Deep Dog Bite to the Right Arm: Neurovascular Assessment, Consultation, and Infection Prevention
A 34-year-old right-hand-dominant adult presents to the emergency department approximately 2 hours after being attacked by an unfamiliar dog. Bleeding was controlled with a pressure dressing before arrival. The dog cannot immediately be located for verification of vaccination status. On arrival, the patient is alert and hemodynamically stable. The right arm has several deep punctures and lacerations with gross contamination and swelling. During the initial examination, the clinician obtains the displayed external wound photograph; it is not an operative image or diagnostic scan. Before analgesia, the patient reports numbness along the dorsoradial forearm and difficulty extending the wrist and fingers. Radial and ulnar pulses are palpable, capillary refill is normal, and the hand is warm.
