Meta-analysis of Oxygenation Saturation Targeting Trials: Do Infant Subgroups Matter?

Area of Science:

• Neonatal Medicine
• Pediatric Critical Care
• Respiratory Physiology

Background:

• Extremely preterm infants require precise oxygen management to minimize mortality and morbidity.
• Existing oxygen saturation guidelines vary, necessitating evidence-based policy refinement.
• Retinopathy of prematurity (ROP) is a significant concern in preterm infants requiring supplemental oxygen.

Purpose of the Study:

• To meta-analyze participant data from approximately 5000 infants to guide oxygen saturation policy for extremely preterm infants.
• To compare outcomes associated with higher versus lower oxygen saturation targeting ranges.
• To evaluate the impact on death, necrotizing enterocolitis, major disability, and ROP.

Main Methods:

• Meta-analysis of participant data from approximately 5000 infants.
• Utilized data from the Neonatal Oxygenation Prospective Meta-analysis (NOPM).
• Compared clinical outcomes between higher and lower target oxygen saturation ranges.

Main Results:

• Targeting a higher oxygen saturation range (91%-95%) decreased death and necrotizing enterocolitis.
• No significant difference in major disability was observed between groups.
• Increased rates of treated retinopathy of prematurity (ROP) and supplemental oxygen use at 36 weeks' postmenstrual age were noted with higher ranges.

Conclusions:

• A 91%-95% oxygen saturation range can be recommended for extremely preterm infants from birth.
• Stringent surveillance for ROP prevention and early treatment is crucial when using this higher range.
• Balancing the benefits of reduced mortality with the risks of ROP is essential for optimal infant care.
