High Output Cardiac Failure

Factors affecting cardiac function in dialysis patients include arterial blood pressure, anemia, intra-vascular volume and the arteriovenous fistula (AVF). We investigated the acute and chronic effects of basilic vein transposition (mean upper arm brachial artery-basilic vein anastomosis) on both the cardiovascular system and the oxygen status.

Sixteen patients with end stage renal failure were enrolled in this study. Patients with heart failure, pericardial effusion or valvular heart disease were not included in the study. Echocardiography (preoperatively and six months after, stages 1 and 2 respectively) and a Swan-Ganz catheter (perioperatively) were used to assess the hemodynamic status during the phases of AVF construction. Flow measurements were made in the parts of the AVF system before, during and after the construction of the AVF.Moreover, at the same time phases blood sampling from the arterial line and the pulmonary artery catheter was performed, in order to assess oxygen and acidbase status.
