Bottle it up: Prehospital management of an AV fistula bleed using a bottle cap.

Hemorrhage from arteriovenous fistula sites is a known complication with potentially fatal consequences. The management of AV fistula hemorrhage has historically included direct pressure, tourniquet use, and/or surgical management. We describe a case of a 71-year-old female with hemorrhage from an AV fistula site that was successfully managed in the prehospital setting using a simple bottle cap.
