不同脱机组患者呼吸机撤离的影响因素分析

目的:分析不同脱机组患者脱机的可能影响因素。方法:对126例呼吸衰竭患者分为简单脱机组(59例)、困难脱机组(37例)和延长脱机组(30例),并分析其临床资料。结果:APACHE-Ⅱ评分、ICU住院时间、年龄及PaO2/FiO2在3组间差异有统计学意义(P<0.05);基础病以慢性阻塞性肺疾病(COPD)为主。结论:病情程度和氧合情况可以预测脱机的难易程度;对有脱机困难倾向者,应警惕甲状腺功能低下和神经肌肉疾病。

The analysis of related factors among different weaning groups on weaning from mechanical ventilation

Objective： To analyze the possible influence factors in different weaning groups. Method： 126 patients with respiratory failure were classified as simple weaning group（ n = 59）, difficult weaning group（ n = 37） and prolonged weaning group（ n = 30）, and their clinical data were analyzed. Result： 1. There were significant difference among the three groups on APACHE-II score , the length of ICU stay, and PaO2/FiO2 （P 〈 0.05） 2. Chronic obstructive pulmonary disease was still main reason of respiratory failure. Conclusion： The severity and the oxygenation condition of patients may predict the difficulty of weaning . Hypothyroidism and neuromuscular disease shouldn＇ t be ignored for the patients who have the tendency of difficult weaning .
