, , , , , , , , To identify predictive factors for failure in the installation of high-flow nasal cannulas in children diagnosed with acute viral bronchiolitis under 24 months of age admitted to the pediatric intensive care unit.
This work was a retrospective single-center cohort study conducted from March 2018 to July 2023 involving infants under 24 months of age who were diagnosed with acute viral bronchiolitis and who received high-flow nasal cannulas upon admission to the pediatric intensive care unit. Patients were categorized into two groups, the Success Group and Failure Group, on the basis of high-flow nasal cannula therapy efficacy. The primary outcome was treatment failure, which was defined as the transition to invasive or noninvasive ventilation. The analyzed variables included age, sex, weight, high-flow nasal cannula parameters, vital signs, risk factors, comorbidities, and imaging. Acute viral bronchiolitis severity was assessed using the Wood-Downes Scale, and functional status was assessed via the Functional Status Scale, both of which were administered by trained physiotherapists.
In total, 162 infants with acute viral bronchiolitis used high-flow nasal cannulas, with 17.28% experiencing treatment failure. The significant differences between the Failure and Success Groups included age (p = 0.001), weight (p = 0.002), bronchiolitis severity (p = 0.004), initial high-flow nasal cannula flow (p = 0.001), and duration of use (p = 0.000). The cutoff values for initial flow (≤ 12L/min), weight (≤ 5kg), and Wood-Downes score (≥ 9 points) were determined from the ROC curves. Initial flow ≤ 12L/min was the most predictive for failure (AUC = 0.71; 95%CI: 0.61 - 0.84; p = 0.001). Multivariate analysis indicated that weight was a protective factor (RR = 0.87; 95%CI: 0.78 - 0.98), duration of use reduced the risk of failure (RR = 0.49; 95%CI: 0.38 - 0.64; p = 0.000), and Wood-Downes score was not significant (RR = 1.04; 95%CI: 0.95 - 1.14; p = 0.427). Weight explained 84.7% of the variation in initial flow.
Risk factors for high-flow nasal cannula therapy failure in bronchiolitis patients include younger age, consequently lower weight, and a lower initial flow rate.

To compare the prevalence of malnutrition during two time periods in a pediatric intensive care unit.
This was a retrospective cross-sectional study of patients admitted to the pediatric intensive care unit of a university hospital during two one-year periods with an interval of four years between them. Nutritional evaluation was conducted based on weight and height measured at admission. The body mass index-for-age was the parameter chosen to evaluate nutritional status, as classified according to the World Health Organization, according to age group.
The total sample size was 881 (406 in the contemporary sample and 475 in the historical sample). There was a significant reduction in malnutrition in the contemporary sample (p = 0.03). Malnourishment in patients in the historical sample was significantly associated with mortality and length of stay, while malnourishment in patients in the contemporary sample was not associated with worse outcomes.
There was a significant reduction in malnutrition among patients in the same pediatric intensive care unit when comparing the two time periods. Our findings of a change in nutritional profile in critically ill patients corroborate the nutritional status data of children and adolescents worldwide.

BACKGROUND AND OBJECTIVES: To analyze and discuss the medical aspects related to the family involvement in the decision making process regarding end of life care to children admitted to the pediatric intensive care unit (PICU). CONTENTS: The authors selected articles on end-of-life care published during the last years searching the PubMed, MedLine and LILACS database, with special interest on studies of death conducted in pediatric intensive care units in Brazil, Latin America, Europe and North America, using the following keywords: death, bioethics, PICU, decision-making, terminal care, parents interview and life support limitation (LSL). CONCLUSIONS: Several studies have demonstrated the relevance of the family participation in the decision making process regarding LSL. In our region the family participation in this process is not stimulated and valued, ranging from 20%-55%. The authors present a practical sequence for discussing and defining LSL with the families. Despite of the family participation in the decision making process for LSL be legally, morally and ethically accepted in developed countries, this approach is adopted in a very few cases in our region. To explain this difficulty observed among the Brazilian pediatric intensivist, some studies should be conducted in our region.
