Randomized Controlled Trial Comparative Study Clinical TrialComparison of intramuscular analgesia, intercostal block, epidural morphine and on-demand-i.v.-fentanyl in the control of pain after upper abdominal surgery.
Eighty patients undergoing upper abdominal surgery were randomly allocated to four groups according to the postoperative pain treatment. All patients had a standardized balanced anaesthesia and for postoperative analgesia either intramuscular oxycodone and/or metamizol (IM), intercostal block with 0.5% bupivacaine (IC), epidurally 4 mg morphine (EM) or i.v. infusion of fentanyl 0.54-0.99 micrograms min-1 + on-demand boluses of 7.2-13.5 micrograms (ODAC) were given. The pain intensity 2 h postoperatively was similar in all groups, mean score ranging from 3.2-4.3 on a scale from 0-10. ⋯ The amount of fentanyl infused in 24 h to the ODAC patients varied considerably, 814-2233 micrograms, as did the number of on-demand boluses, 3-155. At 24 h, an efficacy rating "good" was distributed as follows: IM 9/20, IC 11/20, EM 11/20 and ODAC 13/20. In the whole patient material 92.5% rated their condition as "good" or "fair".

Randomized Controlled Trial Clinical Trial
Extradural morphine and pain relief following episiotomy.
One hundred and fifty obstetric patients, who had received intrapartum extradural analgesia with bupivacaine, and had required episiotomy, were given a final postpartum injection of preservative-free morphine in saline, or saline alone, on a double-blind basis. The degree of perineal analgesia was assessed by linear analogue scale at intervals up to 36 h, and oral analgesic requirements were recorded. A significant degree of analgesia was obtained for up to 12 h with morphine 2 mg, compared with saline. Increasing the dose to 4 mg increased the occurrence of side-effects, and was associated with less marked analgesia.

Randomized Controlled Trial Clinical TrialEvaluation of the transcutaneous electrical nerve stimulator for postoperative analgesia following cardiac surgery.
The effectiveness of transcutaneous electrical nerve stimulation (TENS) in postoperative pain relief was assessed in this prospective randomised controlled study of 31 patients during the first 72 hours after cardiac surgery. Fourteen patients were given functioning TENS units, and seventeen patients were given non-functioning units. Postoperative pulmonary function tests, analgesic requirements and the incidence of atelectasis were compared in the two groups. ⋯ The forced vital capacity (FVC) was significantly larger with functioning TENS units on the second postoperative day, but there were no other significant differences in forced expiratory volume in one second (FEV1) or forced vital capacity (FVC) values between the two groups. A questionnaire given to patients assessing their opinions of the effectiveness of the TENS unit for analgesia showed a placebo effect in some patients with non-functioning units. In summary, this study suggests that TENS may be of benefit in postoperative pain relief after cardiac surgery, especially on the second postoperative day.

Randomized Controlled Trial Comparative Study Clinical TrialA comparison of morphine and buprenorphine for analgesia after abdominal surgery.
Eighty fit adults having elective abdominal hysterectomy or cholecystectomy received buprenorphine or morphine intravenously at the start of peritoneal closure, in a randomised double-blind trial. The anaesthetic sequence precluded the use of other narcotic analgesics. Pain scores were lower in patients who received buprenorphine, as were the cumulative numbers of patients withdrawn from the trial at each interval because of pain, statistical significance being achieved at all intervals from one to seven hours after administration. ⋯ One patient with protracted drowsiness and slow respiratory rate after buprenorphine received naloxone. No serious side-effects were noted. Buprenorphine 4-6 micrograms/kg provided adequate postoperative analgesia of greater duration than could be achieved with morphine, and the potency of buprenorphine when administered in this way was at least 33 times that of morphine.

Randomized Controlled Trial Comparative Study Clinical Trial
[Analgesia and adverse effects of nalbuphine (Nubain) in comparison with morphine following hysterectomy].
In a randomized double-blind-study nalbuphine 20 mg i.m. was compared with morphine 10 mg i.m. in 49 patients over the first 48 postoperative hours after hysterectomy. Nalbuphine proved to be a good analgetic, not statistically different from morphine but having statistically significantly fewer side effects.
