Antimicrobial prophylaxis for wounds and procedures in the emergency department.

Emergency physicians are often confronted with situations in which a patient with an acute injury is at high risk for an infection.

This article reviews antimicrobial wound infection prophylaxis for high-risk traumatic wounds, including the prevention of rabies and tetanus. Prophylaxis to prevent infections related to invasive procedures in the emergency department is also addressed.
