[Suspected poisoning and actual poisons found in chemico-toxicological emergency investigations (author's transl)].

In almost half (46.5%) of 400 chemico-toxicological investigations suspected poisoning had been assumed without a specific poison being named. In 73% of these cases toxicologically important substances were demonstrated. In 19% of cases no poison could be demonstrated and in approximately 6% of cases poison ingestion could neither be ascertained nor ruled out. In 53.5% of emergency investigations suspected poisons could be named before the beginning of analysis. The information could be verified partially or completely in 78%. In 20% of these more poisonous substances were found than suspected and in 16.3% none of the suspected substances but completely different toxic ones were demonstrable. In 5.6% of cases suspected poison ingestion could not be verified.
