1, maintain sedation: found head injury, even if no coma should be fasted and limited water, lying still and relaxed, avoid emotional excitement, do not just move. 2, rapid hemostasis: should be immediately in place, the use of clothing or fabric for pressure bandaging to stop bleeding. Do not pull out the injury-causing object at the scene, so as not to cause haemorrhage. If there is brain tissue prolapse, the available bowl as a support and then add dressing bandage to ensure that the prolapsed brain tissue is not compressed. 3, the correct treatment of wounds: head injury, visible blood and water (cerebrospinal fluid) from the ear, nose out, then the patient should lie flat, the affected side down, so that blood or cerebrospinal fluid flow out smoothly. Do not block the external ear canal or nasal cavity with cloth or cotton to avoid its backflow and secondary intracranial infection. 4, to prevent accidental inhalation: most of the craniocerebral injuries have swallowing, cough reflex loss, throat and oral foreign bodies or secretions will block the respiratory tract and cause asphyxia. Therefore, the casualty should take a flat position, no pillow, head back to the side. 5, maintain respiratory ventilation: if the casualty has difficulty breathing and blue lips, apply both hands on both sides of the patient’s jaw angle to hold his jaw up and remove the oral foreign body to keep the respiratory tract unobstructed. 6, cardiopulmonary resuscitation: If the patient is confused, the aortic pulsation disappears, and the patient’s sternum and rib fracture can be ruled out, external chest cardiac compressions and artificial respiration should be performed immediately. Do not try to wake up the unconscious casualty by tapping or shaking. 7.Smooth and fast transportation: Once the awake patient has frequent, jet vomiting, severe headache, or is unconscious again after a short period of wakefulness, he or she should be quickly sent to a hospital in a condition to be resuscitated.
