Traumatic bleeding is mechanical factors cause human tissue or organ damage. According to location, injuries, injury tissue and inducing factors and skin integrity for analysis. Trauma can cause systemic reactions, local pain, swelling, tenderness in injured area; when the fracture-dislocation malformations and functional disorders. Severe trauma may also have a fatal haemorrhage, shock, suffocation and unconsciousness. First aid should first combat shock, airway, and dressing on the wound to stop bleeding, and limb is fixed, the casualty safely, smoothly and quickly transferred to the hospital for further treatment, debridement of open wounds in time line. For safety education and injury prevention is to adopt security measures.
When the tourniquet, first in parts with a towel or bandages over wounds wound on the skin, and rubber hoses elongate, wrapped tightly in a towel or bandaged limbs, then tie a knot. Tourniquet should not be wrapped too loose or too tight, with blood no longer flows for the degree. Injury of upper limbs attached to the upper arm, lower limb injury around the thighs, will reach the Haemostatic purposes. Tie the tourniquet's time, in principle not more than an hour, if you need a longer time to tie a tourniquet, you should loosen tourniquet for half a minute every half an hour or so. At the time of release of the tourniquet should be wound, so as to avoid bleeding. External traumatic hemorrhage of blood vessels with thumb over (proximal), causes the blood vessels to be shut, disrupting blood flow. Much the same method of bleeding and capillary bleeding, but with a little pressure with bandaged; not too large venous bleeding, General Haemostatic purposes can be achieved using the methods above. Bleeding is generally ferocious, bright red color, Jet-like flow with the heart beating. Arterial bleeding can lead to death within a few minutes, be rushed to the hospital for treatment.
