NECROPSY STUDY OF MECHANICAL ASPHYXIAS (Abstract): Mechanical asphyxia represents a major issue in forensic medicine and is a phenomenon generally associated to oxygen deprivation due to various causes such as strangulation, suffocation, entrapment, trauma, or drowning. Asphyxia as a cause of death is a complex diagnosis due to the absence of specific signs. The aim of the current study is to identify the most frequent causes and mechanisms of asphyxias in the Romanian population from the region of Moldova. The authors performed a retrospective study at the Institute of Forensic Medicine from Iasi, Romania on 55 cases (39 males and 16 females) whose cause of death following necropsy and toxicological analysis performed between January 2015-December 2016 was mechanical asphyxia due to strangulation (37 cases – 67.27%), suffocation (11 cases – 20%), and drowning (7 cases – 12.73%). Most individuals (41 – 74.55%) were less than 60 years old (mean age 53.2 years), age being closely related to the cause of death. As signs of asphyxia, the authors discovered the presence of haemorrhagic infiltrates in the temporal, sternocleidomastoid and other accessory respiratory muscles, intervertebral haemorrhages (Simon’s sign), conjunctival petechiae and pulmonary congestion in most cases. A thorough analysis of laryngeal cartilages is mandatory when hanging is suspected. In conclusion, a systematic research and interpretation of key signs together with histopathological analysis leads to a specific diagnosis in case of death by mechanical asphyxia.
