2017
AbstractBackground: Western Pygmy Rattlesnake (WPR) envenomation reportedly causes refractory and persistent coagulopathy when treated with CroFab® (Crotalidae Polyvalent Immune Fab). We report two cases where polyvalent equine anti-viper serum (AntivipmynTRI®) was used to treat recurrent coagulopathy in children.Case details: The first patient was a 16-month-old male who was bitten by a confirmed WPR. The patient received a total of 18 vials of CroFab®. His labs normalized, swelling gradually improved, and the child was discharged to home. On day 5, the child returned to the emergency department with a great deal of inguinal tenderness. Labs were obtained and the child’s INR was >13.1, while the fibrinogen was <60 mg/dL and the d-dimer was 11.72 mg/L. A decision was made to administer Antivipmyn TRI®, and the child received a total of 10 vials. Lab values significantly improved: INR 1.2, fibrinogen 93 mg/dL, and d-dimer 4.21 mg/L. The second patient was a 20-month-old male who presented following snake e...
