Experience with activated carbon-bead haemoperfusion columns in the treatment of severe drug intoxication

Five patients who were severely poisoned with hypnotic drugs, paracetamol, or theophylline were treated by charcoal haemoperfusion. The device contained 160 g of activated carbon beads with a polyester coating. Four patients made a significant improvement; one subsequently died from a cerebral haemorrhage which had occurred prior to haemoperfusion. Platelet losses were minimal and no fibrinolysis was observed. No significant biochemical abnormality occurred as a result of haemoperfusion, although one patient, who presented with hypocalcaemia, required intravenous calcium throughout the procedure.
