ReviewPostoperative analgesia. Use of intrathecal morphine in children.
The identification of opiate receptors in the spinal cord gave rise to the suggestion that the use of intrathecal and epidural narcotics may provide effective and safe postoperative analgesia. The authors retrospectively reviewed the records of ten children who received intrathecal morphine as part of their anesthetic care over the last 2 years. Preservative-free morphine (Duramorph) in a dose of 0.02 mg/kg was administered to all patients in the lumbar intrathecal space before the start of the surgical procedure. ⋯ As with narcotics administered by any route, intrathecal morphine can cause respiratory depression, and such depression may be delayed for up to 24 hours after the dose. Therefore, the postoperative respiratory status of these children should be monitored for 24 hours after the dose, preferably in an intensive care unit. With this caveat, the use of intrathecal morphine provides safe and effective postoperative analgesia in children undergoing major surgery.

Randomized Controlled Trial Comparative Study Clinical Trial Controlled Clinical Trial[Analgesic and respiratory effects of nalbuphine during the immediate postoperative period in thoracotomy].
As most patients undergoing pulmonary surgery by postero-lateral thoracotomy have decreased preoperative pulmonary function, efficient postoperative analgesia is mandatory. Nalbuphine, a new agonist-antagonist opioid analgesic, and nefopam were compared in a double blind trial involving 60 patients. Intravenous injections of 0.3 mg.kg-1 of either drug were started when the patient evaluated his pain as being above 60 mm on a visual scale graduated from 0 to 100 mm. ⋯ Nefopam led to a 30% increase in heart rate for one hour (p less than 0.01). Whereas patients given nalbuphine were more drowsy, although easily aroused, (p less than 0.001), nefopam was responsible for adverse effects (sweating, nausea, tachycardia with pallor, vertigo, malaise) requiring the exclusion of 7 patients from the study. Nalbuphine, although not ideal, would therefore seem to be a better analgesic than nefopam in thoracotomy patients.

Randomized Controlled Trial Clinical TrialEpidural and intravenous fentanyl infusions are clinically equivalent after knee surgery.
The management of postoperative pain with continuous epidural fentanyl infusion was compared with continuous intravenous fentanyl infusion. In a randomized, doubleblind protocol we prospectively studied 20 patients undergoing repair of the anterior cruciate ligament of the knee. The quality of analgesia and the incidence of side effects were documented. ⋯ There were no significant differences in the incidence of nausea, pruritus, or urinary retention. There was no respiratory depression in either group. We conclude that when compared with continuous intravenous fentanyl infusion, continuous epidural fentanyl infusion offers no clinical advantages for the management of postoperative pain after knee surgery.

Adequate pain relief during the postoperative period has long been recognized as difficult to accomplish. The reasons for this are mentioned in a brief review of methods of pain control, and an overview of the detrimental effects of acute pain is given. ⋯ It was also noted that only 30-35% of the maximum doses of analgesics prescribed were actually given within the immediate postoperative period. The possible reasons for these findings are discussed.

Randomized Controlled Trial Comparative Study Clinical TrialA comparison of postoperative pain relief techniques in orchidopexy.
Fifty consecutive patients admitted to the Western General Hospital for orchidopexy, were randomly allocated to receive either a caudal bupivacaine block or peroperative wound instillation with bupivacaine, to provide postoperative analgesia. Bupivacaine wound instillation reduced the total operating time, gave more efficient postoperative pain relief in hospital and proved both inexpensive and simple in its application.
