Comparison of the effectiveness of bilateral ilioinguinal nerve block and wound infiltration for postoperative analgesia after caesarean section.

We have studied the effects of bilateral ilioinguinal nerve block and wound infiltration with 0.5% bupivacaine on postoperative pain and analgesic requirements in 62 patients undergoing Caesarean section under general anaesthesia. A control group received no local anaesthetic supplementation. Both ilioinguinal block and wound infiltration reduced significantly the pain scores and analgesic requirements in the immediate postoperative period (P < 0.05). The differences in pain scores and analgesic requirements between the study groups were not statistically significant (P > 0.05).
