目的探讨在小儿泪道冲洗中应用丁卡因进行表面麻醉的临床效果。方法将158例行泪道冲洗的患儿随机分为观察组81例和对照组77例。对照组予常规方法进行泪道冲洗;观察组在进行泪道冲洗前应用丁卡因进行表面麻醉。评价2组患儿的配合情况。结果观察组患儿配合良好者比例高于对照组,配合差者比例低于对照组,差异均有统计学意义(P<0.05)。结论对小儿泪道冲洗患儿实施丁卡因表面麻醉有利于减轻患儿的痛苦,缓解患儿紧张情绪,但在应用时应考虑到其过敏反应及对角膜上皮细胞的毒性作用,酌情应用。
Objective To investigate the clinical effect of tetracaine for surface anesthesia in pediatric lacrimal irrigation. Methods 158 cases of lacrimal duct wash were randomly divided into observation group of 81 cases and control group of 77 cases. In the control group, conventional lacrimal irrigation was performed. In the observation group, tetracaine was used for surface anesthesia before lacrimal irrigation. Evaluation of two groups of children with the situation. Results The proportion of well-matched children in the observation group was higher than that of the control group, and the difference between the two groups was lower than that of the control group (P <0.05). Conclusion The application of tetracaine topical anesthesia in children with lacrimal passage flushing is beneficial to relieve the pain of children and relieve the tension in children. However, the allergic reactions and the toxic effects on corneal epithelial cells should be considered in the application.
