Randomized Controlled Trial Comparative Study Clinical Trial
Double-blind evaluation of buprenorphine hydrochloride for post-operative pain.
In a double-blind, random assignment study of four groups of 40 patients, relief of severe pain with buprenorphine hydrochloride 0.2 mg or 0.4 mg was evaluated and compared with morphine sulphate 5 or 10 mg. Evaluations included pain intensity, pain relief, sedation and other effects for up to 12 hours after drug administration, following recovery of wakefulness from anaesthesia for major abdominal surgery. Analyses of five parameters showed that the four groups were statistically comparable and that buprenorphine hydrochloride is at least 50 times more potent than morphine sulphate and has a substantially longer duration of analgesic action. Further clinical evaluation is, therefore, recommended.

Anidoxime: a clinical trial of an oral analgesic agent.
The new oral analgesic drug anidoxime was compared with dihydrocodeine. There were no side-effects, and no significant differences between the effects of dihydrocodeine 50 mg, anidoxime 75 mg or anidoxime 100 mg.

Randomized Controlled Trial Comparative Study Clinical TrialA model to evaluate mild analgesics in oral surgery outpatients.
A model was developed to evaluate mild analgesics in an oral surgery outpatient clinic population. On a report form, patients recorded starting pain and then pain intensities, relief responses, and side effects hourly for 3 hr after drug administration. The treatments were randomly allocated to patients on a single-dose-only basis, and the double-blind technique was used. ⋯ Both aspirin 650 mg and acetaminophen 600 mg proved superior to placebo (p less than 0.01) for all measures of effect with both parametric or nonparametric analyses, while codeine 30 mg was not significantly superior to placebo in any analysis. Codeine 60 mg proved significantly superior to placebo for certain measures of effect when analyzed with the nonparametric model. There was no significant interaction between either aspirin or acetaminophen and codeine.

Randomized Controlled Trial Comparative Study Clinical TrialEffect of paracetamol, mephenoxalone and their combination on pain following bone surgery.
Sixty patients suffering moderate postoperative pain after bone surgery were divided randomly into 3 treatment groups on the day following operation. Under double blind conditions they received either 400 mg mephenoxalone, a weak sedative, or 900 mg paracetamol, or the same doses of these drugs simultaneously, three times daily for three days. ⋯ However, during repeated administration over 3 days, the mean effect of the drug combination was slightly better than that of paracetamol or mephenoxalone alone. The drug combination did not induce more sedation or gastrointestinal side effects than either drug alone.

Randomized Controlled Trial Comparative Study Clinical Trial
Effect of intercostal nerve blockade during operation on lung function and the relief of pain following thoracotomy.
The use, during operation, of intercostal nerve blocks with lignocaine and bupivacaine for the relief of pain following thoracotomy was assessed in 138 patients. Irrespective of the method used to evaluate efficacy, it was not possible to demonstrate a lasting effect of clinical significance favouring either local anaesthetic agent. This form of treatment, although free from serious side effects, had no beneficial effects on lung function and is not recommended for the relief of pain following surgery.
