Intradialytic measurement of cardiac output by thermodilution and impedance cardiography.
Impedance cardiography was compared with thermodilution cardiography in the measurement of cardiac output serially during maintenance hemodialyses in ten chronic uremic patients. Measurements were carried out pre-dialysis and post-dialysis as well as hourly during dialysis. The results demonstrated statistical identity between impedance and thermodilution cardiography at all times of measurement. The study confirms the validity of the non-invasive technique in measuring cardiac output in the uremic patient.
