Randomized Controlled Trial Clinical TrialDoes epidural sufentanil provide effective analgesia per- and postoperatively for abdominal aortic surgery?
To assess the efficacy of epidural sufentanil in providing per- and postoperative analgesia, 40 patients undergoing elective abdominal aortic surgery received either 50 mu g sufentanil in 10 ml normal saline solution (n = 20, ES group) or 10 ml normal saline (n = 20, control group) via a thoracic epidural catheter. The study solution was given (double-blind and at random) after the patients had been anaesthetized with i.v. midazolam, sufentanil and vecuronium. Anaesthesia was maintained with 60% nitrous oxide in oxygen and halothane at a 1% inspiratory concentration. ⋯ The mean dose administered i.v. did not differ significantly between the two groups: 105 +/- 109.5 mu g vs 138.5 +/- 126.9 mu g (mean +/- SD) in 5 and 13 patients, respectively. No cardiovascular changes were observed after the epidural bolus dose. Postoperative analgesia, consisting of a continuous epidural infusion of 50 mu g sufentanil in 50 ml bupivacaine 0.125% at a rate of 6-10 ml/h after a bolus dose of 10 ml of this solution, was adequate in the majority of patients, as determined by VAS-scores assessed during the epidural treatment (4.3 +/- 1.5 days).

Randomized Controlled Trial Multicenter Study Clinical TrialOral tramadol and buprenorphine in tumour pain. An Italian multicentre trial.
In this multicentre trial tramadol and buprenorphine were compared for the treatment of neoplastic pain no longer responsive to non-steroidal antiinflammatory drugs. A total of 131 adults (86 M, 45F) were treated with tramadol (one 100-mg slow-release tablet every 8-12 h), or buprenorphine (one sublingual 0.2-mg tablet every 6-8 h). The trial was to continue for up to six months. ⋯ There were six drop-outs in the first group (9%) and seven in the second (11%). Serious symptoms arose more frequently in the buprenorphine group (19% cf. 10%). No signs of dependence or tolerance were noted.

Randomized Controlled Trial Comparative Study Clinical TrialSublingual buprenorphine compared to morphine delivered by a patient-controlled analgesia system as postoperative analgesia after prostatectomy.
After open prostatectomy, 52 patients were randomly allocated to two treatment groups. Group A (26 patients) received buprenorphine sublingually, and in group B (26 patients) the analgesia was induced using a patient-controlled analgesia system with morphine. ⋯ There were no significant differences in visual pain scores, side effects, mean arterial blood pressure, pulse rate and respiration rate between the two groups. Sublingual application of buprenorphine offers an effective and easy alternative to the parenteral route of morphine for the management of postoperative pain.

Randomized Controlled Trial Comparative Study Clinical Trial[Combination of intravenous patient-controlled analgesia with epidural anesthesia for postoperative pain therapy].
The aim of this study was to prove the hypothesis that a combination of epidural anaesthesia with intravenous patient-controlled analgesia (PCA) could improve perioperative pain management. Patients of the urological department undergoing lower abdominal surgery were randomized for two different pain managements. Patients of group 1 (n = 37) were narcotized, intubated and ventilated for the operation; arriving at the recovery room, they were given a PCA-pump, the drug used was piritramide and the parameters were bolus 2.5 mg, blocking time 20 minutes and no basal infusion rate. ⋯ The benefits of better pain management contrast with the risks resulting from combining the two techniques. In our patients we found an improvement of pain management in the early postoperative period. The combination of epidural anaesthesia with intravenous patient-controlled analgesia can be regarded as a further possibility for treating postoperative pain in the sense of "balanced pain management".

Randomized Controlled Trial Comparative Study Clinical TrialA double-blind comparison of morphine infusion and patient controlled analgesia in children.
The analgesia provided after major abdominal surgery in 30 children by continuous morphine infusion and patient controlled analgesia, also using morphine, was compared using a double-blind, double-dummy design. The groups of children were comparable in age, weight, duration of operation and sex ratio. ⋯ Children aged between nine and 15 years achieved better pain relief with patient controlled analgesia. No difference could be shown in children aged between five and eight years.
