HEMODYNAMICS IN CHRONIC RENAL FAILURE UNDER HEMODIALYSIS

Hemodynamics in 14 cases on initial hemodialysis (H.D.) and 16 cases on long-term H.D. were studied before, during and after H.D. with use of Swan-Ganz catheter. The results obtained were as follows:
1. The hemodynamics in chronic renal failure were classified into four types by pulmonary wedge pressure (PWP) of which the standard value (SV) was 10 mmHg and cardiac index (C.I.) of which SV was 4.5 L/min/M². 1) Type H was the hyperdynamic type where the PWP was lower, and the C.I. was higher than SV. 2) Type D was the dehydration type where the PWP and C.I. were lower than SV. 3) Type O was the overhydration type where the PWP and the C.I. were higher than SV. 4) Type C was the cardiac failure type where the PWP was higher, and the C.I. was lower than SV.
2. Type H was most common. During H.D. treatment there were no severe changes in theses cases with type H. In type D, hypotension often occured during H.D. In type O and C, edema was almost always observed in which the condition improved after H.D. treatment.
