Transcutaneous electrical stimulation for postoperative pain.

Abstract

A prospective randomised trial was conducted to assess transcutaneous electrical stimulation in the management of postoperative pain and its effect on postoperative pulmonary function and respiratory complications. Consecutive patients undergoing abdominal surgery were allocated to receive transcutaneous electrical stimulation or 'sham' therapy. There was no significant difference in the amount of postoperative pain as measured by linear analogue pain scales or morphine requirements. Arterial oxygen and carbon dioxide tensions were similar in both groups. There was no difference in the incidence of postoperative chest infection. These results do not support the use of transcutaneous electrical stimulation following abdominal surgery.
