Abstract
Three types of microencapsulated activated charcoal were tested. Unlike activated charcoal in the free form, the microencapsulated form did not give off embolizing particles. Heparin-complexed or albumin-coated collodion microencapsulated activated charcoal did not lower the arterial platelet level. Albumin-coated collodion microencapsulated activated charcoal was more efficient than the heparin-complexed form in lowering the blood creatinine level.
