斜视矫正手术中心电图的观察

The Electrocardiographic Observation of Orthopia Operation

目的:探讨斜视矫正手术中心电图的改变相关因素、特点、防治措施。方法:观察200例斜视手术患者的手术过程中心电图变化,归纳防治措施。结果:儿童患者、全麻患者较容易发生眼心反射,内直肌、下斜肌眼心反射发生率较高,超过90%,均显著高于其他眼外肌(P<0.05)。术中发生心电图改变以窦性心动过缓为主,远高于其他心电图改变人数(P<0.05)。术前应用阿托品患者眼心反射发生率(37.8%)低于未应用阿托品者(76.2%),发生率有统计学差异(χ2=5.44,P<0.05)。结论:年龄、麻醉方式影响斜视手术中眼心反射的发生,眼心反射发生时心电图改变有一定规律,术前应用阿托品有可能降低眼心反射的发生率。

Objective：To investigate the related factors,characteristics,prevention measures of orthopia operation on operation ECG changes.Method：Observation the ECG operation changes of 200 orthopia operation patients,summarized prevention measures.Results：The children and general anesthesia patients were more prone to oculocardiac reflex,the oculocardiac reflex of medical rectus and inferior obliquus at a higher rate,over 90%,were significantly higher than other oculorotatory muscle（P0.05）.The bigest ECG changes of operation were sinus bradycardia,far higher than other ECG change number（P0.05）.The incidence of the oculocardiac reflex（37.8%）of preoperative application atropine patients was lower than no application atropine patients（76.2%）,the incidence had statistical difference（χ 2 = 5.44,P0.05）.Conclusion：age,anesthesia mode influent the oculocardiac reflex of orthopia operation,the ECG change had certain rules when oculocardiac reflex occurs,application atropine preoperative may reduce the incidence of oculocardiac reflex.
