Open fractures come in all shapes and sizes. Sometimes fractures create only a small, innocuous-looking puncture through the skin. Other times they look grossly contaminated with organic material and have significant soft tissue injury. The major concern is wound infection. Prophylactic antibiotics are essential in the ED.
Typically antibiotics are first-generation cephalosporins. When do you start adding more coverage with high-dose penicillin or aminoglycosides?
Pearl: Once you have significant soft tissue injury, you are automatically have a Type III open fracture and should add an aminoglycoside.

What do you mean by "continue abx x72 hrs post-injury or not >24 hrs after soft-tissue coverage achieved"?
ReplyDeleteExcellent question, Brian. I too paused for a bit on this wording. It's straight out of the EAST guidelines. My interpretation is: exchange "or" with "but". So give antibiotics for 72 hours post-injury BUT not to exceed beyond 24 hours after soft-tissue coverage. In the end, I didn't make a big deal of this, because if your patient is in the ED for that long, you have bigger problems to tackle.
