Abstract:

Objective To investigate the current status of grip strength level in elderly patients with mechanical ventilation in ICU,and to explore its influencing factors. Methods The convenient sampling method was adopted to select 218 elderly mechanical ventilation patients in ICU of a tertiary hospital in Zhejiang Province as the research subjects from January 2020 to December,and researchers completed the cross-sectional study by using a general information questionnaire,an electronic grip strength device,and the Nutrition Risk Scaling 2002. Multivariate linear regression was used to analyse the factors influencing the grip strength level of elderly patients with mechanical ventilation. Results The average grip strength level of elderly patients with mechanical ventilation in ICU was（13.8±4.7） kg. Multivariate linear regression analysis showed that gender,age,exercise mode,time of sedative drugs,and score of Nutrition Risk Scaling 2002 were the main factors influencing their grip strength level（P<0.05）. Conclusion Grip strength levels were relatively low in elderly patients with mechanical ventilation in ICU. Grip strength levels were lower in patients with mechanical ventilation who were female,elderly,previously unexercised,the time of using sedation medication for >5 d,and the score of Nutrition Risk Scaling 2002≥3. Nursing staff should strengthen the dynamic evaluation of grip strength in patients with mechanical ventilation and control the related influencing factors.

摘要：

目的 调查ICU老年机械通气患者握力现状,并探讨其影响因素。 方法 便利选取2020年1月—12月浙江省某三级甲等医院ICU收治的218例老年机械通气患者作为调查对象,采用一般资料调查表、电子握力器、营养风险评估量表2002对其进行横断面调查。采用多元线性回归分析老年机械通气患者握力的影响因素。 结果 ICU老年机械通气患者的握力为（13.8±4.7） kg。多元线性回归分析显示,性别、年龄、运动方式、镇静药物使用时间、营养风险评估量表2002评分是影响其握力的主要因素（P<0.05）。 结论 ICU老年机械通气患者的握力较低,女性、高龄、既往不运动、镇静药物使用时间>5 d、营养风险评估量表2002评分≥3分的机械通气患者握力较低。护理人员应加强其握力的动态评估,控制相关影响因素。
