[Acid-base modifications induced by treatment with concentration-reinfusion of ascitis fluid in cyrrhosis (author's transl)].

In 9 cyrrhotic patients with ascites we have studied the acid base status and the renal acidogenic capacity (urinary titrable acidity, ammonia) before, during and after reinfusion of concentrated ascitic fluid. Acid-base parameters have been evaluated also in the ascitic fluid and in the concentrated reinfusion fluid. The treatment does not determine any significant variation of acid base equilibrium in the cyrrhotic patients, while there is a remarkable loosing of CO2 with lowering of pCO2 in the concentrated ascitic fluid. We discuss the main physiopathological factors involved in such a type of treatment.
