Forced alkaline diuresis or hemodialysis is indicated in severe salicylate poisoning to remove unabsorbed drug. Other treatment modalities in salicylate poisoning are external cooling and intravenous fluids with sodium, potassium, bicarbonate and glucose. Gastric lavage is done to remove the unabsorbed drug. Blood transfusion and vitamin K is given if bleeding occurs. Fatal dose in salicylate poisoning is 15-30gm. Serious toxicity occur at serum salicylate levels >50mg/dl. Manifestations include vomiting, dehydration, acidotic breathing, hypoglycemia, delirium, hallucinations, convulsion, coma and death due to respiratory failure and cardiovascular collapse.
