Acknowledging there are several perceived factors that contribute to unplanned extubations, a secondary objective was to describe how practice variation may relate to observed differences in unplanned extubation rates. A survey about practices related to the care of intubated patients was distributed to all pediatric intensive care units (PICUs) participating in the Virtual Pediatric Systems (VPS, LLC). Unplanned extubation rates for 2019 to 2020 were obtained from VPS. Univariate and bivariate analyses were performed to describe the responses, with unplanned extubation rates calculated as means. The text responses about perceived causes of unplanned extubation in participants' sites were explored using thematic content analysis. A total of 44 PICUs were included in this study (response rate 37.0%). The mean unplanned extubation rate for the sample was 0.41 (95% confidence interval: 0.31–0.50) per 100 intubation days. Variability was found across several aspects that impact care, including staffing, the frequency of procedures (e.g., chest radiography), and treatment-related goals (e.g., sedation and mobilization). The perceived causes of unplanned extubations in the sample included patient-, staff-, and equipment-related factors. We found practice variability in pediatric critical care units related to the care of intubated patients, which may contribute to the frequency of adverse events. As evidence emerges and professional associations and organizations recommend the best practices, knowledge translation will be required for the implementation and deimplementation of practices to improve the quality of care in PICUs.","PeriodicalId":44426,"journal":{"name":"Journal of Pediatric Intensive Care","volume":"11 1","pages":""},"PeriodicalIF":0.7,"publicationDate":"2022-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84893329","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 prospective cohort study included 59 patients who underwent mechanical ventilation in the pediatric intensive care unit of a tertiary care university hospital from July 2020 to June 2021. Each patient underwent laboratory testing including serum levels of thyroid-stimulating hormone (TSH), free T3 (fT3), free T4 (fT4), and reverse T3 (rT3) on the first and third days of mechanical ventilation. On the first day of mechanical ventilation, 62.7% of patients had low fT3, which significantly increased to 78% of patients on the third day. In comparison to values on day one, median levels of fT3 and fT4 significantly decreased and rT3 significantly increased on day three. However, no significant differences were found in the median TSH levels over the same time span. Thirty-five patients (59%) survived while 24 patients (41%) did not survive. Compared with survivors, non-survivors had significantly higher median serum TSH levels on day one, while all other thyroid function tests assays did not significantly differ between days one and three. Of note, serum TSH, fT3, fT4, and rT3 levels, on the first and third days, did not differ significantly between patients who experienced extubation failure and extubation success. To the best of our knowledge, this is the first study to examine thyroid function values in mechanically ventilated children to determine their correlation with extubation outcomes. In this study, NTIS did not correlate with extubation outcomes in critically ill children undergoing mechanical ventilation.","PeriodicalId":44426,"journal":{"name":"Journal of Pediatric Intensive Care","volume":"49 1","pages":""},"PeriodicalIF":0.7,"publicationDate":"2022-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77398146","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 systematic review consisted of searching PubMed, Scopus, Google Scholar, Cochrane Database of Systematic Reviews, and references of journals using pre-trialed MeSH terms and articles. Eight studies were included for full text analysis from 2,369 initial articles: six retrospective reviews and two prospective studies. Rate of complication was 8.6% and all complications were ischemic in nature. Complications most often occurred in neonates with pulmonary/cardiac comorbidities and lower gestational ages. No association was found for weight and sex of neonates. The radial artery site presented with lower rates of complication of 6% and the femoral presented with the highest (16%). Complications predominately occurred in catheter sizes larger than 22 gauge and most often within 1 day of insertion. A low rate of complications (7.4%) was observed in studies that used heparinized saline at the time of catheterization. This study demonstrates an increasing overall rate of complications with ischemia presenting as the most common complication. There seems to be an association between gestational age, comorbidities, site of catheter, size of catheter, and duration of catheter with such complications. This study also demonstrates the association between the use of heparinized saline and a reduction in rate of complications. The authors advocate for a national data collection tool of all pediatric arterial catheters and its complications to be able to analyze and work on best practice to minimize life changing iatrogenic complications.","PeriodicalId":44426,"journal":{"name":"Journal of Pediatric Intensive Care","volume":"59 11-12","pages":""},"PeriodicalIF":0.7,"publicationDate":"2022-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72606547","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 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.

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.

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.
