摘要
目的 了解表面麻醉剂对眼表面毒性损伤的情况。方法 分别用 30 g· L- 1 洁霉素、4g· L- 1 盐酸奥布卡因 (表麻滴瞳 )及 10 g· L- 1 盐酸丁卡因 ,对 3组滴眼 ,每 5 min1次 ,共 4次。并对滴药前后角膜地形图进行对比分析。结果 滴药后角膜地形图变化率 ,洁霉素组为 3.91% ,表麻滴瞳组为71.87% ,丁卡因组为 79.6 9% .结论 多次、不合理应用表麻制剂 ,可对眼表面造成毒性损伤 ,引起角膜上皮水肿。
Objective To find out the ocular surface toxic damage condition after using topical anesthetics.Methods 30g·L -1 Lincomycin,4g·L -1 Oxybuprocaine and 10g·L -1 Tetracaine were used to drop the eyes.The persons of the three groups were dropped using eye drops once/5 minutes,total four times.Then the corneal topography of pre using drops and post using drops were compared and analyzed. Results The corneal topography change rate after using drops: 30g·L -1 Lincomycin group was 3.91%,4g·L -1 Oxybuprocaine group was 71.87%,10g·L -1 Tetracaine group was 79.69%.Conclusion If we use the topical anesthetics more and more,or unreasonable,it can cause the toxic damage of ocular surface ,and increase the incidence rate of operative complication.
