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 Comparative Study Clinical Trial
Comparison of effect of narcotic and epidural analgesia on postoperative respiratory function.
A prospective, randomized comparison was made of the value of meperidine versus epidural analgesia when used for the relief of pain after cholecystectomy in twenty patients without cardiopulmonary disease. Respiratory function was assessed the day before surgery and at 3 to 4 hours and 24 hours after operation by the bedside measurement of expiratory peak flow, vital capacity, and arterial blood gases. The two groups of patients were comparable as to age, height, weight, smoking habits, preoperative peak flow, vital capacity, and duration of operation. ⋯ However, at 3 to 4 hours postoperatively, vital capacity was significantly greater in the epidural anesthesia group. This might account for the differences in arterial blood gases the following day. These findings suggest that epidural analgesia is valuable in the early postoperative period after upper abdominal surgery.
