ICU老年机械通气患者谵妄情况及其影响因素的调查

目的：了解ICU老年机械通气患者谵妄发生情况，并探讨其影响因素及采取相应的护理措施。方法采.用自行设计的调查问卷，对本科室210例机械通气老年患者进行调查，评估其发生谵妄情况，分析谵妄的影响因素。结果112例（53.3%）老年机械通气患者发生谵妄。机械通气时间、急性生理及慢性健康状况评分Ⅱ（acute physiology and chronic health evaluation，APACHEⅡ）、低氧血症、睡眠剥夺是影响老年机械通气患者谵妄发生的重要因素。结论老年机械通气患者谵妄发生率较高。提供亲情护理、密切观察病情变化、强化呼吸功能和现实定向认知能力训练对降低老年机械通气患者谵妄发生率具有重要意义。

Influencing factors of delirium of elderly patients with mechanical ventilation in ICU

Objectives To explore the influencing factors of delirium in elderly patients with mechanical ventilation in ICU. Methods Using a self-designed questionnaire,the investigation was done among 210 patients undergoing mechanical ventilation to evaluate the delirium condition and look into the influence factors of delirium.Results 112 cases（53.3%）of the elderly patients were affected with delirium.The major influencing factors included duration of mechanical ventilation,acute physiology and chronic health evaluation（APACHEⅡ）,hypoxia,sleep deprivation.Conclusion The incidence of delirium is higher among the elderly patients with mechanical ventilation.As for nursing strategy,providence of family nursing,close observation of the disease changes, enhanced respiratory function and practical orientation cognitive training are important for the reduction of the incidence of delirium in the elderly patients with mechanical ventilation.
