Dealing with Snakes in KZN Recently on an internet interest list, SA Mountain Talk, Arthur Morgan published this most useful and informative article on snakes in South Africa - and KZN. From the venom point of view there are four types of snakes in South Africa: Adders ( vipers) Mambas and Cobras ( plus sub-type Spitting Cobras ) Back fanged ( including sub-type Boomslang ) Constrictors ( no venom, but nasty wounds - treat as for dog bite ) All outdoors people are at risk for snake bite, although this occurs rarely in South Africa. Be careful where you walk and put your hands. If you see a snake freeze, and then move slowly away without any sudden movements. If you or a friend are bitten do not panic. Very serious injury is rare after a snake bite. The snake has to expend a lot of energy to make the venom, and will not use it wastefully - you are far to big for it to eat, and it just wants to warn you off with the least effort and risk to itself. It will inject a lot of venom only if you have made it very cross or very frightened. The most bites in Africa are by the adders, which are fat, lazy snakes that stay put on warm paths or where ever they want. If annoyed they can strike forwards with great speed. They have long fangs and inject a venom that causes tissue damage. There will be rapid onset of severe pain, needing big doses of morphine type analgesics, and gross swelling. The fluid and blood causing the swelling comes initially from the blood so there can be lethal shock. Treatment is elevation of the bite, fluid and blood as needed, lots of analgesia, and possibly several ampoules of anti venom. The time to death will usually be at least hours. | |
