Randomized Controlled Trial Comparative Study Clinical TrialEpidural morphine for postoperative pain relief: a comparative study with intramuscular narcotic and intercostal nerve block.
The relatively new technique of epidural morphine analgesia was compared with two well established method of pain relief in 90 patients undergoing gallbladder surgery and divided randomly into three groups of 30 patients each. The first group received intramuscular narcotic analgesic ketobemidone, the second group was given 0.5% bupivacaine-epinephrine intercostal nerve block, and the third group received a single dose of 4 mg of epidural morphine for postoperative pain relief. The mean duration of analgesia after ketobemidone was 5.5 hours, and after intercostal block 11 hours. ⋯ Delayed respiratory depression was not encountered after epidural morphine. It is concluded that a single dose of 4 mg of epidural morphine provides excellent regional analgesia of long duration without drowsiness or circulatory of respiratory depression thus facilitating early ambulation. The technique is superior to more common methods of pain relief after gallbladder surgery, e.g., intercostal nerve block and intramuscular narcotics.

Randomized Controlled Trial Clinical Trial
Intercostal nerve block with thoracoabdominal and flank incisions.
A double-blind study was done in 90 patients undergoing a rib-resecting thoracoabdominal incision for testicular cancer or a flank incision for renal surgery to determine the effect of intraoperative intercostal nerve block with bupivacaine hydrochloride on postoperative pain and complications, day of ambulation, and day of oral fluid intake. In the patients treated with bupivacaine, we found a significant reduction in the amount of postoperative analgesia required, but no difference in the day of ambulation or fluid intake. Ten of 45 patients given a placebo nerve block experienced postoperative atelectasis, whereas only 4 of 45 patients in the treated group experienced this complication. We believe that intercostal nerve block is a valuable postoperative adjuvant in patients undergoing flank surgery to reduce the postoperative analgesic requirements and incidence of atelectasis.

A technique of continuous axillary brachial plexus block, using an epidural Tuohy needle and an epidural catheter, is described. Studies were carried out in ten patients using this technique with bupivacaine as a local anesthetic drug. ⋯ Good analgesia was obtained in nine out of the ten patients. Thus this technique allows pain-free postoperative period in hand surgery.
