Objectives To examine the proportionate use of critical care resources among children of differing medical complexity admitted to pediatric intensive care units (ICUs) in tertiary-care children's ...hospitals. Study design This is a retrospective, cross-sectional study of all children (<19 years of age) admitted to a pediatric ICU between January 1, 2012, and December 31, 2013, in the Pediatric Health Information Systems database. Using the Pediatric Medical Complexity Algorithm, we assigned patients to 1 of 3 categories: no chronic disease, noncomplex chronic disease (NC-CD), or complex chronic disease (C-CD). Baseline demographics, hospital costs, and critical care resource use were stratified by these groups and summarized. Results Of 136 133 children with pediatric ICU admissions, 53.0% were categorized as having C-CD. At the individual-encounter level, ICU resource use was greatest among patients with C-CD compared with children with NC-CD and no chronic disease. At the hospital level, patients with C-CD accounted for more than 75% of all examined ICU resources, including ventilation days, ICU costs, extracorporeal membrane oxygenation runs, and arterial and central venous catheters. Children with a progressive condition accounted for one-half of all ICU resources. In contrast, patients with no chronic disease and NC-CD accounted for less than one-quarter of all ICU therapies. Conclusion Children with medical complexity disproportionately use the majority of ICU resources in children's hospitals. Efforts to improve quality and provide cost-effective care should focus on this population.

Background
Burn injuries are a major cause of death and disability globally. The World Health Organization (WHO) launched the Global Burn Registry (GBR) to improve understanding of burn injuries ...worldwide, identify prevention targets, and benchmark acute care. We aimed to describe the epidemiology, risk factors, and outcomes of children with burns to demonstrate the GBR's utility and inform needs for pediatric burn prevention and treatment.
Methods
We performed descriptive analyses of children age ≤ 18 years in the WHO GBR. We also described facility-level capacity. Data were extracted in September of 2021.
Results
There were 8,640 pediatric and adult entries from 20 countries. Of these, 3,649 (42%) were children (0–18 years old) from predominantly middle-income countries. The mean age was 5.3 years and 60% were boys. Children aged 1–5 years comprised 62% (
n
= 2,279) of the cohort and mainly presented with scald burns (80%), followed by flame burns (14%). Children >5 years (
n
= 1,219) more frequently sustained flame burns (52%) followed by scald burns (29%). More than half of pediatric patients (52%) sustained a major burn (≥15% total body surface area) and 48% received surgery for wound closure during the index hospitalization. Older children had more severe injuries and required more surgery. Despite the frequency of severe injuries, critical care capacity was reported as “limited” for 23% of pediatric patients.
Conclusions
Children represent a large proportion of people with burn injuries globally and often sustain major injuries that require critical and surgical intervention. However, critical care capacity is limited at contributing centers and should be a priority for healthcare system development to avert preventable death and disability. This analysis demonstrates that the GBR has the potential to highlight key epidemiological characteristics and hospital capacity for pediatric burn patients. To improve global burn care, addressing barriers to GBR participation in low- and low-middle-income countries would allow for greater representation from a diversity of countries, regions, and burn care facilities.
Objectives: The intensive care unit (ICU) Liberation “ABCDEF” Bundle improves outcomes in critically ill adults. We aimed to identify common barriers to Pediatric ICU Liberation Bundle element ...implementation, to describe differences in barrier perception by ICU staff role, and to describe changes in reported barriers over time. Study Design: A 91-item survey was developed based on existing literature, iteratively revised, and tested by the PICU Liberation Committee at Seattle Children's Hospital, a tertiary free-standing academic children's hospital. Voluntary surveys were administered electronically to all ICU staff twice over 4-week periods in 2017 and 2020. Survey Respondents: 119 (2017) and 163 (2020) pediatric and cardiac ICU staff, including nurses (n = 142, 50%), respiratory therapists (RTs) (n = 46, 16%), attending and fellow physicians, hospitalists, and advanced practice providers (APPs) (n = 62, 22%), physical, occupational, and speech-language pathology therapists (n = 25, 9%), and pharmacists (n = 7, 2%). Measurements and Main Results: Respondents widely agreed that increased workload (78%-100% across roles), communication (53%-84%), and lack of RT-directed ventilator weaning (68%-88%) are barriers to implementation. Other barriers differed by role. In 2020, nurses reported liability (59%) and personal injury (68%) concerns, patient severity of illness (24%), and family discomfort with ICU liberation practices (41%) more frequently than physicians and APPs (16%, 6%, 8%, and 19%, respectively; P < .01 for all). Between 2017 and 2020, some barriers changed: RTs endorsed discomfort with early mobilization less frequently (50% vs 11%, P = .028) and nurses reported concern for patient harm less frequently (51% vs 24%, P = .004). Conclusions: Implementation efforts aimed at addressing known barriers, including educating staff on the safety of early mobility, considering respiratory therapist-directed ventilator weaning, and standardizing interdisciplinary discussion of Pediatric ICU Liberation Bundle elements, will be needed to overcome barriers and improve ICU Liberation Bundle implementation.

To determine whether long-term dexmedetomidine dosing is associated with lower opioid and benzodiazepine use without risk of significant hemodynamic changes and/or withdrawal.
Retrospective, ...observational study.
PICU, cardiovascular ICU, and neonatal ICU in a single, tertiary care, academic children's hospital.
We included all patients less than or equal to 21 years old, who received dexmedetomidine for greater than or equal to 72 hours from December 2008 to December 2010 resulting in a 98-subject cohort.
None.
The median duration of dexmedetomidine use was 141 hours. A decrease in systolic blood pressure and heart rate was seen after initiation of dexmedetomidine. After dexmedetomidine was discontinued, systolic blood pressure was statistically significantly higher than baseline. Similarly, heart rate showed a significant increase from baseline following discontinuation of dexmedetomidine. Starting dexmedetomidine was not associated with a significant difference in the dosing of opiates or benzodiazepines. Comfort scores were significantly lower at 2 and 72 hours of dexmedetomidine infusion. After stopping dexmedetomidine, the comfort score for patients at 1 hour was statistically higher than for patients at cessation of the infusion. Thirty percent of patients who were taken off dexmedetomidine, whether weaned or abruptly stopped, had withdrawal symptoms and scores recorded with agitation, tremor, and decreased sleep being most prominent.
Hemodynamic effects of dexmedetomidine did not limit long-term use in this diverse population. After the addition of dexmedetomidine, opioid and benzodiazepine doses did not significantly escalate, and patients were more comfortable as evidenced by decreasing comfort scores. Withdrawal from dexmedetomidine may be an issue and manifests as agitation, tremors, and decreased sleep.
Purpose:
Early warning scores (EWS) identify high-risk hospitalized patients prior to clinical deterioration; however, their ability to identify high-risk pediatric patients in the emergency ...department (ED) has not been adequately evaluated. We sought to determine the association between modified pediatric EWS (MPEWS) in the ED and inpatient ward-to-pediatric intensive care unit (PICU) transfer within 24 hours of admission.
Methods:
This is a case–control study of 597 pediatric ED patients admitted to the inpatient ward at Seattle Children’s Hospital between July 1, 2010, and December 31, 2011. Cases were children subsequently transferred to the PICU within 24 hours, whereas controls remained hospitalized on the inpatient ward. The association between MPEWS in the ED and ward-to-PICU transfer was determined by chi-square analysis.
Results:
Fifty children experienced ward-to-PICU transfer within 24 hours of admission. The area under the receiver–operator characteristic curve was 0.691. Children with MPEWS > 7 in the ED were more likely to experience ward-to-PICU transfer (odds ratio 8.36, 95% confidence interval 2.98-22.08); however, the sensitivity was only 18.0% with a specificity of 97.4%. Using MPEWS >7 for direct PICU admission would have led to 167 unnecessary PICU admissions and identified only 9 of 50 patients who required PICU care.
Conclusions:
Elevated MPEWS in the ED is associated with increased risk of ward-to-PICU transfer within 24 hours of admission; however, an MPEWS threshold of 7 is not sufficient to identify more than a small proportion of ward-admitted children with subsequent clinical deterioration.

To evaluate an empirically derived Low Cardiac Output Syndrome Score as a clinical assessment tool for the presence and severity of Low Cardiac Output Syndrome and to examine its association with ...clinical outcomes in infants who underwent surgical repair or palliation of congenital heart defects.
Prospective observational cohort study.
Cardiac ICU at Seattle Children's Hospital.
Infants undergoing surgical repair or palliation of congenital heart defects.
None.
Clinical and laboratory data were recorded hourly for the first 24 hours after surgery. A Low Cardiac Output Syndrome Score was calculated by assigning one point for each of the following: tachycardia, oliguria, toe temperature less than 30°C, need for volume administration in excess of 30 mL/kg/d, decreased near infrared spectrometry measurements, hyperlactatemia, and need for vasoactive/inotropes in excess of milrinone at 0.5 μg/kg/min. A cumulative Low Cardiac Output Syndrome Score was determined by summation of Low Cardiac Output Syndrome Score on arrival to cardiac ICU, and 8, 12, and 24 hours postoperatively. Scores were analyzed for association with composite morbidity (prolonged mechanical ventilation, new infection, cardiopulmonary arrest, neurologic event, renal dysfunction, necrotizing enterocolitis, and extracorporeal life support) and resource utilization. Fifty-four patients were included. Overall composite morbidity was 33.3%. Median peak Low Cardiac Output Syndrome Score and cumulative Low Cardiac Output Syndrome Score were higher in patients with composite morbidity (3 2-5 vs 2 1-3; p = 0.003 and 8 5-10 vs 2.5 1-5; p < 0.001). Area under the receiver operating characteristic curve for cumulative Low Cardiac Output Syndrome Score versus composite morbidity was 0.83, optimal cutoff of greater than 6. Patients with cumulative Low Cardiac Output Syndrome Score greater than or equal to 7 had higher morbidity, longer duration of mechanical ventilation, cardiac ICU, and hospital length of stay (all p ≤ 0.001). After adjusting for other relevant variables, peak Low Cardiac Output Syndrome Score and cumulative Low Cardiac Output Syndrome Score were independently associated with composite morbidity (odds ratio, 2.57; 95% CI, 1.12-5.9 and odds ratio, 1.35; 95% CI, 1.09-1.67, respectively).
Higher peak Low Cardiac Output Syndrome Score and cumulative Low Cardiac Output Syndrome Score were associated with increased morbidity and resource utilization among infants following surgery for congenital heart defects and might be a useful tools in future cardiac intensive care research. Independent validation is required.
The aim of this study was to evaluate outcomes of pediatric intensive care unit (PICU) patients with delirium treated with haloperidol or quetiapine compared with propensity-matched, untreated ...patients.
A single-center retrospective cohort study was conducted including PICU admissions of ≥ 48 h for children ≥ 2 months old with a positive delirium screening score (Cornell Assessment of Pediatric Delirium ≥ 9). We generated propensity scores for the likelihood of receiving treatment with haloperidol or quetiapine using logistic regression, and matched untreated to treated patients 2:1 to compare outcomes between groups.
Among 846 eligible admissions, 27 were treated with haloperidol or quetiapine (3.2%). Time to first delirium-free score was similar for treated versus untreated patients. Treated patients had no significant change in delirium scores following treatment, while untreated patients' scores improved after the comparable matching time. Compared with untreated patients, haloperidol-treated patients had more subsequent days of delirium and exposure to neuromuscular blockade. Quetiapine-treated patients had more subsequent days of mechanical ventilation and exposure to neuromuscular blockade, longer PICU length of stay, and higher likelihood of functional decline at ICU discharge.
In our small, single-center study, patients treated with haloperidol or quetiapine showed no short-term improvement in delirium screening scores after starting treatment when compared with untreated, propensity score-matched patients. In addition, clinical outcomes were not improved or were worse among treated patients. A prospective trial is needed to evaluate whether antipsychotic medications benefit PICU patients with delirium.

Objective:
End-tidal carbon dioxide (ETCO2) measurements during cardiopulmonary resuscitation (CPR) reflect variable cardiac output over time, and low values have been associated with decreased ...survival. The goals of this review are to confirm and quantify this relationship and to determine the mean ETCO2 value among patients with return of spontaneous circulation (ROSC) as an initial step toward determining an appropriate target for intervention during resuscitation in the absence of prospective data.
Data Sources and Study Selection:
The PubMed database was searched for the key words “end-tidal carbon dioxide” or “capnometry” or “capnography” and “resuscitation” or “return of spontaneous circulation.” Randomized controlled trials, cohort studies, or case–control studies that reported ETCO2 values for participants with and without ROSC were included.
Data Extraction and Synthesis:
Twenty-seven studies met the inclusion criteria for qualitative synthesis. Twenty studies were included in determination of average ETCO2 values. The mean ETCO2 in participants with ROSC was 25.8 ± 9.8 mm Hg versus 13.1 ± 8.2 mm Hg (P = .001) in those without ROSC. Nineteen studies were included in a meta-analysis. The mean difference in ETCO2 was 12.7 mm Hg (95% confidence interval: 10.3-15.1) between participants with and without ROSC (P < .001). The mean difference in ETCO2 was not modified by the receipt of sodium bicarbonate, uncontrolled minute ventilation, or era of resuscitation guidelines. The overall quality of data by Grades of Recommendations, Assessment, Development and Evaluation criteria is very low, but no prospective data are currently available.
Conclusions:
Participants with ROSC after CPR have statistically higher levels of ETCO2. The average ETCO2 level of 25 mm Hg in participants with ROSC is notably higher than the threshold of 10 to 20 mm Hg to improve delivery of chest compressions. The ETCO2 goals during resuscitation may be higher than previously suggested and further investigation into appropriate targets during resuscitation is needed to diminish morbidity and mortality after cardiorespiratory arrest.

Patients on extracorporeal life support (ECLS) are at risk for central nervous system (CNS) injury. One potentially modifiable risk factor is site of arterial cannulation in venoarterial (VA) ECLS, ...as in most cases one can choose the femoral or carotid artery. There is acute alteration in cerebral blood flow with carotid cannulation, potentially increasing the risk of stroke. Children may have lower risk of stroke with carotid cannulation compared with adults because of impaired cerebral circulation with aging. Our objective was to evaluate risk of stroke with carotid versus femoral cannulation and determine whether this differs between children and adults. Using the Extracorporeal Life Support Organization Registry, we evaluated patients 6–40 years old on VA ECLS during 2000–2012. We used multivariable logistic regression to estimate the relationship between location of arterial cannulation and stroke. We included an interaction term to assess whether this was modified by age. One thousand five hundred eighteen patients were included in the analysis. There was a fourfold increased odds of CNS infarct (odds ratio OR4.03; 95% CI2.17–7.46) with carotid cannulation. This estimate was not modified by age. There is increased likelihood of stroke with carotid cannulation in patients 6–40 years old in comparison with femoral cannulation during VA ECLS.
