目的探究危重患者胃管植入前用利多卡因进行鼻腔、咽喉部喷雾表面麻醉的效果,指导临床进行舒适无痛植入。方法选取最近我科室留置胃管的患者53例,依据入院日期随机将其分为两组,对照组使用常规方法的置入胃管,观察组给予2%利多卡因进行鼻腔、咽喉部喷雾表面麻醉后再置胃管,观察两组患者在置管过程中的恶心、呕吐、呛咳等不良事件发生率以及成功率等指标。结果观察组置胃管一次成功率高、不良事件发生率低,并且患者使用起来更舒适。结论小剂量利多卡因鼻腔、咽喉部喷雾表面麻醉后置胃管能减少不良事件的发生率并提高一次置入成功率,是一种简便、安全、有效的方法。
Objective To study the effect of nasal and throat sprayed surface anesthesia with lidocaine before gastric tube implantation in critically ill patients so as to guide the clinical implantation of comfortable and painless. Methods Fifty-three patients with gastric tube indwelling recently in our department were divided into two groups randomly according to the date of admission.
