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。
Objective: To investigate the effect of periarthropic anesthesia on intraocular pressure (IOP) and ocular pulse amplitude (OPA). Methods: Thirty-two patients with monocular cataract were selected randomly. Periocular anesthesia was performed in the eyes and the other eyes were set as control. The IOP and OPA of the injected and control eyes were measured before and 3 and 10 minutes after anesthesia by dynamic contour tonometer , The data for statistical analysis. Results: There was no significant change in intraocular pressure between injected and control eyes after injection of lidocaine. The OPA of the injected eye was significantly reduced, while that of the control eye was elevated 3 minutes after injection and returned to pre-injection level 10 minutes later. CONCLUSIONS: Periarthral anesthesia can lead to a decrease in the amplitude of ocular motility without affecting IOP.
