Randomized Controlled Trial Clinical TrialTransdermal fentanyl in postoperative pain.
The aim of this study was to determine the safety and effectiveness of a transdermal fentanyl delivery system for the relief of pain following abdominal surgery. ⋯ Similar postoperative analgesia was achieved with less parenteral analgesics in patients who received transdermal fentanyl preoperatively than in control patients. Fentanyl, 50-75 micrograms/h, administered in a transdermal delivery system, did not depress respiratory rate or hemoglobin oxygen saturation. Although the exact role of continuously administered opioids in managing acute postoperative pain has yet to be clearly defined, it is concluded that if properly used, this new transdermal device can be effective in providing a background of analgesia, which may assist in the management of acute postoperative pain as well as some chronic pain states.

Case ReportsBilateral continuous paravertebral block used for postoperative analgesia in an infant having bilateral thoracotomy.
We describe the successful postoperative pain management in an 11-month-old infant who underwent bilateral thoracotomy, using continuous infusions of bupivacaine into two directly placed paravertebral catheters. Haemodynamic parameters and pain scores were measured 1-2 h for 60 h while the infusions were continued and, intermittently, blood samples were taken for subsequent measurement of serum bupivacaine concentrations. ⋯ There were no adverse haemodynamic consequences or complications relating to either catheter placement or drug infusions. Serum concentrations of bupivacaine remained below toxic levels throughout the study period, though accumulation did occur.

Subcutaneous cannulae for morphine boluses in children: assessment of a technique.
Indwelling subcutaneous cannula for the administration of intermittent morphine boluses postoperatively have been used in several centers as an alternative to intramuscular (IM) injections. We introduced this technique to our hospital, assessed it for complications in 220 children, and conducted a survey to see if nursing staff preferred it to IM injections. The injections through the subcutaneous cannulae caused minimal distress to the children. There were no major complications, 95% of the nursing staff preferred this technique, and 74% would give morphine more readily to a child with a subcutaneous cannula in situ.

Clinical Trial Controlled Clinical TrialPerioperative analgesia for caesarean section: comparison of intrathecal morphine and fentanyl alone or in combination.
In a double-blind placebo-controlled trial we compared perioperative pain relief using different intrathecal opioid regimens given with bupivacaine during spinal anaesthesia for elective caesarean section. One hundred and sixteen patients undergoing elective caesarean section were divided into four groups (A, B, C, D) of 29 patients each. In addition to hyperbaric bupivacaine (12-14 mg), group A received 1 ml of normal saline, group B 25 microg of fentanyl, group C 100 microg of morphine, and group D received both fentanyl 25 microg and morphine 100 microg intrathecally. ⋯ The use of the opioids in association, however, was found to increase the incidence of side-effects. The quality of postoperative analgesia with fentanyl, when used alone, was found to be inferior to that with morphine. The combination of opioids offered no advantage over morphine alone.
