Initial Care for Minor Crush Injury to the Hand

Immediate Assessment and Management

The American Heart Association recommends thorough irrigation of the wound with running tap water or sterile saline until all debris is removed, then apply an occlusive dressing to promote healing 1
Assess for signs of compartment syndrome using the "6 Ps": pain, paresthesia, paresis, pain with stretch, pink color, and pulselessness 2
Remove any tight-fitting dressings and avoid limb elevation if compartment syndrome is suspected 2
Apply cold therapy (ice with water) for 20-minute intervals with a thin towel barrier between ice and skin to reduce pain and swelling 2

Irrigation with tap water is as effective as sterile saline for cleaning wounds and preventing infection 1
Avoid using antiseptic agents such as povidone-iodine for wound irrigation as they show no additional benefit 1
Cover the cleaned wound with an occlusive dressing (film, petrolatum, hydrogel, or cellulose/collagen) which promotes better healing than dry dressings 1
Leave blisters intact and cover them loosely with a sterile dressing 2

Monitor for signs of infection: increasing redness, swelling, foul-smelling drainage, increased pain, or fever 1
Watch for dark urine (indicating myoglobinuria) or decreased urine output which may suggest more severe crush injury 2
Be alert for worsening pain disproportionate to the injury, which may indicate periosteal penetration or compartment syndrome 2, 3

Seek medical attention for signs of compartment syndrome (severe pain, especially with passive stretching, paresthesia, pallor, or pulselessness) 2
Seek medical attention for wounds caused by animal or human bites or contaminated with saliva 1
Seek medical attention for injuries to the hand that show progressive infection despite proper care 3
Seek medical attention for pain disproportionate to the severity of injury, especially near bones or joints 3

Hand wounds often require more careful attention than wounds to fleshier body parts due to the complex anatomy and risk of functional impairment 3
For suspected foreign bodies in the hand when radiographs are negative, ultrasound or CT may be appropriate for further evaluation 4, 5
Ensure tetanus prophylaxis is current; if outdated or unknown, administer tetanus toxoid 3
