Objective To determine if addition of perfusion index (PIx) to oxygen saturation (SpO2) screening improves detection of critical congenital heart disease (CCHD) with systemic outflow obstruction. Study Design We determined screening thresholds for PIx and applied these to a cohort of newborns with and without congenital heart disease (CHD). Results A total of 123 normal and 21 CHD newborns (including five with critical systemic outflow obstruction) were enrolled. Four of these five critical systemic obstruction subjects passed SpO2-based screen. Four out of these five subjects failed PIx-based screen. The sensitivity for detection of systemic obstruction CCHD when compared with healthy infants increased from 20% (95% confidence interval [CI]: 1–72%) with SpO2 screening alone to 80% (95% CI: 28–100%) with combined SpO2-PIx screen. However, 2.44% of normal infants failed PIx screen. Conclusion Addition of PIx to SpO2 screening may detect additional cases of CCHD and further research is necessary to come up with optimal screening thresholds.

Body temperature (BT) management remains a challenge in neonatal intensive care, especially during resuscitation after birth. Our aim is to analyze whether there is an association between the BT and cerebral and peripheral tissue oxygen saturation (crSO2/cTOI and prSO2), arterial oxygen saturation (SpO2), and heart rate (HR). The secondary outcome parameters of five prospective observational studies are analyzed. We include preterm and term neonates born by Caesarean section who received continuous pulse oximetry and near-infrared spectroscopy monitoring during the first 15 min, and a rectal BT measurement once in minute 15 after birth. Four-hundred seventeen term and 169 preterm neonates are included. The BT did not correlate with crSO2/cTOI and SpO2. The BT correlated with the HR in all neonates (ρ = 0.210, p < 0.001) and with prSO2 only in preterm neonates (ρ = −0.285, p = 0.020). The BT was lower in preterm compared to term infants (36.7 [36.4–37.0] vs. 36.8 [36.6–37.0], p = 0.001) and prevalence of hypothermia was higher in preterm neonates (29.5% vs. 12.0%, p < 0.001). To conclude, the BT did not correlate with SpO2 and crSO2/cTOI, however, there was a weak positive correlation between the BT and the HR in the whole cohort and a weak correlation between the BT and prSO2 only in preterm infants. Preterm neonates had a statistically lower BT and suffered significantly more often from hypothermia during postnatal transition.
