The new onset of refractory status epilepticus has rarely been described as the presenting feature of MIS-C. This retrospective study, conducted at Dr. B.C. Roy Post Graduate Institute of Pediatric Sciences, included children hospitalized between August 1, 2020 and July 31, 2021, with new-onset refractory status epilepticus (NORSE) and subsequently diagnosed to have MIS-C. Their clinico-demographic variables, treatment courses during hospital stays, laboratory reports, radiological and electrophysiological findings, and outcomes at discharge and follow-up over 1 year were recorded. At their 12 month visits, their motor disabilities (primary) and continuation of anti-epileptic drugs, and persistence of magnetic resonance imaging (MRI) brain abnormalities (secondary) were the outcome measures. The characteristics of the patients in the para-infectious and post-infectious groups were compared using the Mann-Whitney U test for continuous variables and the Chi-square test for categorical variables. There were eight and 10 patients in groups A and B, respectively. Patients in group B had significantly higher age, more prolonged refractory status epilepticus (RSE), use of anesthetics and ventilation, and longer pediatric intensive care unit (PICU) stay, while other clinical and laboratory parameters and short and long-term outcomes were not significantly different between the two groups. Eight patients developed hemiparesis, while two had quadriparesis in the acute stage, but 15 (83%) patients had complete recovery from their motor deficits by 1 year. At 1-year follow-up, 33 and 39% of patients, respectively, had abnormal MRI and electroencephalogram (EEG). Acute disseminated encephalitis and acute leukoencephalopathy were the most commonly observed MRI abnormalities in the acute phase, with prolonged persistence of cerebritis in patients in the post-infectious group, warranting long-term immunomodulation. Combined immunotherapy with intravenous immunoglobulin and steroids was effective in the acute phase. However, long-term anti-epileptic therapy was needed in both groups.","PeriodicalId":44426,"journal":{"name":"Journal of Pediatric Intensive Care","volume":null,"pages":null},"PeriodicalIF":0.7,"publicationDate":"2022-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86549239","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A composite teamwork score was generated using the average of each of five (7-point Likert scale) domains in the teamwork assessment tool. Poor teamwork was defined as an average score of 4 or lower. Team provider stress data were also recorded with each intubation. A total of 12,536 TIs were reported from 2013 to 2018. Approximately 4.1% (n = 520) rated a poor teamwork score. TIs indicated for shock were more commonly associated with a poor teamwork score, while those indicated for procedures and those utilizing neuromuscular blockade were less commonly associated with a poor teamwork score.

The goal of the study was to see how well the Pediatric Early Warning Sign (PEWS) score predicted the outcome of pediatric intensive care unit patients. This prospective cross-sectional study included children younger than 18 years. PEWS was calculated at presentation. The outcomes analyzed were mortality (primary outcome), need for mechanical ventilation, inotropic support, and length of stay (LOS). A median score was calculated and compared across the outcome groups. The performance of the PEWS was assessed for calibration and discrimination, and the best cutoff was determined. This study included 237 patients with a median score of 6 (range 4–9). Twenty-two (9.3%) patients required ventilator support and 66 (26.6%) inotropic support. The overall mortality rate was 5.1%, and 16.4% had prolonged LOS (>4 days). The median score of patients was significantly higher among those who died (8.5 vs. 6; p  = 0.001), required ventilator support (8 vs. 6; p  = 0.001), inotropic support (7 vs. 6; p  = 0.030), and prolonged LOS (7 vs. 6; p  = 0.001). On calibration, PEWS was found to have a good fit to predict mortality, the need for ventilator support, inotropic support, and prolonged LOS. Receiver operating characteristic curves for the PEWS model yield an area under the curve of 0.966 for mortality, 0.951 for ventilator support, 0.626 for inotropic support, and 0.760 for prolonged LOS. A cutoff value of > 7 was found to be the best to predict the outcome. PEWS is a robust tool to easily prognosticate the patient on the basis of clinical parameters.","PeriodicalId":44426,"journal":{"name":"Journal of Pediatric Intensive Care","volume":null,"pages":null},"PeriodicalIF":0.7,"publicationDate":"2022-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86744881","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aim of this study was to compare the use of cuffed and uncuffed ETTs in neonates in the neonatal intensive care unit of a tertiary children's hospital, assessing the presence of airway complications. We performed a single-center retrospective cohort study. Our study included all term neonates receiving cuffed ETTs over the period from January 2019 to December 2021. The controls were all neonates receiving an uncuffed ETT over the same period. Twenty-five patients were intubated with cuffed ETTs in the study period. The group receiving cuffed ETTs was compared with 53 patients receiving uncuffed ETTs. All cuffed ETTs were inserted in the operating room by anesthesiologists. Comparing the outcomes of the cuffed ETT group with controls, there were no significant differences in the number of unplanned extubations, reintubation episodes, ventilator-associated pneumonia, episodes of atelectasis, the use of dexamethasone, or vocal cord paresis. No unplanned extubation was observed in the cuffed ETT group, and no cases of subglottic stenosis were observed in either of the groups. This retrospective study with a small sample size suggests that the use of cuffed ETTs in surgical patients >2,000 g in weight is not associated with an increase in airway complications. Well-designed randomized controlled trials are needed to compare cuffed ETTs with uncuffed ETTs.","PeriodicalId":44426,"journal":{"name":"Journal of Pediatric Intensive Care","volume":null,"pages":null},"PeriodicalIF":0.7,"publicationDate":"2022-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83437044","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Traditional CPAP interfaces have been associated with inadequate seal, mucocutaneous injury, and aerosolization of infectious particles. The helmet interface may be advantageous given its ability to create a complete seal, avoid skin breakdown, and decrease aerosolization of viruses. We aim to measure tolerability and safety in a pediatric population in the United States and ascertain feedback from parents and health care providers. We performed a prospective, open-label, single-armed feasibility study to assess tolerability and safety of helmet CPAP. Pediatric patients 1 month to 5 years of age admitted to the pediatric intensive care unit with pulmonary infections who were on CPAP for at least 2 hours were eligible. The primary outcome was percentage of patients tolerating helmet CPAP for 4 hours. Secondary measures included the rate of adverse events and change in vital signs. Qualitative feedback was obtained from families, nurses, and respiratory therapists. Five patients were enrolled and 100% tolerated helmet CPAP the full 4-hour study period. No adverse events or significant vital sign changes were observed. All family members preferred to continue the helmet interface, nursing staff noted it made cares easier, and respiratory therapists felt the set up was easy. Helmet CPAP in pediatric patients is well-tolerated, safe, and accepted by medical staff and families in the United States future randomized controlled trials measuring its effectiveness compared with traditional CPAP interfaces are needed.","PeriodicalId":44426,"journal":{"name":"Journal of Pediatric Intensive Care","volume":null,"pages":null},"PeriodicalIF":0.7,"publicationDate":"2022-09-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73090023","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This is a prospective observational cohort study in a tertiary academic PICU. Children admitted to the PICU ≤24 hours after moderate or severe TBI were included in the study. Children suspected of being brain dead at PICU entry or with a pacemaker were excluded. Children underwent continuous monitoring of electrocardiographic (ECG) waveforms over 7 days post-TBI. HRV analysis was performed retrospectively, using a standardized, validated HRV analysis software (CIMVA). The occurrence of medical complications (“event”: intracranial hypertension, cerebral hypoperfusion, seizure, and cardiac arrest) was prospectively documented. Outcome of children 6 months post-TBI was assessed using the Glasgow Outcome Scale – Extended Pediatric (GOS-E Peds). Fifteen patients were included over a 20-month period. Thirteen patients had ECG recordings available and 4 had >20% of missing ECG data. When ECG was available, HRV calculation was feasible (average 88%; range 70–97%). Significant decrease in overall HRV coefficient of variation and Poincaré SD2 ( p  < 0.05) at 6 hours post–PICU admission was associated with an unfavorable outcome (defined as GOS-E Peds ≥ 3, or a deterioration of ≥2 points over baseline score). Several HRV metrics exhibited significant and nonsignificant variation in HRV during event. This study demonstrates that it is feasible to monitor HRV in the PICU provided ECG data are available; however, missing ECG data are not uncommon. These preliminary data suggest that altered HRV is associated with unfavorable neurological outcome and in-hospital medical complications. Larger prospective studies are needed to confirm these findings and to explore if HRV offers reliable and clinically useful prediction data that may help clinical decision making.","PeriodicalId":44426,"journal":{"name":"Journal of Pediatric Intensive Care","volume":null,"pages":null},"PeriodicalIF":0.7,"publicationDate":"2022-09-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76165298","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
