High volume plasma exchange in fulminant hepatic failure.
We investigated the effect of repeated high volume plasma exchange with fresh donor plasma in 11 patients with fulminant hepatic failure, all initially in stage 3 or 4 encephalopathy. A daily exchange of a volume equal to the extracellular volume (20% of body weight) on three consecutive days was intended. We obtained an average of 2.6 exchanges each with a mean volume equal to 16% of the body weight. Five patients (46%, 95% confidence limits 17%-77%) survived, all with acetaminophen induced liver failure. Four of the 6 non-survivors showed a temporary improvement in cerebral function. Two of the patients woke up completely. The 6 non-survivors maintained a stable condition with a systolic blood pressure > 110 mm Hg for a mean of 6.9 days after initiating plasma exchange. Plasma exchange may be considered in acute liver failure in patients with residual liver function before transplantation is finally decided. In addition, plasmapheresis may be used to keep patients with definite liver failure clinically stable until a transplant can be performed.
