[Comparative study of the oral administration of flunitrazepam with oral pentobarbital and intramuscular administration of atropine and pethidine (meperidine) as premedication].
Thirty-four patients were allocated at random to treatment with 1 mg of flunitrazepam, orally, the night before operation, and 1 mg on the morning of operation (Group 1), and another 34 to treatment with 100 mg of pentobarbital, orally, the night before operation, followed by intramuscular atropine (0.01 mg/kg)+pethidine (meperidine 1 mg/kg) on the morning of operation (Group 2). The patients in both groups slept equally well. As far as apprehension and excitement (= anxiolytic effect) just before induction of anaesthesia were concerned, oral flunitrazepam proved to be markedly better than i.m. atropine+pethidine. There were no significant differences in cardiovascular variables between the two groups. From the anaesthesiologist's point of view, atropine had beneficial antisecretory effects, but, from the patients point of view, it caused only a subjective unwanted effect (dry mouth). In our opinion, oral flunitrazepam is a useful alternative agent for routine premedication. However, when used without i.m. atropine, excessive salivary secretion in some patients may occur and be disturbing, especially during extubation.
