Abstract
A hemoperfusion system was developed which makes use of activated carbon encapsulated with cellulose acetate. Studies revealed that there are no stagnant flow regions in the column, there is minimal particle release and the coating is 30 .ANG. thick. The relationships between pore size, pore volume and surface area were examined. Twenty-five patients in grade IV coma were treated with the column for treatment of drug overdose or agricultural chemical poisoning. The clinical course of 1 meprobamate-poisoned patient was described in detail.Keywords
