简介:目的:评价新型硅胶管(RS一次性使用泪道引流管)治疗泪小管断裂的临床效果。方法:回顾性研究。收集2013-01/2015-10来我院就诊的47例47眼泪小管断裂患者完整的临床资料。在泪小管断裂吻合术中,新型硅胶管从上、下泪小点“U”形置入,在泪道中保留3mo。拔管后,观察泪道通畅率、是否伴有泪溢和其他并发症发生情况。结果:所有患者,泪小管吻合成功,新型硅胶管顺利植入。未发生硅胶管相关的并发症,如眼部刺激、泪小点外翻和撕裂、过早脱落等。治愈41例(87%),泪道冲洗通畅,无泪溢。部分治愈4例(9%),患眼轻微泪溢,但泪道冲洗通畅。失败2例(4%),患眼泪溢,泪道冲洗不畅。结论:在泪小管断裂吻合术中,新型硅胶管是一种安全、有效、无创的置入物,其操作过程简单,易于掌握,术者学习曲线短。
简介:目的探讨电话回访、微信等方式对闭角型青光眼患者出院后进行延伸护理服务,以提高患者遵医行为和改善护患关系的影响。方法将160例闭角型青光眼患者随机分为对照组和观察组各80例,对观察组患者于出院后第一周开始电话回访,以后分别于两周、一月、三月、六月、一年回访。对照组采用常规方法。一年后对2组患者遵医行为和再入院人数及满意度进行评价。结果观察组患者在随访期间遵医行为人数及满意度调查,明显好于对照组,再入院人数明显少于对照组(P〈0.01)。结论延伸护理服务有利于患者掌握闭角型青光眼相关的健康教育知识,增强患者遵医行为,调动患者的主观能动性,对延缓病情进展、预防并发症、减少再入院次数、减轻经济负担、提高生活质量起到了促进作用。
