Animal Bite

Adult HouseCalls Online

DEFINITION

  • Bite or claw wound from a pet, farm or wild animal

General Information

  • Animal bites usually need to be seen by a physician because all bites are contaminated with saliva and are prone to wound infection.
  • Bites from Rabies-Prone Wild Animals: Rabies is a fatal disease.  Bites or scratches from a bat, skunk, raccoon, fox, coyote, or large wild animal are especially dangerous. These animals can transmit rabies even if they have no symptoms. Bats have transmitted rabies without a detectable bite mark.
  • Small Wild Animal Bites: Small animals such as mice, rats, moles, gophers, chipmunks, and rabbits fortunately are considered to be free of rabies. Squirrels may rarely carry rabies, but have not transmitted it to humans. These bites can sometimes get infected.
  • Large Pet Animal Bites: Most pet bites are from dogs or cats. In most metro areas in theU.S. and Canada, the main risk from pet bites is serious wound infection, not rabies. Cat bites become infected more often than dog bites. Claw wounds from cats are treated the same as bite wounds, since the claws may be contaminated with saliva. Bites from pet pigs or primates also have a high rate of wound infection. Bites on the hands or feet have a higher risk of infection than bites to other parts of the body.
  • Small Indoor Pet Animal Bites: Small indoor pets (gerbils, hamsters, guinea pigs, white mice, rats, etc.) carry no risk for rabies. Puncture wounds from these small animals don't need to be seen. There is only a small risk for developing a wound infection.

FIRST AID Advice for Bleeding: Apply direct pressure to the entire wound with a clean cloth.

FIRST AID Advice for all Bites and Scratches: Wash all bite wounds and scratches with soap and warm water.

HOME CARE ADVICE FOR MINOR ANIMAL BITE

  1. Bleeding: For any bleeding, apply continuous pressure for 10 minutes.
  2. Cleansing: Wash all wounds immediately with soap and water for 5 minutes. Scrub the wound enough to make it re-bleed a little. Also, flush vigorously under a faucet for a few minutes (Reason: can prevent many wound infections).
  3. Antibiotic Ointment: Apply an antibiotic ointment (e.g. Neosporin, Bacitracin) to the bite 3 times a day for three days.
  4. Pain Medication:
    • For pain relief, take acetaminophen or ibuprofen
    • Acetaminophen (e.g., Tylenol): The dose is 650 mg by mouth every 4 hours or 1000 mg by mouth every 6 hours. Maximum dose per day = 4000 mg.
    • Ibuprofen (e.g., Motrin, Advil): The dose is 400 mg by mouth every 6 hours or 600 mg by mouth every 8 hours.
    • People who are over 65 Years of age: Acetaminophen is generally considered safer than ibuprofen. Acetaminophen dosing interval should be increased to every 8 hours because of reduced liver metabolism. Maximum dose per day = 3000 mg.
    • CAUTION: Do not take ibuprofen if you have stomach problems, kidney disease, are pregnant, or have been told by your doctor to avoid  this type of anti-inflammatory drug. Do not take ibuprofen for more than 7 days without consulting your doctor.
    • CAUTION: Do not take acetaminophen if you have liver disease.
    • Read the package instructions thoroughly on all medications that you take.
  5. Expected Course: Most scratches, scrapes and other minor bites heal up fine in 3 to 5 days.
  6. Call Your Doctor If:
    • Wound begins to look infected (redness, swelling, warmth, tender to touch, or red streaks)
    • You become worse

And remember, contact your doctor if you develop any of the "Call Your Doctor" symptoms.
