[Cyanide poisoning: forensic toxicology observations in the study of 54 cases of fatal poisoning]

Abstract

The present study describes various observations made during the examination of 54 cases of lethal cyanide intoxication at the Institute of Forensic Medicine of the University of Zürich during a period of more than 40 years. Data pertain to the scene of death, the medicolegal inspection, the autopsy, the histological examinations, the chemical analyses, the various types of poisoning observed and the diagnostic criteria used. The intoxicated victims were mostly adults who had professional access to various cyanogenic compounds and had ingested them with the intention of committing suicide. Cases of accidental and criminal poisoning were rare. In spite of this fact, and although its frequency has not increased in the last few decades, cyanide poisoning has maintained undiminished importance.
