• Randomization to a Liberal Versus Conservative Oxygenation Target: Redox Responses in Critically Ill Children

    2 monthes ago - By Pediatric Critical Care Medicine

    Rationale:
    Optimal systemic oxygenation targets in pediatric critical illness are unknown. A U-shaped relationship exists between blood oxygen levels and PICU mortality. Redox stress or iatrogenic injury from intensive treatments are potential mechanisms of harm from hyperoxia.
    Objectives:
    To measure biomarkers of oxidative status in children admitted to PICU and randomized to conservative (oxygen-hemoglobin saturation 88-92%) versus liberal peripheral oxygenation targets.
    Design:
    Mechanistic substudy nested within the Oxygen in PICU pilot randomized feasibility clinical trial...
