[Emergency toxicology: analytic protocol applicable to biolobic media in tentative autolysis].

Here is exposed a method to detect and identify, without delay and in biological media, toxic substances generally found when attempting autolysis. It implies: 1; coloured reactions performed directly or after having isolated the substances using organic solvants, 2; thin layer chromatographies of these extractums which are developed and revealed in very precise conditions. Techniques for titration of some drugs are exposed. 253 cases of toxic coma have been studied, and the results of this inquiry analysed, more particularly cases induced by barbiturates.
