Immediate Treatment for a Finger Slammed in a Car Door

The immediate treatment for a finger slammed in a car door should include cooling the injury with clean running water for 5-20 minutes, assessing for potential fracture, controlling bleeding with direct pressure if needed, and covering with a clean dressing. 1

Initial Assessment and Management

• Assess the injury for severity, looking for obvious deformity, swelling, bruising, open wounds, or protruding bone that may indicate a fracture 1
• If there is active bleeding, apply direct pressure with a clean cloth or gauze to control bleeding 1
• If bleeding is severe and cannot be controlled with direct pressure, seek immediate medical attention 1

Cooling the Injury

• Immediately cool the injured finger with clean running water for 5-20 minutes to reduce pain, swelling, and depth of injury 1
• If running water is not available, use a clean cool or cold compress, but not freezing 1
• Do not apply ice directly to the injury as it can cause tissue ischemia (damage) 1, 2
• If using ice, wrap it in a thin towel or cloth to create a barrier between the ice and skin 1, 2

Pain Management

• Cooling the injury helps reduce pain and inflammation 3
• A 10-minute application of ice (properly wrapped) can effectively reduce pain and swelling 3
• Repeated short applications of cold (10 minutes) are more effective than continuous long applications 2

Fracture Assessment

• If there is obvious deformity, inability to move the finger, or severe pain with movement, a fracture should be suspected 1
• Do not attempt to straighten or realign a potentially fractured finger; leave it in the position found 1
• If the finger appears blue, purple, or pale, activate emergency medical services immediately as this indicates poor perfusion and a limb-threatening injury 1

Wound Care

• If the skin is broken, gently clean the wound with clean water with or without soap 1
• Remove any visible foreign material from the wound 1
• Cover the wound with a clean dressing to prevent infection 1
• For superficial wounds, an antibiotic ointment may be applied if there are no known allergies 1

When to Seek Medical Attention

Seek immediate medical attention if:

• The finger appears blue, purple, or pale 1
• There is severe bleeding that cannot be controlled 1
• There is obvious deformity suggesting fracture 1
• The nail is severely damaged or detached 1
• There is significant swelling, pain, or inability to move the finger 1
• The injury involves a deep wound or crushing injury 1

Follow-up Care

• Keep the injured finger elevated to reduce swelling 1
• Apply cold compresses intermittently (10 minutes on, 10 minutes off) for the first 24-48 hours 2, 3
• Monitor for signs of infection such as increasing pain, redness, warmth, or pus 1
• Avoid using the injured finger until healing has occurred or as directed by a healthcare provider 1
