An experimental study on CAVH (continuous arteriovenous hemofiltra tion)

Abstract

The efficacy of CAVH in removing the excess water was investigated using mongrel dogs. Following the ligation of ureters, the dog received saline intravenously. Then pumpless CAVH was performed. The changes in serum protein level, CVP and muscle water content indicated the improvement of pathological overhydration with CAVH. The sieving coefficient (SC) of Na, K and Cl was almost 1,
and that of BUN and creatinine was 0.9. SC of total protein, however, was 0. These results indicate that CAVH is effective to remove the excess water improving the symptoms caused by it.
