方法：选取2014-02/2015-06在我科住院后联合用药24～48h眼压控制不良的原发性青光眼患者46例46眼，于球筋膜麻醉下行复合式小梁切除术，观察麻醉效果及并发症。

结果：所有患者注射麻药后1min均能达到镇痛、眼球制动效果。手术过程中，0级麻醉效果35眼(76%)，1级麻醉效果10眼(22%)，2级麻醉效果1眼(2%)。除1例1眼患者术中需追加1次表麻剂后完成手术，其余患者均能在球筋膜麻醉下配合手术，麻醉总有效率为98%。术中术后无1例出现麻醉相关并发症。

结论：高眼压下复合式小梁切除术中应用球筋膜下麻醉安全有效、简便快捷。

METHODS:Forty-six eyes(46 cases)of primary glaucoma received compound trabeculectomy under Sub-tenon's anesthesia, whose preoperative intraocular pressure were higher than normal after 24 to 48h of combined medication. Both efficacy and complication of the anesthesia were studied.

RESULTS: One minute after anesthetic injection, all cases were able to achieve the effect of analgesia and eye brake. During the operation, 0 level of anesthesia effect included 35 eyes(76%), 1 level of anesthesia effect included 10 eyes(22%), 2 level of anesthesia effect included 1 eye(2%). Only 1 case of these patients needed to add the surface anesthetic once, and other cases were successfully operatedunder Sub-tenon's anesthesia. The total effective rate was 98%. No anesthesia complications occurred in all cases.

CONCLUSION:Sub-Tenon's anesthesia is safe, effective, simple and quick for compound trabeculectomy with high intraocular pressure.
