Özet

Objective: Determining fetal/neonatal well-being by monitoring physiological changes, evaluating oxygenation/alveolar ventilation and circulation/ perfusion, and the need for resuscitation are considered necessary during the fetal/neonatal transition period after delivery. This study aims to investigate the correlation between non-invasive methods oxygen saturation (SpO2 ), perfusion index (PI), and cord blood gas parameters during the postnatal transition in term or near-term infants delivered vaginally or with cesarean section. Methods: Sixty-four healthy term/near term infants were enrolled into this study. The blood gases of the umbilical artery (UA) and umbilical vein (UV) were analyzed in each case. SpO2 and PI were recorded with a pulse oximeter. Results: SpO2 and PI values of vaginal births were significantly higher than who were born with cesarean section. A significant correlation between PI and SpO2 values of both UA and UV was found in the vaginal birth group, while no correlation was found in the cesarean group. The trend of the PI was time-independent, and PI reached stability before SpO2 . Conclusion: Non-invasive PI and SpO2 measurements could be promising in monitoring the oxygenation and circulation of neonates during the postnatal transition period.
