Ilioinguinal nerve block with 0.375% marcaine for postoperative pain relief in cesarean section

Bilateral ilioinguinal nerve block with local anesthetic drugs to treat postoperative pain in lower segment cesarean section (Pfannestiel incision) under general anesthesia had show profound effective by P. Bunting and I. McConachie. We used the same method but with lower concentration 0.375% marcaine 10 ml to each side in 12 patients. We compare the pain score and the requirement for pethidine intramuscular injection to 12 patients as control group. Pain score were less in the block patients within 8h after surgery, and total amount of pethidine given was 700 mg. In control group, the pain score were higher at the first 8 h than nerve block group during the study (p less than 0.05), and the total amount of pethidine requirement was 1250 mg. There were no observed adverse effect during the study.
