In today's VETgirl online veterinary CE podcast, we review the use of antivenom in dogs. Is it worth the $500/bottle? How many bottles should we use? Is it necessary in all cases? So, we interview Dr. Daniel Foy, DACVIM, DACVECC, who published a study called "Retrospective evaluation of the effect of antivenom administration on hospitalization duration and treatment cost for dogs envenomated by Crotalus viridis: 113 dogs (2004-;2012)." This was a retrospective study looking at a large case population (over 100 dogs) who were envenomated with Crotalus viridis, or more commonly known as the prairie rattlesnake (which isn't as bad as other types of Crotalid species). In this study, it appeared that the use of antivenom did not positively affect outcome or duration of hospitalization, and actually increased costs! So, test your envenomation knowledge here in today's VETgirl podcast.
