本文对ARDS患者VAP的发病率、危险因素及预后进行了研究。ARDS中VAP较为常见。通过侵袭性技术诊断VAP阳性率高。由于ARDS患者需要长时间机械通气,且常常接受广谱抗生素治疗,肺炎常由难治性病原体引起.医院内感染不影响这一高死亡率人群的存活率,但VAP却明显延长了机械通气时间。接受硫糖铝治疗的患者发生肺部感染的危险性明显增加。 发生ARDS时,肺炎的诊断难于确定。ARDS患者胸部X线片均存在弥漫性异常,所以很难觉察或断定有无X线变
In this paper, the incidence of VAP in ARDS patients, risk factors and prognosis were studied. VAP ARDS is more common. VAP-positive diagnosis by invasive techniques. Because ARDS patients require long periods of mechanical ventilation and are often treated with broad-spectrum antibiotics, pneumonia is often caused by refractory pathogens, which do not affect survival in this high-mortality population but VAP significantly prolongs duration of mechanical ventilation . Patients receiving sucralfate have a significantly increased risk of developing lung infections. ARDS occurs, the diagnosis of pneumonia is difficult to determine. ARDS patients with chest X-ray are diffuse abnormalities, it is difficult to detect or determine whether the X-ray variable
