[Continuous haemofiltration in encephalopathy associated with hepatic failure (author's transl)].
Thirty-one comatose patients (18 with cirrhosis of the liver, 13 with severe hepatitis) were treated with continuous haemofiltration on polyacrylonitrile membrane (AN 69). The mean duration of sessions was 45 +/- 37 h, during which 136 +/- 108 1 of ultrafiltrate were dialyzed. Sixteen patients emerged from coma, 14 (7 with cirrhosis, 7 with hepatitis) completely and 2 partially. Blood ammonium levels decreased by 47 +/- 21% during the first 24 hours. Aminoacid clearance ranged from 20 to 50 ml/min, but only non significant changes were observed in the branched-chain/aromatic aminoacid ratio. Provided the haemodynamic balance is preserved, the technique is well tolerated. The duration of dialysis depends upon the degree of thrombopenia induced. Since the long-term prognosis of both cirrhosis patients and severe hepatitis patients is unmodified, continuous haemofiltration can only be helpful in cases where hepatic regeneration is possible; failing this, liver transplantation should be considered.
