Snake bite is an injury caused by a bite from a snake, usually resulting in puncture wounds inflicted by the animal's fangs and sometimes resulting in envenomation.
The outcome of a snake bite depends on factors such as the species of snake, the area of the body bitten, the amount of venom injected and the health conditions of the person. Usually a person bitten by a snake goes through feelings of terror and panic, racing heart and nausea. Bites from non-venomous snakes can cause injury, due to lacerations caused by the snake's teeth or from a resulting infection. A bite may also trigger an anaphylactic reaction, which is potentially fatal.
- Puncture marks inflicted by the fangs
- Swelling or severe pain at the site
- Nausea and/or vomiting
- Numbness/tingling sensation
- Blurred or double vision
- Difficulty speaking and swallowing
- Weakness or paralysis of arms or legs
- Breathing difficulties
- Rest and reassure casualty continuously - un-necessary panic will only raise the pulse rate and blood pressure and move the venom into the circulatory system faster.
- Wash the wound with soap and water, pat dry DO NOT rub
- Immobilize the affected area
- Keep area below heart. DO NOT elevate the affected limb
- Get the casualty to a hospital immediately
- Do NOT cut or suck the bitten area
- Use pressure immobilization bandage: wide crepe bandage over bite, second pressure bandage upward from bite site towards heart
- Tie a band about 4 to 6" above bite towards heart
- Loosen band for a minute or two every 15 to 30 minutes
- If swelling extends to band, move band a few inches higher
- Do NOT let person walk, if need be carry him/her
