Resistivity and Blood Flow by Admittance Plethysmograph during Hemodialysis

概要

論文の詳細を見る
Resistivity and blood flow of the limbs were studied by Admittance Plethysmograph in two groups of dialyzed patients: Group A of CTR <50% and Group B of CTR ≥50%.Resistivity of Group A before dialysis was lower, and that after dialysis was higher, than that of normal subjects. This suggested that dialyzed patients were hypervolemia before dialysis and became hypovolemia after dialysis. Blood flow of these patients before dialysis was lower than normal subjects, which became much lower after dialysis.Resistivity of Group B was low both before and after dialysis, suggesting that the patients of high CTR values were always in the state of hypervolemia.From these results it seems reasonable to conclude that resistivity and blood flow can be indexes for adequate dialysis.
