Craniocerebral trauma has become the fourth cause of death after heart disease, malignant tumor and cerebrovascular disease, mostly caused by falling injury, brawl or traffic accident, and ranks second in trauma after limb injury in terms of incidence. Craniocerebral trauma is an injury caused by external violence directly or indirectly acting on the head, and is divided into open and closed injuries according to whether the brain tissue is connected to the outside world after the injury. There are three common types of head trauma: scalp abrasions, lacerations, and blood clots. Scalp abrasion: only the injury of the superficial part of the scalp, there is a small amount of bleeding or blood oozing from the injury. Treatment will first cut the wound and its surrounding hair, with soapy water, then physiological saline (can be prepared by themselves, to 1000 ml of water with salt 9 grams of boiling will become) wash, wipe dry, coated with red or purple potion, a boat without bandages, if the trauma mud, more dirt, quickly to the hospital to deal with as appropriate. Scalp laceration: due to the rich vascularity of the scalp, sometimes bleeding comes very hard, it is not easy to find the bleeding point. Can pay attention to the most blood in the place separate the hair, look carefully, use your fingers to compress the skin on one side of the bleeding point or press the skin around the wound, can stop the bleeding, also can be used to compress the wound with a clean cloth to stop the bleeding, and promptly bandaged and sent to the hospital. Scalp blood clots: no damage to the epidermis at the trauma, only a local hematoma or hard mass. At this time, the early local application of cooking oil or local heavy pressure bandage should be used to prevent the expansion of the mass. Do not use bruising medicine and wine to apply and press and push the local area. If a reddish, soft to touch and watery feeling mass has been formed, that is, after 24 hours of hematoma, hot compress can be used to promote absorption, and for large hematoma not easily absorbed, it is forbidden to casually puncture and bleed with a needle, and should be handled by a physician. Such as head trauma coma, some in the injury that there is a loss of consciousness, confusion, there are two cases: one is a very short coma time, in a few minutes to 30 minutes awake more concussion; some no coma but the memory of the events before the injury loss, medically known as retrograde amnesia, such casualties should be sent to the hospital as soon as possible for treatment. Before sending the patient to the hospital, let the patient lie down, remove the pillow, head turned to the side, to prevent food inhalation when vomiting and asphyxiation, not to pinch or shake the head to wake up the patient, which will aggravate the degree of brain damage and bleeding.
