冷冻保存尸体对法医病理学鉴定的影响

Effect of Corpse Cryopreservation on Forensic Pathological Identification

由于冷冻保存能有效减缓尸体腐败进程、延长尸体的保存时间,已成为我国主要的尸体保存方式。然而此种保存方式会对尸体造成一定程度的非特异性影响而干扰法医病理学鉴定。本文收集、整理了国内外相关文献报道及实际鉴定中常遇到的相关问题,分别从解剖所见、组织形态学、死后生物化学、死后影像学等方面浅析冷冻保存对尸体的影响,以期对我国法医工作者在法医病理学实践过程中遇到的相关问题提供帮助。

Because cryopreservation can effectively slow down the putrefaction and prolong the preservation time of corpses, it has become the main way of corpse preservation in China. However, it may cause a certain degree of non-specific effects on the corpses and thus interfere with forensic pathological identification. This paper summarizes relevant problems reported in domestic and foreign literature reports and practical identification, and analyzes the effects of cryopreservation on corpses from aspects of anatomical findings, histomorphology, postmortem biochemistry, and postmortem imaging, therefore to provide Chinese forensic workers assistance on problems in their practice of forensic pathology.
