Care Instructions for Mild Crush Injury

Initial Assessment and Management

The American Heart Association recommends assessing for signs of compartment syndrome using the "6 Ps": pain, paresthesia, paresis, pain with stretch, pink color, and pulselessness 2
The American College of Surgeons advises removing any tight-fitting dressings and avoiding limb elevation if compartment syndrome is suspected 2
Apply cold therapy (crushed or cubed ice with water) to reduce pain, swelling, and edema, limiting application to 20-minute intervals, as recommended by the American Academy of Orthopaedic Surgeons 2
Place a barrier, such as a thin towel, between the cold container and the skin to prevent tissue ischemia, according to the American Heart Association 1

The American Heart Association recommends thoroughly irrigating superficial wounds and abrasions with a large volume of warm or room temperature potable water until there is no foreign matter in the wound 1
Cover the wound with an antibiotic ointment or cream and a clean occlusive dressing to improve healing and reduce infection risk, as advised by the American Heart Association 1
Leave blisters intact and loosely cover them with a sterile dressing to improve healing and reduce pain, according to the American Heart Association 1

For mild crush injuries without systemic symptoms, oral hydration is usually sufficient, as stated by the National Kidney Foundation 3
For more significant crush injuries, intravenous fluid resuscitation may be necessary, with an initial rate of 1000 ml/h of 0.9% saline to be tapered by at least 50% after 2 hours, according to the National Kidney Foundation and the American College of Surgeons 3, 2
Avoid potassium-containing balanced salt fluids such as Lactated Ringer's solution, as potassium levels may increase markedly even with intact renal function, as warned by the National Kidney Foundation and the American College of Surgeons 3, 2
Avoid starch-based fluids as they are associated with increased rates of acute kidney injury and bleeding, according to the National Kidney Foundation and the American College of Surgeons 3, 2

Watch for dark urine (indicating myoglobinuria), decreased urine output, and signs of kidney dysfunction, as recommended by the National Kidney Foundation 3
Be alert for signs of infection: increasing pain, redness, warmth, swelling, or purulent drainage, according to the American Heart Association 1

Seek medical attention for burns with blistering or broken skin, as advised by the American Heart Association 1
Seek medical attention for difficulty breathing, according to the American Heart Association 1
Seek medical attention for injuries to the face, neck, hands, or genitals, as recommended by the American Heart Association 1
Seek medical attention for injuries covering a large surface area, according to the American Heart Association 1
Seek medical attention for signs of compartment syndrome: severe pain, especially with passive stretching of the muscles, paresthesia, pallor, or pulselessness, as advised by the American College of Surgeons 2
Seek medical attention for dark urine or decreased urine output, as recommended by the National Kidney Foundation 3
Seek medical attention for signs of infection: increasing pain, redness, warmth, swelling, or purulent drainage, according to the American Heart Association 1

Topical haemostatic agents can be used in combination with other measures for venous or moderate arterial bleeding associated with parenchymal injuries, as stated by the Society of Critical Care Medicine 4
Hyperbaric oxygen therapy may enhance wound healing in patients with crush injuries, but evidence is limited, according to the American Academy of Orthopaedic Surgeons 5

Early and adequate fluid resuscitation is key to preventing crush syndrome and acute kidney injury in more severe crush injuries, as recommended by the National Kidney Foundation and the American College of Surgeons 3, 2
Monitoring electrolytes, acid-base status, and kidney function can help detect early signs of complications, according to the National Kidney Foundation 3
Failure to recognize crush injury early can miss the narrow time window when intensive fluid resuscitation may prevent acute kidney injury, as warned by the American College of Surgeons 2
