A 30-year-old man sustains a puncture from a high-pressure paint gun to the right index finger with a small skin disruption and paint under the dermis. What is the most appropriate management?

• A. Transfer to the emergency department for immediate orthopedic evaluation
• B. Apply a simple dressing and discharge
• C. Splint and observe
• D. Start systemic antibiotics and discharge

Answer: (A)

High-pressure injection injuries to a finger are surgical emergencies because the surface wound often looks minor while deep structures—tendons, joints, nerves, and vessels—can be severely damaged. The force pushes paint and solvent under the skin, causing chemical injury, tissue edema, and compartment-like pressure that can rapidly worsen. This combination makes early surgical assessment crucial to prevent lasting disability, infection, or even amputation.

Therefore, the best course is to transfer the patient to the emergency department for urgent hand/orthopedic evaluation, often with the consideration of prompt surgical debridement or decompression if indicated. Delaying for simple dressing, observation, or splinting can miss evolving deep injury and lead to poorer outcomes. In the meantime, immobilize the finger, cover with a clean dressing, and ensure tetanus prophylaxis as appropriate.
