Comparative Study Clinical Trial Controlled Clinical Trial
Analgesia following oral surgery for day patients: a clincial comparison of two analgesics.
A single-blind, between-patient study was carried out in 167 patients following oral surgery to compare the effectiveness and tolerance of two combination analgesic preparations; pentazocine (15 mg) plus paracetamol (500 mg) and dextropropoxyphene hydrochloride (32.5 mg) plus paracetamol (325 mg). Assessments of pain and pain relief were made over two periods, initially over the 90 minute period following administration of either preparation and secondly, over the subsequent 3 days following discharge. At the hospital, those patients receiving pentazocine plus paracetamol achieved a greater relief of pain than those receiving dextropropoxyphene plus paracetamol, though the differences did not reach statistical significance. At home, pain relief was very similar for both groups of patients, both preparations being effective and well tolerated.

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.

Intercostal nerve blocks with 0-5 per cent bupivicaine were used for post operative pain relief in 100 patients having upper abdominal operations. The blocks were very effective in 86 patients and had an average duration of 11 hours. Two asymptomatic pneumothoraces occurred.
