To minimize the risk of developing an FRI and subsequent morbidity, prophylactic antibiotics should be administered to patients with open fractures as soon as possible. While the antibiotic recommendations for severe open fractures are somewhat debatable, the use of a cephalosporin remains a mainstay of prophylactic treatment. Though administration of prehospital antibiotics does represent an expansion of EMS responsibilities, there have been several other treatment expansions in the prehospital setting, such as the administration of tranexamic acid and the application of pelvic binders. The administration of antibiotics, specifically cefazolin, is inexpensive, technically simple, and does not require special storage. The following recommendations are supported by and represent consensus of the COT, OTA, ACEP, NAEMSP and NAEMT with regards to prehospital antibiotic prophylaxis for suspected fractures:In a responsive patient with no history of penicillin or cephalosporin allergy, the administration by EMS of a 1^st generation cephalosporin should be performed after the management of life threats.
