Background: Anthropometric measurements are crucial in pediatric critical care, but the impact of height on ICU outcomes is underexplored despite a substantial number of short-for-age children in ICUs. Previous studies suggest that short stature increases the risk of poor clinical outcomes. This study examines the relationship between short stature and ICU outcomes. Methods: We conducted a retrospective cohort study using a Japanese nationwide database (the Japanese Intensive Care Patient Database; JIPAD), which included pediatric patients under 16 years admitted to ICUs from April 2015 to March 2020. Height standard deviation scores (SD scores) were calculated based on age and sex. Short-stature patients were defined as height SD score < − 2. The primary outcome was all-cause ICU mortality, and the secondary outcome was the length of stay in ICU. Results: Out of 6,377 pediatric patients, 27.2% were classified as having short stature. The ICU mortality rate was significantly higher in the short-stature group compared to the normal-height group (3.6% vs. 1.4%, p < 0.01). Multivariable logistic regression showed that short stature was independently associated with increased ICU mortality (OR = 2.73, 95% CI 1.81–4.11). Additionally, the Fine–Gray subdistribution hazards model indicated that short stature was associated with a lower chance of ICU discharge for each additional day (HR 0.85, 95% CI 0.81–0.90, p < 0.01). Conclusions: Short stature is a significant risk factor for increased ICU mortality and prolonged ICU stay in critically ill children. Height should be considered in risk assessments and management strategies in pediatric intensive care to improve outcomes. [ABSTRACT FROM AUTHOR]

Background: Mechanical ventilation (MV) can cause diaphragmatic injury and ventilator induced diaphragmatic dysfunction (VIDD). Diaphragm ultrasonography (DU) is increasingly used to assess diaphragmatic anatomy, function and pathology of patients receiving MV in the pediatric intensive care unit (PICU). We report the poor contractile ability of diaphragm during ventilation of critically ill patients in our PICU and the association to prolonged length of MV and PICU stay. Methods: Patients who received MV within 24 h of admission to the PICU, expected to undergo continuous MV for more than 48 h and succeeded to extubate were included in the study. DU monitoring was performed daily after the initiation of MV until extubation. Diaphragm thickening fraction (DTF) measured by DU was used as an indicator of diaphragmatic contractile activity. Patients with bilateral DTF = 0% during DU assessment were allocated into the severe VIDD group (n = 26) and the rest were into non-severe VIDD group (n = 29). The association of severe VIDD with individual length of MV, hospitalization and PICU stay were analyzed. Results: With daily DU assessment, severe VIDD occurred on 2.9 ± 1.2 days after the initiation of MV, and lasted for 1.9 ± 1.7 days. Values of DTF of all patients recovered to > 10% before extubation. The severe VIDD group had a significantly longer duration (days) of MV [12.0 (8.0-19.3) vs. 5.0 (3.5–7.5), p < 0.001] and PICU stay (days) [30.5 (14.9–44.5) vs. 13.0 (7.0-24.5), p < 0.001]. The occurrence of severe VIDD, first day of severe VIDD and length of severe VIDD were significantly positively associated with the duration of MV and PICU stay. The occurrence of severe VIDD on the second and third days after initiation of MV significantly associated to longer PICU stay (days) [43.0 (9.0–70.0) vs. 13.0 (3.0–40.0), p = 0.009; 36.0 (17.0-208.0) vs. 13.0 (3.0–40.0), p = 0.005, respectively], and the length of MV (days) was significantly longer in those with severe VIDD on the third day after initiation of MV [16.5 (7.0–29.0) vs. 5.0 (2.0–22.0), p = 0.003]. Conclusions: Daily monitoring of diaphragmatic function with bedside ultrasonography after initiation of MV is necessary in critically ill patients in PICU and the influences and risk factors of severe VIDD need to be further studied.

Introduction: In the United States (US), racial and socioeconomic disparities have been implicated in pediatric intensive care unit (PICU) admissions and outcomes, with higher rates of critical illness in more deprived areas. The degree to which this persists despite insurance coverage is unknown. We investigated whether disparities exist in PICU admission and mortality according to socioeconomic position and race in children receiving Medicaid. Methods: Using Medicaid data from 2007–2014 from 23 US states, we tested the association between area level deprivation and race on PICU admission (among hospitalized children) and mortality (among PICU admissions). Race was categorized as Black, White, other and missing. Patient-level ZIP Code was used to generate a multicomponent variable describing area-level social vulnerability index (SVI). Race and SVI were simultaneously tested for associations with PICU admission and mortality. Results: The cohort contained 8,914,347 children (23·0% Black). There was no clear trend in odds of PICU admission by SVI; however, children residing in the most vulnerable quartile had increased PICU mortality (aOR 1·12 (95%CI 1·04–1·20; p = 0·0021). Black children had higher odds of PICU admission (aOR 1·04; 95% CI 1·03–1·05; p < 0·0001) and higher mortality (aOR 1·09; 95% CI 1·02–1·16; p = 0·0109) relative to White children. Substantial state-level variation was apparent, with the odds of mortality in Black children varying from 0·62 to 1·8. Conclusion: In a Medicaid cohort from 2007–2014, children with greater socioeconomic vulnerability had increased odds of PICU mortality. Black children were at increased risk of PICU admission and mortality, with substantial state-level variation. Our work highlights the persistence of sociodemographic disparities in outcomes even among insured children. [ABSTRACT FROM AUTHOR]

Automated pupillometry (AP) facilitates objective pupillary assessment. In this study, we aimed at assessing nursing perspective about the utility of AP in neurocritically ill children to understand acceptance and usage barriers to guide development of a standardized use protocol. We conducted a web-based, cross-sectional, anonymous, Google™ survey of nurses at two independent pediatric ICUs which have been using AP over last four years. The survey included questions related to user-friendliness, barriers, acceptance, frequency of use, and method of documenting AP findings. A total of 31 nurses responded to the survey. A total of 25 nurses (80.6%) used the automated pupillometer and 19 (61.3%) nurses preferred to use the automated pupillometer on critically ill intubated patients. Respondents rated the pupillometer a median [IQR] frequency of use of 7/10 [4–9] and a mean user-friendliness of 8/10 [7–10]. Barriers to pupillometer use included pupillometer unavailability, technical issues, lack of perceived clinical significance, and infection control. Nurses have widely adopted the use of automated pupillometer in the PICU especially for critically ill intubated patients and rate it favorably for user-friendliness. Barriers against its use include limited resources, infection concerns, technical issues, and a lack of perceived clinical significance and training. Implementation of standardized PICU protocol for AP usage in critically ill children, may enhance the acceptance, increase usage and aid in objective assessments. These findings can be used to create a standardized protocol on implementing automated pupillometry in the PICU for critically ill children. • Nurses favor automated pupillometry for critically ill patients. • Nurses rate automated pupillometry high for user-friendliness. • Our survey revealed many key barriers to its pupillometer use. • Implement standardized protocol for effective pupillometer adoption.

In pediatric critical care, nurses are the primary caregivers for critically ill children and are particularly vulnerable to moral distress. There is limited evidence on what approaches are effective to minimize moral distress among these nurses. To identify intervention attributes that critical care nurses with moral distress histories deem important to develop a moral distress intervention. We used a qualitative description approach. Participants were recruited using purposive sampling between October 2020 to May 2021 from pediatric critical care units in a western Canadian province. We conducted individual semi-structured interviews via Zoom. A total of 10 registered nurses participated in the study. Four main themes were identified: (1) "I'm sorry, there's nothing else": increasing supports for patients and families; (2) "someone will commit suicide": improving supports for nurses: (3) "Everyone needs to be heard": improving patient care communication; and (4) "I didn't see it coming": providing education to mitigate moral distress. Most participants stated they wanted an intervention to improve communication among the healthcare team and noted changes to unit practices that could decrease moral distress. This is the first study that asks nurses what is needed to minimize their moral distress. Although there are multiple strategies in place to help nurses with difficult aspects of their work, additional strategies are needed to help nurses experiencing moral distress. Moving the research focus from identifying moral distress towards developing effective interventions is needed. Identifying what nurses need is critical to develop effective moral distress interventions. [ABSTRACT FROM AUTHOR]

Objective: Physicians often use mobile apps for patient care, but few apps are dedicated to pediatric critical care medicine (PCCM). This study developed a mobile app specifically for Pediatric Critical Care Unit (PICU) residents to aid their onboarding process and aimed to assess whether it could enhance their confidence and comfort levels. Method: From March 2020 to April 2021, 90 residents participated and completed pre- and post-rotation quizzes with 20 questions each. Quiz score differences between the control and app groups were analyzed using t-tests. A survey was also administered at the end of the rotation to compare comfort level and confidence in PCCM knowledge pre- and post-rotation. Results: Enrollment included 50 residents in the control group and 40 in the app group. The participation rate was 100%, but not all participants completed both quizzes and survey. The app group showed a significantly greater improvement in quiz scores from pre- to post-rotation compared to the control group (increase of 0.23 questions vs 1.67, p = 0.045). However, the two groups had no significant differences in confidence in PCCM knowledge (p = 0.246) or comfort levels (p = 0.776) in the PICU. Conclusions: This study found no significant difference in confidence levels between the App and control groups at the end of the PICU rotation. However, the App group outperformed the control group in knowledge assessments. Frequent use of the app likely reinforced essential concepts and facilitated adaptation to the PICU service. Overall, the app's positive impact on knowledge and adaptation indicates it is a valuable tool for enhancing medical residents' educational experiences in busy clinical environments.

Tracheal intubation in pediatric patients is a clinical scenario that can quickly become an emergency. Complication rates can potentially reach up to 60% in rapid sequence intubation. An alternate to this is delayed sequence intubation, which may reduce potential complications—mostly hypoxemia—and can be especially useful in non-cooperative children. This technique consists of the prior airway and oxygenation optimization. This is done through sedation using agents that preserve ventilatory function and protective reflexes and continuous oxygen therapy—prior and after the anesthetic induction—using nasal prongs. The objective of this narrative review is to provide a broader perspective on delayed sequence intubation by defining the concept and indications; reviewing its safety, effectiveness, and complications; and describing the anesthetic agents and oxygen therapy techniques used in this procedure.

Background: Immediate extubation is becoming more common in liver transplantation. However, limited data exist on how to identify pediatric patients with potential for successful immediate extubation and how this intervention may affect recovery. Methods: This retrospective review evaluated patients who underwent liver transplantation from 2015 to 2021 at Children's Healthcare of Atlanta. Preoperative status and intraoperative management were evaluated and compared. Outcomes comprised thrombosis, surgical reexploration, retransplantation, as well as reintubation, high flow nasal cannula (HFNC) usage, postoperative infection, the length of stay (LOS), and mortality. Results: A total of 173 patients were analyzed, with 121 patients (69.9%) extubated immediately. The extubation group had older age (median 4.0 vs 1.25 years, p =.048), lower PELD/MELD (28 vs. 34, p =.03), decreased transfusion (10.2 vs. 41.7 mL/kg, p <.001), shorter surgical time (332 vs. 392 min, p <.001), and primary abdominal closure (81% vs. 40.4%, p <.001). Immediate extubation was associated with decreased HFNC (0.21 vs. 0.71 days, p =.02), postoperative infection (9.9% vs. 26.9%, p =.007), mortality (0% vs. 5.8%, p =.036), and pediatric intensive care unit LOS (4.7 vs. 11.4 days, p <.001). The complication rate was lower in the extubation group (24.8% vs. 36.5%), but not statistically significant. Conclusions: Approximately 70% of patients were able to be successfully extubated immediately, with only 2.5% requiring reintubation. Those immediately extubated had decreased need for HFNC, lower infection rates, shorter LOS, and decreased mortality. Our results show that with proper patient selection and a multidisciplinary approach, immediate extubation allows for improved recovery without increased respiratory complications after pediatric liver transplantation.

Life-saving pediatric burn care is often initiated in hospitals that are not designated as a pediatric burn center. Therefore, familiarity with critical care of pediatric burn patients is crucial for physicians working in all healthcare settings equipped to care for children. Management of airway, mechanical ventilation, preservation of ideal circulatory status, and establishment of vascular access in pediatric burn patients requires many unique considerations. This article aims to summarize important principles of critical care of children with significant burn injuries for review by physicians and surgeons working in hospitals designated as a pediatric burn center and those that stabilize these patients prior to referral.

Background: Pneumonia is a major public health problem with an impact on morbidity and mortality. Its management still represents a challenge. The aim was to determine whether a new diagnostic algorithm combining lung ultrasound (LUS) and procalcitonin (PCT) improved pneumonia management regarding antibiotic use, radiation exposure, and associated costs, in critically ill pediatric patients with suspected bacterial pneumonia (BP). Methods: Randomized, blinded, comparative effectiveness clinical trial. Children < 18y with suspected BP admitted to the PICU from September 2017 to December 2019, were included. PCT was determined at admission. Patients were randomized into the experimental group (EG) and control group (CG) if LUS or chest X-ray (CXR) were done as the first image test, respectively. Patients were classified: 1.LUS/CXR not suggestive of BP and PCT < 1 ng/mL, no antibiotics were recommended; 2.LUS/CXR suggestive of BP, regardless of the PCT value, antibiotics were recommended; 3.LUS/CXR not suggestive of BP and PCT > 1 ng/mL, antibiotics were recommended. Results: 194 children were enrolled, 113 (58.2%) females, median age of 134 (IQR 39–554) days. 96 randomized into EG and 98 into CG. 1. In 75/194 patients the image test was not suggestive of BP with PCT < 1 ng/ml; 29/52 in the EG and 11/23 in the CG did not receive antibiotics. 2. In 101 patients, the image was suggestive of BP; 34/34 in the EG and 57/67 in the CG received antibiotics. Statistically significant differences between groups were observed when PCT resulted < 1 ng/ml (p = 0.01). 3. In 18 patients the image test was not suggestive of BP but PCT resulted > 1 ng/ml, all of them received antibiotics. A total of 0.035 mSv radiation/patient was eluded. A reduction of 77% CXR/patient was observed. LUS did not significantly increase costs. Conclusions: Combination of LUS and PCT showed no risk of mistreating BP, avoided radiation and did not increase costs. The algorithm could be a reliable tool for improving pneumonia management. Clinical Trial Registration: NCT04217980. [ABSTRACT FROM AUTHOR]

Background: Coronavirus disease 2019 (COVID-19) tends to have mild presentations in children. However, severe and critical cases do arise in the pediatric population with debilitating systemic impacts and can be fatal at times, meriting further attention from clinicians. Meanwhile, the intricate interactions between the pathogen virulence factors and host defense mechanisms are believed to play indispensable roles in severe COVID-19 pathophysiology but remain incompletely understood. Data sources: A comprehensive literature review was conducted for pertinent publications by reviewers independently using the PubMed, Embase, and Wanfang databases. Searched keywords included "COVID-19 in children", "severe pediatric COVID-19", and "critical illness in children with COVID-19". Results: Risks of developing severe COVID-19 in children escalate with increasing numbers of co-morbidities and an unvaccinated status. Acute respiratory distress stress and necrotizing pneumonia are prominent pulmonary manifestations, while various forms of cardiovascular and neurological involvement may also be seen. Multiple immunological processes are implicated in the host response to COVID-19 including the type I interferon and inflammasome pathways, whose dysregulation in severe and critical diseases translates into adverse clinical manifestations. Multisystem inflammatory syndrome in children (MIS-C), a potentially life-threatening immune-mediated condition chronologically associated with COVID-19 exposure, denotes another scientific and clinical conundrum that exemplifies the complexity of pediatric immunity. Despite the considerable dissimilarities between the pediatric and adult immune systems, clinical trials dedicated to children are lacking and current management recommendations are largely adapted from adult guidelines. Conclusions: Severe pediatric COVID-19 can affect multiple organ systems. The dysregulated immune pathways in severe COVID-19 shape the disease course, epitomize the vast functional diversity of the pediatric immune system and highlight the immunophenotypical differences between children and adults. Consequently, further research may be warranted to adequately address them in pediatric-specific clinical practice guidelines. [ABSTRACT FROM AUTHOR]

Background: Acute kidney injury (AKI) is a recognized comorbidity in pediatric diabetic ketoacidosis (DKA), although the exact etiology is unclear. The unique physiology of DKA makes dehydration assessments challenging, and these patients potentially receive excessive amounts of intravenous fluids (IVF). We hypothesized that dehydration is over-estimated in pediatric DKA, leading to over-administration of IVF and hyperchloremia that worsens AKI. Methods: Retrospective cohort of all DKA inpatients at a tertiary pediatric hospital from 2014 to 2019. A total of 145 children were included; reasons for exclusion were pre-existing kidney disease or incomplete medical records. AKI was determined by change in creatinine during admission, and comparison to a calculated baseline value. Linear regression multivariable analysis was used to identify factors associated with AKI. True dehydration was calculated from patients' change in weight, as previously validated. Fluid over-resuscitation was defined as total fluids given above the true dehydration. Results: A total of 19% of patients met KDIGO serum creatinine criteria for AKI on admission. Only 2% had AKI on hospital discharge. True dehydration and high serum urea levels were associated with high serum creatinine levels on admission (p = 0.042; p < 0.001, respectively). Fluid over-resuscitation and hyperchloremia were associated with delayed kidney recovery (p < 0.001). Severity of initial AKI was associated with cerebral edema (p = 0.018). Conclusions: Dehydration was associated with initial AKI in children with DKA. Persistent AKI and delay to recovery was associated with hyperchloremia and over-resuscitation with IVF, potentially modifiable clinical variables for earlier AKI recovery and reduction in long-term morbidity. This highlights the need to re-address fluid protocols in pediatric DKA. [ABSTRACT FROM AUTHOR]

ObjectiveOur aim was to confirm whether extreme hyperoxemic events had been associated with excess mortality in our diverse critical care population.MethodsRetrospective analysis of 9 years of data collected in the pediatric and cardiothoracic ICUs in Children's Hospital Los Angeles was performed. The analysis was limited to those mechanically ventilated for at least 24 h, with at least 1 arterial blood gas measurement. An extreme hyperoxemic event was defined as a PaO2 of ≥300 torr. Multivariable logistic regression was used to assess the association of extreme hyperoxemia events and mortality, adjusting for confounding variables. Selected a-priori, these were Pediatric Risk of Mortality III predicted mortality, general or cardiothoracic ICU, number of blood gas measurements, as well as an abnormal blood gas measurements (pH 7.45, and PaO2 98% markedly increased the risk of a hyperoxemic event.ConclusionRetrospective analysis of critical care admissions showed that extreme hyperoxemic events were associated with higher mortality. Supplemental oxygen levels resulting in SpO2 > 98% should be avoided.

Intracranial hemorrhage (ICH) can be a devastating complication of extracorporeal life support (ECLS); however, studies on the timing of ICH detection by head ultrasound (HUS) are from 2 decades ago, suggesting ICH is diagnosed by day 5 of ECLS. Given advancements in imaging and critical care, our aim was to evaluate if the timing of ICH diagnosis in infants on ECLS support has changed. Patients

OBJECTIVE: Difficult analgosedation is common and challenging in the pediatric intensive care unit (PICU). It is important to study alternative and supplemental sedatives for when the first-line agents become insufficient. METHODS: In this retrospective chart-review study, we report our center's experience in using intermittent doses of enteral pentobarbital as an adjunct sedative in 13 difficult to sedate critically ill and mechanically ventilated children. We compare the average sedation score and cumulative doses of other sedatives (opioids, benzodiazepines and alpha-2 agonists) in the 24 hours before and 24 hours after enteral pentobarbital initiation. RESULTS: The addition of enteral pentobarbital was associated with lower State Behavioral State (SBS) scores in 8 out of the 13 patients and on average smaller doses of opioids (decreased by 11%), benzodiazepines (BZD) (decreased by 5%) and alpha-agonists (decreased by 20%). No adverse effects were noted attributable to pentobarbital administration. CONCLUSION: Enteral pentobarbital seems to be safe and effective agent in the difficult to sedate critically ill child.

BACKGROUND: Timely ventilator liberation can prevent morbidities associated with invasive mechanical ventilation in the pediatric ICU (PICU). There currently exists no standard benchmark for duration of invasive mechanical ventilation in the PICU. This study sought to develop and validate a multi-center prediction model of invasive mechanical ventilation duration to determine a standardized duration of invasive mechanical ventilation ratio. METHODS: This was a retrospective cohort study using registry data from 157 institutions in the Virtual Pediatric Systems database. The study population included encounters in the PICU between 2012-2021 involving endotracheal intubation and invasive mechanical ventilation in the first day of PICU admission who received invasive mechanical ventilation for > 24 h. Subjects were stratified into a training cohort (2012-2017) and 2 validation cohorts (2018-2019/2020-2021). Four models to predict the duration of invasive mechanical ventilation were trained using data from the first 24 h, validated, and compared. RESULTS: The study included 112,353 unique encounters. All models had observed-to-expected (O/E) ratios close to one but low mean squared error and R² values. The random forest model was the best performing model and achieved an O/E ratio of 1.043 (95% CI 1.030-1.056) and 1.004 (95% CI 0.990-1.019) in the validation cohorts and 1.009 (95% CI 1.004-1.016) in the full cohort. There was a high degree of institutional variation, with single- unit O/E ratios ranging between 0.49-1.91. When stratified by time period, there were observ- able changes in O/E ratios at the individual PICU level over time. CONCLUSIONS: We derived and validated a model to predict the duration of invasive mechanical ventilation that performed well in aggregated predictions at the PICU and the cohort level. This model could be beneficial in quality improvement and institutional benchmarking initiatives for use at the PICU level and for tracking of performance over time. [ABSTRACT FROM AUTHOR]

ObjectivesPrimary objective is to determine if transfusion of short storage RBCs compared with standard issue RBCs reduced risk of delirium/coma in critically ill children. Secondary objective is to assess if RBC transfusion was independently associated with delirium/coma.DesignThis study was performed in two stages. First, we compared patients receiving either short storage or standard RBCs in a multi-institutional prospective randomized controlled trial. Then, we compared all transfused patients in the randomized controlled trial with a single-center cohort of nontransfused patients matched for confounders of delirium/coma.SettingTwenty academic PICUs who participated in the Age of Transfused Blood in Critically Ill Children trial.PatientsChildren 3 days to 16 years old who were transfused RBCs within the first 7 days of admission.InterventionsSubjects were randomized to either short storage RBC study arm (defined as RBCs stored for up to seven days) or standard issue RBC study arm. In addition, subjects were screened for delirium prior to transfusion and every 12 hours after transfusion for up to 3 days.Measurements and main resultsPrimary outcome measure was development of delirium/coma within 3 days of initial transfusion. Additional outcome measures were dose-response relationship between volume of RBCs transfused and delirium/coma, and comparison of delirium/coma rates between transfused patients and individually matched nontransfused patients. We included 146 subjects in the stage I analysis; 69 were randomized to short storage RBCs and 77 to standard issue. There was no significant difference in delirium/coma development between study arms (79.5% vs 70.1%; p = 0.184). In the stage II analysis, adjusted odds for delirium in the transfused cohort was more than eight-fold higher than in the nontransfused matched cohort, even after controlling for hemoglobin (adjusted odds ratio, 8.9; CI, 2.8-28.4; p < 0.001).ConclusionsRBC transfusions (and not anemia) are independently associated with increased odds of subsequent delirium/coma. However, storage age of RBCs does not affect delirium risk.

Background: Vein of Galen malformation (VGM) is a congenital intracranial vascular anomaly consisting of arteriovenous fistulas and/or malformations between various arterial feeders and the median prosencephalic vein of Markowski (MPV). Despite its rare occurrence, VGM is of particular clinical relevance, as the excessive intracranial shunt volume leads to high mortality without appropriate treatment. Methods: The objective of this article is to review the published data on neurointerventional treatment and compare outcome quality in the included studies. Eight studies were included and synthesized. One study was multicentric and the rest were retrospective monocentric (level 4 evidence studies according to the Oxford Centre for Evidence-based Medicine). Results: The total number of included patients was 480 and patient age ranged from 1 day to 18 years. Mild or severe heart failure, hydrocephalus, and other reasons led to the indication for neurointerventional treatment, which was performed in all studies in the form of embolization. Under consideration of the introduced semiquantitative multidimensional scoring system, the highest total score, i.e., the best outcome quality, was found for the study “Houston” 2002–2018 (19 points) and the study “Duisburg” 2001–2010 (19 points). Conclusions: Neurointerventional treatment represents the essential pillar in the interdisciplinary management of patients with VGM, although standardization is lacking—based on the results of the structured review. As complementary treatments, pediatric critical care is mandatory and includes medical hemodynamic stabilization.

Abstract Background To explore the impact of the transition from a traditional face-to-face course delivering essential contents in pediatric critical care to a hybrid format consisting of an online pre-course self-directed learning, an online facilitated discussion, and a face-to-face edition. Methods Attendees and faculty were surveyed after the face-to-face course and the hybrid version to evaluate the effectiveness and satisfaction of participants with the course. Results Fifty-seven students attended multiple formats of the Pediatric Basic Course between January 2020 and October 2021 in Udine, Italy. We compared course evaluation data from the 29 attendees of the face-to-face course with the 28 of the hybrid edition. Data collected included participant demographics, participant self-assessed pre and post-course ‘‘confidence’’ with a range of pediatric intensive care-related activities, and their satisfaction with elements of the course. There were no statistical differences in participant demographics or pre and post-course confidence scores. Overall satisfaction with the face-to-face course was marginally higher, 4.59 vs. 4.25/5, but did not reach significance. Pre-recorded lectures which could be viewed several times, were highlighted as a positive for the hybrid course. Residents found no significant differences comparing the two courses in rating the lectures and the technical skills stations. Hybrid course facilities (online platform and uploaded material) were reported to be clear, accessible, and valuable by 87% of attendees. After six months, they still find the course relevant to their clinical practice (75%). Candidates considered the respiratory failure and mechanical ventilation modules the most relevant modules. Conclusions The Pediatric Basic Course helps residents strengthen their learning and identify areas to improve their knowledge. Both face-to-face and hybrid model versions of the course improved attendees’ knowledge and perceived confidence in managing the critically ill child.

Background: Asthma is a common cause of admission to the pediatric intensive care unit (PICU). We described and analyzed the therapies applied to children admitted to a tertiary PICU because of asthma. Later, we evaluated high-flow nasal cannula (HFNC) use in these patients and compared their evolution and complications with those who received non-invasive ventilation. Methods: We conducted a prospective observational study (October 2017-October 2019). Collected data: epidemiological, clinical, respiratory support therapy needed, complementary tests, and PICU and hospital stay. Patients were divided into three groups: (1) only HFNC; (2) HFNC and non-invasive mechanical ventilation (NIMV); and (3) only NIMV. Results: Seventy-six patients were included (39 female). The median age was 2 years and 1 month. The median pulmonary score was 5. The median PICU stay was 3 days, and the hospital stay was 6 days. Children with HNFC only (56/76) had fewer PICU days (p = 0.025) and did not require NIMV (6/76). Children with HFNC had a higher oxygen saturation/fraction of inspired oxygen ratio ratio (p = 0.025) and lower PCO2 (p = 0.032). In the group receiving both therapies (14/76), NIMV was used first in all cases. No epidemiologic or clinical differences were found among groups. Conclusion: HFNC was a safe approach that did not increase the number of PICU or hospital days. On admission, normal initial blood gases and the absence of high oxygen requirements were useful in selecting responders to HFNC. Further randomized and multicenter clinical trials are needed to verify these data. [ABSTRACT FROM AUTHOR]

Early Mobilization (EM) in Pediatric Intensive Care Units (PICU) is safe, feasible and improves outcomes for PICU patients, yet patient safety concerns persist among nurses which limits EM adoption. The purpose of this study was to explore how nurses incorporate EM into practice and balance their concerns for patient safety with the benefits of EM. This focused ethnographic study included 15 in-depth interviews with 10 PICU nurses. Data were analyzed using thematic analysis. Two major categories were found which describe the clinical judgement and decision-making of PICU nurses regarding EM. The nurses' concerns for patient safety was the first major category. This included patient-level factors: hemodynamic stability, devices attached, patient's strength, and risk for falls and size. In the second major category, these safety concerns were overcome by applying a multiple step process which resulted in nurses performing EM despite their concerns. That process included: gaining comfort through experience, performing patient safety checks, working with therapists, learning from adverse events, and understanding existing evidence about the benefits of EM. The overarching theme was nurses' determination to preserve patient safety while ensuring patients could receive the benefits of EM. This theme describes the decisions, behaviors and processes that nurses enact to become more comfortable with EM despite their concerns for patient safety and potential adverse events while performing mobility activities. Creating opportunities for nurses to participate in EM may increase their willingness to overcome safety concerns and engage in these activities. • Nurses who trained and worked closely with therapists were more comfortable implementing early mobilization. • Future research should gather perceptions of early mobilization from the interdisciplinary team and from more nurses. This will facilitate a deeper and more comprehensive picture of perceptions of early mobilization from the providers based in multiple disciplines necessary to implement EM. • Future research may also explore how champions address barriers by providing real time feedback and education while reinforcing patient safety.

The accurate prediction of the prognosis for critically ill children is crucial, with the Pediatric Index of Mortality (PIM) and Pediatric Risk of Mortality (PRISM) being extensively utilized for this purpose. Albumin, C-reactive protein (CRP), and lactate levels, which are indicative of inflammation and circulatory status in critically ill children, have not been incorporated into existing scoring systems. This retrospective cohort study evaluated the association between biological markers and the clinical outcomes in children with critical illnesses. PRISM-4 and PIM-3 death probability (DP), albumin, lactate, CRP, and CRP/albumin ratio were recorded upon admission. The accuracy of the indexes in predicting mortality were assessed by calculating the area under the curve (AUC). There were 942 patients included and the 28-day mortality rate was 7.9%. The AUC for PRISM-4, PIM-3, CRP, CRP/albumin ratio, albumin, and lactate were 0.923, 0.896, 0.798, 0.795, 0.751, 0.728, respectively. The findings in the subgroup analysis of septic patients were similar to those found in the overall population. Although CRP, CRP/albumin ratio, albumin, and lactate levels are all linked to mortality in children, CRP and the CRP/albumin ratio have lower predictive values than albumin and lactate. Incorporation of albumin and lactate into scoring systems will improve predictability. [ABSTRACT FROM AUTHOR]

Objective: To determine the incidence of newly acquired morbidity, its categorization, and to identify the associated risk factors among children upon being discharged from the PICU. Study Design: Prospective Longitudinal Cohort study. Setting: Multidisciplinary PICU of Aga Khan University Hospital. Period: October 2022 to March 2023. Material & Methods: Patients who were readmitted to the PICU, deceased, or lost to follow-up during the study were excluded. The functional status was assessed using FSS at baseline, PICU discharge, and at 3 months to measure newly acquired morbidity and dysfunction. All data was collected on a structured proforma. Categorical variables were presented as absolute values and percentages, and continuous variables were expressed as means ± SD or medians with interquartile range or proportions as applicable and considered statistically significant level if p value is = 0.05. Results: A total 96 patients were discharged alive from PICU and 85 of them were included in this study. The mean age was 5.27 ± 5.01 years. The major diagnostic categories were acute respiratory illnesses (25.89%), cardiovascular disorders (21.18%), and neurological disorders (16.47%). 43.53% of the patients underwent surgical intervention. The mean PRISM score at admission was 4.32 ± 5.84. The incidence of morbidity was 40% (34/85) at PICU discharge and 5.8% at 3 months. Longer duration of vasoactive medications, arterial catheterization, mechanical ventilation and PICU stay were associated with new morbidity in critically ill children on discharge from PICU. Conclusion: At PICU discharge, the incidence of new morbidity among critically ill pediatric patients was 40%, which reduced to 5.8% at 3 months. Patients with hemodynamic instability, longer duration of inotropic support and those on prolonged mechanical ventilation had longer PICU stay and exhibited increased risk for new morbidity development. The majority of patients (>82%) exhibited either good functional status or mild dysfunction upon discharge. [ABSTRACT FROM AUTHOR]

BackgroundWe aimed to evaluate the effects of interfacility pediatric critical care transport response time, physician presence during transport, and mode of transport on mortality and length of stay (LOS) among pediatric patients. We hypothesized that a shorter response time and helicopter transports, but not physician presence, are associated with lower mortality and a shorter LOS.MethodsRetrospective, single-center, cohort study of 841 patients (

Background: Over 40% of the global burden of sepsis occurs in children under 5 years of age, making pediatric sepsis the top cause of death for this age group. Prior studies have shown that outcomes in children with sepsis improve by minimizing the time between symptom onset and treatment. This is a challenge in resource-limited settings where access to definitive care is limited. Methods: A secondary analysis was performed on data from 1,803 patients (28 days-14 years old) who presented to the emergency department (ED) at Muhimbili National Hospital (MNH) from July 1, 2016 to June 30, 2017 with a suspected infection and ≥2 clinical systemic inflammatory response syndrome criteria. The objective of this study was to determine the relationship between delayed presentation to definitive care (>48 h between fever onset and presentation to the ED) and mortality, as well as the association between socioeconomic status (SES) and delayed presentation. Multivariable logistic regression models tested the two relationships of interest. We report both unadjusted and adjusted odds ratios and 95% confidence intervals. Results: During the study period, 11.3% (n = 203) of children who presented to MNH with sepsis died inhospital. Delayed presentation was more common in non-survivors (n = 90/151, 60%) compared to survivors (n = 614/1,353, 45%) (p ≤ 0.01). Children who had delayed presentation to definitive care, compared to those who did not, had an adjusted odds ratio for mortality of 1.85 (95% CI: 1.17-3.00). Conclusions: Delayed presentation was an independent risk factor for mortality in this cohort, emphasizing the importance of timely presentation to care for pediatric sepsis patients. Potential interventions include more efficient referral networks and emergency transportation systems to MNH. Additional clinics or hospitals with pediatric critical care may reduce pediatric sepsis mortality in Tanzania, as well as parental education programs for recognizing pediatric sepsis.

AimInfants and children who require specialized medical attention are admitted to neonatal and pediatric intensive care units (ICUs) for continuous and closely supervised care. Overnight in-house physician coverage is frequently considered the ideal staffing model. It remains unclear how often this is achieved in both pediatric and neonatal ICUs in Canada. The aim of this study is to describe overnight in-house physician staffing in Canadian pediatric and level-3 neonatal ICUs (NICUs) in the pre-COVID-19 era.MethodsA national cross-sectional survey was conducted in 34 NICUs and 19 pediatric ICUs (PICUs). ICU directors or their delegates completed a 29-question survey describing overnight staffing by resident physicians, fellow physicians, nurse practitioners, and attending physicians. A comparative analysis was conducted between ICUs with and without in-house physicians.ResultsWe obtained responses from all 34 NICUs and 19 PICUs included in this study. A total of 44 ICUs (83%) with in-house overnight physician coverage provided advanced technologies, such as extracorporeal life support, and included all ICUs that catered to patients with cardiac, transplant, or trauma conditions. Residents provided the majority of overnight coverage, followed by the Critical Care Medicine fellows. An attending physician was in-house overnight in eight (15%) out of the 53 ICUs, seven of which were NICUs. Residents participating in rotations in the ICU would often have rotation durations of less than 6 weeks and were often responsible for providing care during shifts lasting 20–24 h.ConclusionMost PICUs and level-3 NICUs in Canada have a dedicated in-house physician overnight. These physicians are mainly residents or fellows, but a notable variation exists in this arrangement. The potential effects on patient outcomes, resident learning, and physician satisfaction remain unclear and warrant further investigation.

BackgroundAlthough lung and diaphragm ultrasound are valuable tools for predicting weaning results in adults with MV, their relevance in children is debatable. The goal of this meta-analysis was to determine the predictive value of lung and diaphragm ultrasound in newborn weaning outcomes.MethodsFor eligible studies, the databases MEDLINE, Web of Science, Cochrane Library, PubMed, and Embase were thoroughly searched. The Quality Assessment of Diagnostic Accuracy Studies (QUADAS−2) method was used to evaluate the study's quality. Results were gathered for sensitivity, specificity, diagnostic odds ratio (DOR), and the area under the curve of summary receiver operating characteristic curves (AUSROC). To investigate the causes of heterogeneity, subgroup analyses and meta-regression were conducted.ResultsA total of 11 studies were suitable for inclusion in the meta-analysis, which included 828 patients. The pooled sensitivity and specificity of lung ultrasound (LUS) were 0.88 (95%CI, 0.85–0.90) and 0.81 (95%CI, 0.75–0.87), respectively. The DOR for diaphragmatic excursion (DE) is 13.17 (95%CI, 5.65–30.71). The AUSROC for diaphragm thickening fraction (DTF) is 0.86 (95%CI, 0.82–0.89). The most sensitive and specific method is LUS. The DE and DTF were the key areas where study heterogeneity was evident.ConclusionsLung ultrasonography is an extremely accurate method for predicting weaning results in MV infants. DTF outperforms DE in terms of diaphragm ultrasound predictive power.

Objective: Hospitalized children with cardiac disease have the highest rate of cardiac arrest compared to other disease types. Different intensive care unit (ICU) models exist, but it remains unknown whether resuscitation guideline adherence is different between cardiac ICUs (CICU) and general pediatric ICUs (PICU). We hypothesize there is no difference in resuscitation practices between unit types. Design: Retrospective observational study. Setting: The American Heart Association's Get With The Guidelines®-Resuscitation (GWTG-R) registry. Patients: Children < 18 years old with medical or surgical cardiac disease who had cardiopulmonary arrest from 2014 to 2018. Intervention: None. Measurements and Main Results: Events were assessed for compliance with GWTG-R achievement measures of time to first chest compressions ≤ 1 min, time to intravenous/intraosseous epinephrine ≤ 5 min, time to first shock ≤ 2 min for ventricular fibrillation (VF)/pulseless ventricular tachycardia (VT), and confirmation of endotracheal tube placement. Additional practices were evaluated for consistency with Pediatric Advanced Life Support (PALS) recommendations. Eight hundred and eighty-six patients were evaluated, 687 (79%) in CICUs and 179 (21%) in PICUs. 484 (56%) had surgical cardiac disease. There were no differences in GWTG-R achievement measures or PALS recommendations between ICU types in univariable or multivariable models. Amiodarone, lidocaine, and nonstandard medication use did not differ by unit type. Extracorporeal cardiopulmonary resuscitation (ECPR) was more common in CICUs for both medical (16% vs 7%) and surgical (25% vs 2.5%) categories (P <.0001). Conclusions: Resuscitation compliance for patients with cardiac disease is similar between CICUs and PICUs. Patients were more likely to receive ECPR in CICUs. Additional study should evaluate how ICU type affects arrest outcomes in children with cardiac disease. [ABSTRACT FROM AUTHOR]

Background : Hyperchloremia has been associated with acute kidney injury (AKI) in critically ill adult patients. Data is limited in pediatric patients. Our study sought to determine if an association exists between hyperchloremia and AKI in pediatric patients admitted to the intensive care unit (PICU). Methods: This is a single-center retrospective cohort study of pediatric patients admitted to the PICU for greater than 24 h and who received intravenous fluids. Patients were excluded if they had a diagnosis of kidney disease or required kidney replacement therapy (KRT) within 6 h of admission. Exposures were hyperchloremia (serum chloride ≥ 110 mmol/L) within the first 7 days of PICU admission. The primary outcome was the development of AKI using the Kidney Disease Improving Global Outcomes (KDIGO) criteria. Secondary outcomes included time on mechanical ventilation, new KRT, PICU length of stay, and mortality. Outcomes were analyzed using multivariate logistic regression. Results: There were 407 patients included in the study, 209 in the hyperchloremic group and 198 in the non-hyperchloremic group. Univariate analysis demonstrated 108 (51.7%) patients in the hyperchloremic group vs. 54 (27.3%) in the non-hyperchloremic group (p = <.001) with AKI. On multivariate analysis, the odds ratio of AKI with hyperchloremia was 2.24 (95% CI 1.39–3.61) (p =.001). Hyperchloremia was not associated with increased odds of mortality, need for KRT, time on mechanical ventilation, or length of stay. Conclusion: Hyperchloremia was associated with AKI in critically ill pediatric patients. Further pediatric clinical trials are needed to determine the benefit of a chloride restrictive vs. liberal fluid strategy. [ABSTRACT FROM AUTHOR]

Background: To explore the impact of the transition from a traditional face-to-face course delivering essential contents in pediatric critical care to a hybrid format consisting of an online pre-course self-directed learning, an online facilitated discussion, and a face-to-face edition. Methods: Attendees and faculty were surveyed after the face-to-face course and the hybrid version to evaluate the effectiveness and satisfaction of participants with the course. Results: Fifty-seven students attended multiple formats of the Pediatric Basic Course between January 2020 and October 2021 in Udine, Italy. We compared course evaluation data from the 29 attendees of the face-to-face course with the 28 of the hybrid edition. Data collected included participant demographics, participant self-assessed pre and post-course "confidence" with a range of pediatric intensive care-related activities, and their satisfaction with elements of the course. There were no statistical differences in participant demographics or pre and post-course confidence scores. Overall satisfaction with the face-to-face course was marginally higher, 4.59 vs. 4.25/5, but did not reach significance. Pre-recorded lectures which could be viewed several times, were highlighted as a positive for the hybrid course. Residents found no significant differences comparing the two courses in rating the lectures and the technical skills stations. Hybrid course facilities (online platform and uploaded material) were reported to be clear, accessible, and valuable by 87% of attendees. After six months, they still find the course relevant to their clinical practice (75%). Candidates considered the respiratory failure and mechanical ventilation modules the most relevant modules. Conclusions: The Pediatric Basic Course helps residents strengthen their learning and identify areas to improve their knowledge. Both face-to-face and hybrid model versions of the course improved attendees' knowledge and perceived confidence in managing the critically ill child. [ABSTRACT FROM AUTHOR]

Pediatric critical care is highly sophisticated and precise and is possible only in specialized areas such as pediatric intensive care units (PICUs) or high dependency units equipped with round-the-clock monitoring facilities, skilled and trained staff, and treatment equipment. The need for critical care beds was sharply felt during the COVID-19 pandemic and the Government of India launched the COVID-19 emergency response and health system preparedness package: phase II (ECRP-II) with a hub and spoke model to strengthen pediatric critical care delivery at district level under the skilled supervision of state-level PICUs of the identified center of excellence (CoE). The CoEs will have well-equipped PICUs providing tele-ICU service, mentoring, and technical hand-holding to the district pediatric unit. This model was envisioned to be extended to critically ill children with nonCOVID illnesses after the pandemic abates. For achieving the proposed objectives under the ECRP-II scheme, this guideline aims to provide a practical framework for setting up comprehensive pediatric care units at district hospitals and medical colleges (spoke) well connected with a CoE (hub) for teleconsultation, knowledge exchange, referral, and back referral between hub and spokes.

Summary: Background and aims: Meeting the nutritional requirements of critically ill infants and young children with breastmilk or formula alone is often challenging due to disease-related increased requirements and fluid restriction. ‘Feed modification’ is a nutrition therapy strategy to increase energy and protein density, and includes fortification of expressed breast milk, preparation of standard powdered formula at an increased concentration and utilisation of concentrated ready-to-feed liquid formulas. However, despite anecdotal evidence suggesting frequent and varied use internationally, the evidence for feed modification is unclear and has not been reviewed systematically. This article describes the methods for a scoping review to collate the key definitions, concepts, methods and evidence for use of modified feeds for increased energy and protein density as nutrition therapy in critically ill children. Methods: A scoping review will be completed, including searches of MEDLINE, Embase, Emcare and CINAHL databases. Grey literature will be searched using ProQuest, Web of Science, Trove Australian theses, WorldCat Dissertations and Theses, EThOS, Dart European and conference collections via Ovid. Study selection and data charting will be undertaken by two reviewers. Results of this review will be presented in a tabular format and include frequency counts. Literature related to use of feed modification for increased energy and protein density in children up to the age of 5 years from the year 2010 to present and in English language only will be included. This review will be the first of its kind and of interest to all areas of paediatrics utilising feed modification for increased energy and protein density.

Objective: To investigate the role of Complex Chronic Conditions (CCCs) on the outcomes of pediatric patients with refractory septic shock, as well as the accuracy of PELOD-2 and Vasoactive Inotropic Score (VIS) to predict mortality in this specific population. Methods: This is a single-center, retrospective cohort study. All patients diagnosed with septic shock requiring vasoactive drugs admitted to a 13-bed PICU in southern Brazil, between January 2016 and July 2018, were included. Clinical and demographic characteristics, presence of CCCs and VIS, and PELOD-2 scores were accessed by reviewing electronic medical records. The main outcome was considered PICU mortality. Results: 218 patients with septic shock requiring vasoactive drugs were identified in the 30-month period and 72% of them had at least one CCC. Overall mortality was 22%. Comparing to patients without previous comorbidities, those with CCCs had a higher mortality (26.7% vs 9.8%; OR = 3.4 [1.3–8.4]) and longer hospital length of stay (29.3 vs 14.8; OR 2.39 [1.1- 5.3]). Among the subgroups of CCCs, “Malignancy” was particularly associated with mortality (OR = 2.3 [1.0–5.1]). VIS and PELOD-2 scores in 24 and 48 hours were associated with mortality and a PELOD-2 in 48 hours > 8 had the best performance in predicting mortality in patients with CCC (AUROC = 0.89). Conclusion: Patients with CCCs accounted for the majority of those admitted to the PICU with septic shock and related to poor outcomes. The high prevalence of hospitalizations, use of resources, and significant mortality determine that patients with CCCs should be considered a priority in the healthcare system.
