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？

Its venom causes severe pain and swelling around the bite, and sometimes tissue damage (necrosis), where body tissue dies. The venom acts on platelets, the small cells that help blood clot, and can cause dangerous blood clots. Symptoms are described as developing over time after a bite.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。

In northern Malaysia it is responsible for about 700 snakebite incidents a year, with a mortality rate of about 2 percent. In a 2005 study of 145 patients in Thailand, 18.6 percent were left with permanently swollen limbs, and two patients died from brain bleeding. Many victims lose limb use or have limbs amputated when there is no antivenom or early treatment.1

好消息：医生有药（抗毒血清）或治疗方法。1

它害怕时会做什么？

It has a reputation for being bad-tempered and quick to strike when disturbed.1

如果它咬人

Get medical treatment as early as possible, as delays are linked to lasting limb damage. Antivenin is effective in reversing the blood clotting caused by the venom. Authors advise victims not to use traditional healers and to avoid overusing tourniquets.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

The venom of this snake is used to isolate an enzyme called ancrod, which doctors use to break down blood clots in patients.1

It is very sedentary, and has often been found in the same spot several hours after a bite involving a person.1

Bites happen throughout the year but mostly early in the monsoon season, in May and June.1

It is the only Asian pit viper with large crown scales and smooth back scales.1
