Abstract
BACKGROUND: In southwestern Colombia there is a notable variety of snakes that belong to the Viperidae family (vipers). The particular clinical manifestation related to species is poorly reported. METHODS: Based on a prospective study about envenomation caused by vipers from 2011 to 2019 at the Fundación Valle del Lili Hospital, Cali, in southwest Colombia, we selected cases of admitted patients in which the snakes responsible were fully identified. They were cataloged by clinical syndrome according to prevalent signs (edema-inducing, necrotizing, blister-inducing, procoagulant, anticoagulant or myotoxic) and were related to the species that caused the envenomation. RESULTS: From a cohort of 53 patients, 21 patients (16 males [72.7%]) with an average age of 35 (3-69) y were included. The syndromes associated with envenomation were anticoagulant and necrotizing effects of Bothrops asper (five patients [22.7%]), blister-inducing and anticoagulant effects of Bothrops rhombeatus (five [22.7%]), anticoagulant effects of Bothrops punctatus (three patients [13.6%]), edema-inducing and anticoagulant effects of Bothriechis schlegelii (five [22.7%]), edema-inducing and myotoxic effects of Bothrocophias colombianus (one [4.5%]), edema-inducing and myotoxic effects of Bothrocophias myersi (one [4.5%]) and edema-inducing effects of Porthidium nasutum (one [4.5%]). CONCLUSION: In southwestern Colombia there is notable variety in species of snakes belonging to the family Viperidae (vipers) whose envenomation causes various clinical syndromes.
