Abstract
Background : Postoperative haemoglobin oxygen saturation (SPO 2 ) may decrease after even minor surgical procedures. Aim : To evaluate the incidence of post-operative hypoxaemia in children randomized to receive either halothane-nitrous oxide (N 2 0) or propofol- nitrous oxide, during a standardized anaesthetic technique for superficial surgery. Method : All patients had standard anaesthesia with either of the two drugs. Oxygen saturation was monitored with a pulse oximeter. After tracheal extubation, all the patients received 100% oxygen for at least 3 minutes and then were transferred to the recovery room (RR) in the left lateral position. The SPO 2 values were monitored in the Recovery Room and supplemental oxygen was administered to all patients with SPO 2 less than 90%. Results : There were no significant differences in demographic characteristics or in the times to tracheal extubation and transfer to the RR between the two groups. While SPO 2 values decreased in both groups during transfer to the RR, they did not differ significantly at any time in the RR. Conclusion : The use of propofol does not decrease the incidence of postoperative hypoxaemia in the patient population studied. Journal of College of Medicine Vol. 11(1) 2006: 26-29
