Snake Bites - First Aid and Prevention

As the climbing season in the Southwest goes through the high season of March and April, I am often asked about snakes. Are there snakes in Red Rock? Are there snakes in Joshua Tree? Are they dangerous?

The answer to all three questions is yes...and no. There are rattlesnakes in both Red Rock and Joshua Tree, but they are uncommon in both venues. Large populations of predatory birds help keep the snake populations low. It is unlikely that you will encounter a snake in either location. And even if you do, the likelihood of a problem with a snake is very low.

Statistically the mostly likely group of individuals to be bitten by a snake are between the ages of 15 and 25 years-old and are male. Most of these bites take place on the hands or forearms. I couldn't find any statistics about the involvement of alcohol in snake bites.

Based on my last sentence, what do you suppose such statistics suggest?

Yep, you guessed it. They're messing with them.

Millions of people live, work and play in the same places where snakes live, work and play. In the continental United States less than 8,000 people are bitten by snakes every year and as stated above, a large percentage of them are literally asking for it.

In the unlikely event that somebody in your party does receive a snakebite, don't panic and try to keep the victim calm. Many snakebites happen because the snake is defending itself. When a snake bites out of defense it is less likely to envenomate. So there is the possibility that there is no venom in the bite. So there may be nothing to panic about.

If there is venom in the bite, panicking will only raise one's heart-rate and allow the venom to move more quickly through the system. It is incredibly important to keep the victim calm. Remove any jewelry or rings from any extremity that has been bitten. If there is venom in the bite, there will be significant swelling -- so much that a ring could become stuck, cutting off blood flow and ultimately causing the loss of a finger.

In the old movies, John Wayne loved to cut open a snakebite to suck out the venom. John Wayne was apparently unaware of hepatitis, HIV, cytomegalovirus or any of a number of other blood-borne dangers. Doctors and nurses don't wear latex gloves for nothing. Sucking venom out of a wound flies in the face of a basic tenant of first aid, body substance isolation.

Obviously if someone is bitten by a snake, call for emergency assistance immediately. Responding quickly is crucial. While waiting for emergency assistance:
  • Wash the bite with soap and water.



  • Monitor vital signs.

If a victim is unable to reach medical care within 30 minutes, the American Red Cross recommends:

  • Apply a bandage, wrapped two to four inches above the bite, to help slow the venom. This should not cut off the flow of blood from a vein or artery - the band should be loose enough to slip a finger under it.

  • It is possible to place a suction deviceover the bite to help draw venom out of the wound without making cuts. These devices are often included in commercial snake bite kits. However, the value of these devices is debatable.

Physicians often use antivenin -- an antidote to snake venom -- to treat serious snake bites. Antivenin is derived from antibodies created in a sheep's blood serum when the animal is injected with snake venom. Because antivenin is obtained from horses, snake bite victims sensitive to horse products must be carefully managed.

The best way to avoid a snakebite is to avoid a snake. If you see one, don't mess with it. Both you and the snake will be much happier in the long-run.

Thanks for the advice regarding snake bites. I get asked about them on first aid courses in the UK.

I can now give sound advice.

I have done some researched and found some opinions from Australia, recommendations for increase blood flows, to keep the poison from damaging local tissue. There theory is spread it out over the body less harm. Have you heard of this?
