PURPOSE: This study aimed to assess whether different anesthetic techniques and oxytocin use applied during delivery affect transcutaneous bilirubin levels during the first 24 hours in neonates. METHODS: A total of 1,044 neonates delivered by either caesarian section (C/S) or normal vaginal delivery (NVD) were included in the study. They were classified into 5 groups as follows: group 1: born by C/S using general anesthesia, group 2: C/S using spinal anaesthesia, group 3: C/S using general anesthesia after failed spinal block, group 4: by NVD without anesthesia, and group 5: oxytocin-induced vaginal delivery without anesthesia. Transcutaneous total bilirubin levels (TBLs) were measured during the first 24 hours and on the fifth and eighth days of life and the levels in different groups were compared. RESULTS: The TBLs were significantly higher in neonates delivered by C/S using general anesthesia rather than spinal anesthesia (P < 0.001), and both groups had higher levels than those born by NVD without anesthesia (P≤0.001). However, the group receiving general anesthesia after failed spinal block was found to have the highest bilirubin level. Moreover, TBLs were significantly higher with the use of oxytocin (P≤0.001). CONCLUSIONS: C/S and general anesthesia adversely affect the bilirubin levels in neonates, and the use of oxytocin during vaginal delivery also increases TBLs in neonates.
