Randomized Controlled Trial Comparative Study Clinical Trial
Dose requirements, efficacy and side effects of morphine and pethidine delivered by patient-controlled analgesia after gynaecological surgery.
We have compared the dose requirements and side effects of morphine with those of pethidine when administered by patient-controlled analgesia in 40 patients (ASA I-II, 20-65 yr) after elective total abdominal hysterectomy. Patients were allocated randomly, in a double-blind manner, to receive either morphine (bolus dose 2 mg, lockout time 10 min) or pethidine (bolus dose 20 mg, lockout time 10 min) for postoperative pain relief. ⋯ Four patients receiving pethidine were withdrawn because of postoperative confusion and one receiving morphine because of intractable nausea and vomiting. The 95% confidence interval for this difference between the groups for VAS scores of sedation, nausea and pain were approximately 30 mm.

Randomized Controlled Trial Clinical TrialAdditive analgesic effect of codeine and paracetamol can be detected in strong, but not moderate, pain after Caesarean section. Baseline pain-intensity is a determinant of assay-sensitivity in a postoperative analgesic trial.
A randomized, double-blind, placebo-controlled single oral dose study was done in order to examine whether codeine has an additive analgesic effect to that of paracetamol for moderate and strong postoperative pain after abdominal surgery. The maximum recommended single dose of paracetamol 1000 mg (Paracet) was compared with a combination of a submaximal dose of paracetamol 800 mg plus codeine 60 mg (Paralgin forte) and placebo for pain relief after Caesarean section in 125 patients. ⋯ This study thus confirms that codeine has additive analgesic effect to paracetamol in pain after surgery. Our results show the importance of initial pain intensity in postoperative assessment of analgesic drugs. Assay-sensitivity and test power are increased by selecting patients with sufficiently high initial pain intensity and by comparing groups of patients with identical surgery and similar demographic variables.

Randomized Controlled Trial Comparative Study Clinical Trial
Randomized, single-blinded trial of laparoscopic versus open appendectomy in children: effects on postoperative analgesia.
The benefit of laparoscopy to patients has been clearly established in adults undergoing cholecystectomy. Results are less clear for appendectomy. The current study was undertaken to compare the respective 3-day postoperative periods after laparoscopic and open appendectomy in children. ⋯ Laparoscopy did not improve analgesia and postoperative recovery after appendectomy in children.

Randomized Controlled Trial Comparative Study Clinical TrialA comparison of the efficacy of ketorolac and indomethacin for postoperative analgesia following laparoscopic surgery in day patients.
The analgesia provided in the postoperative period by three regimens commonly used in our private anaesthetic practice were compared in a double-blind study of one hundred and thirty-seven women presenting for day-case laparoscopic procedures. After random allocation into three groups, all patients were similarly anaesthetized and then received both a rectal suppository and an IM injection. Group P received two placebos, Group I had an indomethacin suppository 100 mg and Group K an IM injection of ketorolac 30 mg. ⋯ The parenterally administered ketorolac may be a useful analgesic supplement in these patients. However the trial was aborted following the appearance in the literature of case reports of postoperative renal failure. Further investigation of the efficacy and side-effect profile of reduced doses may be warranted.
