摘要
目的研究导致ICU患者困难撤机的医源性因素。方法比较2007年3月～2010年3月间我院ICU收治的接受机械通气治疗的患者,分析困难撤机组与成功脱机组患者临床资料。结果困难撤机组患者气管切开率、较细口径导管使用率、呼吸机相关性肺炎发生率、意外拔管率、撤机不当率等明显高于成功脱机组,具有显著统计学意义(P<0.05)。结论人工气道建立方式、导管口径、院内感染、呼吸机管道的管理、撤机策略等是ICU患者困难撤机的医源性因素。
Objective To study the Iatrogenic factors of ICU patients with difficult weaning. Methods The data were analyzed on the reference of the patients from march 2007 to March 2010 who received mechanical ventilation in ICU, including the successfully weaning group and the difficult weaning group. Results The tracheotomy rate, the smaller caliber catheter usage rate, the ventilator-associated pneumonia incidence rate, the accidental extubation rate and the improper weaning rate in the difficult weaning group was higher than the successfully weaning group, with statistically significant （P〈0.05）. Conclusion The way of the artificial airway, catheter diameter, hospital-acquired infection, ventilator tubing management and the weaning strategies are the iatrogenic factors of difficult weaning .
