Steps for first aid treatment of a crush injury are:
Stop bleeding by applying direct pressure.
Cover the area with a wet cloth or bandage, then raise the area above the level of the heart, if possible.
If there is suspicion of a head, neck or spinal injury, immobilize those areas if possible and then limit movement to only the crushed area.
Call your local emergency number (such as 911) or local hospital for further advice.
Crush injuries usually require emergency department evaluation. Surgery may be needed to correct and treat the problem fully.
