- In Colorado, the snake that people start worrying about in the spring and summer is that rattlesnake. However, 25% of bites are dry bites, meaning no venom, and there are only about 10 lethal snake bites per year in the US.
- The new anti-venom is CroFab, an immunoglobulin from sheep that has antibody to the toxin of the crotalinae. The anti-venom is expensive, but very safe for use.
- Swelling is generally the initial symptom; dangerous places include the hand and face. In the case of any significant swelling, get anti-venom treatment immediately.
- Treatment with anti-venom consists of 4-6 vials of antivenom then tracking swelling, and another dose of 4-6 vials if swelling continues within an hour.
- Rarely patients develop compartment syndrome, most resolve with antivenom and don’t need surgery
- In the United States, first aid is generally not needed as long as you keep calm and get to a hospital. It is even discouraged because it can cause more damage than benefits.
