Randomized Controlled Trial Comparative Study Clinical Trial Controlled Clinical TrialEpidural sufentanil for intra- and postoperative analgesia in thoracic surgery: a comparative study with intravenous sufentanil.
A comparative study was undertaken to evaluate the effectiveness of epidural sufentanil in providing intra- and postoperative analgesia during thoracic surgery. Sufentanil was chosen on the basis of its high lipid solubility and its potent opiate receptor binding. Epidural sufentanil was compared with intravenous sufentanil as the major intraoperative analgetic agent in an anesthesia regimen with midazolam and nitrous oxide. ⋯ Sufentanil provided good analgesia with a very fast onset and a mean duration of almost 7 h. Severe respiratory depression was observed in one patient within 1 h of extubation, probably due to the combined effects of the narcotic administration and residual midazolam. It is concluded that 50 micrograms of sufentanil administered in the thoracic epidural space provides valuable intraoperative analgesia which can easily be extended into the postoperative period, although all necessary precautions for epidural opiate administration should be taken.

Randomized Controlled Trial Comparative Study Clinical Trial
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. ⋯ 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.

Comparative Study Clinical Trial Controlled Clinical Trial
Pharmacokinetics and clinical efficacy of intrarectal solution of acetaminophen.
Acetaminophen is frequently administered orally to children for its analgesic properties, although its potency has never been clearly evaluated in this population. In certain situations (patients vomiting or unconscious), acetaminophen has to be given rectally. However, the rectal absorption of suppositories is frequently erratic. ⋯ The absorption of acetaminophen was incomplete (peak serum concentration: 70.8 mumol. L-1) and delayed. We conclude that the rectal administration of acetaminophen at the induction of anesthesia results in incomplete and delayed absorption and does not prevent the occurrence of immediate postoperative pain in children undergoing adeno-tonsillectomy.
