导丝加利多卡因在人工气道昏迷患者胃管置入中运用

Application of guide wire plus lidocaine in artificial airway coma patients with gastric intubation

目的探讨建立人工气道后昏迷患者胃管置入方法,以提高插胃管成功率,减少患者不良反应。方法将100例建立人工气道后需要置入胃管的昏迷患者,随机分为观察组和对照组各50例,对照组按传统插胃管方法进行,观察组采用导丝加利多卡因进行插管操作。结果观察组一次成功率明显高于对照组,置管过程中烦躁呛咳、恶心呕吐等不良反应明显低于对照组。结论导丝加利多卡因能提高人工气道昏迷患者置胃管成功率,置管前后血压、心率、血氧饱和度变化不大,具有可操作性。

Objective To explore the method for gastric intubation in coma patients with artificial airway in order to improve the success rate of gastric intubation and reduce the adverse re- actions of patients. Methods A total of 100 coma patients who needed the gastric intubation after the construction of artificial airway were randomly divided into control group （n -50） and observa- tion group （n = 50）. The control group received the conventional method of gastric intubation while the observation group received guide wire plus lidocaine for gastric intubation. Results The success rate of first intubation in the observation group was significantly higher than that in the control group, and the adverse reactions such as dysphoria, bucking, nausea and vomiting were significantly lower than in the control group. Conclusion The guide wire plus lidocaine method can improve the success rate of gastric intubation in coma patients with artificial airway, and it is available for opera- tion because of its little change of blood pressure, heart rate and saturation of blood oxygen before and after catheterization.
