【 摘 要 】

Background: According to recommendations, non-invasive monitoring during neonatal resuscitation after birth includes heart rate (HR) and oxygen saturation (SpO 2 ). Continuous transcutaneous monitoring of carbon dioxide partial pressure (tcpCO 2 ) may further offer quantitative information on neonatal respiratory status. Objective: We aimed to investigate feasibility of tcpCO 2 measurements in the delivery room during immediate neonatal transition and to compare the course of tcpCO 2 between stable term and preterm infants. Methods: Neonates without need for cardio-respiratory intervention during immediate transition after birth were enrolled in a prospective observational study. In these term and preterm neonates, we measured HR and SpO 2 by pulse oximetry on the right wrist and tcpCO 2 with the sensor applied on the left hemithorax during the first 15 min after birth. Courses of tcpCO 2 were analyzed in term and preterm neonates and groups were compared. Results: Fifty-three term (gestational age: 38.8 ± 0.9 weeks) and 13 preterm neonates (gestational age: 34.1 ± 1.5 weeks) were included. First tcpCO 2 values were achieved in both groups at minute 4 after birth, which reached a stable plateau after the equilibration phase at minute 9. Mean tcpCO 2 values 15 min after birth were 46.2 (95% CI 34.5–57.8) mmHg in term neonates and 48.5 (95%CI 43.0–54.1) mmHg in preterm neonates. Preterm and term infants did not show significant differences in the tcpCO 2 values at any time point. Conclusion: This study demonstrates that tcpCO 2 measurement is feasible during immediate neonatal transition after birth and that tcpCO 2 values were comparable in stable term and preterm neonates.
