AbstractThis study was undertaken to evaluate the efficacy of subhypnotic doses of propofol for the prevention of nausea and vomiting in parturients undergoing caesarean section under spinal anaesthesia. In a randomized, double-blinded, placebo-controlled manner, 60 patients received intravenously lignocaine 0.1 mg/kg (for injection pain relief) followed by either placebo (Intralipid) or propofol at subhypnotic dose (1.0 mg/kg/h) (n = 30 of each) immediately after clamping of the fetal umbilical cord. Emetic episodes and safety assessments were performed during spinal anesthesia for caesarean section. The incidence of patients who were emesis-free in the intraoperative, post-delivery period was 37% with placebo and 77% with propofol, respectively (P = 0.001). No clinically important adverse events were observed in either group. In conclusion, a subhypnotic dose (1.0 mg/kg/h) of propofol is effective for preventing nausea and vomiting in parturients undergoing caesarean section under spinal anaesthesia.
