Snake bite commonly results in puncture wounds , which are inflicted by the snake’s fangs. Most of the times, snakes kill their victims with constriction around the chest causing cessation of breathing and heart rate. Many of the times the snakes are non-venomous snakes. Snakes inhabit every continent except for Antarctica. A bite from poisonous or venomous snake can be lethal and needs prompt medical attention. A bite from a harmless or non-venomous snake can also be serious, resulting in a severe allergic reaction or infection. The symptoms produced from a venomous snake bite range from localized swelling, pain, nausea, convulsions and paralysis.
First aid measures, which should be undertaken after being bitten by a snake includes, remaining calm, cleaning the bite region and immobilizing the bite area. However, it is important to transfer the bite victim to emergency care for treatment. The prognosis for a snake bite, if treated on time, is good.

Majority of the snakes in America are not venomous, but there are several types of them which are. Barring the coral snake, all the snakes are pit vipers, which can be identified by a depression or a pit between the eye and the nostril. Triangular head is another distinguishing factor of the pit vipers.

- Never raise the bite region above the victim’s heart. Keep it below the level of the heart.

Treatment For Snake Bite
A snake bite can be life threatening. The important thing to do in a situation like this is to get the victim immediately to emergency care as soon as possible. The doctor will assess the patient to decide on the right course of treatment. The severity of the condition depends on the location of the snake bite, victim’s age and health. If the snake bite is not serious, then the doctor will just clean the wound and give a tetanus vaccine to the victim.
In case the snake bite is life threatening, then the doctor will administer anti-venom, which is made from the snake venom to neutralize the symptoms. The anti-venom is given intravenously. The earlier the anti-venom is given for a snake bite, the more effective its effect will be.
How To Prevent Yourself From A Snake Bite?
In many cases snake bites can be prevented. Avoid getting close to snakes or touching them when you are in the wild. Refrain from going to areas, which have tall grass and piled leaves. Do not go near or lift woodpiles or rocks. These are some of the common places where snakes like to hide. If you have to work outdoors where snakes are present then wear leather gloves, long boots and long pants. Try not to work outside during warm weather and at night time, as this is when snakes are most active.
To cut down on your risk of getting snakebite, avoid touching any type of snake. If you come across a snake, slowly back away. Majority of the snakes avoid people and bite only when they are surprised or threatened.
What Is The Prognosis For A Snake Bite?
The prognosis depends on the type of the snake and patient’s age and general health; and for this reason, the prognosis of a snake bite differs from person to person. The prognosis in case of a non-venomous snake bite is very good, if the bite area is cleaned thoroughly and treated immediately. In case of a venomous bite, the prognosis depends on how soon the patient receives treatment. The sooner the treatment is started, the better the prognosis. Prognosis is better for healthy adults who have shallow snake bites when compared to snake bites on children and elderly with weakened immune systems and who have had a deep snake bite.
