When it comes to preterm infants, every second in the delivery room counts. Stabilization and resuscitation during those first critical minutes after birth can significantly influence long-term outcomes. Now, new evidence suggests that real-time monitoring of brain oxygenation using near-infrared spectroscopy (NIRS) could help guide these interventions and improve survival without brain injury.
A newly published systematic review and Bayesian meta-analysis has evaluated whether cerebral tissue oxygen saturation (CrSO₂) monitoring during neonatal resuscitation can make a meaningful difference in outcomes for preterm infants. This is the first meta-analysis to focus on how NIRS-guided interventions influence survival without cerebral injury in this vulnerable population.
What Was Studied?
Researchers performed a comprehensive literature search of databases including MEDLINE, EMBASE, CINAHL, Google Scholar, and Cochrane CENTRAL through December 2024. Only human studies that implemented CrSO₂ monitoring during neonatal resuscitation of infants born <34 weeks’ gestation were included. A Bayesian individual participant data (IPD) meta-analysis was conducted to rigorously assess outcomes.
Key Findings
Two high-quality randomized controlled trials involving 667 preterm infants were included.
Survival without cerebral injury was higher in infants who received NIRS-guided care compared to standard resuscitation:
NIRS group: 83.0% survival without cerebral injury (95% Credible Interval [CI]: 78.9–86.9%)
Control group: 78.5% (95% CI: 74.0–82.7%)
Mean difference: +4.5% (95% CI: -1.4% to +10.5%), with 93% probability of benefit.
Intraventricular hemorrhage (IVH) of any grade was also less frequent, with a 4.2% reduction and 94% probability of benefit in the NIRS group.
The risk of bias was low, enhancing confidence in the findings.
Why Does This Matter?
Preterm infants are at high risk of brain injury during the transition after birth. Intervening too late—or too aggressively—can have devastating consequences. NIRS offers a non-invasive window into the infant’s brain oxygenation, potentially allowing care teams to tailor resuscitative efforts in real-time. This review provides early but compelling evidence that this approach could improve neurodevelopmental outcomes.
Final Thoughts
With high confidence in benefit shown through Bayesian analysis, this review supports incorporating CrSO₂-guided monitoring into neonatal resuscitation protocols. While further studies are needed to confirm these findings and define best practices, the data suggest we may be entering a new era of precision resuscitation for preterm newborns.
