For the direct laryngoscopy and microscopic examination of the larynx with exploratory excision and pulpectomy using low frequency jet-ventilation with 100% @entity26 we used total intravenous anaesthesia with a strong acting opioid and a barbiturate. Because the achievement of sufficient reflexes and a high degree of vigilance postoperatively are to be aimed, @entity3694 (M) and @entity4490 (T) were investigated in the regard of the suppression of vigilance in the postoperative period. 40 @entity1 were randomly assigned to the group M (n = 20) or T (n = 20). The evening before operation, an intelligence test and a syndrome-short-test (SST) were performed for the measurement of attention and memory (functional @entity716 ). The @entity1 received 2 mg Flunitrazepam orally and transdermal @entity5591 . On the day of operation the @entity1 received 1 mg Lormetazepam orally for premedication. Anaesthesia was induced with 2 mg @entity8651 , 1 mg @entity680 , 1.4 mg/kg bodyweight M respectively 5 mg/kg bodyweight T and 1.4 mg/kg bodyweight @entity2900 . Immediately before laryngoscopy the @entity1 received 2-4 mg @entity680 . Muscle relaxation was achieved by an infusion with @entity2900 using relaxometry. @entity3694 respectively @entity4490 were administered by infusion depending on clinical signs indicating insufficient anaesthesia. The following parameters were measured: Blood pressure, heart rate, duration of operation and anaesthesia, parameters of vigilance 30, 60 and 120 minutes after operation (SST) and the ability of performance. The groups were comparable with respect to all data except the parameters of vigilance. The @entity1 receiving M were significantly more vigilant 30 min., 60 min. (SST) and 120 min (SST) after the end of anaesthesia than @entity1 receiving T (p = 0.01).(ABSTRACT TRUNCATED AT 250 WORDS)
