Prevalence and Management of Snake Bite Envenomation at the Regional Hospital Center of Sokodé (Togo)

Abstract

Snakebite envenomation (SBE) is a public health issue in Africa, unfortunately neglected and underestimated. SBE is a medical emergency that can be devastating and lifethreatening. A retrospective study was performed from January 1, 2016 to December 31, 2016 in the general medicine department of the Regional Hospital Center (CHR), Sokodé. We included 91 SBE accounting for 5.7% of the whole hospitalizations in the general medicine department at the CHR of Sokodé. The median age of the patients was 34 [23.5-42] with male predominance (59%). Farming activities (75%) and walking (24%) were the most frequent activities when SBE happened, and they occurred mostly in rural areas (80%) during the dry season (56%). Echis genus (37%) belonging to the Viperidae family was the king of snake most often identified. Hospital admission time after a bite often exceeded 24 hours (44%). Clinical manifestations resulted in 76 cases of viper syndrome (83%) and 7 cases of dry bites (8%). Antivenom was administered in 84 cases (92%) within 12 hours (54%) after the bite with a minimum dose of 20 mL (43%). Observed complications were severe anemia (19 cases) and diffuse hemorrhage (32 cases). Case fatality rate was 9%. Antivenom is critical in cases of obvious SBE. High cost and poor access of antivenom, in addition to delayed care due to traditional treatment seeking behavior, are factors of poor prognosis.
