运动疗法应用于ICU困难撤机患者的效果评价

Effects of exercise therapy for patients with difficult weaning using mechanical ventilation

目的评价困难撤机患者在治疗期间采用运动疗法的干预效果。方法将63例困难撤机患者随机分为实验组33例和对照组30例。实验组在常规呼吸道护理基础上根据患者病情及体力进行循序渐进的4步运动疗法；对照组按常规进行呼吸道护理。比较2组不同时点的潮气量、呼吸频率、氧合指数等指标情况。结果机械通气第21天和第28天，实验组潮气量、呼吸频率、氧合指数（PaO2／FiO2）、急性生理与慢性健康评分（APACHEII评分）指标均显著优于对照组；机械通气第28天，实验组心率显著优于对照组；实验组患者机械通气日及ICU住院日均明显少于对照组；2组的并发症发生率比较差异无统计学意义。结论运动疗法对困难撤机患者具有积极的作用。

Objective To evaluate the effects of exercise therapy for patients with difficult weaning using mechanical ventilation. Methods A total of 63 patients with difficult weaning using mechanical ventilation were randomly divided into the experimental group（33 cases） and the control group（30 cases）. The patients in the control group received routine respiratory care, however, the patients in the experi- mental group received gradual and individualized exercise therapy according to patients condition and physical strength. The items such as the tidal volume,respiratory rate ,PaO2/FiO2 were compared between two groups. Results Compared with the control group,the tidal volume,respiratory rate,PaO2/FiO2 and the score of APACHE II were better in the experimental group on the 21th and 28th day after mechanical ventilation, the heart rate was better in the experimental group on the 28th day after mechanical ventilation. In addition,the duration of mechanical ventilation and ICU hospitalization was shorter in the experimental group. But the rate of complications showed no significant difference. Conclusions Exercise therapy has a positive effect on patients with difficult weaning using mechanical ventilation.
