sometimes to determine extent of injuries.
APPROPRIATE HEALTH CARE

- Doctor's treatment.
- Wound cleaning.
- Surgical closure if needed.
- Wound will usually be left open to heal to lessen risk of infection.
- Splint hand if it is injured.
- Human bite wounds on the hands should not be primarily closed due to the high risk of
infection.
POSSIBLE COMPLICATIONS--Complications from bites can included infection,
extensive soft tissue injuries with scarring, hemorrhage, rabies, and sometimes death.
PROBABLE OUTCOME--Wounds should steadily improve and close over by 7-10 days.
How To Treat
