Intro

In this World Shared Practice Forum podcast, Dr. Mark Peters discusses the Oxy-PICU trial, published in The Lancet in January 2024, which compared conservative to liberal oxygenation targets in critically ill children. The study highlighted the importance of pragmatic trial design and the need for larger trials to confirm these findings. LEARNING OBJECTIVES -Discuss the background driving the investigation of oxygenation in critically ill children -Summarize the study design of the Oxy-PICU Trial -Present the outcomes and challenges of the Oxy-PICU Trial -Identify the key characteristics of pragmatic trial design and the implication of pragmatic trial results AUTHORS Mark Peters, MBChB, MRCP, FFICM, FRCPCH, PhD Professor of Paediatric Intensive Care NIHR Senior Investigator UCL Great Ormond St Institute of Child Health Hon.
