IMPORTANCE: Preterm infants are at high risk of developing brain injury, and near-infrared spectroscopy (NIRS) offers the ability to measure cerebral oxygenation. The impact of using a standardized treatment guideline combined with a single NIRS device manufacturer (Nonin Medical Inc) and neonatal sensor on cerebral oxygenation has not been previously examined.
OBJECTIVE: To investigate whether cerebral oximetry with a dedicated treatment guideline improves cerebral oxygenation stability.
DESIGN, SETTING, AND PARTICIPANTS: This was a single-blinded, 2-arm randomized clinical trial conducted from October 2021 to July 2024 at 5 tertiary neonatal intensive care units across Australia, New Zealand, and the US. Infants born at less than 29 weeks' gestation and aged younger than 6 hours underwent 1:1 random allocation stratified by gestational age (<26 weeks and ≥26 weeks) and study site.
INTERVENTION: The intervention group received cerebral oximetry and dedicated guideline-based treatment when cerebral oxygenation was outside the range of 65% to 90%. The control group had blinded cerebral oximetry and treatment guided by standard clinical monitoring.
MAIN OUTCOMES AND MEASURES: The burden of cerebral hypoxia and hyperoxia during the first 5 days after birth expressed as percentage hours was the primary outcome. Key secondary outcomes were mortality, morbidities before discharge, and NIRS-related skin injury.
RESULTS: Of 149 screened infants (53 randomized to the intervention and 51 randomized to standard care), 100 infants were included in the final analysis (median [IQR] gestational age, 27 [25-28] weeks; 48 male [48.0%]). The median (IQR) birth weight was 883 (709-1079) g. The intervention group (50 infants) had a significantly lower median (IQR) burden of hypoxia and hyperoxia of 5.7% hours (2.8% hours to 15.0% hours) compared with 39.6% hours (6.5% hours to 82.3% hours) in the standard care group (50 infants), with an adjusted reduction of 42.8% hours (95% CI, 35.6% hours to 53.3% hours; P < .001). Mortality, morbidities before discharge, and safety outcomes were comparable between groups.
CONCLUSIONS AND RELEVANCE: In this study, treatment guided by cerebral oximetry with a single device manufacturer and a neonatal sensor significantly improved the stability of cerebral oxygenation in extremely preterm infants. Larger multicenter trials are warranted to determine if this finding leads to improved survival without brain injury.
