【摘要】 目的评估昏迷患者角膜病变的发生状况并分析其危险因素,为临床专科护理实践策略的发展提供依据。方法采用研究对象情况调查问卷并借助荧光染色和便携式裂隙灯对重症监护室的102例昏迷患者进行测评和分析。结果昏迷患者角膜上皮脱落的发生率达12.7%。眼睑闭合不全、镇静剂的使用、瞳孔检查的间隔时间是发生角膜病变的危险因素(均P<0.05)。结论昏迷患者有较高的角膜病变发生率,尤其是眼睑闭合不全和使用镇静剂的患者,以预防为主的眼部护理应成为重症护理的必要组成部分。更多还原

【Abstract】 Objective To explore the incidence and the risk factors of corneal defects in coma patients,and to provide information for clinical nursing practice.Methods One hundred and two coma patients staying in the intensive care units of a hospital were recruited in this study.They were investigated with a questionnaire in terms of demographic and disease-associated variables.They were also examined for corneal epithelial erosion by fluorescent staining and a portable slit lamp.Results Corneal epithelial erosion was presented in 12.7% of the patients.Lagophthalmos patients,sedated patients and frequently examined patients were at high risk of developing corneal defects(P<0.05 for all).Conclusion The coma patients are more susceptible to corneal defects,which are especially common in the lagophthalmos and sedated patients.Preventive eye care should be considered as an important component of critical nursing.更多还原
