目的 观察置入胃管一次性吸引复合托烷司琼预防全身麻醉术后恶心呕吐(PONV)的效果.方法 80例择期气管插管全身麻醉下行腹腔镜下胆囊切除术的恶心呕吐高危患者,ASAⅠ或Ⅱ级,患者随机分为置入胃管组(S组)和托烷司琼组(T组),每组各40例.采用常规麻醉诱导和维持.S组气管插管后在可视喉镜下经鼻置入胃管,连接吸引器吸引胃内容物,吸引完毕后立即拔出胃管.手术结束前30min,S组和T组均静脉给予托烷司琼2mg.观察并记录术后24h内恶心呕吐发生情况.结果 与T组相比,S组术后24h PONV的发生率明显降低(P<0.01),其程度明显减轻.结论 全身麻醉气管插管后置入胃管对胃内容物一次性吸引措施复合托烷司琼可减少恶心呕吐高危患者术后恶心呕吐的发生并降低其严重程度.%Objective o investigate the effect of gastric tube placement disposable suction combined with tropisetron against postoperative nausea and vomiting(PONV)in patients at high risk of nausea and vomiting after general anesthesia. Methods Eighty ASAⅠor Ⅱ patients at high risk of nausea and vomiting underwent laparoscopic cholecystectomy were randomly divided into placing stomach tube group(group S)and tropisetron group(group T),forty cases in each group. Anesthesia was the conventional induction and maintenance of general anesthesia. In group S,patients were placed gastric tube around 55 cm with video laryngoscope after tracheal intubation. The gastric contents were attracted by connecting the attractor. And the gastric tube was pulled out immediately. Tropisetron 2 mg were given to patients in group S and 30 min before the end of surgery in group T. The incidence of nausea and vomiting was recorded for 24 h. Results 24 h after surgery,the incidence of patients who suffered PONV was significantly lower in Group S compared with Group T . Conclusion The gastric tube placement disposable suction combined with tropisetron decrease the incidence and intensity of PONV in patients at high risk of nausea and vomiting after general anesthesia.
