Conservative versus conventional oxygenation target in children admitted in PICU: a randomized controlled trial

Area of Science:

• Pediatric Critical Care Medicine
• Respiratory Support
• Oxygen Therapy

Background:

• Optimizing oxygen saturation targets in critically ill children is crucial for improving clinical outcomes.
• Previous research has not definitively established the optimal oxygen saturation range for pediatric intensive care.
• Understanding the impact of different oxygen saturation targets on mortality and morbidity is essential.

Purpose of the Study:

• To compare the clinical outcomes of conservative versus conventional oxygen saturation targets in critically ill children.
• To evaluate the safety and efficacy of lower oxygen saturation targets in pediatric respiratory support.

Main Methods:

• An open-label randomized controlled trial involving 178 children (1 month to 15 years) requiring respiratory support.
• Patients were randomized to conservative (SpO₂ 88-92%) or conventional (SpO₂ 94-99%) oxygen saturation targets.
• Primary outcome: composite of death and organ support at 30 days. Secondary outcomes included mortality, duration of support, length of stay, and oxidative stress markers.

Main Results:

• No significant difference in the composite outcome of death or organ support at 30 days between groups.
• Significantly shorter duration of respiratory support (4 vs. 6 days) and oxygen therapy (8 vs. 100 hours) in the conservative group.
• Similar mortality rates, organ support days, length of stay, and serum malondialdehyde levels between the conservative and conventional groups.

Conclusions:

• Conservative oxygen saturation targets (88-92%) are safe and effective in critically ill children, reducing the duration of respiratory and oxygen therapy.
• These findings suggest a potential benefit of conservative oxygen management in pediatric intensive care.
• Larger multicenter trials are warranted to confirm these results and further elucidate the optimal oxygen strategy.
