Follow-up

Further Inpatient Care

  • Patients with infected animal bites may need inpatient care. This depends on the general health of the patient, the extent and nature of the infection, and the patient's compliance.
  • Consider admitting patients with hand bites that become infected (generally involving deep structures). Consider consultation with hand surgery service if deep infection, such as involving the tendon sheath or other structures, is suspected as surgical irrigation may be indicated.

Further Outpatient Care

  • Close follow-up care is essential in animal bite wounds. Reevaluate a low-risk bite for signs of infection within 48 hours and a high-risk bite within 24 hours.
  • In some centers that have an observation unit, admission to that area for direct clinical observation and repeat doses of parenteral antibiotics can be considered on a case-by-case basis.

Transfer

  • Patients who require extensive repair or prolonged inpatient care may need transfer to a tertiary care facility.

Complications

Complications of animal bite wounds may include the following:

  • Wound infection
  • Sepsis
  • Cosmetic deformity
  • Loss of limb
  • Loss of function

Prognosis

  • The prognosis of animal bite wounds is generally excellent.

Patient Education

  • Educating patients about the risk of infection despite proper wound care, antibiotics (if indicated), and close follow-up care is very important. Even bite wounds that have received the best care may become infected. Teach patients the signs of infection and the need for prompt attention if the wound should become infected.
  • For excellent patient education resources, visit eMedicine's Bites and Stings Center and Bacterial and Viral Infections Center. Also, see eMedicine's patient education articles Animal Bites and Rabies.

Miscellaneous

Medicolegal Pitfalls

  • Meticulous documentation of both the history of the bite and of treatment is important to prevent questions about the appropriateness of care. Documentation should include a thorough assessment of neurovascular and functional status, evidence that retained foreign bodies were carefully ruled out, decisions about antibiotic use, decisions of primary versus delayed closure, rabies risk assessment, and other aspects of care.
  • In many locations, animal bites must be reported to local authorities.

Special Concerns

  • Pediatric patients
    • Previously bitten patients remain at risk if the dog, cat, or other animal that bit them continues to be aggressive or is located where another bite could occur.
    • Move the animal to another location.
