Cases of fatal poisoning in post-mortem examinations at the Institute of Forensic Medicine in Greifswald-analysis of five decades of post-mortems.

摘要

Apparently, fatal poisoning as cause of death are still rarely found in unnatural deaths investigated in the institutes of forensic medicine. In the Institute of Forensic Medicine at the University of Greifswald, 10-15% of the post-mortem autopsies displayed an intoxication during the last several decades with a possible decreasing tendency. Thirteen thousand eight hundred and nineteen autopsies were carried out in our institute-situated in a low populated rural area-during the last 50 years with the confirmed death cause intoxication in 1,589 times. In this study, especially the intoxication causes and the substance classes of the poisonous agents have been investigated. In addition, we analyzed the frequency of intoxications as well as sex and age of the deceased. Surprisingly, CO-intoxications were found most frequently with an incidence of 49% followed by alcohol intoxications with 21%. The latter was not unexpected taking into account the habits of the local population. Medical drugs and narcoticstake only the third place, although the abuse of modern narcotics drugs is already visible even in the far east of Germany. The spectrum of substances which are abused, taken accidentally or deliberately is continuously changing, reflecting scientific progress in the pharmaceutical industry as well as fashion tendencies. Therapeutic use is almost always followed by abuse. Our results confirm prior experience concentrating mostly on other poisons like heavy metals or herbicides, etc. In addition, we could demonstrate the influence of political conditions on use and distribution of illegal drugs in Germany. Our study clearly demonstrates that insufficient equipment or analytical methods are no longer the reason for any problems uncovering lethal intoxications. They are rather due to insufficient investigations of the corpses (without considering the possibility of an intoxication as differential diagnosis) and to frequent mistakes of the prosecutor's office in death without signs of physical violence. These facts may explain the above mentioned decreasing tendency of intoxications, but they also clarify that this tendency probably does not correspond to reality.
