poisoning may lead to critical acid–base disturbances. Tracheal intubation and mechanical ventilation for patients with severe salicylism has been strongly discouraged. This study aims to describe pH trends, complications, and outcomes in a cohort of salicylate-poisoned patients who were intubated. This retrospective observational study included adults presenting to the emergency department (ED) with severe salicylate poisoning (serum salicylate concentration >40 mg/dL and admission to an intensive care unit) over a 14-year period (2007–2021). The primary and secondary outcomes were the change in serum pH and the occurrence of severe complications (systolic blood pressure <80 mm Hg, oxygen saturation <80%, or cardiac arrest), respectively, in the 6 h after presentation. Among 32 adults with severe salicylate poisoning (median serum salicylate level 64.2, interquartile range 52.5–70.7), 11 (34%) underwent tracheal intubation. The initial mean pH (±SD) in the no intubation group was 7.48 ± 0.07 and was 7.36 ± 0.04 in the intubation group. The mean absolute difference in pH measured before and after intubation was -0.02 (95% confidence interval −0.11 to 0.07). No severe complications were observed during or up to 6 h after tracheal intubation and mechanical ventilation. In our single-center experience managing adults with severe salicylate poisoning, tracheal intubation and mechanical ventilation were not associated with substantial perturbation of serum pH or severe complications. These findings challenge the current paradigm that these interventions should be avoided in salicylate-poisoned patients. [ABSTRACT FROM AUTHOR]

Background: Many patients critically ill with COVID-19 develop acute respiratory distress syndrome (ARDS) necessitating mechanical ventilation and proning. Although proning is lifesaving, it has been linked to the occurrence of facial pressure injuries (PIs). Objectives: To evaluate the incidence and use of prevention strategies and identify predictors of facial PIs in patients who received ventilator and proning treatments in COVID-designated intensive care units at 2 large quaternary medical centers in the Midwest. Method: This was a retrospective cohort study using data extracted from an electronic health record between October 2020 and February 2022. Demographics, clinical and care variables, and PI outcomes were analyzed to identify predictors of PI using logistic and Cox regression. Results: The cohort (N = 150) included patients from 2 units, unit a (n = 97) and unit b (n = 53) with a mean age of 60 years, with 68% identifying as male. Patients were vented for an average of 18 (SD, 16.2) days and proned for an average of 3 (SD, 2.5) days. Many (71%) died. Over half (56%) developed facial PI with a proning-exposure-adjusted incidence rate of 18.5%. Patients with PI were significantly different in several factors. Logistic regression showed predictors of PIs were duration of mechanical ventilation (in days; P = .02) and head turned (P = .01). Cox regression also identified head turn as predictive (P < .01), with Black/African American race as protective (P = .03) Discussion: Critically ill patients with COVID-19 receiving ventilator and proning therapy developed facial PIs despite the use of recommended prevention practices. Further research on effective PI prevention strategies is needed. [ABSTRACT FROM AUTHOR]

Purpose: To identify pathogenic microorganisms and microbiological risk factors causing high morbidity and mortality in immunocompromised patients requiring invasive mechanical ventilation due to pneumonia. Methods: A retrospective single-center study was performed at the intensive care unit (ICU) of the Department of Internal Medicine at Heidelberg University Hospital (Germany) including 246 consecutive patients with hematological malignancies requiring invasive mechanical ventilation due to pneumonia from 08/2004 to 07/2016. Microbiological and radiological data were collected and statistically analyzed for risk factors for ICU and 1-year mortality. Results: ICU and 1-year mortality were 63.0% (155/246) and 81.0% (196/242), respectively. Pneumonia causing pathogens were identified in 143 (58.1%) patients, multimicrobial infections were present in 51 (20.7%) patients. Fungal, bacterial and viral pathogens were detected in 89 (36.2%), 55 (22.4%) and 41 (16.7%) patients, respectively. Human herpesviruses were concomitantly reactivated in 85 (34.6%) patients. As significant microbiological risk factors for ICU mortality probable invasive Aspergillus disease with positive serum-Galactomannan (odds ratio 3.1 (1.2-8.0), p = 0.021,) and pulmonary Cytomegalovirus reactivation at intubation (odds ratio 5.3 (1.1–26.8), p = 0.043,) were identified. 1-year mortality was not significantly associated with type of infection. Of interest, 19 patients had infections with various respiratory viruses and Aspergillus spp. superinfections and experienced high ICU and 1-year mortality of 78.9% (15/19) and 89.5% (17/19), respectively. Conclusions: Patients with hematological malignancies requiring invasive mechanical ventilation due to pneumonia showed high ICU and 1-year mortality. Pulmonary Aspergillosis and pulmonary reactivation of Cytomegalovirus at intubation were significantly associated with negative outcome. [ABSTRACT FROM AUTHOR]

Background: Multicenter early diuretic response (DR) analysis of single furosemide dosing following neonatal cardiac surgery is lacking to inform whether early DR predicts adverse clinical outcomes. Methods: We performed a retrospective cohort study utilizing data from the NEPHRON registry. Random forest machine learning generated receiver operating characteristic-area under the curve (ROC-AUC) and odds ratios for mechanical ventilation (MV) and respiratory support (RS). Prolonged MV and RS were defined using ≥ 90th percentile of observed/expected ratios. Secondary outcomes were prolonged CICU and hospital length of stay (LOS) and kidney failure (stage III acute kidney injury (AKI), peritoneal dialysis, and/or continuous kidney replacement therapy on postoperative day three) assessed using covariate-adjusted ROC-AUC curves. Results: A total of 782 children were included. Cumulative urine output (UOP) metrics were lower in prolonged MV and RS patients, but DR poorly predicted prolonged MV (highest AUC 0.611, OR 0.98, sensitivity 0.67, specificity 0.53, p = 0.006, 95% OR CI 0.96–0.99 for cumulative 6-h UOP) and RS (highest AUC 0.674, OR 0.94, sensitivity 0.75, specificity 0.54, p < 0.001, 95% CI 0.91–0.97 UOP between 3 and 6 h). Secondary outcome results were similar. DR had fair discrimination for kidney failure (AUC 0.703, OR 0.94, sensitivity 0.63, specificity 0.71, 95% OR CI 0.91–0.98, p < 0.001, cumulative 6-h UOP). Conclusions: Early DR poorly discriminated patients with prolonged MV, RS, and LOS in this cohort, though it may identify severe postoperative AKI phenotype. Future work is warranted to determine if early DR or late postoperative DR later, in combination with other AKI metrics, may identify a higher-risk phenotype. [ABSTRACT FROM AUTHOR]

Sudden unexpected postnatal collapse (SUPC) is a sudden collapse of the clinical conditions of a full-term or near-term newborn, within the first 7 days of life, that requires resuscitation with positive ventilation and who either dies, has hypoxic-ischemic encephalopathy, or requires intensive care. The incidence of SUPC is very low, and most often presents a negative prognosis. The BUB1B gene is a mitotic checkpoint of serine/threonine kinase B that encodes a protein crucial for maintaining the correct number of chromosomes during cell division. Mutations in the BUB1B gene are linked to mosaic variegated aneuploidy syndrome 1 (MVA1), a rare autosomal recessive disorder characterized by diffuse mosaic aneuploidies involving several chromosomes and tissues. This paper discusses a case of a newborn who had a spontaneous delivery. After 2 h and 10 min, the infant showed generalized hypotonia and cyanosis, and his doctors performed orotracheal intubation, cardiac massage, pharmacological hemodynamic therapy, mechanical ventilation, antibiotic therapy, and hypothermic treatment. The newborn was discharged after 5 months with the diagnosis of hypoxic-ischemic encephalopathy. Suspecting an SUPC, a complete genetic analysis was performed demonstrating a compound heterozygous mutations in the BUB1B gene. The newborn died at 6 months of life, 1 month after discharge. A complete autopsy was performed, determining that the cause of death was due to sepsis starting from a brocopneumonic process, with outcomes of hypoxic-ischemic encephalopathy (HIE). In this scenario, it is not possible to demonstrate the causal effect of this mutation, considering that it could play a causal or concausal role in the onset of SUPC. Further research based on multicenter studies, as well as on animal models, could be very useful to clarify the pathological effect of this mutation. [ABSTRACT FROM AUTHOR]

LENGTH of stay in hospitals , *NEONATAL surgery , *SURGICAL complications , *ARTIFICIAL respiration , *TREATMENT effectiveness , *NEWBORN infants - Abstract
Inappropriate perioperative fluid load can lead to postoperative complications and death. This retrospective study was designed to investigate the association between intraoperative fluid load and outcomes in neonates undergoing non-cardiac surgery. From April 2020 to September 2022, 940 neonates who underwent non-cardiac surgery were retrospectively enrolled and their perioperative data were harvested for further analysis. According to recorded intraoperative fluid volumes defined as ml.kg−1 h−1, patients were mandatorily divided into quintile with fluid load as restrictive (quintile 1, Q1), moderately restrictive (Q2), moderate (Q3), moderately liberal (Q4), and liberal (Q5). The primary outcomes were defined as prolonged length of hospital stay (LOS) (postoperative LOS ≥ 14 days), complications beyond prolonged LOS, and 30-day mortality. Secondary outcomes included postoperative complications within 14 days of hospital stay. The intraoperative fluid load was in Q1 of 6.5 (5.3–7.3) (median and IQR); Q2: 9.2 (8.7–9.9); Q3: 12.2 (11.4–13.2); Q4: 16.5 (15.4–18.0); and Q5: 26.5 (22.3–32.2) ml.kg−1 h−1. The odd of prolonged LOS was positively correlated with an increase fluid volume (Q5 quintile: OR 2.602 [95% CI 1.444–4.690], P = 0.001), as well as complications beyond prolonged LOS (Q5: OR 3.322 [95% CI 1.656–6.275], P = 0.001). The overall 30-day mortality rate was increased with high intraoperative fluid load but did not reach to a statistical significance after adjusted with confounders. Furthermore, the highest quintile of fluid load (26.5 ml.kg−1 h−1, IQR [22.3–32.2]) (Q5 quintile) was significantly associated with longer postoperative mechanical ventilation time compared with Q1 (Q5: OR 2.212 [95% CI 1.101–4.445], P = 0.026). Conclusion: Restrictive intraoperative fluid load had overall better outcomes, whilst high fluid load was significantly associated with prolonged LOS and complications after non-cardiac surgery in neonates. Trial registration: Chictr.org.cn Identifier: ChiCTR2200066823 (December 19, 2022). What is Known: • Inappropriate perioperative fluid load can lead to postoperative complications and even death. What is New: • High perioperative fluid load was significantly associated with an increased length of stay after non-cardiac surgery in neonates, whilst low fluid load was consistently related to better postoperative outcomes.

Objective: This study aimed to assess the effects of sodium-glucose co-transporter inhibitors (SGLT2i), glucagon-like peptide-1 receptor agonists (GLP-1RA), and dipeptidyl peptidase-4 inhibitors (DPP4i) on individuals subjected to diabetes and COVID-19. Methods: PubMed, Embase, Web of Science, and Cochrane Library were systematically searched to cover studies (except for case reports and review studies) published until August 30, 2022. The primary outcome was the mortality of people with diabetes and COVID-19. The secondary outcomes comprised the requiring intensive care unit (ICU) admission and mechanical ventilation. Two reviewers independently screened studies, abstracted data, and assessed risk-of-bias. Furthermore, the network meta-analyses (NMA) were conducted. Results: A total of 12 trials were involved in the analysis. The OR and 95% CI of mortality for SGLT2i compared with SGLT2i + GLP-1RA and DPP4i reached 0.41 (0.17,0.97) and 0.69 (0.49,0.98), respectively. The OR and 95% CI of requiring mechanical ventilation for SGLT2i compared with the DPP4i reached 0.85 (0.75,0.97). Conclusions: As revealed by the result of this study, SGLT2i is associated with the lower mortality rate in people with diabetes and COVID-19 among novel glucose-lowering drugs. And SGLT2i is linked to lower requiring mechanical ventilation. These findings can have a large impact on clinicians' decisions amid the COVID-19 pandemic. [ABSTRACT FROM AUTHOR]

Background: Physical restraint of patients in intensive care units (ICUs) has an estimated prevalence of 50%. Many medical centres do not have specific protocols for physical restraint, and the decision of whether to physically restrain a patient is up to the nursing staff. Disadvantages of physical restraint include injuries, exacerbation of agitation and an increased risk of developing post‐traumatic stress disorder (PTSD). Aim: To report prevalence and outcomes in terms of morbidity and mortality of physical restraint in general ICU patients in an 800‐bed secondary medical centre. Study Design: This retrospective study included 647 patients admitted to a general ICU in an 800‐bed secondary medical centre in Kfar Saba, Israel, between January and December 2020. Data included demographics, medical history, length of stay, need for mechanical ventilation, number of ventilation days, 28‐day mortality, reason for admission, agitation rate assessed by Richmond Agitation and Sedation Scale (RASS) score, need for physical restraint and need for anti‐psychotics. Results: Among the patients, 40% (256 of 647) required physical restraint. Older adult patients had a greater likelihood of being physically restrained along with those admitted because of sepsis or acute respiratory failure. Among the study sample, 11% (71 of 647) required anti‐psychotics. Patients who were restrained had longer duration of ventilation (5.9 ± 8.2 vs. 0.36 ± 1.4 days; p <.001) and higher 28‐day mortality (0.26 ± 0.45 vs. 0.07 ± 0.25, Z = 6.86, p <.001). There was no difference in medical history, except for chronic drug abuse, which was more frequent in the restraint group (18 [6.9%] vs. 11 [2.8%], respectively; p =.019), as well as the use of anti‐psychotic medications (24 [9.3%] vs. 19 [4.8%], respectively; p =.034) and anti‐depressants (55 [21.2%] vs. 59 [14.8%], respectively; p =.042). The restraint group had higher disease severity scores, as reflected in requirements for vasopressor support (174 [67.2%] vs. 69 [17.3%], respectively; p <.001) and need for dialysis (39 [15.1%] vs. 19 [4.8%], respectively; p <.001); higher frequency of in‐hospital anti‐psychotic treatment (60 [23.2%] vs. 11 [2.8%], respectively; p <.001); a greater tendency for agitation events and more severe agitation scores (episodes of RASS above zero [1.7 ± 4.0 vs. 0.04 ± 0.27, respectively; p <.001] and maximum RASS score [0.19 ± 1.6 vs. 0.01 ± 0.54, respectively; p <.001]). Overall, advanced age, number of ventilation days and need for dialysis were associated with increased 28‐day mortality. In the restraint group, advanced age, chronic use of diuretics and the use of dialysis during ICU admission were associated with increased mortality risk. Conclusions: Restrained patients tended to have higher morbidity and mortality during ICU and hospital stays, as well as a greater tendency for agitation events and more severe agitation scores, with an increased need for in‐hospital anti‐psychotic treatment. These findings regarding patient characteristics might be used to formulate treatment plans to reduce the rate of physical restraint in the ICU. Relevance to Clinical Practice: Because restrained ICU patients tend to have higher morbidity and mortality, treatment plans should be formulated to reduce the rate of physical restraint in the ICU.

Background: There is limited literature regarding family and staff experiences of participating in clinical trials. A qualitative study was embedded in the NAVABronch feasibility trial evaluating the effectiveness of a novel mode of ventilation, neurally adjusted ventilatory assist (NAVA), in infants with acute viral bronchiolitis. Aim: The aim of this qualitative study was to explore the experiences of parents and health care practitioners (HCPs) involved in the NAVABronch Trial. Study Design: Semi‐structured interviews were conducted with two parents and two focus groups were held with six HCPs. Results: Four themes were identified from the focus groups: (1) Creating staff engagement, (2) Education to deliver NAVA, (3) Normalizing NAVA in clinical practice (4) Creating meaningful study outcomes and (5) support of parents during the trial, this theme was generated from the parent interviews. The findings indicated the need for education regarding NAVA for HCPs which would lead to increased confidence, better guidance around the use of NAVA and the need for NAVA to be normalized and embedded into the unit culture. Parents identified the need for further support around preparation for what may happen as a result of the interventions, particularly the weaning of sedation. Conclusion: Our study indicates that staff and parents had no concerns regarding the trial methods and procedures. Relevance to Clinical Practice: Conducting clinical trials in Paediatric Intensive Care Units (PICUs) is challenging and complex. There is limited literature regarding family and staff experiences of participating in clinical trials. Understanding their experiences is crucial in ensuring trial success. [ABSTRACT FROM AUTHOR]

Background: Physical restraint is frequently used in intensive care units to prevent patients' life‐threatening removal of indwelling devices. In France, their use is poorly studied. Therefore, to evaluate the need for physical restraint, we have designed and implemented a decision support tool. Aims: Besides describing the prevalence of physical restraint use, this study aimed to assess whether the implementation of a nursing decision support tool had an impact on restraint use and to identify the factors associated with this use. Study Design: A large observational, multicentre study with a repeated one‐day point prevalence design was conducted. All adult patients hospitalized in intensive care units were eligible for this study. Two study periods were planned: before (control period) and after (intervention period) the deployment of the decision support tool and staff training. A multilevel model was performed to consider the centre effect. Results: During the control period, 786 patients were included, and 510 were in the intervention period. The prevalence of physical restraint was 28% (95% CI: 25.1%–31.4%) and 25% (95% CI: 21.5%–29.1%) respectively (χ2 = 1.35; p =.24). Restraint was applied by the nurse and/or nurse assistant in 96% of cases in both periods, mainly to wrists (89% vs. 83%, p =.14). The patient‐to‐nurse ratio was significantly lower in the intervention period (1:3.0 ± 1 vs. 1:2.7 ± 0.7, p <.001). In multivariable analysis, mechanical ventilation was associated with physical restraint (aOR [95% CI] = 6.0 [3.5–10.2]). Conclusion: The prevalence of physical restraint use in France was lower than expected. In our study, the decision support tool did not substantially impact physical restraint use. Hence, the decision support tool would deserve to be assessed in a randomized controlled trial. Relevance to Clinical Practice: The decision to physically restrain a patient could be protocolised and managed by critical care nurses. A regular evaluation of the level of sedation could allow the most deeply sedated patients to be exempted from physical restraint. [ABSTRACT FROM AUTHOR]

Background: Recent critical care guidelines recommended the evidence‐based ABCDEF care bundle for intensive care unit (ICU) patients. However, limited information is available on the implementation of the bundle in Turkish ICUs. Aim: To assess the current practices of the ABCDEF care bundle as reported by ICU nurses. Study Design: A cross‐sectional study using a web‐based survey was conducted. Researchers invited nurses with at least 1 year of ICU experience to participate by sending the link to the research questionnaires they created in Google Forms to the one ICU nurse association and one communication group of which they are members. Results: A total of 342 ICU nurses completed the survey. Although 92% of the participants performed pain assessments in their ICUs, 52.7% reported not using protocols. Based on the responses of the nurses, spontaneous awakening and breathing trials are performed in 88.8% and 92.4%, respectively, of ICUs. Fewer than half of the participants reported following a sedation protocol in their ICUs. Only 54.7% of ICU nurses surveyed reported routinely monitoring patients for delirium. It was reported that early mobilization was practised in 68.7% of ICUs, but non‐ventilated patients were mobilized more frequently (70.2%), and 9.7% of ICUs had mobilization teams. Family members were actively involved in 95% of ICUs; however, 9.7% used dedicated staff to support families and 3.5% reported that their unit was open 24 h/day for visits. Conclusions: While the implementation of most pain and sedation evaluations in ICUs were reported by nurses, many of them did not use structured delirium assessments. There is a need to encourage early mobilization programs and family participation. Relevance to Clinical Practice: Health institutions can improve patient care and outcomes by establishing and standardizing a protocol for each component of the ABCDEF care bundle in ICUs.

Objective: Atrial fibrillation (AF) is a common arrhythmia in patients at high cardiovascular risk. COVID-19 patients with underlying cardiovascular disease are at increased risk of poor clinical outcomes. In this study, we aimed to determine hospital outcomes among patients admitted with AF and COVID-19 infection. Methods: We conducted a retrospective analysis using the 2020 California State Inpatient data, including all COVID-19 hospitalizations of individuals aged ≥18. Primary outcomes were in-hospital mortality, prolonged length of stay (above the 75th percentile), vasopressor use, mechanical ventilation, and ICU admission. We compared adverse hospital outcomes between those with and without AF and used multivariable logistic regression to adjust for confounders. Results: This analysis included 94,114 COVID-19 hospitalizations, of which 9391 (10.0%) had AF. Patients with COVID-19 and AF had higher rates of adverse outcomes, including mortality (27.2% vs. 9.6%, p <.001), prolonged length of stay (40.0% vs. 27.1%, p <.001), vasopressor use (4.4% vs. 1.9%, p <.001), mechanical ventilation (19.0% vs. 9.1%, p <.001), and ICU admission (18.4% vs. 8.8%, p <.001) After multivariable adjustment, the odds of adverse outcomes remained significantly higher, including mortality adjusted odds ratio [OR], 2.04, 95% CI: 1.92–2.16), prolonged length of stay (aOR, 1.37, 95% CI: 1.31–1.44), vasopressor use (aOR, 1.98, 95% CI: 1.86–2.11), mechanical ventilation (aOR, 1.95, 95% CI: 1.72–2.20), and ICU admission (aOR, 2.01, 95% CI: 1.88–2.15). Conclusion: COVID-19 hospitalized patients frequently have underlying AF, which confers a higher risk of adverse hospital outcomes and mortality, even after adjusting for baseline comorbidities. Heightened awareness is needed in the treatment of hospitalized COVID-19 patients with AF. PLAIN LANGUAGE SUMMARY: Atrial fibrillation (AF) is a common heart rhythm disorder, especially in patients with high cardiovascular risk. This study aimed to investigate the hospital outcomes for patients admitted with both AF and COVID-19. We used data from the California State Inpatient Database for the year 2020, focusing on COVID-19 hospitalizations of adults aged 18 and older. The main outcomes studied were in-hospital death, extended hospital stays, use of vasopressor medications that raise blood pressure, need for mechanical ventilation, and admission to the intensive care unit (ICU). Our results showed that patients with both COVID-19 and AF had significantly worse outcomes compared to those without AF. Specifically, these patients had higher rates of death, extended hospital stays, vasopressor medication use, mechanical ventilation, and ICU admission, even after accounting for other health conditions. The study concludes that hospitalized COVID-19 patients with underlying AF are at a greater risk for severe complications and death. This highlights the need for increased attention and care for COVID-19 patients with AF to improve their hospital outcomes. [ABSTRACT FROM AUTHOR]

This document provides a summary of several randomized controlled trials (RCTs) that examine the use of airway pressure release ventilation (APRV) in patients with acute respiratory distress syndrome (ARDS) or at risk for ARDS. The trials evaluate different APRV settings and compare them to control groups using various outcomes such as ventilator-free days, mortality, and adverse events. The studies highlight the complexity of APRV settings and the need for further research to determine the optimal approach. The document also discusses potential sources of bias in interpreting the results of these trials. The article suggests that further research is needed to determine the appropriate use of APRV and to assess its potential benefits and risks. Current clinical guidelines do not recommend routine use of APRV for ARDS. [Extracted from the article]

To study the changes in dynamic compliance (C dyn), ventilation/perfusion (V ˙ / Q ˙) mismatch and haemodynamic variables in hypoxaemic anaesthetized horses whose PaO 2 increased following salbutamol inhalation. Retrospective, clinical, cohort study. A group of 73 client-owned horses treated with salbutamol when PaO 2 <100 mmHg (13.3 kPa) during anaesthesia. Horses were divided into two groups: responders (R), where PaO 2 after salbutamol ≥1.2 PaO 2 before treatment (i.e. ≥20% increase), and non-responders (NR), where PaO 2 after salbutamol <1.2 PaO 2 before treatment. Demographic data and intraoperative variables before treatment were compared between R and NR. C dyn , arterial to end-tidal carbon dioxide difference [P(a-E´)CO 2 ], estimated ratio of dead space to tidal volume (est.V D /V T), estimated shunt fraction (F-shunt), heart rate, systolic, mean and diastolic arterial pressure and dobutamine requirements were compared before and after treatment within R and NR. For each variable, the difference (Δ) between values pre- and posttreatment was calculated and compared between groups R and NR. Numerical data were compared using univariate or bivariate analysis and categorical data were compared using chi-square test; p < 0.05. Of the 73 horses 50 were classified as R while 23 horses were classified as NR. There was no statistical difference between R and NR for demographic data or initial intraoperative variables except for body weight [R: 531 (170–715) kg, NR: 540 (420–914) kg]. While salbutamol did not alter C dyn in either group, it significantly decreased P(a-E´)CO 2 , est.V D /V T and F-shunt in R only. ΔP(a-E´)CO 2 , Δest.V D /V T and ΔF-shunt were significantly greater in R (−17.8%, −19.0% and −24.1%, respectively) than in NR (11.5%, 6.6% and −0.3%, respectively). In hypoxaemic anaesthetized horses responding to inhaled salbutamol by a ≥1.2 increase in PaO 2 no change in C dyn was detected, but indicators of V ˙ / Q ˙ mismatch improved. [ABSTRACT FROM AUTHOR]

To compare static compliance of the respiratory system (C stRS) and the ratio of partial pressure of end-tidal to arterial carbon dioxide (P e′ CO 2 /PaCO 2), in healthy dogs using two approaches for tidal volume (V T) selection during volume-controlled ventilation: body mass based and driving pressure (ΔPaw) guided. Randomized, nonblinded, crossover, clinical trial. A total of 19 client-owned dogs anesthetized for castration and ovariohysterectomy. After a stable 10 minute baseline, each dog was mechanically ventilated with a V T selection strategy, randomized to a constant V T of 15 mL kg–1 of actual body mass (V TBW) or ΔPaw-guided V T (V TΔP) of 7–8 cmH 2 O. Both strategies used an inspiratory time of 1 second, 20% end-inspiratory pause, 4 cmH 2 O positive end-expiratory pressure and fraction of inspired oxygen of 0.4. Respiratory frequency was adjusted to maintain P e′ CO 2 between 35 and 40 mmHg. Respiratory mechanics, arterial blood gases and P e′ CO 2 /PaCO 2 were assessed. Continuous variables are presented as mean ± SD or median (interquartile range; quartiles 1–3), depending on distribution, and compared with Wilcoxon signed-rank tests. The V T was significantly higher in dogs ventilated with V TΔP than with V TBW strategy (17.20 ± 4.04 versus 15.03 ± 0.60 mL kg–1, p = 0.036). C stRS was significantly higher with V TΔP than with V TBW strategy [2.47 (1.86–2.86) versus 2.25 (1.79–2.58) mL cmH 2 O−1 kg–1, p = 0.011]. There were no differences in P e′ CO 2 /PaCO 2 between V TΔP and V TBW strategies (0.94 ± 0.06 versus 0.92 ± 0.06, p = 0.094). No discernible difference in ΔPaw was noted between the strategies. While no apparent difference was observed in the P e′ CO 2 /PaCO 2 between the V T selection strategies employed, C stRS significantly increased during the V TΔP approach. A future trial should explore if V TΔP improves perioperative gas exchange and prevents lung damage. [ABSTRACT FROM AUTHOR]

Aim: This study was designed to investigate the association between Charlson Comorbidity Index (CCI) and in‐hospital mortality and other clinical outcomes among patients with hyperglycemic crises. Method: This retrospective cohort study was conducted using data from electric medical records. A total of 1668 diabetic patients with hyperglycemic crises from six tertiary hospitals met the inclusion criteria. CCI < 4 was defined as low CCI and CCI ≥ 4 was defined as high CCI. Propensity score matching (PSM) with the 1:1 nearest neighbour matching method and the caliper value of 0.02 was used to match the baseline characteristics of patients with high CCI and low CCI to reduce the confounding bias. In‐hospital mortality, ICU admission, hypoglycemia, hypokalemia, acute kidney injury, length of stay (LOS), and hospitalisation expense between low CCI and high CCI were compared and assessed. Univariate and multivariate regression were applied to estimate the impact of CCI on in‐hospital and other clinical outcomes. Outcome: One hundred twenty‐one hyperglycemic crisis (HC) patients died with a mortality rate of 7.3%. After PSM, compared with low CCI, patients with high CCI suffered higher in‐hospital mortality, ICU admission, LOS, and hospitalisation expenses. After multivariate regression, age (aOR: 1.12, 95% confidence interval [CI]: 1.06−1.18, p < 0.001), CCI(aOR: 4.42, 95% CI: 1.56−12.53, p = 0.005), uninsured (aOR: 22.32, 95% CI: 4.26−116.94, p < 0.001), shock (aOR: 10.57, 95% CI: 1.41−79.09, p = 0.022), mechanical ventilation (aOR: 75.29, 95% CI: 12.37−458.28, p < 0.001), and hypertension (aOR: 4.34, 95% CI: 1.37−13.82, p = 0.013) were independent risk factors of in‐hospital mortality of HC patients. Besides, high CCI was an independent risk factor for higher ICU Admission (aOR: 5.91, 95% CI: 2.31−15.08, p < 0.001), hypoglycemia (aOR: 2.19, 95% CI:1.01−4.08, p = 0.049), longer LOS (aOR: 1.23, 95% CI: 1.19−2.27, p = 0.021), and higher hospitalisation expense (aOR: 2089.97, 95% CI: 193.33−3988.61, p = 0.031) of HC patients. Conclusion: CCI is associated with in‐hospital mortality, ICU admission, hypoglycemia, LOS, and hospitalisation expense of HC patients. CCI could be an ideal indicator to identify, monitor, and manage chronic comorbidities among HC patients. [ABSTRACT FROM AUTHOR]

Background: Aneurysmal subarachnoid haemorrhage (aSAH) is a life‐threatening disease with high mortality and morbidity. Patients with aSAH in Sweden are cared for at one of six neuro intensive care units (NICU) or at a general intensive care unit (ICU).This study aimed to describe the incidence, length of stay, time in ventilator and mortality for these patients. Methods: This is a retrospective, descriptive study of patients with aSAH, registered in the Swedish Intensive care Registry between 2017 and 2019. The cohort was divided in sub‐cohorts (NICU and general ICU) and regions. Mortality was analysed with logistic regression. Results: A total of 1520 patients with aSAH from five regions were included in the study. Mean age of the patients were 60.6 years and 58% were female. Mortality within 180 days of admission was 30% (n = 456) of which 17% (n = 258) died during intensive care. A majority of the patients were treated at one hospital and in one ICU (70%, n = 1062). More than half of the patients (59%, n = 897) had their first intensive care admission at a hospital with a NICU. Patients in the North region had the lowest median GCS (10) and the highest SAPS3 score (60) when admitted to NICU. Treatment with invasive mechanical ventilation differed significantly between regions; 91% (n = 80) in the region with highest proportion versus 56% (n = 94) in the region with the lowest proportion, as did mortality; 16% (n = 44) versus 8% (n = 23). No differences between regions were found regarding age, sex and length of stay. Conclusions: Patients with aSAH treated in a NICU or in an ICU in Sweden differs in characteristics. The study further showed some differences between regions which might be reduced if there were national consensus and treatment guidelines implemented. [ABSTRACT FROM AUTHOR]

Endotracheal intubation is a common lifesaving procedure that often is performed outside the operating room in a variety of clinical scenarios. Providers who perform intubation outside the operating room have variable degrees of training, skill development, and experience. A large number of studies were published in 2023 on the topic of intubations outside the operating room across a wide variety of settings and patient populations. Here, we review relevant papers on this topic published in 2023. [ABSTRACT FROM AUTHOR]

BACKGROUND: The objective of this study was to evaluate the association between noninvasive ventilation (NIV) compared with invasive ventilation and mortality in subjects with severe acute respiratory infection. METHODS: This was a retrospective multi-center study of subjects with severe acute respiratory infection treated with ventilatory support between September 2012 and June 2018. We compared the 90-d mortality of subjects managed initially with NIV (NIV group) with those managed with invasive ventilation only (invasive ventilation group), adjusting by propensity score. RESULTS: Of 383 subjects, 189 (49%) were in the NIV group and 194 (51%) were in the invasive ventilation group. Of the subjects initially treated with NIV, 117 (62%) were eventually intubated. Crude 90-d mortality was lower in the NIV group versus the invasive ventilation group (42 [22.2%] vs 77 [39.7%]; P < .001). After propensity score adjustment, NIV was associated with lower 90-d mortality than invasive ventilation (odds ratio 0.54, 95% CI 0.38-0.76; P < .001). The association of NIV with mortality compared with invasive ventilation was not different across the studied subgroups. CONCLUSIONS: In subjects with severe acute respiratory infection and acute respiratory failure, NIV was commonly used. NIV was associated with a lower 90-d mortality. The observed high failure rate suggests the need for further research to optimize patient selection and facilitate early recognition of NIV failure. [ABSTRACT FROM AUTHOR]

BACKGROUND: A protocolized extubation readiness test (ERT), including a spontaneous breathing trial (SBT), is recommended for patients who are intubated. This quality-improvement project aimed to improve peri-extubation outcomes by using a high-risk ERT protocol in intubated cardiac patients in addition to a standard-risk protocol. METHODS: After baseline data collection, we implemented a standard-risk ERT protocol (pressure support plus PEEP), followed by a high-risk ERT protocol (PEEP alone) in cardiac subjects who were intubated. The primary outcome, a composite of extubation failure and rescue noninvasive respiratory support, was compared between phases. Ventilator duration and use of postextubation respiratory support were balancing measures. RESULTS: A total of 213 cardiac subjects who were intubated were studied, with extubation failure and rescue noninvasive respiratory support occurring in 10 of 213 (4.7%) and 8 of 213 (3.8%), respectively. We observed a reduction in the composite outcome among the 3 consecutive phases (5/29 [17.2%], 10/110 [9.1%] vs 3/74 [4.1%]; P = .10), but this did not reach statistical significance. In the logistic regression model when adjusting for admission type, the high-risk ERT protocol was associated with a significant reduction of the composite outcome (adjusted odds ratio 0.20, 95% CI 0.04-0.091; P = .037), whereas the standard-risk ERT protocol was not (adjusted odds ratio 0.48, 95% CI 0.15-1.53; P = .21). This was not accompanied by a longer ventilator duration (2.0 [1.0, 3.0], 2.0 [1.0-4.0], vs adjusted odds ratio 2.0 [95% [1.0-6.0]; P = .99) or an increased use of planned noninvasive respiratory support (10/29 [35.5%], 35/110 [31.8%], vs 25/74 [33.8%]; P > .99). CONCLUSIONS: In this quality-improvement project, a high-risk ERT protocol was implemented with improvement in peri-extubation outcomes among cardiac subjects. [ABSTRACT FROM AUTHOR]

BACKGROUND: The ratio of oxygen saturation index (ROX index; or .../.../breathing frequency) has been shown to predict risk of intubation after high-flow nasal cannula (HFNC) support among adults with acute hypoxemic respiratory failure primarily due to pneumonia. However, its predictive value for other subtypes of respiratory failure is unknown. This study investigated whether the ROX index predicts liberation from HFNC or noninvasive ventilation (NIV), intubation with mechanical ventilation, or death in adults admitted for respiratory failure due to an exacerbation of COPD. METHODS: We performed a retrospective study of 260 adults hospitalized with a COPD exacerbation and treated with HFNC and/or NIV (continuous or bi-level). ROX index scores were collected at treatment initiation and predefined time intervals throughout HFNC and/or NIV treatment or until the subject was intubated or died. A ROX index score of ≥ 4.88 was applied to the cohort to determine if the same score would perform similarly in this different cohort. Accuracy of the ROX index was determined by calculating the area under the receiver operator curve. RESULTS: A total of 47 subjects (18%) required invasive mechanical ventilation or died while on HFNC/NIV. The ROX index at treatment initiation, 1 h, and 6 h demonstrated the best prediction accuracy for avoidance of invasive mechanical ventilation or death (area under the receiver operator curve 0.73 [95% CI 0.66-0.80], 0.72 [95% CI 0.65-0.79], and 0.72 [95% CI 0.63-0.82], respectively). The optimal cutoff value for sensitivity (Sn) and specificity (Sp) was a ROX index score > 6.88 (sensitivity 62%, specificity 57%). CONCLUSIONS: The ROX index applied to adults with COPD exacerbations treated with HFNC and/or NIV required higher scores to achieve similar prediction of low risk of treatment failure when compared to subjects with hypoxemic respiratory failure/pneumonia. ROX scores < 4.88 did not accurately predict intubation or death. [ABSTRACT FROM AUTHOR]

BACKGROUND: Intrapulmonary percussive ventilation (IPV) is frequently used for airway clearance, together with delivery of aerosolized medications. Drug delivery via IPV alone increases with decreasing percussion frequency and correlates with tidal volume (V
T ), whereas drug delivery via IPV during invasive ventilation is not well characterized. We hypothesized that drug delivery via IPV-invasive ventilation would differ from IPV alone due to control of ventilation by invasive ventilation. METHODS: An adult ventilator circuit was used for IPV-invasive ventilation. A normal or a diseased lung model was configured to airway resistance of 5 cm H2 O/L/s and lung compliance of 100 mL/cm H2 O or to airway resistance of 20 cm H2 O/L/s and lung compliance of 50 mL/cm H2 O, respectively. The ventilator settings were the following: pressure control continuous mandatory ventilation mode, 10 breaths/min; PEEP, 5 cm H2 O; ..., 0.21; inspiratory time, 1 s; no bias flow; and inspiratory pressure, 10 or 15 cm H2 O for the normal or the diseased lung model, respectively, to reach VT 500 mL with IPV off. Albuterol nebulized from an IPV device was captured in a filter placed before the lung model and quantitated by spectrophotometry. RESULTS: The maximum efficiency of albuterol delivery via IPV-invasive ventilation was not different from that via IPV alone (mean ± SD of loading dose, 3.7 ± 0.2% vs 4.2 ± 0.3%, respectively; P = .12). The mean ± SD albuterol delivery efficiency with IPV-invasive ventilation was lower for the diseased lung model versus the normal model (1.6 ± 0.3% vs 3.2 ± 0.5%; P < .001), which increased with decreasing percussion frequency. In contrast, the mean ± SD was lower for the normal lung model versus the diseased model (401 ± 14 mL vs 470 ± 11 mL; P < .001). CONCLUSIONS: Albuterol delivery via IPV-invasive ventilation was modulated by percussion frequency but was not increased with increasing VT . The delivery efficiency was not sufficiently high for clinical use, in part due to nebulizer retention and extrapulmonary deposition. [ABSTRACT FROM AUTHOR]- Published

BACKGROUND: Mechanical ventilation is a common life-saving procedure but can lead to serious complications, including ARDS and oxygen toxicity. Nonadherence to lung-protective ventilation guidelines is common. We hypothesized that a respiratory therapist-driven mechanical ventilation bundle could increase adherence to lung-protective ventilation and decrease the incidence of pulmonary complications in the ICU. METHODS: A respiratory therapist-driven protocol was implemented on August 1, 2018, in all adult ICUs of a Midwestern academic tertiary center. The protocol targeted low tidal volume, adequate PEEP, limiting oxygen, adequate breathing frequency, and head of the bed elevation. Adherence to lung-protective guidelines and clinical outcomes were retrospectively observed in adult subjects admitted to the ICU and on ventilation for ≥ 24 h between January 2011 and December 2019. RESULTS: We included 666 subjects; 68.5% were in the pre-intervention group and 31.5% were in the post-intervention group. After adjusting for body mass index and intubation indication, a significant increase in overall adherence to lung-protective ventilation guidelines was observed in the post-intervention period (adjusted odds ratio 2.48, 95% CI 1.73-3.56). Fewer subjects were diagnosed with ARDS in the post-intervention group (adjusted odds ratio 0.22, 95% CI 0.08-0.65) than in the pre-intervention group. There was no difference in the incidence of ventilator-associated pneumonia, ventilator-free days, ICU mortality, or death within 1 month of ICU discharge. CONCLUSIONS: A respiratory therapist-driven protocol increased adherence to lung-protective mechanical ventilation guidelines in the ICU and was associated with decreased ARDS incidence.

Background: Sepsis is a complex condition with high morbidity and mortality. Prompt treatment can improve survival, but for survivors the risk of deterioration and readmission remains high. Little is known about the association between discharge setting and readmission among sepsis survivors. Objective: To examine 30-day hospital readmission rates in adult sepsis survivors by the type of setting to which patients were discharged. Methods: The Medical Information Mart for Intensive Care database was used to identify adult sepsis survivors and evaluate 30-day readmission by discharge setting. A χ
2 contingency analysis was used with each factor and presence/absence of readmission. The Kruskal-Wallis test was used to compare readmissions across discharge settings. Results: From our sample (N = 7107; mean age 66.5 years; 46.2% women), 23.6% (n = 1674) were readmitted within 30 days and of those readmitted, 30% were readmitted between 1 and 3 times. Discharge setting (P <.001) and age (P =.02) were significantly associated with readmission, but sex, ethnicity, and insurance type were not. High numbers of readmissions were seen in patients discharged to skilled nursing facilities (29.6%), home health care (26.9%), and home (15.0%). Similar high comorbidity burden and acuteness of illness were seen in patients discharged to these settings. Conclusions: Sepsis survivors discharged to skilled nursing facilities, home health care, and home are at high risk for 30-day readmission. The rates of readmission from home health care and home settings were alarming. Often patients are discharged to inappropriate settings, placing them at risk for residual sepsis and readmission. Future research should focus on appropriate timing of hospital discharge and transition to the most appropriate discharge setting. [ABSTRACT FROM AUTHOR]- Published

Purpose: Acute allergic reactions may occur in susceptible individuals following exposure to various allergens. Obesity is linked to allergic reactions, and weight loss from bariatric surgery may attenuate the severity of certain conditions such as airway hyperresponsiveness in asthma. This retrospective observational study investigates associations between prior bariatric surgery and lower risk for life-threatening conditions in patients hospitalized with acute allergic reactions and anaphylaxis. Materials and Methods: Adults ≥ 18 years old diagnosed with morbid obesity and admitted to US hospitals with acute allergic reactions/anaphylaxis were included. All data were extracted from the US Nationwide Inpatient Sample (NIS) database 2005–2018. Patients without information on in-hospital mortality, discharge destination, hospital costs, and length of stay (LOS) were excluded. Patients were divided into two groups based on prior bariatric surgery or not. All diagnoses were verified through ICD-9 and ICD-10 codes. Between-group differences and associations between variables were evaluated using logistic regression analysis. Results: After matching, patients with prior bariatric surgery had significantly lower proportions of any life-threatening morbidity (37.2% vs. 47.4%), respiratory distress or failure (11.2% vs. 17.0%), pneumonia or severe infection (7.4% vs. 10.2%), sepsis/septic shock (15.2% vs. 20.9%), intubation and mechanical ventilation (11.2% vs. 14.6%), prolonged LOS (10.3% vs. 20.6%) and unfavorable discharge (6.9% vs. 12.5%) than those without prior bariatric surgery. Conclusion: Prior bariatric surgery predicts a lower risk of life-threatening morbidity and prolonged LOS among adults hospitalized for acute allergic reaction and anaphylaxis. Future prospective studies are warranted to confirm the present findings and reveal underlying mechanisms. [ABSTRACT FROM AUTHOR]

Background Mechanical ventilation, as an important respiratory support, plays an important role in general anesthesia and it is the cornerstone of intraoperative management of surgical patients. Different from spontaneous respiration, intraoperative mechanical ventilation can lead to postoperative lung injury, and its impact on surgical mortality cannot be ignored. Postoperative lung injury increases hospital stay and is related to preoperative conditions, anesthesia time, and intraoperative ventilation settings. Method Through reading literature and research reports, the relationship between perioperative input parameters and output parameters related to mechanical ventilation and ventilator-related complications was reviewed, providing reference for the subsequent setting of input parameters of mechanical ventilation and new ventilation strategies. Results The parameters of inspiratory pressure rise time and inspiratory time can change the gas distribution, gas flow rate and airway pressure into the lungs, but there are few clinical studies on them. It can be used as a prospective intervention to study the effect of specific protective ventilation strategies on pulmonary complications after perioperative anesthesia. Conclusion There are many factors affecting lung function after perioperative mechanical ventilation. Due to the difference of human body, the ventilation parameters suitable for each patient are different, and the deviation of each ventilation parameter can lead to postoperative pulmonary complications. Inspiratory pressure rise time and inspiratory time will be used as the new ventilation strategy. [ABSTRACT FROM AUTHOR]

Background: The South Korean government implemented a multidisciplinary nutritional support team (NST) system to focus on the proper evaluation and supply of nutritional status in hospitalized patients who are at a higher risk of malnutrition. Methods: This nationwide population-based cohort study included patients diagnosed with sepsis who were admitted to hospitals from 2016 to 2020. The NST should consist of four professional personnel (physicians, full-time nurses, full-time pharmacists, and full-time clinical dietitians). The NST group included patients with sepsis admitted to a hospital with an NST system, whereas the non-NST group included patients with sepsis admitted to a hospital without an NST system. Results: A total of 323,841 patients with sepsis were included in the final analysis, and 120,274 (37.1%) admitted to a hospital with an NST system were included in the NST group. In the multivariable Cox regression analysis, the NST group showed a 15% lower 90-day mortality than the non-NST group (hazard ratio [HR]:0.85, 95% confidence interval [CI]:0.83, 0.86; P < 0.001). The NST group shows 11% lower 1-year all-cause mortality than the non-NST group (HR:0.89, 95% CI:0.87, 0.90; P < 0.001). In subgroup analyses, a more evident association of the NST group with lower 90-day mortality was shown in the intensive care unit admission group and age ≥65 years old group. Conclusions: Multidisciplinary NST intervention is associated with improved survival outcomes in patients with sepsis. Moreover, this association was more evident in patients with sepsis aged ≥65 years old who were admitted to the ICU. [ABSTRACT FROM AUTHOR]

ALCOHOL withdrawal syndrome ,INTENSIVE care units ,LENGTH of stay in hospitals ,PHENOBARBITAL ,ARTIFICIAL respiration - Abstract
Background: Phenobarbital may offer advantages over benzodiazepines for severe alcohol withdrawal syndrome (SAWS), but its impact on clinical outcomes has not been fully elucidated. Objective: The purpose of this study was to determine the clinical impact of phenobarbital versus benzodiazepines for SAWS. Methods: This retrospective cohort study compared phenobarbital to benzodiazepines for the management of SAWS for patients admitted to progressive or intensive care units (ICUs) between July 2018 and July 2022. Patients included had a history of delirium tremens (DT) or seizures, Clinical Institute Withdrawal Assessment of Alcohol-Revised (CIWA-Ar) >15, or Prediction of Alcohol Withdrawal Severity Scale (PAWSS) score ≥4. The primary outcome was hospital length of stay (LOS). Secondary outcomes included progressive or ICU LOS, incidence of adjunctive pharmacotherapy, and incidence/duration of mechanical ventilation. Results: The final analysis included 126 phenobarbital and 98 benzodiazepine encounters. Patients treated with phenobarbital had shorter median hospital LOS versus those treated with benzodiazepines (2.8 vs 4.7 days; P < 0.0001); a finding corroborated by multivariable analysis. The phenobarbital group also had shorter median progressive/ICU LOS (0.7 vs 1.3 days; P < 0.0001), and lower incidence of dexmedetomidine (P < 0.0001) and antipsychotic initiation (P < 0.0001). Fewer patients in the phenobarbital group compared to the benzodiazepine group received new mechanical ventilation (P = 0.045), but median duration was similar (1.2 vs 1.6 days; P = 1.00). Conclusion and relevance: Scheduled phenobarbital was associated with decreased hospital LOS compared to benzodiazepines for SAWS. This was the first study to compare outcomes of fixed-dose, nonoverlapping phenobarbital to benzodiazepines in patients with clearly defined SAWS and details a readily implementable protocol.

Background Methods Results Conclusion This Rapid Practice Guideline (RPG) aimed to provide evidence‐based recommendations for ketamine analgo‐sedation (monotherapy and adjunct) versus non‐ketamine sedatives or usual care in adult intensive care unit (ICU) patients on invasive mechanical ventilation (iMV) and to identify knowledge gaps for future research.The RPG panel comprised 23 multinational multidisciplinary panelists, including a patient representative. An up‐to‐date systematic review and meta‐analysis constituted the evidence base. The Grading Recommendations, Assessment, Development, and Evaluation approach, and the evidence‐to‐decision framework were used to assess the certainty of evidence and to move from evidence to decision/recommendation. The panel provided input on the balance of the desirable and undesirable effects, certainty of evidence, patients' values and preferences, costs, resources, equity, feasibility, acceptability, and research priorities.Data from 17 randomized clinical trials (n = 898) and nine observational studies (n = 1934) were included. There was considerable uncertainty about the desirable and undesirable effects of ketamine monotherapy for analgo‐sedation. The evidence was very low certainty and downgraded for risk of bias, indirectness, and inconsistency. Uncertainty or variability in values and preferences were identified. Costs, resources, equity, and acceptability were considered varied. Adjunctive ketamine therapy had no effect on mortality (within 28 days) (relative risk [RR] 0.99; 95% confidence interval [CI] 0.76 to 1.27; low certainty), and may slightly reduce iMV duration (days) (mean difference [MD] −0.05 days; 95% CI −0.07 to −0.03; low certainty), and uncertain effect on the cumulative dose of opioids (mcg/kg/h morphine equivalent) (MD −11.6; 95% CI −20.4 to −2.7; very low certainty). Uncertain desirable effects (cumulative dose of sedatives and vasopressors) and undesirable effects (adverse event rate, delirium, arrhythmia, hepatotoxicity, hypersalivation, use of physical restraints) were also identified. A possibility of important uncertainty or variability in patient‐important outcomes led to a balanced effect that favored neither the intervention nor the comparison. Cost, resources, and equity were considered varied.The RPG panel provided two conditional recommendations and suggested (1) against using ketamine as monotherapy analgo‐sedation in critically ill adults on iMV when other analgo‐sedatives are available; and (2) using ketamine as an adjunct to non‐ketamine usual care sedatives (e.g., opioids, propofol, dexmedetomidine) or continuing with non‐ketamine usual care sedatives alone. Large‐scale trials should provide additional evidence. [ABSTRACT FROM AUTHOR]

CHEST compressions ,CARDIOPULMONARY resuscitation ,ARTIFICIAL respiration ,CARDIAC arrest ,VENTILATION - Abstract
For many years, ventilation has been an essential part of advanced life support (ALS) in cardiopulmonary resuscitation (CPR). Nevertheless, there is little evidence about the best method of ventilation during resuscitation for both out-of-hospital cardiac arrest (OHCA) and inhospital cardiac arrest (IHCA) patients. Effective ventilation is one of the two main keys to successful resuscitation. In this context, the question always arises as to which airway management, along with which ventilation mode, constitutes the best strategy. Conventional ventilation modes are not designed for cardiac arrest and show important limitations that must be considered when used in CPR. Manual ventilation without the use of an automated transport ventilator (ATV) could be shown to be uncontrolled in applied volumes and pressures and should be avoided. Mechanical ventilation with an ATV is therefore superior to manual ventilation, but both volume- and pressure-controlled ventilation modes are significantly influenced by chest compressions. With the newly designed chest compression synchronized ventilation (CCSV), a special ventilation mode for resuscitation is available. Further research should be conducted to obtain more evidence of the effect of ventilation during CPR on outcomes following OHCA and not only about how to secure the airway for ventilation during CPR.

Background: This study aimed to develop prognostic models for predicting the need for invasive mechanical ventilation (IMV) in intensive care unit (ICU) patients with COVID-19 and compare their performance with the Respiratory rate-OXygenation (ROX) index. Methods: A retrospective cohort study was conducted using data collected between March 2020 and August 2021 at three hospitals in Rio de Janeiro, Brazil. ICU patients aged 18 years and older with a diagnosis of COVID-19 were screened. The exclusion criteria were patients who received IMV within the first 24 h of ICU admission, pregnancy, clinical decision for minimal end-of-life care and missing primary outcome data. Clinical and laboratory variables were collected. Multiple logistic regression analysis was performed to select predictor variables. Models were based on the lowest Akaike Information Criteria (AIC) and lowest AIC with significant p values. Assessment of predictive performance was done for discrimination and calibration. Areas under the curves (AUC)s were compared using DeLong's algorithm. Models were validated externally using an international database. Results: Of 656 patients screened, 346 patients were included; 155 required IMV (44.8%), 191 did not (55.2%), and 207 patients were male (59.8%). According to the lowest AIC, arterial hypertension, diabetes mellitus, obesity, Sequential Organ Failure Assessment (SOFA) score, heart rate, respiratory rate, peripheral oxygen saturation (SpO2), temperature, respiratory effort signals, and leukocytes were identified as predictors of IMV at hospital admission. According to AIC with significant p values, SOFA score, SpO2, and respiratory effort signals were the best predictors of IMV; odds ratios (95% confidence interval): 1.46 (1.07–2.05), 0.81 (0.72–0.90), 9.13 (3.29–28.67), respectively. The ROX index at admission was lower in the IMV group than in the non-IMV group (7.3 [5.2–9.8] versus 9.6 [6.8–12.9], p < 0.001, respectively). In the external validation population, the area under the curve (AUC) of the ROX index was 0.683 (accuracy 63%), the AIC model showed an AUC of 0.703 (accuracy 69%), and the lowest AIC model with significant p values had an AUC of 0.725 (accuracy 79%). Conclusions: In the development population of ICU patients with COVID-19, SOFA score, SpO2, and respiratory effort signals predicted the need for IMV better than the ROX index. In the external validation population, although the AUCs did not differ significantly, the accuracy was higher when using SOFA score, SpO2, and respiratory effort signals compared to the ROX index. This suggests that these variables may be more useful in predicting the need for IMV in ICU patients with COVID-19. ClinicalTrials.gov identifier: NCT05663528. [ABSTRACT FROM AUTHOR]

Background: By controlling hypercapnia, respiratory acidosis, and associated consequences, extracorporeal CO2 removal (ECCO2R) has the potential to facilitate ultra-protective lung ventilation (UPLV) strategies and to decrease injury from mechanical ventilation. We convened a meeting of European intensivists and nephrologists and used a modified Delphi process to provide updated insights into the role of ECCO2R in acute respiratory distress syndrome (ARDS) and to identify recommendations for a future randomized controlled trial. Results: The group agreed that lung protective ventilation and UPLV should have distinct definitions, with UPLV primarily defined by a tidal volume (VT) of 4–6 mL/kg predicted body weight with a driving pressure (ΔP) ≤ 14–15 cmH2O. Fourteen (93%) participants agreed that ECCO2R would be needed in the majority of patients to implement UPLV. Furthermore, 10 participants (majority, 63%) would select patients with PaO2:FiO2 > 100 mmHg (> 13.3 kPa) and 14 (consensus, 88%) would select patients with a ventilatory ratio of > 2.5–3. A minimum CO2 removal rate of 80 mL/min delivered by continuous renal support machines was suggested (11/14 participants, 79%) for this objective, using a short, double-lumen catheter inserted into the right internal jugular vein as the preferred vascular access. Of the participants, 14/15 (93%, consensus) stated that a new randomized trial of ECCO2R is needed in patients with ARDS. A ΔP of ≥ 14–15 cmH2O was suggested by 12/14 participants (86%) as the primary inclusion criterion. Conclusions: ECCO2R may facilitate UPLV with lower volume and pressures provided by the ventilator, while controlling respiratory acidosis. Since recent European Society of Intensive Care Medicine guidelines on ARDS recommended against the use of ECCO2R for the treatment of ARDS outside of randomized controlled trials, new trials of ECCO2R are urgently needed, with a ΔP of ≥ 14–15 cmH2O suggested as the primary inclusion criterion.

Background: Prolonged mechanical ventilation is associated with an increased risk of mortality in these patients. However, there exists a significant clinical need for novel indicators that can complement traditional weaning evaluation methods and effectively guide ventilator weaning. Objectives: To investigate the specific relationship between mechanical power normalized to dynamic lung compliance (Cdyn-MP) and weaning outcomes in patients on mechanical ventilation for more than 24 hours, as well as those who underwent a T-tube weaning strategy. Methods: A retrospective cohort study was conducted using the Medical Information Mart for Intensive Care-IV v1.0 database (MIMIC-IV v1.0). Patients who received invasive mechanical ventilation for more than 24 hours and underwent a T-tube ventilation strategy for weaning were enrolled. Patients were divided into two groups based on their weaning outcome: weaning success and failure. Ventilation parameter data were collected every 4 hours during the first 24 hours before the first spontaneous breathing trial (SBT). Results: Of all the 3,695 patients, 1,421 (38.5%) experienced weaning failure. Univariate logistic regression analysis revealed that the risk of weaning failure increased as the Cdyn-MP level rose (OR 1.34, 95% CI 1.31–1.38, P<0.001). After adjusting for age, body mass index, disease severity, and pre-weaning disease status, patients with high Cdyn-MP quartiles in the 4 hours prior to the SBT had a significantly greater risk of weaning failure than those with low Cdyn-MP quartiles (odds ratio 10.37, 95% CI 7.56–14.24). These findings were robust and consistent in both subgroup and sensitivity analyses. Conclusion: The increased Cdyn-MP before SBT was independently associated with a higher risk of weaning failure in mechanically ventilated patients. Cdyn-MP has the potential to be a useful indicator for guiding the need for ventilator weaning and complementing traditional weaning evaluation methods. [ABSTRACT FROM AUTHOR]

Objectives: We aimed to evaluate the ability of the parasternal intercostal (PIC) thickening fraction during spontaneous breathing trial (SBT) to predict the need for reintubation within 48 h after extubation in surgical patients with sepsis. Methods: This prospective observational study included adult patients with sepsis who were mechanically ventilated and indicated for SBT. Ultrasound measurements of the PIC thickening fraction and diaphragmatic excursion (DE) were recorded 15 min after the start of the SBT. After extubation, the patients were followed up for 48 h for the need for reintubation. The study outcomes were the ability of the PIC thickening fraction (primary outcome) and DE to predict reintubation within 48 h of extubation using area under receiver characteristic curve (AUC) analysis. The accuracy of the model including the findings of right PIC thickening fraction and right DE was also assessed using the current study cut-off values. Multivariate analysis was performed to identify independent risk factors for reintubation. Results: We analyzed data from 49 patients who underwent successful SBT, and 10/49 (20%) required reintubation. The AUCs (95% confidence interval [CI]) for the ability of right and left side PIC thickening fraction to predict reintubation were 0.97 (0.88–1.00) and 0.96 (0.86–1.00), respectively; at a cutoff value of 6.5–8.3%, the PIC thickening fraction had a negative predictive value of 100%. The AUCs for the PIC thickening fraction and DE were comparable; and both measures were independent risk factors for reintubation. The AUC (95% CI) of the model including the right PIC thickening fraction > 6.5% and right DE ≤ 18 mm to predict reintubation was 0.99 (0.92–1.00), with a positive predictive value of 100% when both sonographic findings are positive and negative predictive value of 100% when both sonographic findings are negative. Conclusions: Among surgical patients with sepsis, PIC thickening fraction evaluated during the SBT is an independent risk factor for reintubation. The PIC thickening fraction has an excellent predictive value for reintubation. A PIC thickening fraction of ≤ 6.5–8.3% can exclude reintubation, with a negative predictive value of 100%. Furthermore, a combination of high PIC and low DE can also indicate a high risk of reintubation. However, larger studies that include different populations are required to replicate our findings and validate the cutoff values. [ABSTRACT FROM AUTHOR]

Background: Our study aimed to describe the group of severe COVID-19 patients at an institutional level, and determine factors associated with different outcomes. Methods: A retrospective chart review of patients admitted with severe acute hypoxic respiratory failure due to COVID-19 infection. Based on outcomes, we categorized 3 groups of severe COVID-19: (1) Favorable outcome: progressive care unit admission and discharge (2) Intermediate outcome: ICU care (3) Poor outcome: in-hospital mortality. Results: Eighty-nine patients met our inclusion criteria; 42.7% were female. The average age was 59.7 (standard deviation (SD):13.7). Most of the population were Caucasian (95.5%) and non-Hispanic (91.0%). Age, sex, race, and ethnicity were similar between outcome groups. Medicare and Medicaid patients accounted for 62.9%. The average BMI was 33.5 (SD:8.2). Moderate comorbidity was observed, with an average Charlson Comorbidity index (CCI) of 3.8 (SD:2.6). There were no differences in the average CCI between groups(p = 0.291). Many patients (67.4%) had hypertension, diabetes (42.7%) and chronic lung disease (32.6%). A statistical difference was found when chronic lung disease was evaluated; p = 0.002. The prevalence of chronic lung disease was 19.6%, 27.8%, and 40% in the favorable, intermediate, and poor outcome groups, respectively. Smoking history was associated with poor outcomes (p = 0.04). Only 7.9% were fully vaccinated. Almost half (46.1%) were intubated and mechanically ventilated. Patients spent an average of 12.1 days ventilated (SD:8.5), with an average of 6.0 days from admission to ventilation (SD:5.1). The intermediate group had a shorter average interval from admission to ventilator (77.2 hours, SD:67.6), than the poor group (212.8 hours, SD:126.8); (p = 0.001). The presence of bacterial pneumonia was greatest in the intermediate group (72.2%), compared to the favorable group (17.4%), and the poor group (56%); this was significant (p<0.0001). In-hospital mortality was seen in 28.1%. Conclusion: Most patients were male, obese, had moderate-level comorbidity, a history of tobacco abuse, and government-funded insurance. Nearly 50% required mechanical ventilation, and about 28% died during hospitalization. Bacterial pneumonia was most prevalent in intubated groups. Patients who were intubated with a good outcome were intubated earlier during their hospital course, with an average difference of 135.6 hours. A history of cigarette smoking and chronic lung disease were associated with poor outcomes. [ABSTRACT FROM AUTHOR]

Background: Severe hyperlactatemia (lactate level ≥ 10 mmol/L) is associated with high mortality rates in critically ill patients. However, there is limited data on emergency department (ED) patients. We aimed to investigate the clinical characteristics, etiology and outcomes of patients with severe hyperlactatemia in the ED setting. Methods: A retrospective cohort study was conducted at a tertiary care hospital in Thailand. We included adult patients with a venous lactate sample taken in the ED within one hour. We excluded patients after out-of-hospital cardiac arrest, transferred to/from another hospital or those with missing clinical data. Mortality rates were evaluated among patients with increasing degrees of lactate elevation and among patients with severe hyperlactatemia, stratified by causative etiology. Results: We analyzed venous lactate levels in 40,047 patients, with 26,680 included in the analysis. Among these, 1.7% had severe hyperlactatemia (lactate ≥ 10 mmol/L), 10.5% moderate (4–9.99 mmol/L), 28.8% mild (2—3.99 mmol/L), and 59.0% normal levels (< 2 mmol/L). Severe hyperlactatemia was associated with high mortality rates of 29%, 37%, and 38% at 7, 28, and 60 days respectively, significant ICU admissions and mechanical ventilation rates. Patients with severe hyperlactatemia were stratified into high (> 50% mortality), moderate (21–50%), and low (< 20%) 28-day mortality risk groups. High-risk conditions included non-septic shock, traumatic injuries/burns, and neurological issues, with mortality rates of 51.1%, 61.8%, and 57.1%, respectively. In the moderate risk group, namely infection without shock showed a high prevalence, with a mortality rate of 36%. In the low-risk group, seizures and fainting were associated with lower mortality, exhibiting mortality rates of 0%. Conclusions: Severe hyperlactatemia is associated with higher rates of ICU admission and mortality compared to other degrees of lactate elevation in a general ED population. However, mortality rates can vary considerably, depending on the underlying etiology associated with different primary diagnoses. [ABSTRACT FROM AUTHOR]

To explore preoperative and operative risk factors for red blood cell (RBC) transfusion requirements during liver transplantation (LT) and up to 24 h afterwards. We evaluated the associations between risk factors and units of RBC transfused in 176 LT patients using a log-binomial regression model. Relative risk was adjusted for age, sex, and the model for end-stage liver disease score (MELD) (adjustment 1) and baseline hemoglobin concentration (adjustment 2). Forty-six patients (26.14%) did not receive transfusion. Grafts from cardiac-death donors were used in 32.61% and 31.54% of non-transfused and transfused patients, respectively. The transfused group required more reoperation for bleeding (P = 0.035), longer mechanical ventilation after LT (P < 0.001), and longer ICU length of stay (P < 0.001). MELD and hemoglobin concentrations determined RBC requirements. For each unit of increase in the MELD score, 2% more RBC units were transfused, and non-transfusion was 0.83-fold less likely. For each 10-g/L higher hemoglobin concentration at baseline, 16% less RBC transfused, and non-transfusion was 1.95-fold more likely. Ascites was associated with 26% more RBC transfusions. With an increase of 2 mm from the baseline in the A10Fibtem measurement of maximum clot firmness, non-transfusion was 1.14-fold more likely. A 10-min longer cold ischemia time was associated with 1% more RBC units transfused, and the presence of post-reperfusion syndrome with 45% more RBC units. We conclude that preoperative correction of anemia should be included in LT. An intervention to prevent severe hypotension and fibrinolysis during graft reperfusion should be explored.

Background: Ventilation management may differ between COVID–19 ARDS (COVID–ARDS) patients and patients with pre–COVID ARDS (CLASSIC–ARDS); it is uncertain whether associations of ventilation management with outcomes for CLASSIC–ARDS also exist in COVID–ARDS. Methods: Individual patient data analysis of COVID–ARDS and CLASSIC–ARDS patients in six observational studies of ventilation, four in the COVID–19 pandemic and two pre–pandemic. Descriptive statistics were used to compare epidemiology and ventilation characteristics. The primary endpoint were key ventilation parameters; other outcomes included mortality and ventilator–free days and alive (VFD–60) at day 60. Results: This analysis included 6702 COVID–ARDS patients and 1415 CLASSIC–ARDS patients. COVID–ARDS patients received lower median VT (6.6 [6.0 to 7.4] vs 7.3 [6.4 to 8.5] ml/kg PBW; p < 0.001) and higher median PEEP (12.0 [10.0 to 14.0] vs 8.0 [6.0 to 10.0] cm H2O; p < 0.001), at lower median ΔP (13.0 [10.0 to 15.0] vs 16.0 [IQR 12.0 to 20.0] cm H2O; p < 0.001) and higher median Crs (33.5 [26.6 to 42.1] vs 28.1 [21.6 to 38.4] mL/cm H2O; p < 0.001). Following multivariable adjustment, higher ΔP had an independent association with higher 60–day mortality and less VFD–60 in both groups. Higher PEEP had an association with less VFD–60, but only in COVID–ARDS patients. Conclusions: Our findings show important differences in key ventilation parameters and associations thereof with outcomes between COVID–ARDS and CLASSIC–ARDS.

Background: Diaphragmatic dysfunction correlates with weaning failure, highlighting the need to independently assess the diaphragm's effects on weaning. We modified the rapid shallow breathing index (RSBI), a predictor of successful weaning, by incorporating temporal variables into existing ultrasound-derived diaphragm index to create a simpler index closer to tidal volume. Methods: We conducted a prospective observational study of patients who underwent a spontaneous breathing trial in the medical intensive care unit (ICU) at Severance Hospital between October 2022 and June 2023. Diaphragmatic displacement (DD) and diaphragm inspiratory time (Ti) were measured using lung ultrasonography. The modified RSBI was defined as follows: respiratory rate (RR) divided by DD was defined as D-RSBI, and RR divided by the sum of the products of DD and Ti on both sides was defined as DTi-RSBI. Results: Among the sonographic indices, DTi-RSBI had the highest area under the receiver operating characteristic (ROC) curve of 0.774 in ROC analysis, and a correlation was found between increased DTi-RSBI and unsuccessful extubation in a multivariable logistic regression analysis (adjusted odds ratio 0.02, 95% confidence interval 0.00–0.97). Conclusions: The DTi-RSBI is beneficial in predicting successful weaning in medical ICU patients. [ABSTRACT FROM AUTHOR]
