肺部超声在呼吸机相关性肺炎中的应用进展

Application progress of lung ultrasound in ventilator-associated pneumonia

呼吸机相关性肺炎(VAP)是最常见的ICU获得性感染,患者死亡率高,常规诊断方法包括肺部X线检查和胸部CT检查,对危重患者行每日常规检查也相对困难。肺部超声是诊断社区获得性肺炎的可靠方法,但其在VAP中的诊断作用有待进一步探讨,本文就VAP的诊断现状,以及肺部超声在VAP中的应用、随访和动态监测进行综述。

Ventilator-associated pneumonia(VAP)is the most frequent intensive care unit-acquired infection that is independently associated with high mortality rate.Chest-X-ray and CT imaging are used for conventional assessment of VAP,but these examinations are unreliable in daily practice for critically ill patients.Lung ultrasound is a reliable tool to diagnose community-acquired pneumonia.However,its diagnostic value in VAP needs to be further explored.This paper reviews the current diagnosis,the application,follow-up and dynamic monitoring of lung ultrasound in VAP.
