Answer

The initial assessment of an animal bite includes an estimation of the infection risk. Bites to the head and neck, to the distal extremities, and near joints carry the highest risk of infection. In general, persons with animal bite wounds are at a high risk for infection, especially those who present to medical attention more than 8-10 hours after the injury occurred.

Persons with underlying medical diseases, such as diabetes mellitus, chronic liver disease, asplenia, alcoholism, HIV infection, or other immunodeficiency conditions (including chronic steroid exposure), are at increased risk of infection.

After irrigation and cleansing, sharply débride nonviable tissue to reduce the risk of infection and to allow easier suturing by providing a more even edge.

Primary suturing of bite wounds is reserved for minor injuries, those at low risk for infection, and those that have been treated within 8-10 hours of injury.

Leave all other wounds open until the risk of infection is reduced by cleansing, debridement, and prophylactic antibiotics.
