摘　　要：肺灌注电阻抗断层成像(electrical impedance tomography,EIT)作为一种床旁无创、连续、动态、无辐射的肺通气监测技术,目前已广泛应用于急危重症患者的诊疗。除肺通气监测外,近年来高渗盐水造影肺灌注EIT床旁监测也备受关注。本文介绍高渗盐水造影肺灌注EIT技术床旁评估2例肺动脉内膜剥脱术后患者的肺灌注情况,为该技术在此类患者围术期管理中的应用提供参考。Pulmonary electrical impedance tomography(EIT),a noninvasive,continuous,dynamic,and radiation⁃free bedside imaging technique for monitoring pulmonary ventilation,is now widely utilized in the diag⁃nosis and management of critically ill patients.Beyond ventilation monitoring,hypertonic saline contrast⁃enhanced EIT for bedside pulmonary perfusion assessment has recently garnered significant attention.This article describes the application of hypertonic saline contrast⁃enhanced EIT to evaluate pulmonary perfusion in two patients follow⁃ing pulmonary endarterectomy,providing a reference for its perioperative application in such patients.
