Randomized Controlled Trial Comparative Study Clinical Trial
Controlled release morphine tablets: a double-blind trial in patients with advanced cancer.
Eighteen of 27 patients with pain due to advanced cancer, completed a randomised crossover comparison of 4-hourly aqueous morphine sulphate and twice daily controlled release morphine tablets. There was no difference between the two regimens in analgesic efficacy or adverse effects, but there was an apparent improvement in quality of sleep on the controlled release tablets. After completion of the study, 17 patients continued with the latter medication for periods that ranged from 2 days to 94 weeks (median 6.5 weeks). Controlled release morphine tablets given twice daily provide a simpler and more convenient treatment regimen than a 4-hourly opioid for patients with cancer pain, once they have been stabilised.

Randomized Controlled Trial Comparative Study Clinical TrialCaudal morphine for postoperative analgesia in children: a comparison with caudal bupivacaine and intravenous morphine.
We compared the efficacy, duration, and side effects of preservative-free morphine injected into the caudal space in children, with caudal bupivacaine and with intravenous morphine administration for relief of postoperative pain. Forty-six children, ages 1-16 yr, were randomly assigned to receive intravenous morphine (control group), caudal bupivacaine (0.25%, 1 ml/kg), or caudal morphine (0.5 mg/ml, 0.1 mg/kg). In half the patients given caudal morphine, the morphine was mixed with a dose of lidocaine adequate to produce sacral analgesia, to confirm correct caudal injection of the morphine. ⋯ The duration of analgesia was significantly greater with caudal morphine (median 12 hr, P less than 0.02) than with caudal bupivacaine (median 5 hr), and both were greater than with intravenous morphine in control patients (median 45 min). Urinary retention, pruritus, and nausea appeared with slightly greater frequency in the caudal morphine group, but no delayed respiratory depression occurred. Caudal morphine (0.5 mg/ml, 0.1 mg/kg) provided 8-24 hr of analgesia in children without a significantly greater incidence of side effects than caudal bupivacaine or intravenous morphine.

Randomized Controlled Trial Comparative Study Clinical Trial
The morphine sparing effect of ketorolac tromethamine. A study of a new, parenteral non-steroidal anti-inflammatory agent after abdominal surgery.
A randomised, double-blind study of patients after upper abdominal surgery was undertaken to assess the analgesic efficacy of ketorolac tromethamine, a new, parenteral non-steroidal anti-inflammatory agent. Postoperatively, patients received a 24-hour intramuscular infusion of either saline (n = 20), ketorolac 1.5 mg/hour (n = 21) or ketorolac 3.0 mg/hour (n = 20). Cumulative morphine requirements were measured using a patient-controlled analgesia system which delivered intravenous increments of morphine on demand. ⋯ This was associated with significantly lower pain scores. Patients who received the higher ketorolac dose had significantly less postoperative increase in arterial carbon dioxide tensions than controls. This study suggests that ketorolac tromethamine is a useful analgesic drug with significant morphine sparing properties.

Randomized Controlled Trial Clinical TrialTranscutaneous electrical nerve stimulation in acute hand infections.
Twenty-six patients with severe hand infections requiring operative drainage and admission to hospital were entered into a prospective, randomised, placebo-controlled trial. This was to test the use of a functioning transcutaneous electrical nerve stimulator and a non-functioning transcutaneous electrical nerve stimulator for pain relief in the first three postoperative days. ⋯ They also demonstrated highly significant improvement in their range of total active movement over those patients with a non-functioning transcutaneous electrical nerve stimulator. We recommend the use of transcutaneous electrical nerve stimulator after operation to reduce pain and improve mobility.

Randomized Controlled Trial Clinical Trial
Effect of i.v. lignocaine on pain and the endocrine metabolic responses after surgery.
Pain intensity, and blood glucose and plasma cortisol concentrations were measured following abdominal hysterectomy in 18 patients allocated randomly to receive either i.v. lignocaine 1.5 mg kg-1 plus 2 mg kg-1 h-1, or saline. The administration of lignocaine resulted in plasma concentrations between 1.5 and 2.0 micrograms ml-1 during the 2-h study period. However, the administration of lignocaine i.v. had no effect on the intensity of pain after surgery, or on the adrenocortical and hyperglycaemic responses to surgery.
