A study was undertaken to evaluate the acute hemodynamic effects in ten patients from this clinic's long‐term peritoneal dialysis program. With a Swan‐Ganz catheter, the following parameters were measured in each patient during peritoneal dialysis: cardiac index, pulmonary artery pressure, right atrial pressure, inferior vena cava pressure, heart rate and arterial pressure. Mean predialysis cardiac index, stroke volume index and heart rate were normal. Predialysis pulmonary artery pressure and arterial pressure were slightly elevated. Mean weight loss during peritoneal dialysis was 1.6 kg. The most striking post‐dialysis changes were a significant 20% decrease of the cardiac index and a 17% decrease of the pulmonary artery pressure. Heart rate and arterial pressure remained constant due to a 25% increase of total peripheral resistance. After filling the abdomen with one, two and three liters of dialysate, intra‐abdomi‐nal pressure and inferior vena cava pressure increased up to 150 and loo%, respectively, whereas central hemodynamic parameters (pulmonary artery pressure, cardiac index, stroke volume index, heart rate and arterial pressure) were unchanged.
