ANESTHESIA FOR UROLOGICAL ENDOSCOPIC PROCEDURES IN ADULT OUTPATIENTS

The aim of this study was to establish whether propofol in combination with fentanyl or ketamine provides a good quality of anaesthesia and recovery time in urological endoscopic outpatient surgery. Sixty patie nts (ASA I-II) were assigned randomly to receive either 2.5 mu g kg(-1 ) fentanyl or 1 mg kg(-1) ketamine. In both groups anaesthesia was ind uced with propofol 1.5 mg kg(-1) and maintained with 7 mg kg(-1) h(-1) Patients breathed nitrous oxide and oxygen 3:2 spontaneously. Cardiov ascular parameters were more stable after ketamine. The most important side effect was the presence of apnoea lasting longer than 60 s in 14 patients receiving fentanyl. The time to establish alertness was shor ter in the ketamine group, who also had a better (P<0.05) as well as p ost-anaesthetic recovery room score.
