In 56 patients with proven hump-nosed viper (Hypnale hypnale) bites, 12 (21.4%) developed continued oozing of blood from the site of the bite and a prolonged clotting time. Further investigations showed low fibrinogen levels and increased fibrinogen degradation products in plamsa. The bleeding time, platelet count, prothrombin time, and partial thromboplastin time with kaolin were normal. The bite of this snake can be complicated with a coagulopathy in which excessive fibrinolysis seems to be the main abnormality.
在56例已证实被尖吻蝮蛇（Hypnale hypnale）咬伤的患者中，12例（21.4%）出现咬伤部位持续渗血且凝血时间延长。进一步检查显示血浆纤维蛋白原水平降低，纤维蛋白原降解产物增加。出血时间、血小板计数、凝血酶原时间以及高岭土部分凝血活酶时间均正常。这种蛇咬伤可并发凝血病，其中过度纤维蛋白溶解似乎是主要异常情况。
