[The effect of various drugs on post-operative pain-producing sensations]

The influence of diazepam, the hemisuccinic ester of oxazepam, fentanyl and pentazocine on pain-producing sensation after surgery was tested in 160 patients subjected to ordinary and major surgery. Use was made of Dundee and Moore's modification of Clutton-Brock's test, and Bromage's test. Analysis of the results indicated that the slow administration of analgesics and psychoactive drugs enables better results to be achieved, with smaller amounts of active substance.
