ABSTRACT
Background: Caesarean delivery can be associated with considerable postoperative pain. This study designed to evaluate the efficacy
of ilioinguinal and iliohypogastric (II-IH) blocks on postoperative pain relief and use of opioids after lower segment caesarean
section. Materials and Methods: One hundred fifty mothers candidate for elective cesarean section (CS) included in the study and
randomly allocated into two groups. Procedure of CS was equal in all cases. group I were assigned randomly to receive nerve block
with either 20ml of 0.25% bupivacaine and in group II 20ml normal saline solution. Opioids dose was measured during the
postoperative period during 8 hours. Postoperative pain was assessed with a visual analog scale (VAS). Results: II-IH nerve blocks
with bupivacaine injection in CS may cause reduction of postoperative pain and analgesic consumption after CS. There was a
significant decrease in opioid administration and pain on visual analog scale in nerve block group, as compared with placebo Group.
8 hours after the operation, pain severity in both nerve blocks and placebo groups were similar. Total dose of opioid administration
was significantly lower in group I. Conclusion: This study shows that nerve blocks with bupivacaine injection in CS may cause
reduction of postoperative pain in mothers.
