简介：目的探讨运用示教与反示教在年龄相关性白内障患者滴眼药护理中的效果。方法将100例患者随机分为实验组和对照组各50例，对照组采用传统的健康教育。实验组采用示教与反示教进行健康教育。由培训过的责任护士对患者有计划地从入院到出院，给予全程、个体化的示教与反示教健康教育。结果实验组患者在滴眼药知识、技能掌握及对护理工作满意度方面优于对照组，差异有统计学意义（P0．05），术后一周并发症的发生率明显低于对照组（P〈O．05）。结论运用示教与反示教对患者实施健康教育，可达到提高患者滴眼药的技能，自我效能感增加，遵医行为增强，自护能力提高，减少术后并发症，提高护理满意度。

简介：目的：分析23G玻璃体切割术后高眼压的发生率、特点及相关的危险因素,为处理及预防提供依据。方法：对于我院行23G玻璃体切割手术的患者146眼临床资料进行回顾分析,术后早期高眼压诊断标准为术后2wk内任一时间眼压测量值≥25mmHg。采用卡方检验进行统计学分析;对于术后早期高眼压患者根据眼压程度采用单一或联合降眼压药物治疗。结果：患者146眼中发生术后高眼压者42眼,占28.8%,平均出现自术后3.38d。单纯气换组、C3F8填充组及硅油填充组术后高眼压发生率分别为14.5%,33.3%和39.3%,C3F8组和硅油填充组与单纯气换组比较均有统计学意义;未行激光机冷冻处理组、部分视网膜光凝组、全视网膜光凝组及冷冻组术后早期高眼压的发生率分别为13.6%,27.4%,34.5%和35.7%,部分视网膜光凝组与未处理组相比较没有统计学意义,而其他两组与未处理组比较有统计学意义;不同原发病术后均有早期高眼压的发生,但分布不均衡。通过处理眼压均控制理想。结论：23G玻璃体切割术后早期高眼压的危险因素是多方面的,主要与眼内填充物、术中处理方式有关,不同原发病对于高眼压的影响在于其对术式的影响。术后早期高眼压多为一过性,合理药物治疗可控制。
