表面麻醉不做上直肌缝线小梁切除术

目的 探讨表面麻醉和不做上直肌固定缝线的方法在小梁切除术中的应用价值。方法 术前10min内用4g/L倍诺喜点眼表麻3次,消毒铺巾后将20g/L利多卡因棉片放置在上方球结膜表面,加强表面麻醉效果同时用以擦血,不做上直肌固定。结果 116例表面麻醉青光眼患者中达到Ⅰ级麻醉效果的88例(75.9％),Ⅱ级麻醉效果的23例(19.8％),Ⅲ级麻醉效果的5例(4.3％)。未置上直肌固定缝线的86例,均顺利完成手术。结论 表面麻醉下不做上直肌固定缝线进行小梁切除术,安全适用、方法可靠。

Trabeculectomy under topical anesthesia without superior rectus muscle suturing

Aim To evaluate trabeculectomy under topical anesthesia and without superior rectus muscle suturing. Methods Within 10 minutes before trabeculectomy, topical anesthesia was induced with Benoxil eyedrops, 4g/L, 3 times. In operation, cotton slice containing Lidocain, 20g/L was placed on the superior part of the ball conjunctiva to enhance topical anesthesia and to clean blood. Superior rectus was not sutured in the operation. Results Among the 116 glaucoma patients under this anesthesia, anesthesia outcome reached level I in 88(75.9%), level II in 23(19.8%) and level HI in 5(4.3%). Eighty-six cases who did not have rectus muscle sutured all had successful surgical outcome. Conclusion Trabeculectomy under topical anesthesia and without superior rectus muscle suturing is safe and reliable.
