不同麻醉下视网膜脱离手术中的眼心反射观察

Observation of oculocardiac reflex during retinal detachment surgery with different anesthesia

目的:观察不同麻醉方法下视网膜脱离外路手术中的眼心反射。方法:选取我科2008-06/2010-03住院患者109例109眼,随机分为对照组和治疗组,分别采用球后阻滞麻醉与静脉复合麻醉进行视网膜脱离外路手术,观察术中血压、心率、眼心反射、血氧饱和度等情况。结果:与球后阻滞麻醉比较,静脉复合麻醉下眼心反射发生率低,收缩压、舒张压及平均血氧饱和度变化较小,经统计学处理,差异有统计学意义(P<0.01)。结论:静脉复合麻醉下行视网膜脱离外路手术相对安全,并发症少,效果满意。

AIM： To observe the oculocardiac reflex during retinal detachment surgery with different anesthesia. METHODS：The retrobulbar block anesthesia and balanced anesthesia for scleral buckling of the retinal detachment were compared. 109 eyes were randomly divided into two groups, control group and treatment group, to observe the effects of surgery. Blood pressure, heart rate, oculocardiac reflex and degree of blood oxygen saturation were compared. RESULTS： The balanced anesthesia was better than the retrobulbar block anesthesia in scleral buckling . The oculocardiac reflex incidence rate was lower. Changes of systolic pressure,diastolic pressure, mean degree of blood oxygen saturation were less. The effectiveness of anesthesia was good. Comparing the two methods ,there was statistical significance（ P〈 0.01 ）. CONCLUSION： The balanced anesthesia for scleral buckling is more safe,with less complication, high patient satisfaction and cooperation.
