Recent evidence shows poor retention of Pediatric Advanced Life Support provider skills. Frequent refresher training and in situ simulation are promising interventions. We developed a "Pediatric Support-reconstructed" recertification course by deconstructing the into six 30-minute scenario sessions delivered over 6 months. hypothesized that Support-reconstructed implementation is feasible as effective standard recertification.A prospective randomized, single-blinded trial.Single-center,...

Bronchoalveolar lavage fluid (BALF) is considered a sterile type specimen that suitable for detecting pathogens respiratory infections. The aim this study was to comprehensively identify causative using NGS BALF samples from immunocompetent pediatric patients with failure. Ten hospitalized failure were included. obtained acute phase used prepare DNA- and RNA-sequencing libraries. libraries...

Abstract Anticoagulant treatment of pediatric central venous catheter–related thromboembolism (CVC-VTE) has not been specifically evaluated. In EINSTEIN-Jr, 500 children with any VTE received rivaroxaban or standard anticoagulants. A predefined analysis the CVC-VTE cohort was performed. Children (age, birth to 17 years) were administered anticoagulants during 1-month (children <2 3-month (all other children) study period. Predefined outcomes recurrent VTE, change in thrombotic burden...

OBJECTIVES: Current resuscitation guidelines recommend target chest compression depth (CCd) of approximately 4cm for infants and 5cm children. Previous reports based on CT suggest these recommended CCd targets might be too deep younger Our aim was to examine measurements anterior-posterior diameter (APd) with a laser distance meter calculate in critically ill DESIGN: A retrospective descriptive study. SETTING: Single-center PICU, using data from May 2019 2022. PATIENTS: All children admitted...
