In the US, pressure immobolization is recommended for certain coral snake bites. It is not recommended for pit viper bites since it could increase local necrosis or compartment pressure. Because treatment measures may differ from snake to snake, identification is important.

1. Myth- Mechanical suction, electric shock, and immersion in ice water are effective first aid (“field”) therapies for snakebite. In truth, these are not only not helpful, they may be quite harmful. Antivenom therapy is the only therapy that has been proven effective, with the possible exception of pressure immobilization for certain elapid (e.g., coral) snake bites.
