To investigate the association between low near infrared spectroscopy (NIRS) somatic oxygen saturation (<70%) at admission and the need for lifesaving interventions (LSI) in the initial 24 h of a PICU admission. Retrospective chart review of all unplanned admissions to the pediatric intensive care unit (PICU) with NIRS somatic oxygen saturation data available within 4 h of admission, excluding admissions with a cardiac diagnosis. LSI data were collected for the first 24 h after admission. Hemodynamic parameters, laboratory values, illness severity scores and diagnoses were collected. Included PICU admissions were stratified by lowest NIRS value in the first 4 h after admission: low NIRS (<70%) and normal NIRS (≥70%) groups. Rate of LSI from 4 h to 24 h was compared between the two groups. Association of LSI with NIRS saturation and other clinical and laboratory parameters was measured by univariate and multivariate methods. We reviewed 411 consecutive unplanned admissions to the PICU of which 184 (44%) patients underwent NIRS monitoring. A higher proportion of patients who underwent somatic NIRS monitoring required LSIs compared to those without NIRS monitoring (36.4 vs 5.7% respectively, p < 0.0001). The proportion of patients who required LSI was higher in the group with low NIRS (<70%) within the first 4 h compared to those with normal NIRS (≥70%) (77.1 vs 22.1%, p < 0.0001). Fluid resuscitation, blood products and vasoactive medications were the most common LSIs. Multivariable modeling showed NIRS < 70% and heart rate > 2SD for age to be associated with LSIs. ROC curve analysis of the combination of NIRS < 70% and HR >2SD for age had an area under the curve of 0.79 with 78% sensitivity and 76% specificity for association with LSI. Compared to the normal NIRS group, the low NIRS group had higher mortality (10.4 vs 0.7%, p = 0.005) and longer median hospital length of stay (2.9 vs 1.6 days, p < 0.0001). Low somatic NIRS oxygen saturation (<70%) in the first 4 h of an unplanned PICU admission is associated with need for higher number of subsequent lifesaving interventions up to 24 h after admission. Noninvasive, continuous, somatic NIRS monitoring may identify children at high risk of medical instability.

Children with severe TBI and higher ISS were more likely to have delayed initiation of enteral nutrition. Delayed enteral nutrition was an independent risk factor for worse functional status at ICU discharge for the entire cohort, but not for the severe TBI group.

IMPORTANCE Families and clinicians have limited validated tools available to assist in estimating long-term outcomes early after pediatric cardiac arrest. Blood-based brain-specific biomarkers may be helpful tools to aid in outcome assessment. OBJECTIVETo analyze the association of blood-based brain injury biomarker concentrations with outcomes 1 year after pediatric cardiac arrest. DESIGN, SETTING, AND PARTICIPANTSThe Personalizing Outcomes After Child Cardiac Arrest multicenter prospective cohort study was conducted in pediatric intensive care units at 14 academic referral centers in the US between May 16, 2017, and August 19, 2020, with the primary investigators blinded to 1-year outcomes. The study included 120 children aged 48 hours to 17 years who were resuscitated after cardiac arrest, had pre-cardiac arrest Pediatric Cerebral Performance Category scores of 1 to 3 points, and were admitted to an intensive care unit after cardiac arrest. EXPOSURE Cardiac arrest. MAIN OUTCOMES AND MEASURESThe primary outcome was an unfavorable outcome (death or survival with a Vineland Adaptive Behavior Scales, third edition, score of <70 points) at 1 year after cardiac arrest. Glial fibrillary acidic protein (GFAP), ubiquitin carboxyl-terminal esterase L1 (UCH-L1), neurofilament light (NfL), and tau concentrations were measured in blood samples from days 1 to 3 after cardiac arrest. Multivariate logistic regression and area under the receiver operating characteristic curve (AUROC) analyses were performed to examine the association of each biomarker with outcomes on days 1 to 3. RESULTS Among 120 children with primary outcome data available, the median (IQR) age was 1.0 (0-8.5) year; 71 children (59.2%) were male. A total of 5 children (4.2%) were Asian, 19 (15.8%) were Black, 81 (67.5%) were White, and 15 (12.5%) were of unknown race; among 110 children with data on ethnicity, 11 (10.0%) were Hispanic, and 99 (90.0%) were non-Hispanic. Overall, 70 children (58.3%) had a favorable outcome, and 50 children (41.7%) had an unfavorable outcome, including 43 deaths. On days 1 to 3 after cardiac arrest, concentrations of all 4 measured biomarkers were higher in children with an unfavorable vs a favorable outcome at 1 year. After covariate adjustment, NfL

Objectives:The aim of this study was to investigate the role of near-infrared spectroscopy (NIRS) in identifying pediatric trauma patients who required lifesaving interventions (LSIs).Methods: Retrospective chart review of children age 0 to 18 years who activated the trauma team response between January 1, 2015 and August 14, 2017, at a large, urban pediatric emergency department. The lowest somatic NIRS saturation and the need for LSIs (based on published consensus definition) were abstracted from the chart. χ 2 and descriptive statistics were used for analysis. Results:The charts of 84 pediatric trauma patients were reviewed. Overall, 80% were boys with a mean age of 10.4 years (SD, 6.2 years). Injuries included 56% blunt trauma and 36% penetrating trauma with mortality of 10.7% (n = 9). Overall, the median lowest NIRS value was 67% (interquartile range, 51-80%; range, 15%-95%) and 54.8% of the patients had a NIRS value less than 70%. The median somatic NIRS duration recorded was 12 minutes (interquartile range, 6-17 minutes; range, 1-59 minutes). Overall, 50% of patients required a LSI, including 39 who required a lifesaving procedure, 11 required blood products, and 14 required vasopressors. Pediatric trauma patients with NIRS less than 70% had a significantly increased odds of requiring a LSI (odds ratio, 2.67; 95% confidence interval, 1.10-6.47). NIRS less than 70% had a sensitivity and specificity of 67% and 57% respectively.Conclusions: Pediatric trauma patients with somatic NIRS less than 70% within 30 minutes of emergency department arrival are associated with the need for LSIs. Continuous NIRS monitoring in the pediatric trauma population should be evaluated prospectively.

Post‐operative ileus is common after abdominal surgeries. Children undergoing liver transplant are at increased risk of ileus for various reasons including multiple abdominal procedures and use of narcotic medications. Ileus can lead to abdominal compartment syndrome and compromise the integrity of the liver graft. In some of these patients, ileus is resistant to standard therapies including stool softeners, bowel stimulants, enemas, and even methylnaltrexone. Neostigmine has been shown in pediatric case series to be efficacious in some children for refractory post‐operative ileus. We report three children (9 months, 3 years, and 12 years old) who developed refractory ileus after liver transplant, with one of them developing abdominal compartment syndrome, who were treated successfully with continuous infusions of neostigmine. Clinical responses included passage of flatus and stool and improvement in abdominal distension. All patients tolerated the infusion without serious adverse effects such as bradycardia or bronchospasm. Neostigmine was used safely in our patients and may be safe and efficacious for the treatment of refractory ileus in pediatric patients after liver transplantation. Neostigmine should be considered early in the treatment of these patients.

Background: Severe traumatic brain injury (sTBI) is the leading cause of morbidity and mortality from trauma. Brain Trauma Foundation guidelines recommend intracranial pressure (ICP) monitoring in sTBI. We hypothesized that early ICP monitor placement was associated with better outcomes in children. Methods: This was a retrospective study of children with sTBI admitted to the participating pediatric intensive care units (PICUs) and entered into the Virtual Pediatric Systems (VPS), LLC, database between 1 January 2010 and 31 December 2015. We compared outcomes of patients who had an ICP monitor placed early (≤6 h from PICU admission) to those with later placement (> 6 to < 72 h). We collected demographics, diagnoses, procedure data, illness severity scores, outcomes, and site data. Multivariable regression analysis was used to identify variables independently associated with outcomes. Results: Twenty-seven percent of 3,608 patients with sTBI underwent ICP monitoring, 355 in the early and 156 in the later ICP monitoring groups, respectively. A higher proportion of patients in the early ICP monitoring group had worse markers of illness/injury severity; unadjusted analysis showed higher mortality in this group (31.3 vs. 21.8%, p = 0.029). Multivariable regression analysis showed that ICP monitoring was not independently associated with any of the outcomes. Conclusion: Time to ICP monitoring was not associated with outcomes after pediatric sTBI.
