What treatment would be given in an emergency room if someone is bitten by a rattlesnake and his friends have already applied ice packs to slow the spread of protein-based toxins?

Ice packs should never be applied to a rattlesnake bite. Applying ice to a rattlesnake bite can cause more harm than good. The venom from a rattlesnake bite is a protein, and proteins are not slowed down by cold temperatures. In fact, cold temperatures can actually cause the venom to spread more slowly, which can lead to more severe symptoms.

Instead of applying ice to a rattlesnake bite, the following first aid measures should be taken:

* Stay calm and try to keep the victim still.

* If possible, remove any jewelry or clothing that is tight around the bite area.

* Wash the bite area with soap and water.

* Apply a clean, dry bandage to the bite area.

* Immobilize the bitten limb.

* Seek medical attention immediately.

The venom from a rattlesnake bite can be very dangerous, so it is important to seek medical attention as soon as possible. If you are bitten by a rattlesnake, or if you know someone who was, do not delay seeking medical help.
