Dog and Cat Bites: Rapid Evidence Review

Area of Science:

• Emergency Medicine
• Public Health
• Wound Care

Background:

• Animal bites represent a substantial global health burden, with dog bites alone causing numerous emergency visits and high medical costs annually in the US.
• Most animal bites, particularly in children, involve familiar animals and can result in crush injuries or deep punctures.
• Bite wound characteristics vary by animal and patient age, affecting injury patterns and management strategies.

Purpose of the Study:

• To outline the epidemiology and clinical presentation of animal bites.
• To provide evidence-based guidelines for the initial management of bite wounds.
• To discuss considerations for infection prophylaxis, tetanus vaccination, and rabies postexposure prophylaxis.

Main Methods:

• Review of current literature and clinical guidelines on animal bite management.
• Emphasis on thorough wound examination, cleaning, irrigation, and debridement.
• Discussion of prophylactic antibiotic use, imaging, and wound closure techniques.

Main Results:

• Dog bites often cause crush injuries, while cat bites tend to be puncture wounds, with specific anatomical distributions based on age.
• Proper wound care involves examination, cleaning, irrigation, and removal of foreign bodies and devitalized tissue.
• Antibiotic prophylaxis (e.g., amoxicillin/clavulanate) is recommended for at-risk bites, and tetanus/rabies status must be assessed.

Conclusions:

• Effective management of animal bites requires prompt and thorough wound care, appropriate prophylaxis, and assessment for potential complications.
• While imaging is usually not needed, it is considered for suspected foreign bodies, underlying damage, infection, or extensive injuries.
• Primary closure is an option for low-risk wounds, and tetanus and rabies prophylaxis decisions are patient-specific.
