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.

Randomized Controlled Trial Comparative Study Clinical Trial
Anaesthesia for surgical correction of fractured femoral neck. A comparison of three techniques.
Sixty patients with fractured neck of femur and scheduled for surgical correction were randomly allocated to receive one of three anaesthetic techniques: general anaesthesia; spinal analgesia; psoas compartment block. The patients in the local anaesthetic groups also received a light general anaesthetic. There was little difference in the pre-, intra- and postoperative events, and no difference in postoperative mortality.

Randomized Controlled Trial Comparative Study Clinical Trial
The neonatal neurobehavioral effects of bupivacaine, mepivacaine, and 2-chloroprocaine used for pudendal block.
The neonatal neurobehavioral effects of bupivacaine, mepivacaine, and 2-chloroprocaine used in random sequence for pudendal block anesthesia were studied. The neurobehavioral status of 54 infants was studied 4 and 24 hours after delivery. ⋯ Mean mepivacaine levels in neonatal capillary blood at 4 hours of age were low (0.10 +/- .02 microgram/ml) compared with those in previous studies because of the short interval between maternal injection and delivery (13 +/- 3 min). Bupivacaine gave higher neonatal capillary blood levels (0.15 microgram/ml at 4 hours of age) than previously reported, but the drug still produced no detectable neonatal neurobehavioral effects.

Randomized Controlled Trial Comparative Study Clinical Trial
Cryoanalgesia for post-thoracotomy pain.
Intercostal block by a freezing technique was compared with blockade by local anaesthetics or no blockade as a method of treating post-thoracotomy pain. The 15 patients who received cryotherapy had significantly less postoperative pain than the 9 patients whose nerves were blocked by local anaesthetics or who did not receive any nerve block. The interruption of nerve function produced by cryotherapy was temporary (not more than 30 days), and there were no adverse sequelae.

Randomized Controlled Trial Clinical Trial
Prospective randomized evaluation of intrathoracic intercostal nerve block with bupivacaine on postoperative ventilatory function.
This prospective and randomized study demonstrates the beneficial effect of intrathoracic intercostal block with bupivacaine on the recovery of pulmonary function after thoracotomy. A significantly (p less than 0.05) better forced expiratory volume was seen in the treated group in the early post-operative period. ⋯ Also, the requirements for analgesics were decreased in the treated group. We believe that intrathoracic intercostal block with bupivacaine when properly utilized can be a good adjuvant in the improvement of pulmonary function after thoracotomy.
