AbstractForty-four children, ASA physical status I or II, aged 1.5-14 years and admitted for strabismus surgery, were studied. The study compared the postoperative condition after two different anesthesia methods. All children were premedicated with midazolam rectally, received glycopyrrolate i.v. and were then randomised to one of two anesthetic methods: 1) induction with thiopental, maintenance with halothane or 2) induction with propofol supplemented with fentanyl, maintenance with propofol infusion. In both groups, tracheal intubation was performed after vecuronium i.v. and the children were ventilated manually. Peroperatively, patients receiving propofol/fentanyl had more episodes of bradycardia (P less than 0.001). Times to spontaneous breathing and extubation were shorter in the propofol/fentanyl group (P less than 0.05) and there was also a lesser degree of sedation during the first 2 h postoperatively (P less than 0.01). Fewer children in the propofol/fentanyl group vomited postoperatively (P less than 0.05). The apprehension score was higher in the propofol/fentanyl group compared to the thiopental/halothane group (P less than 0.05). We conclude that children undergoing strabismus surgery anesthetized with propofol/fentanyl had more episodes of peroperative bradycardia, a lower incidence of postoperative vomiting and a shorter recovery time, and were more apprehensive during the initial postoperative period than children anesthetized with thiopental/halothane.
