BACKGROUND: Currently, reliable reference values of regional cerebral oxygen saturation (rScO(2)) for different gestational age (GA) groups are lacking, which hampers the implementation of near-infrared spectroscopy (NIRS) alongside monitoring arterial oxygen saturation (SaO(2)) and blood pressure in neonatal intensive care. The aim of this study was to provide reference values for rScO(2) and cerebral fractional tissue oxygen extraction (cFTOE; (SaO(2)-rScO(2))/SaO(2)) for small adult and neonatal NIRS sensors. METHODS: In this study, 999 infants born preterm (GA <32 wk) were monitored with NIRS during the first 72h of life. Mixed modeling was used to generate reference curves grouped per 2 wk of GA. In addition, the influence of a hemodynamically significant patent ductus arteriosus, gender, and birth weight were explored. RESULTS: Average rScO(2) was similar to 65% at admission, increased with GA (1% per week) and followed a parabolic curve in relation to postnatal age with a peak at similar to 36 h. The cFTOE showed similar but inverse effects. On average, the neonatal sensor measured 10% higher than the adult sensor. CONCLUSION: rScO(2) and cFTOE reference curves are provided for the first 72 h of life in preterm infants, which might support the broader implementation of NIRS in neonatal intensive care.
