The authors of the present study conducted a prospective analysis at the University Hospital of Parakou (north of Benin) for seven months (January 1 to July 31, 2014) to assess the contribution of ultrasonography to the diagnosis of internal bleedings and management of envenomation. Methods: An ultrasound examination was performed in all patients with clinical envenomation regardless of its severity. The study involved 32 patients admitted to the ICU of the University Hospital of Parakou. Results: The average age was 27 +/- 13.9 years. The main signs of severity were: prolongation of clotting time (88 %), severe anemia (41 %), clinical hemorrhage (47 %), and shock (19 %). The ultrasound imaging showed internal hemorrhage in 18 patients (56 %). There were hematomas (22 %), hemoperitoneum (13 %) or a combination of both (22 %). The occurrence of internal bleeding and hemoperitoneum were mainly related to the delay of hospital presentation (p = 0.007) and the existence of external bleeding (p = 0.04). Thirty patients (94 %) received antivenom. Case fatality rate was 3.1 %. Conclusion: Ultrasonography may help in diagnosing internal bleeding, even in patients that did not show external hemorrhages, and evaluating its importance. As a consequence, the management of snakebite victims may be significantly improved. specialized Envenomation Ultrasound Internal bleeding Hemoperitoneum Hematoma BENIN 050 080 22 art. 13 [7 p.] 2016 1678-9199 International Conference on Envenomation by Snakebites and Scorpion Stings in Africa, 6., Abidjan (CIV), 2015/06/01-05 https://www.documentation.ird.fr/hor/fdi:010066738 10.1186/s40409-016-0063-x 1678-9199 [F B010066738] https://www.documentation.ird.fr/hor/fdi:010066738 https://horizon.documentation.ird.fr/exl-doc/pleins_textes/divers16-04/010066738.pdf IRD - Base Horizon / Pleins textes 2016-05-03 2018-06-28 fdi:010066738 fre
