Randomized Controlled Trial Comparative Study Clinical TrialNefopam and ketamine comparably enhance postoperative analgesia.
Opioids alone sometimes provide insufficient postoperative analgesia. Coadministration of drugs may reduce opioid use and improve opioid efficacy. We therefore tested the hypothesis that the administration of ketamine or nefopam to postoperative patients with pain only partly alleviated by morphine reduces the amount of subsequent opioid necessary to produce adequate analgesia. ⋯ Supplemental morphine (i.e., after test drug administration) requirements were significantly more in the control group (mean +/- sd; 17 +/- 10 mg) than in the nefopam (10 +/- 5 mg; P <0.005) or ketamine (9 +/- 5 mg; P <0.001) groups. Morphine titration was successful in all ketamine and nefopam patients but failed in four control patients (two because of respiratory toxicity and two because of persistent pain). Tachycardia and profuse sweating were more frequent in patients given nefopam, and sedation was more intense with ketamine; however, the incidence of other potential complications did not differ among groups.

Randomized Controlled Trial Comparative Study Clinical Trial
A placebo-controlled randomized clinical trial of perioperative administration of gabapentin, rofecoxib and their combination for spontaneous and movement-evoked pain after abdominal hysterectomy.
Current treatments for post-injury movement-evoked pain are inadequate. Non-opioids may complement opioids, which preferentially reduce spontaneous pain, but most have incomplete efficacy as single agents. This trial evaluates efficacy of a gabapentin-rofecoxib combination following hysterectomy. ⋯ These data suggest that a gabapentin-rofecoxib combination is superior to either single agent for postoperative pain. Other benefits include opioid sparing, reduced interference with movement, mood and sleep and increased PEF suggesting accelerated pulmonary recovery. Future research should identify optimal dose-ratios for this and other analgesic combinations.

Randomized Controlled Trial Comparative Study Clinical Trial
Double epidural catheter with ropivacaine versus intravenous morphine: a comparison for postoperative analgesia after scoliosis correction surgery.
Major spine surgery with a dorsal or ventrodorsal approach causes severe postoperative pain. The use of continuous epidural analgesia through one or two epidural catheters placed intraoperatively by the surgeon has been shown to provide efficient postoperative pain control. In this prospective unblinded study, the authors compared the efficacy of continuous intravenous morphine with a continuous double epidural catheter technique with ropivacaine after scoliosis correction. ⋯ Both methods provide efficient postoperative analgesia. However, double epidural catheter technique provides better postoperative analgesia, earlier recovery of bowel function, fewer side effects, and a higher patient satisfaction.

Randomized Controlled Trial Clinical TrialDose minimization study of single-dose epidural morphine in patients undergoing hip surgery under regional anesthesia with bupivacaine.
In order to decrease the rate of adverse effects, we aimed to identify the lowest analgesic dose of epidural morphine administered to patients undergoing hip surgery. ⋯ In patients undergoing hip surgery under regional anesthesia with bupivacaine, epidural morphine at a dose of 11.2 microg.kg(-1) administered immediately after completion of the procedure resulted in adequate pain relief for more than 12 h. Explanation of the high rate of patients vomiting (>45%) remains to be elucidated.

Randomized Controlled Trial Clinical TrialThe effect of intra-articular methadone on postoperative pain following anterior cruciate ligament reconstruction.
Intra-articular narcotics have proven efficacy for providing pain relief following knee arthroscopy. This effect is short-lived. Methadone, with its long serum half-life (thirty-five hours, compared with two hours for morphine) could provide improved and prolonged pain relief. The purpose of the present study was to examine the effects of an intra-articular injection of methadone on postoperative analgesia following arthroscopic anterior cruciate ligament reconstruction. ⋯ The present report represents the first known study of the use of intra-articular methadone and establishes that this analgesic is safe at a single dose of 5 mg. At this dose, however, methadone does not provide improved postoperative analgesia following arthroscopic anterior cruciate ligament reconstruction. In contrast, intra-articular morphine does appear to be effective for decreasing postoperative pain.
