title: Haemoperfusion ineffective for paraquat removal in life-threatening poisoning.
abstract: Five patients in whom plasma paraquat concentrations suggested that survival was in doubt were treated by charcoal haemoperfusion. The mass of paraquat removed was in each case between 2.5 and 19.1 mg. Three of the patients survived and two died. The mass of paraquat removed is low in relation to the adult lethal dose of 1000-3000 mg.
