Abstract: | Recent work suggests that preoperative skin infiltration with local anesthetic may lead to reduced postoperative pain. We have studied this in a randomised, prospective, double-blind trial of 40 women having cesarean section under spinal anesthesia. After establishment of the spinal block, the incision line was infiltrated in 20 women with 30 ml 0.5% bupivacaine and in 20 with 30 ml normal saline. There was no difference in pain scores between the 2 groups on any of the 3 postoperative days, perhaps due to the high quality analgesia provided by supplemental subarachnoid morphine. |
