表面麻醉在抗青光眼小梁切除术中的有效性及安全性

目的：评估采用表面麻醉在抗青光眼小梁切除术中的有效性及安全性。方法：对30例青光眼患经表面麻醉进行小梁切除术与相同例数的表眼患同期采用球后麻醉进行小梁切除术两组患的麻醉效果作对比。结果：表面麻醉组中：30例（100％）均能较好配合手术，术中无一例需追加球周或球后麻醉，球后麻醉组中，球出血，眼睑皮下出血，球膜水肿及睑裂狭窄等发生率明显高于表面麻醉组（P＜0．01），1例发生球后出血，1例发生一过性黑蒙。结：面麻醉是青光眼小梁切除术一种安全有效的麻醉方法，临床上值得应用与推广。

Study of Effectiveness and Safety on Surface Anesthesia in Anti-glaucoma Trabeculectomy

Objective: To evaluate the effectiveness and safety of surface anesthesia to anti-glaucoma tra-beculectomy. Methods: The anesthesia effects on anti-glaucoma operations were compared between 30 cases with surface anesthesia and 30 cases with retrobulbar anesthesia. Results: In surface anesthesia group, the anesthesia was satisfactory in all cases without additional use of retrobulbar or peribulbar anesthesia and no complication occurred. In retrobulbar anesthesia group, there were higher rates of complications, such as retrobulbar hemorrhage, subcutaneous hemorrhage of eyelid, globular conjunctival edema and blepharostenosis. compared to surface anesthesia group ( P <0. 01 ). Conclusion: To anti-glaucoma trabeculectomy, the suface anesthesia was effective, safe and deserved to be used widely in clinical practice.
