[Poisoning caused by the organophosphate parathion (E-605)]

In a 41-year-old patient administration of 5 g parathion led to respiratory failure and unconsciousness. Ventilatory support and antidote therapy were initiated early. However, only extensive gastric lavage and lowering of the plasma concentration by hemoperfusion with activated carbon resulted in the crucial elimination of the poison. Antidote and supportive measures may overcome the hazards of cholinesterase-inhibition, but not the direct toxic effect on the cardiovascular system which is currently regarded as the predominant cause of death.
