支撑喉镜术中迷走神经反射的相关因素分析

Analysis of relative risk factors of vagal reflex in suspension laryngoscope surgery

目的探讨支撑喉镜手术中发生迷走神经反射的相关危险因素。方法对2010-06—2013-06在我院行支撑喉镜手术688例,对68例发生迷走神经反射患者回顾性分析。比较发生迷走神经反射患者与未发生患者的年龄、性别、基础疾病、情绪状况、声门暴露情况、血容量、麻醉情况,进而分析迷走神经反射的危险因素。结果患者是否发生迷走神经反射与年龄、性别及基础疾病无关(P>0.05),但情绪紧张、血容量过低、声门暴露困难、麻醉过浅会显著增加患者发生迷走神经反射的几率(P<0.05)。结论迷走神经反射严重影响撑喉镜手术的进行,了解其相关危险因素能够有效预防其发生,提高手术成功率。

Objective To investigate the relative risk factors of vagal reflex in suspension laryngoscope surgery.Methods The data of 688 patients performed suspension laryngoscope surgery were retrospective analysis from June 2010 to June 2013 in our hospital.These patients were divided into the occurred vagal reflex groups（n=68）and the non-occurred vagal reflex groups（n=620）.The age,gender,underlying diseases,emotional status,glottis exposure,blood volume and anesthesia of two groups were compared,and then the risk factors of vagal reflex were analyzed.Results Whether patients with vagal reflex had nothing to do with age,sex and underlying diseases（P〉0.05）,but the emotional stress,hypo-volemia,difficult glottis exposure and shallow anesthesia of patients could significantly increase the probability of patients with vagal reflex（P〈0.05）.Conclusion The relative risk factors of vagal reflex in suspension laryngoscope surgery are effectively eliminated to improve the success rate of surgery
