Human and Other Mammalian Bite Injuries of the Hand: Evaluation and Management

Pdf Summary

Bite injuries to the hand are common and can lead to serious infections if not treated properly. The hand is particularly vulnerable to infections from bite wounds due to its anatomy, bite mechanics, and the bacteria found in saliva. Both human and animal bites can result in polymicrobial bacterial infections with a mix of aerobic and anaerobic organisms. Dog bites commonly lead to infections from Pasteurella species, while human bites are often infected with Eikenella. There is also a risk of transmitting diseases such as rabies, HIV, and hepatitis through bites. Proper management of bite wounds includes recognizing the injury, cleaning the wound, evaluating for any damage to structures, and taking steps to prevent infection. Structural repair may be necessary depending on the severity and contamination of the wound. Wound infections typically require debridement, antibiotics, and delayed repair or reconstruction. The incidence of bite injuries is difficult to calculate, but it is estimated that millions of people are bitten by dogs each year. The cost associated with managing dog and cat bite wounds is significant, and the true incidence is likely underestimated because minor injuries are often self-treated without medical attention. In conclusion, bite injuries to the hand require prompt recognition and appropriate management to prevent complications and morbidity.
