Fatal sodium nitrite poisonings are rare in the forensic context. The present work describes a first fatal case of sodium nitrite contained in a suicide kit that the victim acquired over the internet. The results of the autopsy showed general signs of asphyxia, such as intense cyanosis of the extremities, brown-gray-blue-red livor mortis, and some Tardieu petechiae in addition to intense visceral congestion. It is clear that forensic experts must be aware of the proliferation of this market and the risks of improper selling of these substances through suicide support networks available on the internet. The lack of knowledge of this reality may become unidentifiable, when toxicological analysis contemplates only the most classical and frequent substances involved in poisoning and reinforce the importance of a careful analysis of the death scene.
在法医学领域，致命的亚硝酸钠中毒较为罕见。本工作描述了首例致命的亚硝酸钠中毒案例，亚硝酸钠装在一个自杀套件中，由受害者通过互联网购买。尸检结果显示出窒息的一般征象，如四肢强烈的青紫色、棕灰色-蓝色-红色尸斑，以及一些 Tardieu 瘀点，此外还有明显的内脏淤血。显然，法医专家必须意识到这种市场的扩散以及通过互联网上提供的自杀支持网络不当销售这些物质的风险。如果毒理学分析仅考虑与中毒有关的最典型和最常见的物质，而不了解这一现实，可能会导致无法识别，因此应加强对死亡现场进行仔细分析的重要性。
