This step-by-step outline on the surgical treatment of canine bite wounds supplements the Consultant on Call Bite Wounds, which reviews and describes details and tips on presentation, medications, and follow-up.

Bite wounds, a common emergency presentation, can often be deceiving. When treating canine bite victims, it is important to consider the iceberg effect, in which minimal surface damage may disguise expansive damage underneath the skin. Patients that appear stable at initial presentation may present days later with systemic inflammatory response syndrome (SIRS) or sepsis.

Step 1.

Always wear gloves when working around a wound. Prepare a large area for surgery, as tissue damage is commonly more widespread in the deeper aspect of the bite wound than on the surface. Administer time-dependent antibiotics (eg, cephalosporins, augmented penicillins) IV q90min during surgery.
