Ophidian accident is the injury resulting from a snake bite, in which if venom has been inoculated, local and/or systemic alterations will develop, these alterations are named ophidiotoxicosis. Worldwide, it is estimated that 5.4 million ophidian accidents are recorded each year, which generates between 81,000 and 131,000 deaths from ophidiotoxicosis. In Mexico, during 2019, 4,115 snake bites were registered, mainly affecting men, however, it is estimated that there is a considerable under-registration throughout the region. Huixquilucan is a municipality in the State of Mexico that is located west of Mexico City. Most of its territory is occupied by coniferous forests, so among the species of toxicological importance can be found viperids such as Crotalus ravus and Crotalus triseriatus, since this environment represents one of its main habitats. We report two pediatric cases with snake envenomation by Crotalus ravus in Huixquilucan at different times, which were successfully treated with fabotherapy.
