Children are lively, lovely, active, treat all kinds of new things will be curious, especially after the beginning of learning to walk, it is inevitable to bump, all kinds of trauma may lead to children fracture and other injuries to children. Once the child trauma, there is crying, pain in the affected limb, activity is limited, unwilling to move, swelling and deformity of the upper limb, the child is unwilling to take things, the lower limb walking difficulties and other manifestations. Once a child has a limb injury, how should the aggravators deal with it? If there is a fracture, you should first do the fixation, you should do a simple fixation and then carry or move the limb. 1, upper limb fracture, can first use cardboard, thin wooden board or bamboo board simple fixed, and then use cloth strip with simple binding, really can’t find splints, can be tied together with the body, but don’t tie too tight, to avoid limb ischemic necrosis. 2, lower limb fracture, can make a splint (cardboard, thin board or bamboo board) fixed, and then tied with cloth strips, really can not find a splint, you can also tie the two legs together to fix the action to be gentle, to avoid the fracture end of the dislocation, damage to the important blood vessels, nerves and surrounding tissues. If you fall from a high place and have a back injury, do not move the child as much as possible, let the child lie flat in the same place, immediately call 120 for help, and at the same time, look for a stretcher, if there is no stretcher, you can use a wooden board or a door plate instead of a stretcher, and let the ambulance take the child to the hospital for further checkups and treatments. The way a spine fracture victim is transported from the scene of the injury to the hospital is critical. Carrying the fractured spine with one person lifting the head and one person lifting the feet or cradling the person in an embrace is very dangerous because these methods increase the curvature of the spine, which may push the broken bone fragments backward into the spinal canal and aggravate the spinal cord injury. The correct method is to use a stretcher, board or door to transport. First, make the casualty’s lower limbs straight, the stretcher is placed on the side of the casualty, and the handler will support the casualty to the stretcher with his hands, or use the rolling method, so that the casualty will remain flat and straight, and roll to the stretcher as a whole. Regardless of the method of transportation, care should be taken to maintain the stability of the injured person’s neck so as not to aggravate the cervical spinal cord injury. After initial immobilization, try to keep the child as quiet as possible, do not move around, lie flat on a hard, level surface, and reduce movement, bumps, and jarring to avoid re-displacement of the fracture. Once a child has a fracture, you should immediately call the emergency number of the hospital or send your child to the hospital, and you should not treat the fracture privately at home or apply herbs or traditional Chinese medicines externally, so as not to delay the condition. Children should be educated more to establish safety awareness. When parents take their children out, they must pay attention to observe the surrounding environment to see if it is safe, and conduct a safety assessment before letting their children play to avoid injury.
