Transcutaneous electrical nerve stimulation after thoracotomy . Pain relief and peak expiratory flow rate -- a trial of transcutaneous electrical nerve stimulation . Forty patients scheduled to undergo thoracotomy were randomly allocated to receive either transcutaneous electrical nerve stimulation with intramuscular papaveretum ( 20 patients ) or intramuscular papaveretum alone ( 20 patients ) for postoperative pain relief . Total intramuscular analgesic requirements in the first 24 hours , time to satisfactory transfer to oral analgesia , antiemetic requirements and length of stay in hospital postoperatively were noted . Peak expiratory flow rate was compared pre- and postoperatively in the two groups . Use of nerve stimulation did not significantly alter the requirements for analgesia although there was a reduction in postoperative nausea and vomiting in the nerve stimulation group . There was no difference between the two groups with respect to changes in peak expiratory flow rate .
