Abstract
35 patients with chronic renal failure were examined during the first 2 h of hemodialysis
by invasive and non-invasive methods. The cardiac output was determined by the dye
dilution technique in 11 of these patients and by Swan-Ganz catheterization in 5.
In the patients without severe myocardial damage, the cardiac output during hemodialysis
showed a significant increase (p < 0.05), accompanied by a significant decrease of
both mean blood pressure (p < 0.05) and total peripheral resistance (p < 0.05). Mean
pulmonary artery pressure and pulmonary artery wedge pressure were reduced in all
cases during hemodialysis. The increase in cardiac output during hemodialysis in patients
with chronic renal failure may be attributed to the decrease in afterload.
