Echocardiographic Hemodynamic Study during Ultrafiltration Sequential Dialysis

Abstract

Four patients on regular dialysis were studied by the echocardiographic method during ultrafiltration and dialysis performed sequentially according to 2 different protocols. Blood pressure, heart rate, cardiac output, stroke volume, systolic and diastolic dimension of the left ventricle, systolic and diastolic volumes of the left ventricle, ejection fraction, shortening fraction and total peripheral vascular resistance index were measured. During ultrafiltration there is an increase of the total peripheral vascular resistance index. Myocardial contractibility improved during dialysis. Physiopathologic implications are discussed.
