Tanatological assessment of long-brain structures in death from hemorrhagic shock at different post-mortal periods

Authors determined the morphological and morphometric characteristics of nerve and vascular structures in death from blood loss complicated by hemorrhagic shock. The medulla oblongata of 12 corpses of persons who died from stab wounds of blood vessels and internal organs with sharp instruments at different times of the postmortem period was studied. Studies were carried out at stages of 6-8 hours, 12-14 hours, 18-20 hours, 24 hours or more of the postmortem period. It was found that as the interval after death from hemorrhagic shock increases, there is an increase in destructive changes, both neurons and intracerebral vessels in the medulla oblongata. Autolytic processes to a greater extent capture the intracerebral vessels comparing with neurons, which is more pronounced in the later stages of the study. The sizes of perineural and perivascular spaces in the dynamics of the postmortem period increase synchronously, which reflects the permanence of manifestations of tanatogenesis in different periods after death from hemorrhagic shock.
