简介:目的调查视网膜母细胞瘤(retinoblastoma,RB)患儿家长的心理健康状况。方法采用国际通用的焦虑自评量表和抑郁自评量表对121名患儿家长进行问卷调查,以国内常模作为对照。采用SAS8.0统计软件对数据进行t检验和方差分析。结果RB患儿家长的焦虑标准分(53.80±10.42)和抑郁标准分(58.90±10.89)均高于国内常模(P均〈0.0001)。双眼RB患儿家长的焦虑标准分(58.19±10.57)和抑郁标准分(62.46±11.84)明显高于单眼RB组(焦虑和抑郁值分别为51.73±9.77,57.22±10.09,P值分别为0.0083,0.0423)。患儿所处的治疗阶段不同,家长文化程度不同,家庭经济状况不同,家长的焦虑和抑郁程度也不同。结论RB患儿家长的焦虑、抑郁水平明显高于国内正常人群,提示对RB患儿家长进行心理疏导的必要性。
简介:目的:研究近视患者LASIK术后视疲劳的发生与融合范围的关系,及同视机融合功能训练改善LASIK术后视疲劳的疗效观察。方法:对60例120眼近视患者(.1.50--8.00D)施行LASIK手术,于术前戴全矫眼镜用同视机法测定融合范围,并进行视疲劳的问卷调查。术后将其随机平分为两组:A组进行同视机融合功能训练30d,B组不进行同视机融合功能训练,分别对其术后1wk;1mo行同视机法测定融合范围,并进行视疲劳的问卷调查及统计学分析。结果:A、B组术后融合范围均较术前减小。术后1wk时融合范围两组分别为18.58±8.91和13.45±8.87,二者差异有统计学意义(P〈0.05)。术后1mo时,两组融合范围分别为20.55±7.23和18.12±6.10,二者差异无统计学意义。术后1wk时A组视疲劳评分3.92±1.65,B组评分5.16±2.34,二者差异有统计学意义(P〈0.05)。术后1mo时两组评分分别是1.28±0.96和1.45±0.99分,二者差异无统计学意义。结论:近视眼LASIK术后双眼的融合功能下降是出现视疲劳的一个重要因素。术后早期进行同视机融合功能训练可以有效的改善视疲劳症状。
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。
