Evaluation of a Treatment Algorithm for Tsushima Mamushi (Gloydius tsushimaensis) Snakebites, after Its Introduction to Tsushima Island, Nagasaki, Japan.

Objective Tsushima mamushi (Gloydius tsushimaensis) is an endemic species of snake inhabiting only Tsushima Island, a remote Japanese island. We conducted a multicenter, retrospective study of G. tsushimaensis bites for the first time and developed a treatment algorithm that unified treatment on the island and is still in use today.
