We tested 289 envenomations. After treatment, 19% of treated patients had undesirable events, all benign. A possible adverse effect was attributed to this antivenom in 11% of the patients. Bleeding was observed in 48% of the patients; it stopped within 2 hours after treatment with antivenom in 60% of the patients. Blood incoagulability was observed in 80% of the patients. Restoration of coagulation was attained within 4 hours in 60% of the patients. Nine patients died; 6 arrived at the hospital in the final stage of complications and 5 arrived at the hospital more than 60 hours after the bite. The value of blood coagulation tests in diagnosis of envenomation and bleeding as an indicator of renewal of treatment are emphasized. specialized 050 77 3 538-546 2007 0002-9637 https://www.documentation.ird.fr/hor/fdi:010040789 0002-9637 [F B010040789] https://www.documentation.ird.fr/hor/fdi:010040789 https://horizon.documentation.ird.fr/exl-doc/pleins_textes/divers20-08/010040789.pdf IRD - Base Horizon / Pleins textes 2007-11-06 2020-09-17 fdi:010040789 fre
