A review of 157 cases of acute poisoning admitted to the intensive care unit shows that poisoning was responsible for 40 15% of the cases treated at this unit between 15th January to 31st December, 1976. Inspite of limited facilities the over all mortality from acute poisoning was 9.5% while that due to organo-phosphorus insecticides alone was 7%. A considerable infrequency of organophosphorus insecticides poisoning was observed in developed countries when their data was compared with the present series.
