Abstract:
Objective To explore the antiemetic mechanism of propofol in patients subjected to laparoscopic cholecystectomy under general anesthesia Methods Sixty ASA Ⅰ Ⅱ patients of either sex undergoing elective laporoscopic cholecystectomy were randomly assigned to three groups : control group (group C), ondansetron group (group O) and propofol group(group P) Anesthesia was induced with thiopental 5 7 mg?kg -1 and intubation was facilitated with succinylcholine 1 1.5mg?kg -1 In group C and O anesthesia was maintained with inhalation of 1 0% 1 5% isoflurane and intermittent bolus of vecuronium In group O ondansetron 4 mg was given intravenously before induction of anesthesia In group P anesthesia was maintained with continuous intravenous infusion of 1% propofol at a rate of 50 150 ?g?kg -1 ?min -1 and intermittent bolus of vecuronium At the end of operation neostigmine 1mg and atropine 0 5 mg were regularly given to antagonize the residual neuromuscular blockade Venous blood samples were taken before anesthesia (baseline), after intubation, at the end of operation and 6h after operation for determination of plasma motilin(MTL) level Postoperative nausea and vomiting (PONV) was assessed according to WHO standard in four grades from no nausea to severe vomiting with gastric content Results In group C the plasma MTL level at the end of operation was significantly higher than that before anesthesia (P
