Forty-five patients undergoing total abdominal hysterectomy were randomly divided into three groups. An epidural tube was inserted into one of the following three sites, Th11-12, L2-3, and caudal region. General anesthesia was then maintained with nitrous oxide-oxygen-enflurane, and pancuronium bromide. Morphine hydrochloride 2 mg in 8 ml of normal saline was administered into one of the designated epidural spaces one to two hours before the assumed end of surgery. Postoperative pain was assessed every four hours after the end of the operation until the next morning. Morphine exerted a relatively profound and prolonged analgesic effect in 40% of the Th11-12 group of patients, as well as in 6.7% of the L2-3 and caudal groups. But, supplementary analgesics were necessary in the other patients. No significant differences were found in the degree and extension of postoperative pain, as well as the doses of supplementary analgesics among the three groups. Adverse effects, such as nausea, vomiting and itching, occurred in 30 to 40% of each of the morphine administered groups. Though morphine was applied into different spinal levels, this clinical study did not show any difference in extension of analgesia. The epidurally applied morphine may be distributed widely in the spinal arachnoid space after some time, and may exert an effect on the brain as well as on the spinal nerves. When morphine is administered epidurally one to two hours before the end of a surgical operation, selection of an injection site according to the dermatome level of the skin incision may be unnecessary.

Postoperative nausea, vomiting and pain were compared between laparoscopic cholecystectomy group and minilaparotomy-cholecystectomy group. All patients were women, and ranged in age from 20 to 60 years. The body mass index of the patients was less than 30, and duration of operation was within 120 minutes in both groups. All patients received general anesthesia combined with epidural analgesia. Morphine hydrochloride 4 mg was administered into epidural space before incision. No significant differences were found in the incident of nausea and vomiting among the two groups. Postoperative analgesic requirement of laparoscopic cholecystectomy group was significantly less than that of minilaparotomy-cholecystectomy group. No significant differences were found in the incidence of nausea and vomiting between the group which required postoperative analgesic drugs and the group which required no postoperative analgesic drugs. These results suggest that laparoscopic operation and postoperative pain do not influence the incidence of nausea and vomiting. Postoperative pain after laparoscopic cholecystectomy is less than that after minilaparotomy-cholecystectomy.
