Prophylactic Antibiotics for Open fractures
Initiate as soon as possible; increased infection rate when delayed[1]
Grade I & II Fractures Options
- Cefazolin 2 g IV (immediately and q8 hours x 3 total doses) (Ancef)[2]
- Cephalosporin allergy: Clindamycin 900 mg IV (immediately and q8 hours x 3 total doses)[2]
Grade III Fracture Options
- Ceftriaxone 2 g IV (immediately x 1 total dose) PLUS Vancomycin 1 g IV (immediately and q12 hours x 2 total doses)[2]
- Cephalosporin allergy: Aztreonam 2 g IV (immediately and q8 hours x 3) PLUS Vancomycin 1 g IV (immediately and q12 hours x 2 total doses)[2]
Special Considerations
- Concern for clostridium (soil contamination, farm injuries, possible bowel contamination): additionally add penicillin[3][2]
- Fresh water wounds: fluoroquinolones OR 3rd/4th generation cephalosporin
- Saltwater wounds (vibrio): doxycycline + ceftazidime OR fluoroquinolone
