The authors evaluated the effi ciency and reproducibility of cardiac output measurement by esophageal continuous-wave Doppler ultra sonography (ECO). A total of 114 si multaneous measurements of ECO and thermodilution cardiac output (TDCO) were compared in 25 surgi cal patients undergoing general anes thesia in the supine position. ECO could be obtained easily with mini mal experience by means of a com mercially available Doppler cardiac output monitor. There was a signifi cant correlation between ECO and TDCO (
