Objective: That they have insufficient immunity, mothers' immune system have an modulator impact to fetus; obstetrics anesthesia methods used is important. We investigated that the difference between different types of anesthesia on fetal IL-6 levels and NK cell activity in this study. Method: Thirty patients undergoing elective caesarean section were assigned to two groups: In Spinal Anesthesia Group (n:15), anesthesia was performed with hyperbaric bupivacaine and fentanyl. In General Anesthesia Group (n:15), induction was performed with thiopenthal, succinylcholine and sevoflurane. After clamping the umbilical cord, fentanyl and vecuronium were administered. Maternal blood was collected for IL-6 levels at preoperative period and final closure of the skin incision. After neonatal delivery, cord blood was collected for NK cell activity, IL-6 and Cortisol levels. Results: The time interval from the beginning of anaesthesia to umblical cord clamping (AbzKkz) was longer in spinal anaesthesia group (p<0.05) and there was negative correlation between this time and fetal IL-6 levels (p<0.05). Pre- postoperative maternal and fetal IL-6 levels were not influenced by anesthesia techniques (p>0.05). Fetal cortisol levels were higher in general anesthesia group (p<0.05). There was no difference between pre-and postoperative maternal IL-6 levels within groups (p>0.05). NK cell activity was smilar in both groups (p>0.05). There was negative correlation between NK cell activity and fetal IL-6 levels in general anesthesia group (p<0.05). Conclusion: Longer AbzKkz and its negatively correlation with fetal IL-6 level in spinal anesthesia group and higher fetal cortisol level in general anesthesia group may be important for fetal defense to stress and infection.
