不同时间留置胃管对腹部术前病人影响的研究

Study on influence of different times of gastric tube indwelling for preoperative patients before abdominal region surgery

[目的]了解腹部术前病人置入胃管的最佳时机。[方法]将195例腹部择期手术病人随机分为两组,A组于术前半小时置入胃管,B组于麻醉后置入胃管。观察两组病人术前心理状况、咽喉部刺激症状及对心血管系统的影响。[结果]A组术前心理不适的发生率(6 7.0%)高于B组(15.8%)。A组置管后5 min咽喉部刺激症状发生率为100.0%,而B组无一例发生咽喉部刺激症状。A组置管时、置管后1 min、置管后5 min收缩压、舒张压、心率和心脏耗氧率均高于置管前,并且也高于B组。[结论]腹部手术病人留置胃管的最佳时机应是麻醉后。

Objective; To find out the optimal time for preoperalive patients to indwell gastric tube. Method： A total of 195 cases of time- selective operation in abdominal region surgery were divided into group A and group B randomly. Patients of group A were accepted gastric tube indwelling half an hour before operation. Patients of group were indwelled after anesthesia. Then indexes including preoperative psychological status, laryngopharyngeal irritations, and the influence on cardio- vascular system were observed. Results： The incidence of psychological indisposition among prcoperative group A cases accounted for 67.0 %, which was markedly higher than that of group B patients （15.8%）. All cases （100.0%） of group A developed laryngopharyngeal irritations 5 minutes after gastric tube indwelling. No one developed those symptoms among group 13 patients. The systolic and diastolic pressures, heart rate, and heart oxygen consumption rate of group A patients during tube indwelling and 1 min, 5 min after indwelling were all higher than before tube indwelling. Which were also higher than the corresponding times of group B cases. Conclusion： The optimal time of gastric tube indwelling for abdominal region operation patients is after their anesthesia.
