Laboratory Studies

Fresh bite wounds without signs of infection do not need to be cultured. Infected bite wounds should be cultured to help guide future antibiotic therapy.

Other laboratory tests are indicated as the patient's condition dictates (eg, CBC and blood cultures for patients with sepsis).

If C canimorsus sepsis is suspected, examine the peripheral smear for the organism, a bacillus.

Imaging Studies

Radiography is indicated if any concerns exist that deep structures are at risk (eg, hand wounds; deep punctures; crushing bites, especially over joints).

Occult fractures or osteomyelitis may be discovered.

Radiographs may find foreign bodies in the wound (eg, teeth).

Children who have been bitten in the head should be examined for bony penetration with plain films or CT scan. If the child was shaken, consider cervical spine evaluation.

Animal bites. The devastating damage sustained by a preadolescent male during a dog attack. Almost lost in this photograph is the soft tissue damage to this victim's thigh. This patient required 2 units of O- blood and several liters of isotonic crystalloid. Repair of these wounds required a pediatric surgeon, an experienced orthopedic surgeon, and a plastic surgeon. Attacks such as these have caused a movement in some areas of the country to ban certain dog breeds.
Animal bites. Massive soft tissue damage of the right leg caused by a dog attack. This patient was transferred to a level one pediatric trauma center for care. At times, staff members may need counseling after caring for mauled patients.
