Previously reported cases of suicide by intravenous barbiturates, as well as two other unusual cases [5,6], are compared in Table 2. All decedents were either medical or paramedical personnel and familiar with the drugs and the routes of administration used for their suicides. Lethal is used in veterinary euthanasia at an intravenous dose of 1 ml per 5 kg (10 lbs) body weight. Unconsciousness usually occurs during injection and death supervenes within a matter of seconds. The decedent in the present case weighed 90 kg (200 lbs) and had injected at least 40 ml of the drug, approximately twice the recommended lethal dose. There appears to be little doubt of the victim's suicidal intent, since he had used Lethal in his daily occupational duties. Additionally, the physical configuration of the supports devised to hold the syringe was quite stable, and injection stopped only when the decedent's hand came to rest upon the towels. To our knowledge, the present case represents the only one of its kind in the literature.
表2比较了先前报告的静脉注射巴比妥酸盐自杀案例以及其他两起罕见案例[5,6]。所有死者均为医务人员或医护辅助人员，熟悉用于自杀的药物和给药途径。“安乐死”用于兽医实施安乐死，静脉注射剂量为每5千克（10磅）体重1毫升。注射过程中通常会失去意识，数秒内就会死亡。本案死者体重90千克（200磅），注射了至少40毫升该药物，约为推荐致死剂量的两倍。受害者的自杀意图似乎毫无疑问，因为他在日常工作中使用过“安乐死”。此外，为固定注射器而设计的支撑结构相当稳固，只有当死者的手落到毛巾上时注射才停止。据我们所知，本案是文献中此类案例的唯一一例。
