Randomized Controlled Trial Comparative Study Clinical Trial
Analgesic efficacy and side-effect profile of paracetamol/codeine and paracetamol/dextropropoxyphene after surgical removal of a lower wisdom tooth.
A double-blind randomized analgesic trial was carried out on 180 patients undergoing surgical removal of an impacted lower wisdom tooth. The patients took their first dose of either 1000 mg paracetamol plus 60 mg codeine or 650 mg paracetamol plus 65 mg dextropropoxyphene when pain appeared after the decline of the local anaesthesia. If needed, another two doses were available during the observation period (less than or equal to 10 h). ⋯ Sufficient pain relief was obtained in most patients. The pain reduction after the first dose was 64% in the group receiving paracetamol/codeine compared with 53% in the group receiving paracetamol/dextropropoxyphene and the mean durations of effect of the first dose were 6.6 and 5.8 h, respectively. Side-effects appeared in all patient groups but were most frequent in women taking paracetamol/codeine.

Randomized Controlled Trial Comparative Study Clinical Trial
Double-blind comparison of the efficacy of extradural diamorphine, extradural phenoperidine and i.m. diamorphine following caesarean section.
A randomized, double-blind study of the efficacy, duration of action and side effects of three analgesic regimens following Caesarean section is described. Patients received i.m. diamorphine 5 mg, extradural phenoperidine 2 mg or extradural diamorphine 5 mg. Analgesia was of rapid onset in all groups, as judged by reductions in linear analogue pain scores and rank pain scores. ⋯ Itching was reported on direct questioning by 50% of patients in the extradural groups. No serious side effects were reported. Factors affecting the disposition of extradurally administered diamorphine are discussed.

Randomized Controlled Trial Clinical TrialContinuous-plus-on-demand epidural infusion of buprenorphine versus morphine in postoperative treatment of pain. Postoperative epidural infusion of buprenorphine.
In a randomized, double-blind study, buprenorphine was compared with morphine in the treatment of pain after major abdominal operations by means of continuous-plus-on-demand epidural infusion for constant analgesia. The patients received bolus epidural injections of 0.15 mg buprenorphine or 2 mg morphine-HCl prior to an on-demand epidural infusion of 0.03% buprenorphine or 0.25% morphine HCl at a basal rate of 0.06 ml/h. ⋯ Under the treatment, no discomfort or side-effects necessitating treatment occurred. We conclude that buprenorphine is a useful substitute for morphine in the treatment of pain after major abdominal operations by continuous-plus-on-demand epidural infusion, and that the relative analgesic potency ratio of epidural buprenorphine is 8.

Clinical Trial Controlled Clinical Trial
Analgesic efficacy of paracetamol/codeine and paracetamol/dextropropoxyphene in pain after episiotomy and ruptures in connection with childbirth.
Pain after episiotomy and/or perineal/vaginal rupture in childbirth is severe in many patients and in most cases it can be treated with oral analgesics. In this trial the efficacy and side-effect profile of two combination analgesics, paracetamol/codeine and paracetamol/dextropropoxyphene hydrochloride, were compared in post-partum pain after episiotomy and/or rupture of the perineum. Eighty-five patients were analysed for efficacy and 96 were included in an analysis of side-effects. Paracetamol/codeine was shown to give faster and more efficient pain relief while not causing constipation or other troublesome side-effects.

Randomized Controlled Trial Clinical Trial
Intraoperative bupivacaine during outpatient hernia repair in children: a randomized double blind trial.
Postoperative pain is a major problem following surgery in the ambulatory child. A study was undertaken to test the effect of intraoperative bupivacaine on postoperative pain in children undergoing outpatient hernia repair. Ninety-nine children aged 1 to 7 years underwent outpatient inguinal herniorrhaphy under general anesthesia. ⋯ Activity level at home on the day of surgery did not differ significantly between groups, but activity level over the following 48 hours was higher in group 1 (P less than .05). The two groups were similar with respect to all other parameters. We conclude that intraoperative bupivacaine decreases post-operative pain and analgesic use, and promotes early ambulation in children undergoing hernia repair.
