球周麻醉对眼压及眼脉动振幅的影响

目的:探讨球周麻醉对眼压(IOP)及眼脉动振幅(OPA)的影响。方法:随机选择单眼白内障患者32例,患眼施行球周麻醉,另眼设为对照,分别于麻醉前及麻醉后3,10min采用动态轮廓眼压计测量注射眼和对照眼的IOP及OPA值,对数据进行统计学分析。结果:注射利多卡因后注射眼和对照眼的眼压均无明显变化。注射眼OPA值显著降低,而对照眼在注射后3minOPA值升高,10min后恢复至注射前水平。结论:球周麻醉可导致眼脉动振幅降低,而对眼压没有影响。

Effect of peribulbar anesthesia on intraocular pressure and ocular pulse amplitude

AIM: To investigate the effect of peribulbar anesthesia on intraocular pressure(IOP)and ocular amplitude pulse(OPA).METHODS: Thirty-two consecutive adult patients with monocular cataract enrolled in this study. IOP and OPA were measured with dynamic contour tonometer(DCT)before and 3, 10 minutes after administration of lidocaine anesthesia. Data were analyzed with software SPSS 11.5.RESULTS: The IOP remained stable in the injected eyes and the non-injected eyes after administration of lidocaine anesthesia. The OPA was significantly decreased after injection of anesthesia agent in the injected eyes. The OPA in the non-injected eyes increased significantly 3 minutes after injection of the anesthesia agent, returning to preinjection level 10 minutes after the injection.CONCLUSION: Peribulbar anesthesia leads to decrease of OPA and shows no effect on IOP in the injected eyes.
