Abstract

For anesthesia of sixty children undergoing elective tonsillectomy, we randomly assigned the patients as 2 groups, intravenous propofol for induction and 6-12 mg/kg/hr propofol infusion with 66% nitrous oxide for maintenance(propofol group) or intravenous 4 mg/kg thiopental for induction and inhalation of enflurane with 66% nitrous oxide for maintenance(enflurane group). We compared the effects of two groups for induction time, hemodynamic change, recovery time, and side effects. The results were as follows. 1) Time for loss of eyelid reflex was significantly shorter in enflurane group than in propofol group(P <0.05). 2) Heart rate was increased significantly in both groups at 1 min after intubation, 1 min after operation, 5min after end of operation(P< 0.05). But there were no significant differences between groups. 3) Systolic and diastolic arterial pressure were increased significantly in both groups at 1 min after intubation(P<0.05). But there were no siginificant differences between groups. 4) The recovery time was shorter siginificantly in propofol group than in enflurane group(P< 0.05), and recovery scores according to modified Steward coma scale were higher in propofol group than in enflurane group until 25 min after end of anesthesia(P< 0.05). 5) Pain on injection at induction was siginificantly more frequent in propofol group than in enflurane group(P< 0.05), and excitatory effect during emergence was significantly more frequent in enflurane group than in propofol group(P< 0.05).
