  • 简介:护理安全是指在实施护理的全过程中,患者不发生法律和法定的规章制度允许范围内以外的心理、机体结构或功能上的损害、障碍、缺陷或死亡。通过对护理安全问题的分析,认为造成护理安全问题和护患纠纷的主要原因有护理人员方面的、管理方面及病人、社会方面的。只有依法行医、恪尽职守、加强自律和道德建设、规范服务行为、改善社会对医院的再认识,建立协调健康的医护关系,合理应用人力资源,优化护理管理制度,增强护理风险意识才能有效解决护理安全问题。

  • 简介:目的分析个性角膜切口对白内障术后角膜散光及裸眼视力的影响。方法90例(106眼)白内障患者分为2组,试验组选择位于角膜最大屈光度径线上透明角膜切口,对照组选择11:00处的透明角膜切口,行白内障超声乳化人工晶状体植入术。术前及术后1周、1个月、3个月分别检测患者角膜散光及视力情况。结果术后1个月和3个月试验组裸眼视力分别为(4.9±0.15)、(5.0±0.15),显著优于对照组的(4.8±0.18)、(4.8±0.20),差异有统计学意义(P〈0.05)。术后1个月和3个月试验组角膜散光度分别为(0.78±0.39)、(0.79±0.40),明显低于对照组的(1.53±0.32)、(1.52±0.28),差异有统计学意义(P〈0.05)。结论白内障患者术前大多存在〈1.5D的角膜散光。采用个性角膜切口可降低白内障手术角膜源性散光,术后视力恢复好,是一种简便、可行的手术切口。(中国眼耳鼻喉科杂志,2013,13:168—169,172)

  • 简介:目的探讨舒适护理在急性闭角型青光眼手术患者中的应用效果。方法将我科未开展舒适护理模式的2008年3月-2009年12月66例患者设为对照组,已开展舒适护理的2010年3月-2011年11月92例患者设为观察组。对照组给予常规护理和指导,观察组在常规护理的基础上,采用舒适护理方式并评价其效果。结果通过对青光眼患者的舒适护理干预,观察组焦虑状况低于对照组,病人舒适度高于对照组,两组差异有统计学意义(P〈0.05),观察组满意率明显优于对照组(P〈0.01)结论舒适护理可以增加患者的舒适程度,减轻负性情绪,对疾病的治疗、康复起积极作用。同时,有利于增进医患关系的和谐,提高护理满意率。
