[Multidrug intoxication].

The authors report an suicide attempt by a 43 years old woman treated by Previscan, Effexor, Rivotril, and Stilnox for phlebitis anteriority and anxious-depressive disorders. On arrival to the emergency unit, the medical status and the patient history required a cardiovascular reanimation and gastric washing. The haemostasis analysis demonstrates an anticoagulant overdose and the prescription of vitamine K1 and PPSB was necessary. Later, the multidrug poisoning was demonstrated thanks to blood, urinary and gastric fluid high performance liquid chromatography toxicological analyses. This case report points out that biological and toxicological analyses are complementary. The first ones are useful to determine the emergency symptomatic cares, and to check the drugs' efficiency. The second ones, although longer, are necessary to identify with certainty incriminated drugs.
