The importance of the hand to people is self-evident, but due to the use of improper machines, car accidents and other causes of hand trauma is increasing. Timely and appropriate treatment at the scene, can create good prerequisites for hospital treatment, however, many people in the emergency treatment of hand trauma there are many misunderstandings: Misunderstanding one: blind binding trauma is generally accompanied by bleeding wounds, many people will be at the scene of their own with a bandage or a towel tied up, thinking that this can reduce the bleeding, in fact, this is a wrong point of view, the binding can only block superficial venous reflux, but can not block the arterial blood flow, but will make the wound more serious. Block arterial blood flow, but will make the wound more serious. Misunderstanding two: improper bandage after trauma bleeding, some patients often use toilet paper for local bandage, in fact, most of the toilet paper is not hygienic, and the paper material will be softened after seeing the blood, which increases the difficulty of trauma debridement and exacerbates the risk of infection. Misconception 3: local medication In the treatment of small wounds, common patients will sulfa powder and other powdered agents in the wound, that can play an anti-inflammatory role, in fact, sulfa powder mixed with blood will form a scab, in the short term to play a role in stopping the bleeding, but because the wound is not thoroughly cleaned up the internal, bacterial reproduction often occurs under the scabs of the accumulation of pus, affecting the healing of the wound, and even lead to deep infection. Misunderstanding four: localized without braking Some amputated limbs (fingers) incomplete severance of patients, in the transit did not brake the injury, which is very likely to cause further damage to blood vessels, nerves, and in severe cases, will lead to the loss of reimplantation conditions. Doctor’s tip: hand trauma should be clean fabric for localized pressure bandage, do not casually use drugs, amputation (finger) case to use splints to simply fix the affected limb (finger), and go to the hospital for treatment in a timely manner.
