Article Abstract

Unlabelled: Pediatric ventilation liberation has limited evidence, likely resulting in wide practice variation. To inform future work, practice patterns must first be described.

Objectives: Describe international pediatric ventilation liberation practices and regional practice variation.

Design Setting And Participants: International cross-sectional electronic survey. Nontrainee pediatric medical and cardiac critical care physicians.

Main Outcomes And Measures: Practices focusing on spontaneous breathing trial (SBT) eligibility, SBT practice, non-SBT extubation readiness bundle elements, and post-extubation respiratory support.

Results: Five-hundred fifty-five responses representing 47 countries were analyzed. Most respondents reported weaning followed by an SBT (86.4%). The top SBT eligibility variables reported were positive end-expiratory pressure (95%), Fio (93.4%), and peak inspiratory pressure (73.9%). Most reported use of standardized pressure support regardless of endotracheal tube size (40.4%) with +10 cm HO predominating (38.6%). SBT durations included less than or equal to 30 minutes (34.8%), 31 minutes to 1 hour (39.3%), and greater than 1 hours (26%). In assigning an SBT result, top variables were respiratory rate (94%), oxygen saturation (89.3%), and subjective work of breathing (79.8%). Most reported frequent consideration of endotracheal secretion burden (81.3%), standardized pain/sedation measurement (72.8%), fluid balance (83%), and the endotracheal air leak test as a part of extubation readiness bundles. Most reported using planned high flow nasal cannula in less than or equal to 50% of extubations (83.2%). Top subpopulations supported with planned HFNC were those with chronic lung disease (67.3%), exposed to invasive ventilation greater than 14 days (66.6%), and chronic critical illness (44.9%). Most reported using planned noninvasive ventilation (NIV) following less than or equal to 20% of extubations (79.9%). Top subpopulations supported with planned NIV were those with neuromuscular disease (72.8%), chronic lung disease (66.7%), and chronic NIV use for any reason (61.6%). Regional variation was high for most practices studied.

Conclusion And Relevance: International pediatric ventilation liberation practices are heterogeneous. Future study is needed to address key evidence gaps. Many practice differences were associated with respondent region, which must be considered in international study design.

Background: Dexamethasone 6 mg in patients with severe COVID-19 has been shown to decrease mortality and morbidity. The effects of higher doses of corticosteroid, that would further increase anti-inflammatory effects, are uncertain. The objective of our study was to assess the effect of 20 mg dexamethasone vs.

The Association of Red Blood Cell Transfusion with Mortality in Pediatric Patients with Sepsis, Severe Sepsis, and Septic Shock: a single-center retrospective cohort study.

Transfus Clin Biol

Department of Blood Transfusion, Children's Hospital, Zhejiang University School of Medicine, National Clinical Research Center for Child Health, Hangzhou, Zhejiang Province, P.R. China. Electronic address:

Background/objectives: Pediatric patients with sepsis are frequently subjected to red blood cell (RBC) transfusions but yet its association with mortality is still controversial.

Methods: We consecutively selected 125 patients with sepsis, severe sepsis, and septic shock admitted to intensive care unit (ICU) in our center from January 2022 to January 2023, and finally 100 patients were included in this retrospective cohort study. The patients were divided into two groups: group I who received RBC transfusion and group II who did not receive RBC transfusion.

An update on multiple breath washout in children with cystic fibrosis.

Expert Rev Respir Med

December 2024

Division of Respiratory Medicine, The Hospital for Sick Children, Toronto, Ontario, Canada.

Introduction: Cystic fibrosis (CF) is an autosomal recessive disorder caused by mutations in the CF transmembrane regulator (CFTR) gene, leading to progressive lung disease and systemic complications. Lung disease remains the primary cause of morbidity and mortality, making early detection of lung function decline crucial. The Lung Clearance Index (LCI), derived from the multiple breath washout (MBW) test, has emerged as a sensitive measure for identifying early airway disease.

Background: The treatments and outcomes of pediatric gastroduodenal perforations have rarely been described.

Methods: We retrospectively identified 515 patients aged 28 days to 17 years who were hospitalized for gastroduodenal perforation between July 2010 and March 2021 using a nationwide inpatient database. We compared characteristics, treatments, and outcomes for pediatric gastroduodenal perforation between children aged <7 years (n = 38) and ≥7 years (n = 477).

Article Synopsis
  • Tracheostomy tubes increase the risk of respiratory infections, and initial treatment often involves nebulized tobramycin, but there’s a lack of standardized treatment guidelines.
  • A study used a breathing simulator to test how much tobramycin reaches simulated children with tracheostomies, comparing delivery methods and doses for different child weights.
  • Results showed that jet nebulizers delivered significantly more tobramycin than vibrating mesh nebulizers, highlighting the need for better dosing strategies and further research on drug delivery efficiency and higher dosages for this patient group.
