Abstract
Hemodynamic states in short-time dialysis were evaluated in 7 dialysis patients by means of a Swan-Ganz thermodilution catheter. Seven patients were treated with 3 hours hemodialysis (3hHD) with a large-surface-area dialyzer (n=4) or 4hrHD with a small-surface-area dialyzer (n=3), and with 3-h hemodiafiltration (HDF) or 4hHDF. Hemodynamic parameters, biochemical data, electrocardiography, chest X-ray films, echocardiography, and total body water by the use of deuterium oxide were compared for each dialysis treatment. There was no significant difference between 3hHD and 4hHD with regard to hemodynamic parameters, biochemical data, and so on. The same results were obtained for 3hHDF and 4hHDF. Hemodynamic stability thus depends not on dialysis treatment time but on volume removal. It is thus important to manage the degree of weight gain in order to control hemodynamic stability in short-time dialysis.
