Randomized Controlled Trial Clinical Trial Controlled Clinical Trial
Analgesic combinations with orphenadrine in oral post-surgical pain.
Two hundred male and female patients underwent a variety of oral surgical procedures and were treated afterwards in four test groups. They took a combination of orphenadrine (25 mg) and acetaminophen (325 mg), either drug alone, or placebo. A double-blind study design was used. ⋯ Each active drug, in turn, was also significantly better throughout than placebo for pain relief. Sub-groups in each treatment regimen required additional pain relief prior to six hours, with significantly more placebo than orphenadrine-acetaminophen patients needing remedication. Side-effect incidence was very low and randomly distributed among the four groups.

Historical Article
Changes in obstetric anaesthesia in the last twenty-five years.
The last twenty-five years have provided a continuing success story in the achievement of satisfactory obstetric analgesia. Maternal mortality and morbidity from general anaesthesia has not decreased substantially. Mothers still run the same risk of inhalational pneumonitis and are even more likely to suffer the distressing experience of awareness. It must, however, be admitted that general anaesthesia for child-birth has brought increasing benefits to the new born during the last twenty-five years.

Anaesthesia is now an important cause of maternal death. Most deaths which occur in association with anaesthesia are preventable. ⋯ There remains the possibility of pulmonary irritation due to food particles, bile salts and even the antacid itself. The role of difficult or failed tracheal intubation is emphasized in the causation of hypoxia and the pulmonary aspiration of stomach contents.

Comparative Study Clinical Trial Controlled Clinical Trial
Pain relief in the post-operative period: a comparative trial of morphine and a new analgesic buprenorphine.
In a comparative trial, buprenorphine 0-3 mg or morphine 10 mg was administered intramuscularly to patients post-operatively. The new drug buprenorphine produced more pain relief than morphine and appeared to have a longer duration of action. The side-effects produced by the two drugs were similar, as were the effect on respiratory and cardiovascular measurements.

Comparative Study Clinical Trial Controlled Clinical Trial
Imipramine and rheumatoid factor.
It has been reported that imipramine reduces the titre of rheumatoid factor in schizophrenic patients. Twenty out-patients suffering from classical rheumatoid arthritis and having rheumatoid factor titre equal to, or greater than 1:64, were treated in a double-blind trial with imipramine 75 mg or matching placebo. In this study the dose of imipramine used failed to affect the levels of rheumatoid factor.
