Snake Bites

People who regularly visit wilderness spots and wildlife areas, as well as those who go out camping, hiking, picnicking or even live in snake-infested zones, should certainly be aware of the potential dangers lurking out there, mostly posed by venomous snakes. According to the American Red Cross, a bite from a venomous snake, in which the concerned snake may inject varying degrees of venom into the person’s body, must always be considered as a medical emergency.

Every state with the exception of Alaska, Hawaii and Maine is home to at least one of the 20 domestic species of poisonous snakes. Estimates show that anywhere between 7,000 to 8,000 people get bitten by poisonous snakes in the United States each year. Since most snakebite victims are not experts on the subject and cant always identify the snake that bit them, they should seek immediate care for any kind of bite, even if they suspect the snake to be non-poisonous. Remember that even a bite from an apparently ‘harmless’ snake can cause some very severe allergic reactions in many individuals.

When it comes to treating snakebites, there have been many different theories out forth by medical professionals all over the world. Some professionals prefer to keep immediate treatment for later, while opting for observing the patient’s reaction and symptoms to gauge for the seriousness of the bite. Medical procedures like the fasciotomy, which is the surgical treatment of the surrounding layers of tissue around the bite has a lot of supporters. But the most popular form of treatment that doctors all around the world turn to is using an antidote to the snake venom, or antivenin, which is a very reliable treatment option for the more serious bites.

There are two basic types of antivenin or antivenom treatments being used today. Antivenin is derived from the antibodies that are created in the blood of horses or sheep when the concerned animal is injected with poisonous snake venom. In humans, antivenin can either be injected directly into the veins or in the muscles and it helps by neutralizing the venom that has entered the body. Because antivenin treatments are derived from horses, those snakebite victims who are more sensitive to horse proteins should be managed carefully. The danger lies in the fact that they could develop an adverse reaction to the medication or in some cases, a potentially fatal condition called anaphylactic shock.

Types of Venomous Snakes

There are two families of poisonous snakes in the United States. The vast majority however are the pit vipers that include copperheads, cottonmouths and rattlesnakes. These snakes inject venom through the two fangs that can be retracted by the snake when it is resting, and can spring rapidly back into biting position when it is under attack, or feels threatened. Virtually all the snakebites that have been reported in the United States are from pit vipers.

Some canebrake rattlesnakes or Mojave rattlesnakes carry neurotoxic venom that affects the spinal chord and the brain. Copperheads however, carry a less dangerous and milder venom. The other family of poisonous snakes is the ‘Elapidae’ that include two different species of coral snakes. Related to the more dangerous Asian kraits and cobras, coral snakes have shorter fangs. However, pit viper bites and coral snake bites can be treated effectively with antivenin. But many factors like time elapsed after being bitten and the care taken before the patient arrives at the hospital, are also critical.

Giving First aid for Snakebite Victims

In the last few years, snakebite victims have been subjected to all sorts of freezing, squeezing and slicing, as makeshift measures before the patient receives medical care. Some of these measures however, like attempting to suck the venom out or cutting into the bite, have fallen out of favor. These approaches cause more harm than good.

Most medical professionals embrace only a few basic first-aid methods. The following steps should be taken when you or someone you know has been bitten by a snake:

• Wash the area thoroughly with soap and water.
• Immobilize the area and keep it lower than the heart area.
• Get medical attention as soon as possible.

The main idea is to get the person to a hospital without any delay. If however, you cannot reach the hospital within 30 minutes of the attack, the wrap a bandage at least 2-4 inches above the bite, so as to slow the spread of venom. However, the bandage should not be so tight that it cuts off the blood flow entirely. The best thing is to make the band loose enough so that you can slip a finger under it. A suction pump can be placed over the bite to draw out small quantities of the venom without making any cuts.

How to Avoid Snakebites

Some snake bites, especially those that take place when a person accidentally steps on the snake, are practically impossible to prevent. But there are a few precautions that one must take to lower the risk of being bitten:

• Foolish as it may sound, leave them snakes alone! Most people get bitten when they try to get a closer look at the snake or when they are trying to kill it.
• Steer clear of grassy areas where the grass is very tall, unless you are wearing thick leather boots.
• Keep your feet and hands out of areas that you cant see. Don’t pick up firewood and rocks.
• Be alert and cautious when climbing rocks.
• If you encounter a snake when picnicking or hiking, just keep some distance from the snake, walk around it while giving it a little space – six feet is just right.

What NOT to do when treating a Snakebite
Although medical professionals don’t generally agree on every single aspect of what to do when treating a snakebite, they are however unanimous in their views of what not to do when treating a snakebite.

Do not put any kind of cooling agent like ice on the bite, as this is very harmful for the victim. Do not tie a tourniquet around the bitten area, as it cuts off the blood flow completely and could also result in the loss of a limb. No giving the victim electric shock treatments, as it could cause more harm.

Lastly, it is advisable to stay away from making any kind of incisions in the wound, as these measures tend to cause further injury.
