Comparison of visceral pain incidence during cesarean section performed under spinal or epidural anesthesia.

The incidence of visceral pain during cesarean section performed under regional anesthesia was studied in 80 unpremedicated patients. They were divided in two similar groups concerning age, weight and height. Group 1 consisted of 40 patients submitted to cesarean section under spinal anesthesia, while in group 2 (40 patients) epidural anesthesia was used. Surgery was totally painless for all patients of group 1 patients, whereas in group 2 intraoperative analgesia was complete for 11, good in 18 and fair in 10 patients. One patient of group 2 required general anesthesia due to excrutiating pain during exteriorization of uterus despite a seemly adequate lebel of cutaneous analgesia of T(6). The authors conclude that spinal anesthesia favorably compares with epidural anesthesia for cesarean section, because the incidence of visceral pain with the former was nill and because both techniques are equally safe for mothers and neonates.
