Life, it is inevitable that the hand will be injured, hand trauma first aid to be fast, but also to know the correct way to deal with it, first of all, to stop bleeding, to prevent excessive blood loss, and if there is a broken finger, but also to save the broken finger, save it can be connected, hand trauma is very common, so we have to learn first aid measures, of course, none of us want to have an accident, but we have to prevent it before it happens, must protect themselves, hand trauma first aid to Master the scientific measures, scientific first aid, pay attention to the following points. Severe hand trauma so scientific first aid 1, hand trauma are emergency, patients need to be detailed account of the cause of injury, time, which helps to emergency treatment as soon as possible; 2, to help patients eliminate fear, and efforts to cooperate with the physician’s examination of the function of various systems of the hand (nerve, muscle, vascular, bone) and X-ray photos and other auxiliary examinations, in order to determine the treatment plan as soon as possible; 3, if the open hand trauma In case of open hand trauma, debridement surgery should be given as soon as possible within 6-8 hours after the injury (it can be extended to 12 hours in winter when the temperature is lower) to minimize the infection rate and preserve the fingers; 4. If there is skin defect and the trauma is exposed, after careful debridement and hemostasis, free implant or flap should be applied to cover it to repair the trauma, prevent infection and reduce edema and granulation process. Supplemented with early functional exercises, late scars and contractures can be prevented and disability can be reduced. 5, hand trauma combined with fractures, mostly accompanied by tendon and nerve, vascular injury, after the trauma first fixed fracture, can play a role in restoring the normal anatomical relationship of bones and its scaffolding fixed; 6, when the hand trauma first aid application of a large number of loose, clean dressing pressure bandage, hemostasis, elevation of the affected limb, such as hand trauma vascular injury after surgical repair, there is a more dramatic swelling, indicating poor venous reflux, must be closely observed, timely treatment; 7, hand trauma vascular injury. 7, hand trauma tendon injury, tendon repair should be as early as possible, such as the conditions allow suture tendon in the day of surgery or the next day can be fixed in elastic brace, protected flexion and extension functional exercise to prevent adhesions; 8, hand trauma nerve injury, the sooner the nerve repair recovery is better, must be in tension-free conditions, suture nerve under tension, can cause nerve ischemia, nerve scar proliferation, affecting recovery. If the defect is large, the nerve graft should be repaired as early as possible within 1-2 months after the injury. Hand trauma treatment of several misconceptions 1, not bandaged, let the wound dry naturally, in order to heal faster Wound healing requires a moist environment, if the finger is broken, under the premise of strict disinfection, it is best to cover the wound with gauze, which is conducive to rapid healing. 2, wound dressing tighter, not easy to infection dressing to leave a certain gap, otherwise it will reduce the wound contact with oxygen opportunities, so that the wound healing slower. In addition, the bandage is too tight will also hinder blood circulation. 3, bleeding, immediately stop bleeding with hemostatic powder At home to deal with wounds, try not to use hemostatic powder, otherwise it will stimulate the wound, but also cover the wound surface, to the doctor’s diagnosis and “secondary treatment” cause difficulties, need to spend time to remove the residue of hemostatic powder, the patient will also feel very painful. In fact, the first principle of hemostasis is to apply pressure on the wound until it does not bleed. 4, daily dressing change can be faster As long as you keep the wound clean, you do not need to change the dressing every day, you can change the dressing once every 3 days or so according to medical advice. If the dressing is changed every day, it will destroy the newly grown tissue and aggravate the formation of scar. 5, the healing wound grows a layer of yellow film, torn by hand In fact, this layer of film is the new granulation tissue, help wound healing, remove will be counterproductive.
