[Intramuscular premedication with diazepam in a fat emulsion].

10 mg of diazepam in fat emulsion was given for premedication intramuscularly to 106 patients. In 53% of the cases patients were well sedated, 33% were apprehensive, 14% anxious. Pain related to the injection was complained of by 4 patients. Plasma concentration of diazepam at induction (60 minutes after the injection) was 130 ng/ml. Compared to diazepam in propylene glycol, pain at the injection side was less frequent while the level of sedation and the plasma concentration of diazepam were similar.
