表面麻醉在小切口非超声乳化白内障摘除术中的应用

Topical anesthesia in small incision non-phacoemulsification cataract extraction

摘要: 目的:探讨表面麻醉在小切口非超声乳化白内障摘除术中应用的安全性、可靠性及有效性。方法:采用盐酸奥布卡因滴眼液进行表面麻醉,对45例53眼白内障患者施行小切口非超声乳化白内障摘除联合后房型人工晶体植入术,观察其麻醉效果及并发症。结果:49眼术中未感到疼痛或感到轻微疼痛,手术能顺利进行;3眼术中比较疼痛,经加滴1~2次表面麻醉药后仍能顺利完成手术;1眼行人工晶体后房悬吊固定时有痛感而加用筋膜囊下麻醉而完成手术。结论:表面麻醉在小切口非超声乳化白内障手术中确切有效,简单快捷,且并发症较球后麻醉少。但适应证的选择很重要,对手术并发症的处理有时要联合应用其他麻醉方式。

Abstract: Objective:To evaluate the security and efficacy of topical anesthesia in small incision non-phacoemulsification cataract extraction.Methods:Small incision non-phacoemulsification cataract extraction and intraocular lens (IOL) implantation were performed in 53 eyes of 45 patients under topical anesthesia with Benoxil;the anesthetic effects and surgical complications were observed.Results:The operation was carried out successfully in 52 eyes,with no additional anesthesia;only 1 eye was applied sub-tenon's capsule anesthesia for suture fixation of IOL.Conclusions:Topical anesthesia with Benoxil is a safe and reliable method for cataract surgery.
