目的 评价表面麻醉联合前房麻醉行白内障超声乳化摘除及人了晶体植入术的效果。方法 各种白内障共37只眼,术前15分钟先使用1％丁卡因滴眼三次,每次1～2滴,间隔3～5分钟。手术开始后,先作侧切口,从侧切口滴入2％利多卡因,0.1ml于前房内。结果 分别以无痛感、轻微痛但能耐受手术及痛不能耐受手术来评价麻醉效果,术中无一例诉痛不能耐受者,四只术眼在用齿镊夹结膜固定眼球或分开球结膜及角巩缘切中时诉轻微疼痛。撕囊、超乳及人工晶体植入等前房内操作中一例诉眼部疼痛。结论 表面麻醉联合前房麻醉行白内障超声乳化摘除及人工晶体植入术是可行的,可避免球后麻醉或周麻醉带来的并发症。
Objective To evaluate the effect of surface anesthesia combined with anterior chamber anesthesia in cataract phacoemulsification and human lens implantation. Methods A total of 37 eyes of various cataracts, 15 minutes before the first use of 1% tetracaine drops three times, each 1 to 2 drops, an interval of 3 to 5 minutes. After surgery, the first side of the incision, drip from the side incision 2% lidocaine, 0.1ml in the anterior chamber. The results were painless, mild pain, but can tolerate surgery and pain can not tolerate surgery to evaluate the effect of anesthesia, no case of pain can not tolerate patients, four eyes with tweezers to fix the eye conjunctiva or ball Conjunctival and angle margins cut when complained of slight pain. One case of ocular pain in anterior chamber operation such as capsulorhexis, phacoemulsification and intraocular lens implantation. Conclusion The combination of topical anesthesia with epicardial anesthesia in cataract phacoemulsification and intraocular lens implantation is feasible and can avoid the complications caused by retrobular anesthesia or perioperative anesthesia.
