表面麻醉在大规模防盲手术中的应用

Topical anesthesia for large scale cataract surgery in visual rehabilitation

目的:评价盐酸奥布卡因(倍诺喜)在大规模小切口非超声乳化白内障防盲手术中的安全性及有效性。方法:对636例(636眼)基层贫困白内障患者在盐酸奥布卡因表面麻醉下行小切口非超声乳化白内障摘除联合人工晶状体植入术,观察其麻醉效果及术后视力。结果:所有患者在表面麻醉下均能很好的配合顺利完成手术,无1例中途更换麻醉方法。平均手术时间12.16min,术后第1d视力≥0.3者82.3%,术后3d≥0.3者93.9%。结论:盐酸奥布卡因表面麻醉下行小切口非超声乳化白内障摘除及人工晶状体植入术在基层大规模防盲中是安全快捷有效的。

AIM： To estimate the safety and validity of topical anesthesia with oxybuprocaine hydrochloride （ Benoxil） in large scale non-phacoemulsification cataract surgery through small incision. METHODS： Under topical anesthesia with oxybuprocaine hydrochloride, small incision non-phacoemulsification cataract extraction and IOL implantation were done in 636 needy patients （636 eyes） from basic level, and the effectiveness of topical anesthesia and postoperative visual acuity were surveyed. RESULTS： All operations were well done under topical anesthesia with oxybuprocaine hydrochloride, without any additional anesthesia. The mean duration of operation was 12.16 minutes. The vision ≥0.3 was 82.3% at the first day and 93.9% at the third day after surgery. CONCLUSION： Small incision non-phacoemulsification cataract extraction and IOL implantation under topical anesthesia with oxybuprocaine hydrochloride is a safe, rapid and effective method in large scale surgery of basic level.
