我院重症监护室在2014年开始对慢性阻塞性肺疾病(COPD)采用机械通气治疗的患者开展监测胃残余量工作的研究,通过控制胃残余量减少患者食道反流、吸入性肺炎的发生,并因此有效减少了呼吸机相关性肺炎的发生率,缩短了患者机械通气治疗的时间。1资料与方法1.1临床资料入选我院2014年在重症监护室机械通气时间超过48h、进行肠内营养的COPD患者89例。男53例,女 Our hospital intensive care unit began work on monitoring residual gastric volume in patients undergoing mechanical ventilation in patients with chronic obstructive pulmonary disease (COPD) in 2014. By controlling gastric residual volume to reduce esophageal reflux, aspiration pneumonia, And thus effectively reduce the incidence of ventilator-associated pneumonia and shorten the time of mechanical ventilation in patients. 1 Materials and Methods 1.1 Clinical data Selected in our hospital in 2014 in the intensive care unit mechanical ventilation more than 48h, 89 patients with enteral nutrition COPD. 53 males and females
