毒液之力

咬伤

它咬的时候，毒液通过毒牙或牙齿出来。

它的毒液会造成什么？

This snake is highly venomous. Its venom causes pain, swelling, bruising and necrosis (death of body tissue), and it can also lead to abscesses. The venom disturbs blood clotting: the venom has thrombin-like proteases, which slow the clotting of fibrinogen, a protein needed to form clots. Bites can also cause high blood pressure and collapse.1

它对人有多危险？

对人的危险: 非常危险不治疗可能会害死人。

This species is one of the main causes of snakebite in Argentina. Between 1960 and 1975, about 500 cases were reported there each year, and 80% of them were attributed to one subspecies, B. n. diporus. In a study of 18 bite cases admitted to a hospital in São Paulo from 1975 to 1992, all patients had pain, 83% had swelling, 50% had bruising, 17% had necrosis and 12% developed coagulopathy (a clotting disorder).1

好消息：医生有药（抗毒血清）或治疗方法。1

如果它咬人

Three antivenins made by the Instituto Butantan in Brazil can be used to treat bites from this species. Treatment with heparin might help the clotting problems caused by the venom.1
让人保持安静不动，被咬的肢体与心脏保持同一高度，摘下戒指和紧身物品，尽快送医院。

注意安全

永远不要摸、抓或逗弄野生动物，即使是很小的，即使它看起来在睡觉或已经死了。
给它留出空间。如果遇到它，保持冷静，慢慢后退，让它走自己的路。
如果被它咬了：保持冷静，保持不动，拨打你的急救电话（112、000、911）或尽快去医院。记住它长什么样，拍张照片会有帮助。

它不是冲着你来的。它用毒液捕猎或保护自己，而且它更愿意躲起来。更多安全知识

事实

In a case in Germany, a 36-year-old snake keeper was bitten on the finger. The bitten finger developed necrosis, and the swelling spread onto the hand.1

The average venom yield is 25 to 40 mg (dry weight).1
