| − | In a snakebite situation, every reasonable effort should be made to kill or at least to positively identify the culprit, since treatment of a nonpoisonous bite is far simpler and less dangerous to the victim than treatment of a poisonous bite.
| + | <big>'''First Aids after a Snake bite:'''</big> |
| | | | |
| − | Snake venom is a complex mixture of enzymes, peptides, and other substances. A single injection can cause many different toxic effects in many areas of the body. Some of these effects are felt immediately while the action of other venom components may be delayed for hours or even days. A poisonous bite should be considered a true medical emergency until symptoms prove otherwise.
| + | '''Dos''' |
| | | | |
| − | The venom is stored in sacs in the snake’s head. It is introduced into a victim through hollow or grooved fangs. An important point to remember, however, is that a bitten patient has not necessarily received a dose of venom. The snake can control whether or not it will release the poison and how much it will inject. As a result, while symptoms in a poisonous snakebite incident may be severe, they may also be mild or not develop at all.
| + | * Snakes bite generally in hand or leg. Tie both ends of the bite with a rope or a piece of cloth. |
| | + | * Make a small cut with a clean razor so as to allow contaminated blood to flow out. |
| | + | * Watch the snake closely, so as to be able to describe it in front of the Doctor. |
| | + | * Rush to the hospital. |

| − | It is essential that you be able to quickly diagnose a snakebite as being envenomated or not. Usually enough symptoms present themselves within an hour of a poisonous snakebite to erase any doubt. The victim’s condition provides the best information as to the seriousness of the situation. The bite of the pit viper is extremely painful and is characterized by immediate swelling and excess fluid about the fang marks, usually within 5 to 10 minutes, spreading and possibly involving the whole extremity within an hour. If only minimal swelling occurs within 30 minutes, the bite will almost certainly have been from a nonpoisonous snake or from a poisonous snake that did not inject venom.
| + | '''Don'ts''' |

| − | The aim of first aid for envenomated snakebites is to reduce the circulation of blood through the bite area, delay absorption of venom, prevent aggravation of the local wound, maintain vital signs, and transport the victim as soon as possible to a medical treatment facility. Other aid will be mainly supportive:
| + | * Do not panic. Remember 97% of the snakes are not poisonous to the human beings. |
| − | | + | * Do not tie the cloth very tightly as it may lead to blood clotting in the area. |
| − | #Apply a constricting band (i.e., rubber tubing, belt, necktie, stocking) above and below the bite. Each band should be approximately 2 inches from the wound, but NEVER place the bands on each side of a joint. If only one constricting band is available, place it above the wound. It should be tight enough to stop the flow of blood in the veins, but not tight enough to shut off the arterial blood supply. The victim’s pulse should be palpable below the band.
| + | * Do not let excessive blood to flow out of the cut. |
| − | #If the victim cannot reach a medical treatment facility within 30 minutes of the time of the bite, and there are definite signs of poisoning, use a sterile knife blade to make an incision about 1/2 inch (13 mm) long and 1/4 inch (6 mm) deep over each fang mark on the long axis of the extremity. This technique is done only on the extremities, not on the head or trunk. Apply suction cups to help remove some of the injected venom. Suction by mouth is recommended only as a last resort, because the human mouth contains so many different bacteria that the bite could become infected. Incision and suction later than 30 minutes from the time of the bite is not recommended.
| + | * Do not try to clot the wound. Do not apply anything over it. |
| − | #Check the pulse and respiration frequently. Give artificial ventilation if necessary.
| + | * Do not try to treat with local remedies. Rush to hospital immediately after first aid. |
| − | #Calm and reassure the victim, who will often be excited or hysterical. Keep the victim lying down, quiet, and warm. '''DO NOT''' give alcohol or any other stimulant to drink.
| + | * Do not attempt to Fight the snake off. This will just make it more aggrivated! |
| − | #Treat for shock.
| |
| − | #Use a splint to immobilize the victim’s affected extremity, keeping the involved area at or below the level of the heart.
| |
| − | #Cover the wound to prevent further contamination.
| |
| − | #Give aspirin for pain.
| |
| − | #Telephone the nearest medical facility so that the proper antivenin can be made available.
| |
| − | #Transport the victim (and the dead snake) to a medical treatment facility as soon as possible. All suspected snake bite victims should be taken to the hospital, whether they show signs of envenomation or not.
