生物电阻抗测量作为一种简便、无创、低成本且重复性好的容量评估手段,其准确性及临床意义得到越来越多的证实,目前临床应用日益广泛。本文就生物电阻抗测量的基本原理、临床常用方法及不同人群(包括透析患者及危重症患者)中的应用及其局限性,探讨生物电阻抗测量在临床容量评估中的应用。 As a simple, non-invasive, low-cost and reproducible capacity assessment method, bioelectrical impedance measurement is more and more confirmed by its accuracy and clinical significance. At present, the clinical application is more and more widely. In this paper, the basic principle of bioelectrical impedance measurement, clinical common methods and different populations (including dialysis patients and critically ill patients) and its limitations in the application of bioelectrical impedance measurements in clinical capacity assessment.
