Randomized Controlled Trial Clinical TrialA prospective study of patient-controlled analgesia. Impact on overall hospital course.
Previous studies have shown that patient-controlled analgesia (PCA) provides effective pain control in the postoperative patient. To determine the impact of PCA technology on the overall hospital course, we designed a randomized controlled study comparing patients receiving analgesia using PCA infusion (Abbott Lifecare, Abbott Laboratories; Chicago, IL) with patients receiving analgesia by traditional intramuscular or intravenous methods. All patients had undergone elective cholecystectomy. ⋯ Patients demonstrated a wide range of analgesic requirement in the first 24 hours but the average of the total analgesic required was higher in the PCA group (average, 29.5 mg) than the traditional group (22.8 mg). Urinary complications occurred more commonly in the group of patients receiving traditional analgesia than in the group of patients receiving analgesia with the PCA device. When compared with patients receiving analgesia by traditional methods, patients receiving the PCA infusion required more analgesia with fewer urinary complications and similar postoperative length of stay.

Randomized Controlled Trial Comparative Study Clinical TrialIntrapleural bupivacaine for early post-thoracotomy analgesia--comparison with bupivacaine intercostal block and cryofreezing.
54 patients who had posterolateral thoracotomy were prospectively studied to compare the efficacy of intrapleural bupivacaine with that of bupivacaine intercostal block and cryofreezing. Patients were randomized into three groups. The intrapleural catheter group included 16 patients who had intermittent intrapleural instillation of 20 ml of 0.25% bupivacaine for forty-eight hours postoperatively. ⋯ No complications related to the use of the intrapleural catheter or to bupivacaine toxicity were encountered. In conclusion, the technique of intermittent intrapleural bupivacaine is safe and comparable in efficacy to bupivacaine intercostal block and cryofreezing. Narcotic requirements may be reduced when this technique is used.

Randomized Controlled Trial Clinical Trial
Evaluation of ketorolac, ibuprofen, acetaminophen, and an acetaminophen-codeine combination in postoperative oral surgery pain.
Two-hundred six outpatients with postoperative pain after the surgical removal of impacted third molars were randomly assigned on a double-blind basis to receive oral doses of ketorolac tromethamine 10 and 20 mg, ibuprofen 400 mg, acetaminophen 600 mg, a combination of acetaminophen 600 mg plus codeine 60 mg, or placebo. Using a self-rating record, subjects rated their pain and its relief hourly for 6 hours after medicating. All active medications were significantly superior to placebo. ⋯ Repeat-dose data indicated that on the day of surgery ketorolac 10 and 20 mg and ibuprofen 400 mg were superior to acetaminophen 600 mg; ketorolac 20 mg was also superior to acetaminophen-codeine. Differences among active medications were not significant when data for the entire postoperative period (days 0-6) were evaluated. The frequency of adverse effects was similar for the active medications.

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.
