Broken fingers can't be frozen, and they can't survive after freezing. Send the severed finger directly to the hospital (if it is possible to replant it), and the consequences of finding the wrong hospital are very serious. At the same time of first aid, if the damaged parts are still in the machine during first aid, it is not necessary to break the limb or invert the machine to avoid increasing the damage.
When they learned that the 3D finger reconstruction technology in our hospital can be used to reconstruct the toes, and the appearance and function can be restored to the original appearance of the fingers, they came here anxiously. . . When giving first aid at the scene, if the severed finger is still in the machine, it is not necessary to turn the severed limb or the machine upside down to avoid increasing injury. Stop the machine immediately and try to disassemble the machine and take out the broken finger.
Take the hand as an example. Stop the bleeding with a tourniquet immediately after the hand falls, then wrap the injured hand with a towel, or take off your clothes and wrap it in two layers. Put it in a double plastic bag, cover one of the two plastic bags, wrap it and seal it, and then find another plastic bag. According to the nature of finger injury, it can be divided into three types: cutting injury, rolling injury and tearing injury. Symptoms are obvious after finger amputation, and it is easy to diagnose. First aid methods include hemostasis, dressing, preservation of severed fingers and rapid transportation.
After amputation of limbs and fingers, although the blood supply is lost, it still has vitality in a short time and will degenerate and rot with time. Therefore, it is possible to replant the severed finger if we can master the correct preservation method. But there is still a small connection between skin and tissue, which may include small blood vessels and nerves. Handle it carefully. Reset the severed finger and properly bandage it to prevent blood vessels from twisting or stretching.
