目的 探讨腹部手术患者胃管留置的最佳方法及时机,为临床高效性护理提供借鉴.方法 临床收集210例行腹部手术的患者,随机分成3组,每组70例,其中A组在手术前30 min未麻醉时置入胃管,B组在麻醉后置入胃管,前两组均为徒手置入,而C组在麻醉后喉镜直视下置入胃管.之后比较3组患者的相关反应情况、一次性成功率及置管时间等.结果 A组患者置管时与置管后2 min的收缩压、舒展张压、心率及心脏耗氧率同置管前相比均具有统计学差异(P＜0.05)；在置管时及置管后2min的收缩压、舒张压、心率及心脏耗氧率方面,B组和C组分别同A组相比较,也均具有统计学差异(P＜0.05).在恶心及呕吐发生率、一次性成功率与置管所需时间方面,B组和C组分别与A组相比均具有统计学差异(P＜0.05),B组与C组相比也均具有统计学差异(P＜0.05).结论 胃管置入的最佳时机为全麻后,在喉镜直视下置入的效果最佳,不仅可以减轻了患者痛苦,还可提高护理的工作效率.%Objective To study the optimal time and method to indwell gastric tube for preoperative patients and to provide references to high efficient nursing care in clinics. Methods Totally 210 patients underwent abdominal operation were randomly divided into three groups (n = 70). The gastric tube was indwelled half an hour before operation in group A and after anesthesia in group B bare-handedly, while it was indwelled in group C after anesthesia under laryngoscope. The response of patients, intubatton achievement rate and gastric tube indwelling time among the three groups were observed and compared. Results In group A, the systolic pressures, diastolic pressures, heart rate and heart oxygen consumption rate at two minutes after indwelling were markedly different from those of during indwelling (P <0. 05). Such differences were also observed between group B and group A, group C and group A(P<0. 05). Statistical differences in incidences of nausea and vomiting as well as intubatton achievement rate were found between the three groups respectively ( P < 0. 05 ) . Conclusion The optimal time and method to indwell gastric tube was after anesthesia under laryngoscope. It can reduce the painfulness of the patients and promote the efficiency of nursing care.
