而柳叶刀2011年发表的META分析引用的文章为“Am J respir Crit Care Med 2005”。柳叶刀中的表述为
“VAP is defined as pneumonia in people who have a device to continuously assist or control respiration through a tracheostomy or by endotracheal intubation within 48h before the onset of infection, inclusive of the weaning period.”
从英文表述来看。这个定义分了两种情况
1.持续使用呼吸机引起的肺炎;
2.发生感染钱48小时内,通过气管造口术或者气管内插管的病例,而且还包括了断乳期【weaning period】
