Objectives: To explore clinician perspectives on key actionable processes of care that may improve outcomes and experience of patients experiencing a prolonged (over 7 days) intensive care unit stay, and their family members., Research Methodology: A descriptive qualitative interview study in the United Kingdom. We conducted online semi-structured interviews using video conferencing software (October 2020-August 2022). We used purposive sampling ensuring participation from a broad range of professions representing the interprofessional team in the United Kingdom. We used Framework Analysis methods to group actionable processes into the six themes of person-centred care. Analyses were informed by our previous scoping review and previous interviews with former patients and family members., Findings: We interviewed 24 staff participants and identified 36 actionable processes of care under six themes of person-centred care. Processes relating to communication (both establishing an effective communication method for the patient and staff communication with the patient and family), continuity of staff and care plans, and personalising the environment and routines, and allowing flexible family visiting were most frequently articulated. These processes were perceived as having a multifaceted impact on patient and family wellbeing, for example family visiting helping patient and family emotional wellbeing and staff communication with family; and establishing an effective communication method for patients reduced their anxiety, enhanced their involvement in their care and allowed staff to include them in ward rounds more efficiently., Conclusion: We identified 36 actionable processes of care from interviews with intensive care staff, with an emphasis on enhancing patient autonomy through optimising communication and involvement in decision-making, participation of family, and continuity of staff and care plans., Implications for Clinical Practice: These 36 actionable processes of care will contribute to future development of quality improvement tools, which will be used to standardise the care of prolonged-stay intensive care patients and their families., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2023.

Aim: To understand the status quo of multiprofessional and multidisciplinary collaboration for early mobilization of mechanically ventilated patients in Chinese ICUs and identify any factors that may influence this practice. Design: A multi‐centre cross‐sectional survey. Methods: From October to November 2022, the convenience sampling method was used to select ICU multiprofessional and multidisciplinary early mobility members (including physicians, nurses and physiotherapists) from 27 tertiary general hospitals in 14 provinces, cities and autonomous regions of China. They were asked to complete an author‐developed questionnaire on the status of collaboration and the Assessment of Inter‐professional Team Collaboration Scale. A multiple linear regression model was used to analyse the factors associated with the level of collaboration. Results: Physicians, nurses and physiotherapists mostly suffered from the lack of normative protocols, unclear division of responsibilities and unclear multiprofessional and multidisciplinary teams when using a collaborative approach to early activities. Multiple linear regression analysis showed that the number of ICU patients managed, the existence of norms and processes, the attitude of colleagues around them, the establishment of a team, communication methods and activity leaders were significant influences on the level of collaboration among members of the multiprofessional and multidisciplinary early activities. Conclusion: The collaboration of multiprofessional and multidisciplinary early activity members for mechanically ventilated patients in the ICU remains unclear, and the collaboration strategy needs to be constructed and improved, taking into account China's human resources and each region's economic development level. Impact: This study investigates the collaboration status of multiprofessional and multidisciplinary activity members from the perspective of teamwork, analyses the reasons affecting the level of collaboration and helps to develop better teamwork strategies to facilitate the implementation of early activities. Patient or Public Contribution: The participants in this study were multiprofessional and multidisciplinary medical staff who performed early activities for ICU patients. [ABSTRACT FROM AUTHOR]

Background: The significance of computed tomography (CT)-based volume measurement of the inferior vena cava (IVC) in the treatment and prognosis of trauma patients is not yet fully understood. The conflicting results that have been reported may be attributable to differences in injury severity and the use of different measurement methods, including IVC index and volumetry. The purpose of this study was to determine the relationship between IVC volume and red blood cell (RBC) transfusion and mortality in intubated trauma patients who were stable enough for initial CT imaging. Methods: A retrospective analysis was conducted on all consecutive trauma patients who underwent emergency tracheal intubation and mechanical ventilation before initial whole-body CT imaging at a level-1 trauma center over a 12-year period (2008–2019). The IVC volume was determined on initial trauma CT and included in multivariable models with demographic and diagnostic data. Associations of overall RBC transfusion, massive transfusion, 24-h mortality, and 30-day mortality were assessed using logistic regression analyses and Cox proportional hazard models. Results: A total of 438 patients (75.3% male) with a median age of 50 years, and a median injury severity score (ISS) of 26 points were included in the analysis. Most of the patients (97.5%) had suffered from blunt trauma mechanisms. Median IVC volume was 36.25 cm3, and RBC transfusion and massive transfusion were performed in 197 and 90 patients, respectively. The 24-h and 30-day mortality rates were 7.3% and 23.3%, respectively. VCI volume was found to be independently associated with the necessity of RBC transfusion and 24-h mortality (OR 0.98, 95% CI 0.96–0.99, p = 0.01 and HR 0.96, 95% CI 0.93–0.99, p = 0.025, respectively), while associations with massive transfusion and 30-day mortality were not statistically significant in multivariable analyses. Conclusion: Initial IVC volume may serve as a predictor of patients at risk for overall RBC transfusion requirements and 24-h mortality, suggesting the possibility of its diagnostic efficacy in short-term outcomes. Further studies are needed to confirm these findings. [ABSTRACT FROM AUTHOR]

Background: Acute exacerbations of COPD (AECOPD) are common and significantly contribute to mortality in patients with COPD. Prognostic scores can assist clinicians in making tailored decisions to manage AECOPD. In the current study, we therefore aimed to evaluate the performance of the Noninvasive Ventilation Outcomes (NIVO) score, originally designed to assess in-ICU mortality, in predicting 1 year mortality and NIV failure in AECOPD. Methods: This retrospective study analyzed data from patients hospitalized for AECOPD requiring mechanical ventilation between January 1st, 2018, and December 31st, 2022. Mortality was assessed at the end of ICU stay and 1 year after admission, while NIV failure was defined as intubation or death without intubation. Results: Among 302 ICU admissions of COPD patients, 190 patients with AECOPD requiring mechanical ventilation were included. Of these, 44 (23%) died in the ICU, 62 out of 184 (34%) failed NIV, and 78 (41%) died within 1 year of admission. Patients who died in ICU or experienced NIV failure had more severe COPD and more impaired blood gas parameters at admission. The NIVO score demonstrated an AUC of 0.68 in predicting 1-year mortality and an AUC of 0.85 in predicting NIV failure. A NIVO score over 7 was associated with higher 1-year mortality and NIV failure (HR of 4.4 [1.8–10.9] and 41.6 [5.6–307.9], respectively). Conclusion: Beyond predicting in-ICU mortality, the NIVO-score is a reliable tool in predicting 1-year mortality and NIV failure in AECOPD. [ABSTRACT FROM AUTHOR]

Background: In Venezuela, the predominant vaccines administered are BBIBP-CorV and Gam-COVID-Vac. Despite robust evidence from randomized clinical trials validating the effectiveness of COVID-19 vaccines in mitigating hospitalization and mortality, there is still a lack of post-authorization safety studies conducted within this demographic population. Methods: A prospective observational study from October 5, 2021 to March 31, 2022 encompassed COVID-19 vaccinated and unvaccinated patients from four sentinel hospitals in Venezuela. Patient lethality was predicted using Charlson Comorbidity index. Clinical outcomes were assessed through WHO's COVID-19 Clinical Progression Scale. Results: Out of the 175 patients assessed, 85 (48.6%) were vaccinated. The median Charlson Comorbidity index was 3 points, with no statistically significant differences observed between the groups (p = 0.2). A total of 50 (28.6%) patients died during the study period, with higher proportion of deaths in unvaccinated patients (35.6% vs. 21.2%, p = 0.035). Advanced age (OR = 1.043, 95% CI = 1.015–1.071, p = 0.002) was associated with increased death risk, whereas vaccination against COVID-19 (OR = 0.428, 95% CI = 0.185–0.99, p = 0.047), high oxygen saturation (OR = 0.964, 95% CI = 0.934–0.995, p = 0.024), and enoxaparin administration (OR = 0.292, 95% CI = 0.093–0.917, p = 0.035) were associated with decreased death risk. Conclusion: During the third and fourth waves of the pandemic, COVID-19 vaccination was associated with a 57% reduction in lethality among patients in four public hospitals in Venezuela. Key summary points: Less than half (48.6%) of the patients were vaccinated against SARS-CoV-2. At least one out of four patients died during the study period, mainly in the unvaccinated group. Advanced age was associated with a higher risk of death. Vaccination against COVID-19, high oxygen, and enoxaparin administration were factors associated with a lower risk of death.

Background: The opioid crisis caused a huge health concern in the United States. Despite this, few studies have examined the influence of opioid-related disorders (OD) on outcomes after bariatric surgery. The major goal of this study is to determine the impact of OD on in-hospital outcomes for patients undergoing bariatric surgery. Method: The National Inpatient Sample (NIS) database from 2016 to 2020 was used to evaluate patients with OD who underwent bariatric operations including sleeve gastrectomy, Roux-en-Y gastric bypass, and biliopancreatic diversion with duodenal switch. The non-OD comparison group was created using a propensity score match (1:1). Weighted analysis was carried out utilizing NIS-provided weights. The odds ratios were obtained using multivariate logistic regression. Results: A total of 159,455 patients who underwent bariatric surgery were evaluated. Propensity score matching and weighted analysis were used to compare 11,025 in the OD group and 11,025 in the non-OD group. OD was an independent predictor for postoperative complications (odds ratio: 1.29, 95% confidence interval: 1.19–1.39, p < 0.001). Among complications, OD was a predictor for bleeding complications, postoperative nausea and vomiting, anastomotic leak, and mechanical ventilation. In addition, the OD group experienced significantly longer lengths of stay (LOS) and a higher total hospital charges. Conclusion: In patients undergoing bariatric surgery, OD is associated with a significantly higher risk of postoperative complications, as well as increased LOS and total hospital charges. These patients may benefit from further preoperative optimization, including decreasing the opioid dose and closer postoperative monitoring. [ABSTRACT FROM AUTHOR]

BACKGROUND: High-flow tracheal oxygen (HFTO) is being used as supportive therapy during weaning in tracheostomized patients difficult to wean from invasive mechanical ventilation. There is, however, no clinical evidence for such a strategy. Therefore, we conducted a systematic review to summarize studies evaluating the physiologic effects of HFTO during tracheostomy-facilitated weaning and to identify potential areas for future research in this field. METHODS: Observational and interventional studies on critically ill subjects weaning from mechanical ventilation via tracheostomy published until December 22, 2022, were eligible. Studies on high-flow oxygen, only in children, non-human models or animals, on clinical outcome only, abstracts without full-text availability, case reports, and reviews were excluded. Main outcomes were end-expiratory lung volume (EELV) and tidal volume using electrical impedance tomography, respiratory effort assessed by esophageal manometry, work of breathing and neuroventilatory drive as assessed by electrical activity of the diaphragm (EAdi) signal, airway pressure (Paw), oxygenation (... or ...), breathing frequency, tidal volume, and .... RESULTS: In total, 1,327 references were identified, of which 5 were included. In all studies, HFTO was administered with flow 50 L/min and compared to conventional O2 therapy in a crossover design. The total average duration of invasive ventilation at time of measurements ranged from 11-27 d. In two studies, ... and mean Paw were higher with HFTO. EELV, tidal volumes, esophageal pressure swings, and EAdi were similar during high-flow tracheal oxygen and conventional O2 therapy. CONCLUSIONS: The main physiological effect of HFTO as compared to conventional O2 therapy in tracheostomized subjects weaning from mechanical ventilation was improved oxygenation that is probably flow-dependent. Respiratory effort, lung aeration, neuroventilatory drive, and ventilation were similar for HFTO and conventional O2 therapy. Future studies on HFTO should be performed early in the weaning process and should evaluate its effect on sputum clearance and patient-centered outcomes like dyspnea. [ABSTRACT FROM AUTHOR]

BACKGROUND: Recovery of walking independence in critically ill patients is required for safe discharge home. However, the pre-admission predictors affecting this outcome in this patient group are unknown. This study aimed to identify these predictors. METHODS: We included subjects who required mechanical ventilation for at least 48 h and could walk before admission. We investigated frailty, cognitive impairment, and malnutrition risk according to the pre-admission health status. Walking independence was defined as the ability to walk for at least 45 m on level ground. The primary outcome was the association between the time to event from an ICU discharge to walking independence, and pre-admission predictors were analyzed using a Fine-Gray proportional hazards regression. RESULTS: The rate of walking independence was 38.0 (100 cases/person-month; sample N = 144). In the proportional hazards regression model, adjusted for covariates, frailty (hazard ratio [HR] 0.08 [95% CI 0.01-0.67]), pre-frailty (HR 0.37 [95% CI 0.14-0.99]), cognitive impairment (HR 0.21 [95% CI 0.05-0.90]), and malnutrition risk (HR 0.20 [95% CI 0.07-0.58]) were associated with walking independence. CONCLUSIONS: Pre-admission frailty or pre-frailty, cognitive impairment, and malnutrition risk can help predict walking independence in critically ill patients who require mechanical ventilation.

BACKGROUND: Prone positioning (PP) has demonstrated its potential for improving outcomes in patients with ARDS who require invasive mechanical ventilation. However, the ability of prolonged proning to reduce mortality in patients with COVID-19 specifically, sessions lasting > 24 h remains uncertain. METHODS: In this retrospective cohort study, we examined 158 subjects with COVID-19 pneumonia who required mechanical ventilation due to moderate-to-severe ARDS. Seventy-six subjects were placed in standard PP and 82 in extended PP, defined as prone sessions lasting at least 32 h. Our primary aim was to evaluate the effect of EPP on 90-d survival in subjects with COVID-19 with acute severe respiratory failure. To ensure the reliability of our findings and to minimize bias, we applied 3 adjustment approaches: cardinality matching (CM), matching weighting (MW), and inverse probability of treatment weighting with stabilized and trimmed weights (SW). We used Kaplan-Meier curves and Cox proportional hazard models to analyze the effects of EPP on 90-d mortality and sensitivity analysis by calculating E-values. RESULTS: The overall crude 90-d mortality rate was 31.7%. The unadjusted 90-d mortality rates were 19.5% in the EPP group and 44.7% in the SPP group (hazard ratio [HR] 0.35 [95% CI 0.19- 0.63], P < .001). After adjustment for confounding factors using CM, MW, and SW, baseline covariates were balanced between the 2 groups. Subjects in the EPP group exhibited lower 90-d mortality rates after adjustment using CM (HR 0.42 [95% CI 0.23-0.79], P = .007), MW (HR 0.45 [95% CI 0.21-0.95], P = .036), or SW (HR 0.29 [95% CI 0.15-0.56], P < .001). CONCLUSIONS: Extended PP was associated with improved 90-d survival in subjects with COVID-19 undergoing mechanical ventilation for severe ARDS. These findings suggest the potential benefit of EPP in the management of COVID-19-related respiratory failure. Further research and prospective studies are warranted to confirm and elucidate the underlying mechanisms of this association. [ABSTRACT FROM AUTHOR]

Caring for patients in the intensive care unit (ICU) creates competing priorities of interventions for nurses and other health care providers. Oral care might be prioritized lower; however, its neglect may lead to sequelae such as extended time in the ICU, nosocomial diseases most notably ventilator-associated pneumonia (VAP), or oral problems. Safe patient care depends on effective and efficient oral care. The aim of this study was to lower the incidence of VAP and maintain oral health through implementing an “oral care bundle” for mechanically ventilated (MV) patients. Using a quasi-experimental design, we divided 82 adult MV patients in the ICUs of a university-based hospital in Egypt into a control group (n = 41) that received the standard of care and a bundle group (n = 41) that received an “oral care bundle.” The results of the study reported a significantly lower incidence of VAP in the intervention group (P = .015). It can be concluded that there is a significant relationship between receiving an oral care bundle and improved oral health and a reduction in the VAP rate among MV patients. This highlights the need to incorporate the oral care bundle in the daily nursing care for MV patients. [ABSTRACT FROM AUTHOR]

Purpose: To investigate effectiveness of the ABCDEF bundle to manage and prevent delirium. Background: ICU delirium is a common hospital problem that 80% of critically ill patients in the ICU experience. The ABCDEF bundle is one of the tools that included in Delirium guidelines to manage critically ill patients. Research design: Pre- and post intervention a quasiexperimental design was utilized in the present study. Setting: This study was conducted in the intensive care units of Assiut University Hospital. Methods: A total of 60 mechanically ventilated patients were recruited using inclusion and exclusion criteria. The ABCDEF bundle was implemented every day for the first 7 days of ICU admission, and patient sedation and delirium status were assessed using the Confusion Assessment Method for the Intensive Care Unit (CAMICU). Sedation instrument measures were utilized in data collection. Results: Significant differences were found in the incidence of delirium: 20% in the study group versus 70% in the control group. The increased mean of days without delirium ICU stay was 4.6333 in the study group and 1.1000 in the control group, with P value = .001. Conclusion: The mechanically ventilated patients exposed to the implementation of the ABCDE bundle experienced fewer delirium signs than before the ABCDE bundle was implemented.

Objective: This study aimed to assess the effect of mechanical ventilation based on predicted body weight (PBW) and driving pressure (DP) as directed in patients without acute respiratory distress syndrome (ARDS). Design: Experimental, single-blind design with pretest-posttest control group design to assess the effect of using PBW and DP as a guide in regulating the amount of tidal volume and airway pressure in mechanically ventilated patients without ARDS. Setting: We conducted this study in the Intensive Care Unit (ICU) at Dr. Wahidin Sudirohusodo General Hospital, Makassar, from November 2023 to March 2024. Patients and participants: Patients with respiratory failure who were admitted to the ICU of Dr. Wahidin Sudirohusodo General Hospital, Makassar. Intervention: Patients in the PBW group were given a tidal volume setting of 8 ml/kg PBW, adjusted to the lowest positive end-expiratory pressure (PEEP) with the largest lung compliance target, while the DP group did the same thing and adjusted the tidal volume regarding the driving pressure target. The oxygen partial pressure (pO2), carbon dioxide partial pressure (pCO2), oxygen partial pressure to fractional inspired oxygen ratio (P/F ratio), mechanical power, and ventilatory ratio were assessed at the first hour and 24th hour. Measurement and results: Thirty-two patients were divided into two groups, 16 patients each, recruited from November 2023 to March 2024. There was a significant difference in the P/F ratio in the DP group compared to the PBW group after 24 hours (p<0.001 vs p=0.190). Similarly, pCO2 after 24 hours significantly differed between the DP group (p=0.001) and the PBW group (p=0.658). Regarding mechanical power, the two groups had no significant difference (10.92±2.51 vs 11.68±1.21 Joules/min, p=0.284). The PBW group had a wider range of mechanical power values (range 8.4 J/min) than the DP group (range 4.6 J/min), suggesting the DP group had more consistent mechanical power magnitude. Conclusion: Mechanical ventilation guided by DP can improve oxygenation and ventilation outcomes. Even though both the PBW and DP methods resulted in similar mechanical power levels, the DP-guided approach provided more stable and predictable mechanical power values. This stability can benefit patient management in the ICU, as it suggests a reduced risk of lung injury and potentially better overall outcomes for patients receiving mechanical ventilation.

Background: Hospital-acquired pressure ulcer (HAPU) is a significant problem in healthcare settings and is associated with negative impacts on patient health. Although monitoring of pressure ulcers (PUs) among hospitalised patients was started more than a decade ago in Oman, no previous studies have been completed to estimate the prevalence and risk factors of HAPUs among patients in the intensive care unit (ICU). The aim of this study was to estimate the prevalence and identify risk factors for HAPUs among adult ICU patients in selected tertiary hospitals in Oman. Method: A retrospective, cross-sectional, nested, case–control design was used to identify the prevalence rate of HAPUs and risk factors for a cohort of adult ICU patients over one calendar year (1 January–31 December 2019) in two tertiary hospitals in Oman. Results: The prevalence rate for HAPU among ICU patients in Oman was 36.4%. However, when excluding cases of stage 1 ulcer, the rate was 30.37%. The most prevalent location was the sacrum (64.1%), and the most common stage was stage 2 (73.1%). The risk factors for HAPU included male sex (odds ratio (OR): 0.37; p=0.023), organ failure (OR: 3.2; p=0.033), cancer (OR: 3.41; p=0.049), cerebrovascular accident (OR: 12.33; p=0.001), mechanical ventilator (OR: 9.64; p=0.025) and ICU length of stay (OR: 1.24; p<0.001). Conclusion: HAPUs among ICU patients constitute a significant problem associated with severe clinical consequences and result in substantial adverse healthcare outcomes worldwide, including in Oman. Identifying the risk factors and the impact on the healthcare system is the foundation for preventing and managing HAPUs. [ABSTRACT FROM AUTHOR]

Purpose: To measure the prevalence of speech-language pathologist (SLP) involvement and associated trends for critically ill children in United States (US) paediatric intensive care units (PICU) through secondary analysis of the Prevalence of Acute Rehab for Kids in the PICU (PARK-PICU) study data. Method: A secondary analysis of cross-sectional point prevalence study conducted over 1 day in 82 US PICUs. Data collected included SLP presence, patients' age, length of stay, medical interventions, aetiology, admission data, Glasgow Coma Scale scores, staffing involvement, and family presence. Result: Among 961 patients, 82 were visited by an SLP on the study day for a prevalence of 8.5%. Most visits were for children <3 years old. The odds of SLP involvement were lower for children who were 7–12 years old (vs. age 0–2; adjusted odds ratio [aOR] 0.28; 95% CI 0.1–0.8), were mechanically ventilated via endotracheal tube (vs. room air; aOR 0.02; 95% CI 0.005–0.11), or had mild or severe disability (mild vs. no disability; aOR 0.34; 95% CI 0.16–0.76 and severe vs. no disability; aOR 0.39; 95% CI 0.17–0.90). Concurrent physical and/or occupational therapy involvement was associated with higher odds of SLP involvement (aOR 3.6; 95% CI 2.1–6.4). Conclusion: SLP involvement is infrequent in US PICUs. PICU teams should be educated about the scope of SLP practice, to support communication and oral feeding needs during early recovery from critical illness. [ABSTRACT FROM AUTHOR]

Sepsis is a dysregulated immune response to an infection that leads to organ dysfunction. Sepsis-associated organ dysfunction involves multiple inflammatory mechanisms and complex metabolic reprogramming of cellular function. These mechanisms cooperate through multiple organs and systems according to a complex set of long-distance communications mediated by cellular pathways, solutes, and neurohormonal actions. In sepsis, the concept of organ crosstalk involves the dysregulation of one system, which triggers compensatory mechanisms in other systems that can induce further damage. Despite the abundance of studies published on ​​organ crosstalk in the last decade, there is a need to formulate a more comprehensive framework involving all organs to create a more detailed picture of sepsis. In this paper, we review the literature published on organ crosstalk in the last 10 years and explore how these relationships affect the progression of organ failure in patients with septic shock. We explored these relationships in terms of the heart–kidney–lung, gut-microbiome–liver–brain, and adipose tissue–muscle–bone crosstalk in sepsis patients. A deep connection exists among these organs based on crosstalk. We also review how multiple therapeutic interventions administered in intensive care units, such as mechanical ventilation, antibiotics, anesthesia, nutrition, and proton pump inhibitors, affect these systems and must be carefully considered when managing septic patients. The progression to multiple organ dysfunction syndrome in sepsis patients is still one of the most frequent causes of death in critically ill patients. A better understanding and monitoring of the mechanics of organ crosstalk will enable the anticipation of organ damage and the development of individualized therapeutic strategies.

Background: Opioid-reduced multimodal analgesia has been used clinically for many years to decrease the perioperative complications associated with opioid drugs. We aimed to assess the clinical effects of opioid-reduced anesthesia during thoracoscopic sympathectomy. Methods: Surgical patients (n = 151) with palmar hyperhidrosis were randomly divided into control (Group C, 73 patients) and test (Group T, 78 patients) groups. All patients were administered general anesthesia using a laryngeal mask. In Group C, patients received propofol, fentanyl, and cisatracurium for anesthesia induction, and maintenance was achieved with propofol and remifentanil, along with mechanical ventilation during the operation. In Group T, anesthesia was induced with propofol, dezocine, and dexmedetomidine (DEX) and maintained with propofol, DEX, and an intercostal nerve block, along with spontaneous breathing throughout the operation. Perioperative complications related to opioid use include hypotension, bradycardia, hypertension, tachycardia, hypoxemia, nausea, vomiting, urine retention, itching, and dizziness were observed. To assess the impact of these complications, we recorded and compared vital signs, blood gas indices, visual analogue scale (VAS) scores, adverse events, and patient satisfaction between the two groups. Results: Perioperative complications related to opioid use were similar between groups. There were no significant differences in the type of perioperative sedation, analgesia index, respiratory and circulatory indicators, blood gas analysis, postoperative VAS scores, adverse reactions, propofol dosage, postoperative recovery time, and patient satisfaction. Conclusions: In minimally invasive surgeries such as thoracoscopic sympathectomy, opioid-reduced anesthesia was found to be safe and effective; however, this method did not demonstrate clinical advantages.

Background: Previous retrospective research has shown that maintaining prone positioning (PP) for an average of 40 h is associated with an increase of survival rates in intubated patients with COVID-19-related acute respiratory distress syndrome (ARDS). This study aims to determine whether a cumulative PP duration of more than 32 h during the first 2 days of intensive care unit (ICU) admission is associated with increased survival compared to a cumulative PP duration of 32 h or less. Methods: This study is an ancillary analysis from a previous large international observational study involving intubated patients placed in PP in the first 48 h of ICU admission in 149 ICUs across France, Belgium and Switzerland. Given that PP is recommended for a 16-h daily duration, intensive PP was defined as a cumulated duration of more than 32 h during the first 48 h, whereas standard PP was defined as a duration equal to or less than 32 h. Patients were followed-up for 90 days. The primary outcome was mortality at day 60. An Inverse Probability Censoring Weighting (IPCW) Cox model including a target emulation trial method was used to analyze the data. Results: Out of 2137 intubated patients, 753 were placed in PP during the first 48 h of ICU admission. The intensive PP group (n = 79) had a median PP duration of 36 h, while standard PP group (n = 674) had a median of 16 h during the first 48 h. Sixty-day mortality rate in the intensive PP group was 39.2% compared to 38.7% in the standard PP group (p = 0.93). Twenty-eight-day and 90-day mortality as well as the ventilator-free days until day 28 were similar in both groups. After IPCW, there was no significant difference in mortality at day 60 between the two-study groups (HR 0.95 [0.52–1.74], p = 0.87 and HR 1.1 [0.77–1.57], p = 0.61 in complete case analysis or in multiple imputation analysis, respectively). Conclusions: This secondary analysis of a large multicenter European cohort of intubated patients with ARDS due to COVID-19 found that intensive PP during the first 48 h did not provide a survival benefit compared to standard PP.

Due to an ageing population and prolonged lifespan, pressure injury (PI) incidence is increasing. Patients with a PI typically endure longer hospital stays, which create a significant burden on healthcare resources and costs. With appropriate preventive interventions, most PIs can be avoided; however, skin failure may become inevitable in particular instances. These are classified as unavoidable PIs. Patients in a critical condition are exposed to a unique set of therapies, medications and bodily states. Oftentimes, these instances decrease tissue tolerance, which may promote PI formation. Patients who are critically ill, especially those with extended stays in the intensive care unit, are susceptible to skin failure due to: prolonged immobility; mechanical ventilation; acute respiratory distress syndrome; COVID-19; sepsis; multiorgan system dysfunction; vasopressor use; and treatment with extracorporeal membrane oxygenation. Poor perfusion leading to skin breakdown results from the compounding factors of circulatory collapse, build-up of metabolites, compromised lymphatic drainage, patient comorbidities, and ischaemia via capillary blockage in patients who are critically ill. In addition, similar physiology is present during end-of-life multisystem organ failure, which creates unavoidable skin deterioration. The aim of this review is to provide an overview of circumstances which decrease tissue tolerance and ultimately lead to PI development, despite adequate preventive measures in patients who are critically ill.

Purpose: Communication with nonspeaking patients is a critical challenge of person-centered care. This scoping review aimed to map the literature on augmentative and alternative communication (AAC) interventions for nonspeaking mechanically ventilated and tracheostomy patients in critical and acute care settings. Method: Electronic database, ancestry, and forward citation searches were conducted using eligibility criteria established a priori. Data were extracted, synthesized, and summarized according to scoping review methodology. Studies were categorized by type of intervention and summarized in terms of purpose, participants, design, quality appraisal (including validity and reliability of selected efficacy measures), and efficacy. Results: Small-to-large treatment effect sizes indicated demonstrable impact on patient health and communication efficacy with high-tech and no-tech visual interface-based interventions and systematic nurse training interventions. Treatment effects primarily pertained to dependent variables of patient anxiety, communication satisfaction, comfort, symptom self-reporting, and nursing practice changes. Conclusions: There is a paucity of high-quality AAC intervention research for mechanically ventilated and tracheostomy patients in critical and acute care settings. Emergent evidence suggests that select visual interface and nurse training interventions can impact efficacy of patient-provider communication and patients' overall health. [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]

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]

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: 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: 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]

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: 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]

Objective: Ventilator‐assisted preoxygenation (VAPOX) is a method of preoxygenation and apnoeic ventilation which has been tried in hospital setting. We aimed to describe VAPOX during intubation of critically unwell patients in aeromedical retrieval setting. Methods: Retrospective observational study of VAPOX performed at LifeFlight Retrieval Medicine (LRM) between January 2018 and December 2022 across Queensland, Australia. Demographic and clinical data were recorded. Descriptive statistics and paired Student's t‐tests were used to evaluate the efficacy of VAPOX on oxygen saturation (SpO2). Results: VAPOX was used in 40 patients. Diagnoses included pneumonia (n = 11), COPD (n = 6) and neurological (n = 7). Patients were intubated in hospital (n = 36), in helicopter (n = 2) and ambulance (n = 2). Median VAPOX settings were: positive end‐expiratory pressure 6 (IQR 5–9), pressure support 10 (IQR 10–14) and back up respiratory rate 14 (IQR 11–18). Twelve agitated patients underwent delayed sequence induction with ketamine. There was a statistically significant increase in SpO2 after application of VAPOX (P < 0.001), followed by a slight decrease after intubation (P = 0.006). Mean SpO2 were significantly improved after intubation compared with on arrival of LRM (P = 0.016). Hypotension was present prior to VAPOX (n = 13), during VAPOX (n = 2) and post‐intubation (n = 15). Two patients had cardiac arrest. Three patients were started on VAPOX but subsequently failed. There were no significant oxygen depletion or aspiration events. Conclusion: VAPOX can be considered for pre‐intubation optimisation in the retrieval environment. The incidence of post‐intubation critical hypoxia was low, and hypotension was high. Pre‐intubation respiratory physiology can be optimised by delivering variable pressure supported minute ventilation, achieving a low incidence of critical hypoxia. [ABSTRACT FROM AUTHOR]

Introduction and aims: This study examined critical care nurses', physicians', and allied health professionals' perceptions of factors that support, inhibit, or limit the use of sedation interruption (SI) to improve the use of this integral component of care for mechanically ventilated patients. Method: We conducted a theory-based, descriptive qualitative study using semi-structured interviews with critical care registered nurses, respiratory therapists, a pharmacist, and a physician in a hospital in Ontario, Canada. The interview guide and analysis were informed by the Theoretical Domains Framework and transcripts were analyzed using content analysis. Results: Weidentified 9 facilitators and 20 barriers to SI use by nurses. Facilitators included the innovation (importance of protocols) and potential adopters (comfort with the skill). The barriers were the potential adopters' (nurses) knowledge gaps regarding the performance and goal of SI and the practice environment (lack of time, availability of extra staff, and lack of multidisciplinary rounds). Conclusion: This study identified facilitators and barriers to SI for mechanically ventilated patients. Implementation efforts must address barriers associated with nurses, the environment, and contextual factors. A team-based approach is essential, as the absence of interprofessional rounds is a significant barrier to the appropriate use or non-use of SI. Future research can focus on the indications, contraindications, and goals of SI, emphasizing a shared appreciation for these factors across disciplines. Nursing capacity to manage a patient waking up from sedation is necessary for point-of-care adherence; future research should focus on the best ways to do so. Implementation study designs should use theory and evidence-based determinants of SI to bridge the evidence-to-practice gap. [ABSTRACT FROM AUTHOR]

Background: Few randomized controlled trials have evaluated the use of ketamine vs opiate-based analgosedation. Methods: A retrospective cohort analysis of 169 mechanically ventilated patients admitted to the medical intensive care unit (MICU) at an academic medical center was conducted to evaluate efficacy of ketamine vs opiate-based analgosedation by comparing the percentage of time within target sedation range. The primary outcome was percentage of time within target sedation range (RASS -1 to +1) within first 72 hours of primary sedation initiation. Secondary outcomes including percentage of time under-sedated, over-sedated, and in coma; use of concomitant analgesic, sedative, and antipsychotic agents; presence of delirium; percentage of CPOT scores at goal; and hemodynamic effects were also evaluated. Results: After weighting, the mean percentage of time at RASS goal for ketamine patients was 43.0% compared to 41.4% for opiate-based sedation patients. Ketamine was not significantly non-inferior to opiate-based sedation for the mean percentage of time at RASS goal (P =.11). The median percentage of CPOT scores at goal was 13.3% higher in the ketamine group (P =.042). Patients in the ketamine group received significantly less additional sedative agents than the patients in the opiate-based sedation group. Conclusion: A similar percent of time at RASS goal was found for the ketamine analgosedation group compared to the opiate-based sedation group, although this did not reach statistical signicance for non-inferiority due to lack of statistical power. This study found a higher percentage of CPOT scores within goal with less additional sedative agents required compared to an opiate-based sedation regimen. [ABSTRACT FROM AUTHOR]

Objective: To design, develop and validate a new tool, called NEUMOBACT, to evaluate critical care nurses' knowledge and skills in ventilator‐associated pneumonia (VAP) and catheter‐related bacteraemia (CRB) prevention through simulation scenarios involving central venous catheter (CVC), endotracheal suctioning (ETS) and mechanically ventilated patient care (PC) stations. Background: Simulation‐based training is an excellent way for nurses to learn prevention measures in VAP and CRB. Design: Descriptive metric study to develop NEUMOBACT and analyse its content and face validity that followed the COSMIN Study Design checklist for patient‐reported outcome measurement instruments. Methods: The first version was developed with the content of training modules in use at the time (NEUMOBACT‐1). Delphi rounds were used to assess item relevance with experts in VAP and CRB prevention measures, resulting in NEUMOBACT‐2. Experts in simulation methods then assessed feasibility, resulting in NEUMOBACT‐3. Finally, a pilot test was conducted among 30 intensive care unit (ICU) nurses to assess the applicability of the evaluation tool in clinical practice. Results: Seven national experts in VAP and CRB prevention and seven national simulation experts participated in the analysis to assess the relevance and feasibility of each item, respectively. After two Delphi rounds with infection experts, four Delphi rounds with simulation experts, and pilot testing with 30 ICU nurses, the NEUMOBACT‐FINAL tool consisted of 17, 26 and 21 items, respectively, for CVC, ETS and PC. Conclusion: NEUMOBACT‐FINAL is useful and valid for assessing ICU nurses' knowledge and skills in VAP and CRB prevention, acquired through simulation. Relevance for Clinical Practice: Our validated and clinically tested tool could facilitate the transfer of ICU nurses' knowledge and skills learning in VAP and CRB prevention to critically ill patients, decreasing infection rates and, therefore, improving patient safety. Patient or Public Contribution: Experts participated in the Delphi rounds and nurses in the pilot test. [ABSTRACT FROM AUTHOR]

Given the important role of patient-ventilator assessments in ensuring the safety and efficacy of mechanical ventilation, a team of respiratory therapists and a librarian used Grading of Recommendations, Assessment, Development, and Evaluation methodology to make the following recommendations: (1) We recommend assessment of plateau pressure to ensure lung-protective ventilator settings (strong recommendation, high certainty); (2) We recommend an assessment of tidal volume (VT) to ensure lung-protective ventilation (4-8 mL/kg/predicted body weight) (strong recommendation, high certainty); (3) We recommend documenting VT as mL/kg predicted body weight (strong recommendation, high certainty); (4) We recommend an assessment of PEEP and auto-PEEP (strong recommendation, high certainty); (5) We suggest assessing driving pressure to prevent ventilator-induced injury (conditional recommendation, low certainty); (6) We suggest assessing FIO2 to ensure normoxemia (conditional recommendation, very low certainty); (7) We suggest telemonitoring to supplement direct bedside assessment in settings with limited resources (conditional recommendation, low certainty); (8) We suggest direct bedside assessment rather than telemonitoring when resources are adequate (conditional recommendation, low certainty); (9) We suggest assessing adequate humidification for patients receiving noninvasive ventilation (NIV) and invasive mechanical ventilation (conditional recommendation, very low certainty); (10) We suggest assessing the appropriateness of the humidification device during NIV and invasive mechanical ventilation (conditional recommendation, low certainty); (11) We recommend that the skin surrounding artificial airways and NIV interfaces be assessed (strong recommendation, high certainty); (12) We suggest assessing the dressing used for tracheostomy tubes and NIV interfaces (conditional recommendation, low certainty); (13) We recommend assessing the pressure inside the cuff of artificial airways using a manometer (strong recommendation, high certainty); (14) We recommend that continuous cuff pressure assessment should not be implemented to decrease the risk of ventilator-associated pneumonia (strong recommendation, high certainty); and (15) We suggest assessing the proper placement and securement of artificial airways (conditional recommendation, very low certainty).

BACKGROUND: Noninvasive ventilation (NIV) is a widely used and well-established treatment modality for respiratory failure. In patients with increased respiratory work of breathing, accessory muscles are commonly activated along with the diaphragm. Whereas diaphragm ultrasound has been utilized to assess outcomes of mechanical ventilation, the data on intercostal muscle ultrasound remain limited. We aimed to investigate the association between intercostal muscle thickening fraction (TF) and NIV failure in critical care patients with hypercapnic respiratory failure. METHODS: Critical care subjects receiving NIV for hypercapnic respiratory failure were enrolled in the study. The intercostal muscle TF was measured on admission day (day 0) and the following day (day 1). NIV failure was defined as the need for invasive mechanical ventilation or death during NIV therapy. RESULTS: A total of 158 subjects were enrolled, and 30 experienced NIV failure. Age, sex, and body mass index (BMI) were similar in the NIV success and failure groups. Acute Physiology And Chronic Health Evaluation II (APACHE II) and the Sequential Organ Failure Assessment (SOFA) scores were higher in the NIV failure group. In terms of causes of respiratory failure, the COPD exacerbation rate was higher in the NIV success group. TF was higher in the NIV failure group on both day 0 and day 1. The increased TF on the ICU admission day, with a cutoff value of 12%, was associated with NIV failure after adjusting for age, sex, BMI, APACHE II, and SOFA. Persistence of a higher TF value on both day 0 and day 1 was also associated with NIV failure risk. CONCLUSIONS: There was a positive relation between intercostal muscle TF measured by ultrasound and NIV failure, even after adjusting for APACHE II and SOFA scores. [ABSTRACT FROM AUTHOR]

Background: Whether intensive glucose control reduces mortality in critically ill patients remains uncertain. Patient-level meta-analyses can provide more precise estimates of treatment effects than are currently available. Methods: We pooled individual patient data from randomized trials investigating intensive glucose control in critically ill adults. The primary outcome was in-hospital mortality. Secondary outcomes included survival to 90 days and time to live cessation of treatment with vasopressors or inotropes, mechanical ventilation, and newly commenced renal replacement. Severe hypoglycemia was a safety outcome. Results: Of 38 eligible trials (n=29,537 participants), 20 (n=14,171 participants) provided individual patient data including in-hospital mortality status for 7059 and 7049 participants allocated to intensive and conventional glucose control, respectively. Of these 1930 (27.3%) and 1891 (26.8%) individuals assigned to intensive and conventional control, respectively, died (risk ratio, 1.02; 95% confidence interval [CI], 0.96 to 1.07; P=0.52; moderate certainty). There was no apparent heterogeneity of treatment effect on in-hospital mortality in any examined subgroups. Intensive glucose control increased the risk of severe hypoglycemia (risk ratio, 3.38; 95% CI, 2.99 to 3.83; P<0.0001). Conclusions: Intensive glucose control was not associated with reduced mortality risk but increased the risk of severe hypoglycemia. We did not identify a subgroup of patients in whom intensive glucose control was beneficial.

Background: Mechanical ventilation is a form of life support for 90% of critically ill patients. Aim: To evaluate the effect of cough augmentation techniques on the airway clearance of a mechanically ventilated patient. Subjects and Method: Design: Quasi- experimental study. Setting: This study was conducted at Anesthesia Intensive Care Unit of Tanta Emergency Hospital. Subjects: 60 cases divided into two groups 30 in each in the above previously mentioned setting. Tools: two tools were utilized in this research. Tool I: Mechanically Ventilated Patients Evaluation Sheet, Tool II: Patients' Hemodynamic Parameters Sheet. Results: patients with a specific medical condition have a significant increase in respiratory rate, heart rate, systolic and diastolic blood pressure, and oxygen saturation after 25 minutes of intervention (p<0.05). The study and control groups didn't show significant differences in temperature (p<0.05). Mean pulmonary filtration rate (PH) didn't change significantly, but a significant decrease was observed in the third day only among the study group. Conclusion: The study found that cough augmentation techniques significantly improved airway clearance in mechanically ventilated patients, leading to increased hemodynamic stability, oxygen saturation, blood gas exchange, and breathing stability. Recommendation: The investigation suggests further multi-center studies and the use of cough augmentation techniques in managing secretions complaints in Intensive Care Units. [ABSTRACT FROM AUTHOR]

Objectives: Coronary artery calcifications detected by computed tomography (CT) provide prognostic relevance for vascular disorders and coronary heart disease, whereas their prognostic relevance in severely injured trauma patients remains unclear. Material and Methods: All consecutive trauma patients requiring emergency tracheal intubation before initial CT at a level-1 trauma center and admission to the intensive care unit (ICU) over a 12-year period (2008–2019) were reanalyzed. The Weston score, a semiquantitative method to quantify coronary calcifications, was evaluated as a prognostic variable based upon whole-body trauma CT analysis. Results: Four hundred fifty-eight patients (74.6% male) with a median age of 49 years, median injury severity score of 26 points, 24-h mortality rate of 7.6%, and 30-day mortality rate of 22.1% met the inclusion criteria and were analyzed. Coronary artery calcification was present in 214 patients (46.7%). After adjustment for confounding factors, the Weston score was an independent predictor for 24-h mortality (hazard ratio, HR 1.19, 95% confidence interval, CI 1.06–1.32, p =.002) and 30-day mortality (HR 1.09, 95% CI 1.01–1.17, p =.027). In a subanalysis of 357 survivors, the Weston score was significantly associated with ICU length of stay (LOS) (beta weight 0.89, 95% CI 0.3–1.47, p =.003) but not with mechanical ventilation duration (beta weight 0.05, 95% CI -0.2–0.63, p =.304). Conclusion: CT-detected coronary calcification was a significant prognostic factor for 24-h- and 30-day-mortality in severely injured trauma patients requiring tracheal intubation, and influenced ICU LOS in survivors.

Objective: During the first wave of the COVID-19 (SARS CoV-2) pandemic, patients being treated for acute respiratory distress syndrome were proned while intubated with mechanical ventilation. In this study, we aimed to compare the diet outcomes at the time of acute hospital discharge of patients with COVID-19 who were proned while endotracheally intubated (ETT-proned) with those who were intubated with but not proned (ETT-supine). Design: The design used is a single-center, retrospective, descriptive study. Results: Between March 1, 2020, and August 2020, 193 critically ill adult patients with severe COVID-19 requiring endotracheal intubation with mechanical ventilation were referred for a swallowing evaluation at our acute care tertiary hospital; 114 of these patients were ETT-proned. At the time of discharge from the hospital, there was no significant difference in diet level between ETT-proned and ETT-supine patients. Significant factors associated with restricted diet at discharge included older age (p < .001) and non-English-speaking status (p = .05). Conclusions: In this study, diet levels at the time of discharge did not differ significantly between the patient groups by time of discharge. These results should be interpreted with caution in relation to the clinical swallow evaluation, which was curtailed by practice restrictions imposed by pandemic protocols. Future research should objectively assess swallow function in patients who were proned during intubation with mechanical ventilation, utilizing evidence-based swallow screening protocols, standardized assessment of physiology via imaging (videofluoroscopic swallow studies or flexible endoscopic evaluation of swallowing), and long-term follow-up to directly and objectively determine the impact proning has on swallow physiology.

Background: Therapeutic plasma exchanges (TPE), which affect the humoral response, are often performed in combination with immunosuppressive drugs. For this reason, TPE may be associated with an increased susceptibility to infections. We aimed to describe blood stream infection (BSI) incidence in ICU patients treated with TPE and to identify associated risk factors. Methods: We retrospectively included patients that had received at least one session of TPE in the ICU of one of the 4 participating centers (all in Paris, France) between January 1st 2010 and December 31th 2019. Patients presenting with a BSI during ICU stay were compared to patients without such an infection. Risk factors for BSI were identified by a multivariate logistic regression model. Results: Over 10 years in the 4 ICUs, 387 patients were included, with a median of 5 [2–7] TPE sessions per patient. Most frequent indications for TPE were thrombotic microangiopathy (47%), central nervous system inflammatory disorders (11%), hyperviscosity syndrome (11%) and ANCA associated vasculitis (8.5%). Thirty-one patients (8%) presented with a BSI during their ICU stay, a median of 7 [3–11] days after start of TPE. In a multivariate logistic regression model, diabetes (OR 3.32 [1.21–8.32]) and total number of TPE sessions (OR 1.14 [1.08–1.20]) were independent risk factors for BSI. There was no difference between TPE catheter infection related BSI (n = 11 (35%)) and other sources of BSI (n = 20 (65%)) regarding catheter insertion site (p = 0.458) or rate of TPE catheter related deep vein thrombosis (p = 0.601). ICU course was severe in patients presenting with BSI when compared to patients without BSI, with higher need for mechanical ventilation (45% vs 18%, p = 0.001), renal replacement therapy (42% vs 20%, p = 0.011), vasopressors (32% vs 12%, p = 0.004) and a higher mortality (19% vs 5%, p = 0.010). Conclusion: Blood stream infections are frequent in patients receiving TPE in the ICU, and are associated with a severe ICU course. Vigilant monitoring is crucial particularly for patients receiving a high number of TPE sessions. [ABSTRACT FROM AUTHOR]

Background: The recent global pandemic due to severe acute respiratory syndrome coronavirus-2 resulted in a high rate of multi-organ failure and mortality in a large patient population across the world. As such, a possible correlation between acute kidney injury (AKI) and increased mortality rate in these patients has been suggested in literature. Methods: This is a two-year retrospective study of critically ill adult patients infected with COVID-19 that were admitted to the intensive care unit (ICU) on ventilatory support. Two groups of patients were identified in this study, those who were directly admitted to the ICU or those who were initially admitted to the Medical Floor and were later transferred to the ICU due to either worsening respiratory status or change in their hemodynamic conditions. Within each group, three subgroups were created based on the status of AKI, namely, those who did not develop AKI, those who developed AKI, and those who with previous history of dialysis dependent AKI. Results: The AKI subgroup had the highest mortality rate in the ICU and Floor patients. Of note, those patients who were directly admitted to the Floor and were later transferred to the ICU for worsening conditions also experienced a higher mortality rate if they had developed AKI during their course of hospital stay. Conclusions: This study identified a statistically significant higher mortality in patients who developed AKI than those who did not develop AKI among critically ill patients. Trial registration: Clinicaltrials.gov registration number NCT05964088. Date of registration: July 24 2023. [ABSTRACT FROM AUTHOR]

Objective: To investigate the relationship between central venous pressure (CVP) and acute right ventricular (RV) dysfunction in critically ill patients on mechanical ventilation. Methods: This retrospective study enrolled mechanically ventilated critically ill who underwent transthoracic echocardiographic examination and CVP monitoring. Echocardiographic indices including tricuspid annular plane systolic excursion (TAPSE), fractional area change (FAC), and tricuspid lateral annular systolic velocity wave (S') were collected to assess RV function. Patients were then classified into three groups based on their RV function and presence of systemic venous congestion as assessed by inferior vena cava diameter (IVCD) and hepatic vein (HV) Doppler: normal RV function (TAPSE ≥ 17 mm, FAC ≥ 35% and S' ≥9.5 cm/sec), isolated RV dysfunction (TAPSE < 17 mm or FAC < 35% or S' <9.5 cm/sec with IVCD ≤ 20 mm or HV S ≥ D), and RV dysfunction with congestion (TAPSE < 17 mm or FAC < 35% or S' <9.5 cm/sec with IVCD > 20 mm and HV S < D). Results: A total of 518 patients were enrolled in the study, of whom 301 were categorized in normal RV function group, 164 in isolated RV dysfunction group and 53 in RV dysfunction with congestion group. Receiver operating characteristic analysis revealed a good discriminative ability of CVP for identifying patients with RV dysfunction and congestion(AUC 0.839; 95% CI: 0.795–0.883; p < 0.001). The optimal CVP cutoff was 10 mm Hg, with sensitivity of 79.2%, specificity of 69.4%, negative predictive value of 96.7%, and positive predictive value of 22.8%. A large gray zone existed between 9 mm Hg and 12 mm Hg, encompassing 95 patients (18.3%). For identifying all patients with RV dysfunction, CVP demonstrated a lower discriminative ability (AUC 0.616; 95% CI: 0.567–0.665; p < 0.001). Additionally, the gray zone was even larger, ranging from 5 mm Hg to 12 mm Hg, and included 349 patients (67.4%). Conclusions: CVP may be a helpful indicator of acute RV dysfunction patients with systemic venous congestion in mechanically ventilated critically ill, but its accuracy is limited. A CVP less than10 mm Hg can almost rule out RV dysfunction with congestion. In contrast, CVP should not be used to identify general RV dysfunction. [ABSTRACT FROM AUTHOR]

Objective Dexamethasone has been associated with early extubation and shorter duration of mechanical ventilation in preterm infants. High doses or prolonged courses of dexamethasone may be associated with poor neurodevelopmental outcomes. Study Design This is an observational cohort study assessing the efficacy of a low-dose short dexamethasone course combined with postextubation bubble continuous positive airway pressure (bCPAP) strategy on rates of successful extubation and reduction of the duration of invasive mechanical ventilation in extremely preterm infants. We compared the short-term outcomes of implementing such strategy on a group of infants with birth weight <750 g to a historical cohort. Results Among infants intubated for at least 10 days, median time to extubation from starting the dexamethasone course was 2 days (interquartile range: 1–3). Total duration of intubation was significantly shorter in infants who received dexamethasone compared with the control groups (21 ± 6 vs. 30 ± 10 days, p = 0.03), and although statistically nonsignificant, duration to wean to 21% bCPAP was shorter compared with the control group (48 ± 13 vs. 74 ± 29 days, p = 0.06). Conclusion A low-dose short dexamethasone course combined with postextubation bCPAP intervention may be associated with successful early extubation and shorter duration of mechanical ventilation. Key Points Noninvasive strategies may not succeed in infants < 750 g birth weight. Bubble CPAP has been shown to be associated with reduced complications including chronic lung disease. Postnatal dexamethasone therapy may succeed in conjunction with bubble CPAP to reduce reintubation. [ABSTRACT FROM AUTHOR]

Objective: The objective of this study is to explore the experiences of patients who received mechanical ventilation (MV) support during their intensive care unit (ICU) stay in Jordan. Methods: A phenomenological hermeneutic approach was conducted, informed by the philosophy of Martin Heidegger. Fifteen patients participated in interviews regarding their experiences during their time in the critical care unit of three public hospitals in Jordan. Interpretive Phenomenological Analysis (IPA) was used to analyse the data. Findings: The findings of the current study indicated that patients who received MV support during their ICU stays experienced both physical and psychological suffering. A pattern of shared experiences among intensive care patients was identified. Five main themes captured the patients' experiences: (1) feeling powerless, (2) being unable to recognise time, (3) feeling dead, (4) experiencing physical pain, and (5) having future concerns. Conclusion: The current study found that mechanically ventilated ICU patients suffer both physically and psychologically. Nurses should use specific strategies to relieve discomfort in addition to pain treatment. This is especially essential for non-verbal patients, whose actions may resemble those of their clinicians in pain. [ABSTRACT FROM AUTHOR]

Purpose: We aimed to evaluate the ability of the peripheral perfusion index (PPI) to predict reintubation of critically ill surgical patients. Methods: This prospective observational study included mechanically ventilated adults who were extubated after a successful spontaneous breathing trial (SBT). The patients were followed up for the next 48 h for the need for reintubation. The heart rate, systolic blood pressure, respiratory rate, peripheral arterial oxygen saturation (SpO2), and PPI were measured before-, at the end of SBT, 1 and 2 h postextubation. The primary outcome was the ability of PPI 1 h postextubation to predict reintubation using area under the receiver operating characteristic curve (AUC) analysis. Univariate and multivariate analyses were performed to identify predictors for reintubation. Results: Data from 62 patients were analysed. Reintubation occurred in 12/62 (19%) of the patients. Reintubated patients had higher heart rate and respiratory rate; and lower SpO2 and PPI than successfully weaned patients. The AUC (95%confidence interval) for the ability of PPI at 1 h postextubation to predict reintubation was 0.82 (0.71–0.91) with a negative predictive value of 97%, at a cutoff value of ≤ 2.5. Low PPI and high respiratory rate were the independent predictors for reintubation. Conclusion: PPI early after extubation is a useful tool for prediction of reintubation. Low PPI is an independent risk factor for reintubation. A PPI > 2.5, one hour after extubation can confirm successful extubation. [ABSTRACT FROM AUTHOR]

Infusion of fluids is one of the most common medical acts when resuscitating critically ill patients. However, fluids most often are given without consideration of how fluid infusion can actually improve tissue perfusion. Arthur Guyton's analysis of the circulation was based on how cardiac output is determined by the interaction of the factors determining the return of blood to the heart, i.e. venous return, and the factors that determine the output from the heart, i.e. pump function. His theoretical approach can be used to understand what fluids can and cannot do. In his graphical analysis, right atrial pressure (RAP) is at the center of this interaction and thus indicates the status of these two functions. Accordingly, trends in RAP and cardiac output (or a surrogate of cardiac output) can provide important guides for the cause of a hemodynamic deterioration, the potential role of fluids, the limits of their use, and when the fluid is given, the response to therapeutic interventions. Use of the trends in these values provide a physiologically grounded approach to clinical fluid management. [ABSTRACT FROM AUTHOR]

Background: During the first COVID-19 pandemic wave, COVID-19-associated pulmonary aspergillosis (CAPA) has been reported in up to 11–28% of critically ill COVID-19 patients and associated with increased mortality. As new SARS-CoV-2 variants emerged, the characteristics of critically ill COVID-19 patients have evolved, particularly in the era of Omicron. The purpose of this study is to investigate the characteristics of CAPA in the era of new variants. Methods: This is a prospective multicenter observational cohort study conducted in France in 36 participating intensive care units (ICU), between December 7th, 2021 and April 26th 2023. Diagnosis criteria of CAPA relied on European Confederation of Medical Mycology (ECMM)/International Society for Human & Animal Mycology (ISHAM) consensus criteria. Results: 566 patients were included over the study period. The prevalence of CAPA was 5.1% [95% CI 3.4–7.3], and rose to 9.1% among patients who required invasive mechanical ventilation (IMV). Univariable analysis showed that CAPA patients were more frequently immunosuppressed and required more frequently IMV support, vasopressors and renal replacement therapy during ICU stay than non-CAPA patients. SAPS II score at ICU admission, immunosuppression, and a SARS-CoV-2 Delta variant were independently associated with CAPA in multivariable logistic regression analysis. Although CAPA was not significantly associated with day-28 mortality, patients with CAPA experienced a longer duration of mechanical ventilation and ICU stay. Conclusion: This study contributes valuable insights into the prevalence, characteristics, and outcomes of CAPA in the era of Delta and Omicron variants. We report a lower prevalence of CAPA (5.1%) among critically-ill COVID-19 patients than previously reported, mainly affecting intubated-patients. Duration of mechanical ventilation and ICU stay were significantly longer in CAPA patients. [ABSTRACT FROM AUTHOR]

BACKGROUND: The coronavirus disease 2019 pandemic disrupted respiratory syncytial virus (RSV) seasonality resulting in early, atypical RSV seasons in 2021 and 2022, with an intense 2022 peak overwhelming many pediatric healthcare facilities. METHODS: We conducted prospective surveillance for acute respiratory illness during 2016-2022 at 7 pediatric hospitals.We interviewed parents, reviewed medical records, and tested respiratory specimens for RSV and other respiratory viruses.We estimated annual RSV-associated hospitalization rates in children aged <5 years and compared hospitalization rates and characteristics of RSV-positive hospitalized children over 4 prepandemic seasons (2016-2020) to those hospitalized in 2021 or 2022. RESULTS: There was no difference in median age or age distribution between prepandemic and 2021 seasons. Median age of children hospitalized with RSV was higher in 2022 (9.6 months vs 6.0 months, P < .001). RSV-associated hospitalization rates were higher in 2021 and 2022 than the prepandemic average across age groups. Comparing 2021 to 2022, RSV-associated hospitalization rates were similar among children <2 years of age; however, children aged 24 to 59 months had significantly higher rates of RSV-associated hospitalization in 2022 (rate ratio 1.68 [95% confidence interval 1.37-2.00]). More RSV-positive hospitalized children received supplemental oxygen and there were more respiratory virus codetections in 2022 than in prepandemic seasons (P < .001 and P 5 .003, respectively), but there was no difference in the proportion hypoxemic, mechanically ventilated, or admitted to intensive care. CONCLUSIONS: The atypical 2021 and 2022 RSV seasons resulted in higher hospitalization rates with similar disease severity to prepandemic seasons. [ABSTRACT FROM AUTHOR]

Introduction: Although thrombolytic therapy is the standard treatment for massive pulmonary thromboembolism (PTE), it is often ineffective in patients with circulatory collapse. Surgical embolectomy is another treatment option, but whether it is absolutely necessary is controversial. We sought to evaluate the outcomes of patients with massive PTE treated with intensive critical care including extracorporeal membrane oxygenation (ECMO) without thrombolytic therapy or surgical embolectomy. Methods: We analyzed 39 patients who were treated for massive PTE from January 2011 to June 2019. Massive PTE was treated with anticoagulation and hemodynamic support at an intensive care unit. ECMO was applied in patients with circulatory collapse. The computed tomography (CT) obstruction index and the ratio of the right ventricle to left ventricle short-axis diameters (RV/LV) were measured using serial CT angiography to confirm changes in pulmonary emboli and RV strain. Results: Twenty-one patients were in cardiogenic shock, and 15 of them needed cardiopulmonary resuscitation (CPR). Fifteen patients were treated with ECMO and nine of them were weaned successfully. The overall in-hospital mortality was 23% (9/39). On the follow-up CT scan after 6 months, residual PTE was observed in 10 patients and their median CT obstruction index was 6.25 % (range 2.5–35). The initial mean RV/LV ratio was 1.8 ± 0.47 and the value measured at follow-up CT decreased to less than 1 (0.9 ± 0.1). Conclusions: Intensive critical care with heparin alone and timely ECMO support without thrombolytic therapy could be an effective treatment option in patients with acute massive PTE.

Objective Fetal growth restriction (FGR) is defined as an estimated fetal weight (EFW) or abdominal circumference (AC) <10th percentile (%ile) for gestational age (GA). An EFW <3rd %ile for GA is considered severe FGR (sFGR). It remains unknown if fetuses with isolated AC <3rd %ile should be considered sFGR. Our primary objective was to assess composite neonatal outcomes in fetuses with an AC <3 rd %ile and overall EFW 3rd to 9th %ile compared with those with an EFW <3rd %ile. Study Design This retrospective cohort study was undertaken at a tertiary academic center from January 2016 to December 2021. Inclusion criteria were singleton fetuses with an EFW <3rd %ile (Group 1) or AC <3rd %ile with EFW 3rd to 9th %ile (Group 2) at 28 weeks' gestation or greater. Exclusion criteria were multiple gestations, presence of a major fetal anomaly, resolution of FGR, genetic syndrome, or infection. Composite neonatal outcome was defined by any of the following: neonatal intensive care unit admission >48 hours, necrotizing enterocolitis, sepsis, respiratory distress syndrome, mechanical ventilation, retinopathy of prematurity, seizures, intraventricular hemorrhage, stillbirth, or death before discharge. Small for gestational age (SGA) was defined as birth weight <10th %ile for GA. Results A total of 743 patients fulfilled our study criteria, with 489 in Group 1 and 254 in Group 2. The composite neonatal outcome occurred in 281 (57.5%) neonates in Group 1 and 53 (20.9%) in Group 2 (p < 0.01). The rates of SGA at birth were 94.9 and 75.6% for Group 1 and Group 2, respectively (OR 5.99, 95% confidence interval 3.65–9.82). Conclusion Although AC <3rd %ile with EFW 3rd to 9th %ile is associated with a lower frequency of SGA and neonatal morbidity than EFW <3 %ile, fetuses with AC <3 %ile still exhibited moderate rates of these adverse perinatal outcomes. Consideration should be given to inclusion of an AC <3rd %ile with EFW 3rd to 9th %ile as a criterion for sFGR. However, prospective studies comparing delivery at 37 versus 38 to 39 weeks' gestation are needed to ensure improved outcomes before widespread adaptation in clinical practice. Key Points The composite neonatal outcome occurred in 57.5% of fetuses with an overall EFW <3rd %ile and 20.9% of fetuses with an AC <3rd %ile but EFW 3rd to 9th %ile. Both groups demonstrated a high positive predictive value for SGA birth weight. Consideration should be given to inclusion of an AC <3rd %ile as a criterion for sFGR. [ABSTRACT FROM AUTHOR]

Invasive mechanical ventilation is prevalent and associated with considerable morbidity. Pediatric critical care teams must identify the best timing and approach to liberating (extubating) children from this supportive care modality. Unsurprisingly, practice variation varies widely. As a first step to minimizing that variation, the first evidence-based pediatric ventilator liberation guidelines were published in 2023 and included 15 recommendations. Unfortunately, there is often a substantial delay before clinical guidelines reach widespread clinical practice. As such, it is important to consider bar- riers and facilitators using a systematic approach during implementation planning and design. In this narrative review, we will (1) summarize guideline recommendations, (2) discuss recent evidence and identify practice gaps relating to those recommendations, and (3) hypothesize about potential barriers and facilitators to their implementation in clinical practice.
