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.

Randomized Controlled Trial Comparative Study Clinical TrialIntravenous regional anesthesia with 0.5% articaine, 0.5% lidocaine, or 0.5% prilocaine. A double-blind randomized clinical study.
The purpose of this study was to compare the effectiveness of three local anesthetic agents for intravenous regional anesthesia in the upper limb. Side effects and plasma concentrations of the drugs in the doses administered for IVRA were also studied. ⋯ Articaine had the fastest onset of sensory block and the lowest peak plasma concentration of the three local anesthetics when used for intravenous regional anesthesia.
