近年来,呼吸道感染已逐步取代泌尿系感染,成为医院最主要的医院获得性感染。ICU内危重病患者并发肺部感染的发生率高,临床救治困难,病死率可达50%以上。据报道,呼吸机相关性肺炎VAP发生率可达31.8%～46.0%,病死率高达20.0%～71.0%,随着床旁纤维支气管镜在临床应用的逐渐开展,目前已应用于支气管异物取出,局部注药治疗支气管扩张以及支气管良性狭窄等疾病中。本实验通过床旁支气管镜吸痰加灌洗联合常规抗感染治疗与常规抗炎综合治疗来观察其临床疗 In recent years, respiratory infections have gradually replaced urinary tract infections and become the most important hospital-acquired infections in hospitals. ICU critically ill patients complicated by high incidence of pulmonary infection, clinical treatment difficulties, the mortality rate of up to 50%. It is reported that the incidence of ventilator-associated pneumonia VAP rate of up to 31.8% ~ 46.0%, the mortality rate as high as 20.0% to 71.0%, with the bedside fiberoptic bronchoscopy in clinical applications has been gradually applied to the removal of bronchial foreign body, Local injection for the treatment of bronchiectasis and benign bronchial stenosis and other diseases. This experiment by bedside bronchoscopy suction sputum plus lavage combined with conventional anti-infective therapy and conventional anti-inflammatory comprehensive treatment to observe the clinical treatment
