Thiocyanate is an inorganic compound used in industrial applications. Here, we report a case of suicidal death due to acute thiocyanate overdose. A 44-year-old man who consumed an unknown amount of thiocyanate solution was transferred to the emergency room and died 2 h after admission. An autopsy was performed 2 days after death. General toxicological analysis of blood using gas chromatography-mass spectrometry (GC-MS) and liquid chromatography-tandem mass spectrometry found no drug or alcohol. Quantification using GC-MS post-derivatization with pentafluorobenzyl bromide revealed 2,290 and 1,920 mg/L of thiocyanate in the heart and femoral blood samples, respectively. Thus, the cause of death was attributed to thiocyanate overdose. This study provides useful information for the interpretation of thiocyanate-related fatalities.

气相色谱-质谱法检测硫氰酸钾中毒致死患者死后血液中的硫氰酸盐

硫氰酸盐是一种用于工业应用的无机化合物。在此，我们报告一例因急性硫氰酸盐过量服用而自杀死亡的病例。一名44岁男子因饮用了不明量的硫氰酸盐溶液，被送往急诊室，入院2小时后死亡。死后两天进行尸检。使用气相色谱-质谱（GC-MS）和液相色谱-串联质谱对血液进行一般毒理学分析，未发现药物或酒精。使用五氟苄基溴衍生化后的 GC-MS 进行定量显示，心脏和股骨血样中分别含有 2,290 毫克/升和 1,920 毫克/升的硫氰酸盐。因此，死亡原因归因于硫氰酸盐过量。这项研究为解释硫氰酸盐相关死亡事件提供了有用的信息。
