摘　　要：目的研究球周麻醉后上睑下垂的发生情况并与球后麻醉进行比较。方法采用2点注射法球周麻醉，观察58例白内障摘除手术病人术后1天、1周、1月、3月、5月时上睑下垂的发生率，并分成二年龄组进行统计分析。结果球周麻醉后上睑下垂发生率较球后麻醉组发生率高，且时间延长；年龄大于或等于50岁组较年龄小于50岁组球周麻醉后上睑下垂发生率在早期无差异，但前者上睑下垂消失慢。结论球周麻醉较球后麻醉易于出现上睑下垂，其原因可能和麻醉药品的肌毒性作用有关。The purpose of this study was to determine if the incidence of ptosis is greater with retrobulbar or periocular anesthesia. Methods periocular anesthesia was conducted in 58 patients undergoing cataract surgery and retrobulbar anesthesia was performed in 70cases. Ptosis was defined as a drop in the lid margin of 2mm or greater. The position of the lid margin was documented preoperatively and postoperatively at 1、 7、30、 90、 150 days. Results The ptosis was more common in the periocular anesthesia group. In the periocular anesthesia patients, ptosis persisted longer in the patiauts who aged more than 50 years old. Conclusion Pericular anesthesia can increase the risk of post -anesthetic ptosis. it may be related to the myotoxicity of local anesthetic drug.
