Ventilator associated pneumonia (VAP) is a common complication in mechanically ventilated children and adults. There remains much controversy in the literature over the definition, treatment and prevention of VAP. The incidence of VAP is variable, depending on the definition used and can effect up to 12% of ventilated children. For the prevention and reduction of the incidence of VAP, ventilation care bundles are suggested, which include vigorous hand hygiene, head elevation and use of non-invasive ventilation strategies. Diagnosis is mainly based on the clinical presentation with a lung infection occurring after 48hours of mechanical ventilation requiring a change in ventilator settings (mainly increased oxygen requirement, a positive culture of a specimen taken preferentially using a sterile sampling technique either using a bronchoscope or a blind lavage of the airways). A new infiltrate on a chest X ray supports the diagnosis of VAP. For the treatment of VAP, initial broad-spectrum antibiotics should be used followed by a specific antibiotic therapy with a narrow target once the bacterium is confirmed.
呼吸机相关性肺炎(VAP)是机械通气儿童和成人常见的并发症。文献中关于VAP的定义、治疗和预防仍存在诸多争议。VAP的发病率因所采用的定义而异,可影响高达12%的机械通气儿童。为预防和降低VAP的发病率,建议采用通气护理集束措施,包括严格的手部卫生、抬高床头以及使用无创通气策略。诊断主要基于临床表现,即在机械通气48小时后发生肺部感染且需要改变呼吸机设置(主要是增加氧气需求,优先使用无菌采样技术采集的标本培养阳性,该技术可使用支气管镜或气道盲灌洗)。胸部X光片上新出现的浸润影支持VAP的诊断。对于VAP的治疗,应首先使用广谱抗生素,一旦确认细菌后,再使用针对性更强的窄谱抗生素治疗。
