Get familiar with the algorithm, and let it help guide you in the event of a snakebite

The unified treatment algorithm is a comprehensive procedure based on expert recommendations for proper treatment in the event of a pit viper snakebite.

This information is adapted from general advice from a panel of US snakebite experts convened in May 2010. No algorithm can anticipate all clinical situations. Other valid approaches exist, and deviations from this information based on individual patient needs, local resources, local treatment guidelines, and patient preferences are expected. This algorithm is not intended to represent a standard of care. For more information, please see the accompanying manuscript, available at

Watch Dr. Eric Lavonas break down the reasoning behind the unified treatment algorithm.

Did You Know?

It has been estimated that 7,000-8,000 people are bitten by venomous snakes per year. The number of morbidities can be decreased with preparation for aggressive and immediate medical intervention.1
