碳酸利多卡因表面麻醉小切口白内障摘除折叠人工晶状体植入术的临床观察

目的探讨碳酸利多卡因注射液表面麻醉下行小切口白内障摘除联合折叠人工晶状体植入术的临床效果。方法 320例（320只眼）白内障患者分为碳酸利多卡因注射液表面麻醉组（A组）176例,倍诺喜滴眼液表面麻醉组（B组）144例,行上方巩膜隧道切口手法碎核白内障摘除联合折叠人工晶状体植入术,观察麻醉效果,视力恢复及手术并发症。结果 A、B组患者均能在表面麻醉下完成小切口白内障摘除折叠人工晶状体植入术,麻醉效果满意、视力恢复好,并发症少,且以上3项观察指标经卡方检验后两组间均无显著差异（P〉0.05）。结论在碳酸利多卡因注射液表面麻醉下能完成小切口白内障摘除联合折叠人工晶状体植入术,碳酸利多卡因注射液表面麻醉安全、有效。

Clinical observation of lidocaine carbonate topical anesthetic effect in small-incision cataract extraction with intraocular lens implantation

Objective To analyze the clinical effects of lidocaine carbonate anesthetic on the small-incision cataract extraction with intraocular lens implantation.Methods 320 cases(320 eyes) with cataract were treated by small-incision cataract extraction with intraocular lens implantation.Based on different topical anesthetic method,patients were randomly divided into lidocaine carbonate group(A group,176 cases) and Benoxil group(B group,144 cases),and the effect of topical anesthesia,postoperative visual acuity and complications were examed.Results Surgery was successfully performed in both A and B group under two different topical anesthetic Methods,and all of patients achieved satisfactory anesthetic effect,postoperative visual acuity and less complications.Among these indexs,there were no significant different between two groups(chi-square test,P>0.05).Conclusion Small-incision cataract extraction with intraocular lens implantation under topical anesthesia with lidocaine carbonate is safe and effective,which is suit for primary hospitals.
