76 Most Rattlesnake Envenomation Patients Receive Multiple Doses of Antivenom

Abstract

Antivenom is dosed to clinical effect. Previous reports from a smaller dataset showed that most patients envenomated by rattlesnakes require multiple doses of antivenom, regardless of whether they were treated with Fab or F(ab’)2 antivenom. This study expands previous work to incorporate 2020 data, and describes the dose and timing of both ovine Fab and equine F(ab’)2 antivenom administration for rattlesnake victims.
