Poisoning with salicylic acid and its derivatives is a quite common event, leading to possibly life-threatening complications. A case of fatal intoxication of a sixty-year old patient with acetylsalicylic acid is described and the therapeutic options are discussed. In acute poisoning it is mandatory to initiate simple and effective measures first. This gives time for discussing and planning the more laborious procedures. The initial treatment of salicylate poisoning is based on the prevention of further absorption by a sufficiently large quantity of orally administered activated charcoal (approximately 1 g/kg b.w.). Given repeatedly, activated charcoal may enhance non-renal clearance of salicylates. Intravenously administered sodium bicarbonate counteracts the metabolic acidosis. Moreover, bicarbonate therapy limits tissue distribution of the drug and enhances its renal excretion. The availability of glycine for salicylic acid metabolism may be limited in poisoning because glycine has been used for forming the conjugation product salicyluric acid. Glycine may be administered orally to overcome this bottleneck. Gastric lavage has been proven to be of limited efficacy. This efficacy is further diminished if gastric lavage is performed late after drug ingestion. When it is performed, however, activated charcoal should be administered before and after gastric lavage. Whenever the more simple treatment options fail, hemodialysis or hemoperfusion should be additionally considered since these procedures are effective in removing salicylates from the body. |
