ICU机械通气患者脱机失败原因分析

目的:分析机械通气患者脱机失败原因,提高脱机成功率。方法:对2001年1月至2004年9月间,我院ICU收住的42例机械通气患者脱机失败69例次,进行回顾性调查分析。结果:69例次脱机失败中,生理学指标变化41例次(59.4%),原发病恶化17例次(24.6%),通气策略不当11例次(15.9%)。结论:机械通气失败的原因依次为生理学指标变化、原发病恶化和通气策略不当。因此,机械通气患者脱机时应掌握适宜的脱机时间和脱机的模式。

Investigation on the Reasons of Unsuccessful Weaning in Patients Receiving Mechanical Ventilation in Intensive Care Unit

Objective: To analyze the reasons unsuccessful weaning in patients receiving mechanical ventilation in intensive care unit(ICU), in order to promote the rate of successful weaning. Method: The information of 69 unsuccessful weaning cases in 42 patients receiving mechanical ventilation in ICU were investigated. Result: The reasons of unsuccessful weaning were as follows,the changes of physiological index accounted for 59.4%(41 cases), deterioration of generated disease 24.6%(17 cases) and improper strategy of weaning 15.9%(11 cases). Conclusion: The reasons of unsuccessful weaning were changes of physiological index ,deterioration of generated disease and improper strategy of weaning ,so we should hold the proper weaning time and mode in weaning.
