Biochemical correlates of reversal of hepatic coma coated with charcoal hemoperfusion.

Ten patients in stage IV hepatic encephalopathy who had not responded to conventional therapy for at least 48 hrs were treated with one or more 4 hr periods of hemoperfusion. Nine (90%) awoke, and 4 (40%) are alive to date, the survivors having acutely toxic and infective hepatic lesions. Biochemical changes that occurred were a reduction in blood ammonia of 23%, a rise in the ratio of branched chain to aromatic amino acids in blood (1.08 +/- 0.3 to 1.3 +/- 0.4), and cerebrospinal fluid (0.26 +/- 0.02 to 0.32 to 0.03), and a rise in cerebrospinal fluid cAMP from 2.3 +/- 0.7 ng/ml to 3.4 +/- 1.29 ng/ml with hemoperfusion. Administration of platelets and fresh frozen plasma restored the reduction of platelet counts of 29% towards pretreatment values.

Treatment of severe drug overdosage with charcoal hemoperfusion.

Mortality from severe poisoning remains excessively high in patients managed conservatively. In this report, charcoal hemoperfusion was used as a therapeutic aid to active drug removal in 10 patients (9 of whom were in Grade IV coma) intoxicated with a variety of drugs and a further 3 patients poisoned with the highly lethal herbicide, paraquat. All 10 patients who ingested drugs recovered. One of the 3 patients ingesting paraquat survived. The hemoperfusion treatments were associated with demonstrated drug removal. Complications associated with hemoperfusion were minor. Decreases in platelet levels were observed but were not accompanied by clinically important bleeding. The technique of hemoperfusion is simple and provides a therapeutic aid in the care of the severely poisoned patient.
