Craniocerebral injury is a common brain injury in life, heavy craniocerebral injury patients with complex injuries, critical condition, the death rate of 30% to 50%, and often secondary injury is heavier than primary brain injury, the earlier to remove the factors that cause secondary brain injury, the lighter the patient’s secondary injury, the higher the survival rate, so an important indicator of the effectiveness of pre-hospital emergency is the response time. Patients with severe craniocerebral injury present the first death peak at lh after injury, and the number of deaths at this moment accounts for 50% of trauma deaths, which is also known as “golden 1h” in clinical death, and patients must be rescued at this stage. Therefore, pre-hospital emergency can resuscitate the heart, lung and brain function of heavy craniocerebral injury patients much earlier, and win valuable time for further treatment in hospital. Pre-hospital emergency creates favorable conditions for the follow-up of patients with heavy craniocerebral injury, which can significantly improve the prognosis of patients. The application of timely and effective pre-hospital emergency measures can start the basic life support and anti-shock treatment as early as possible, avoiding the occurrence of hypotension, hypotension and hypoperfusion pressure, thus reducing the difficult to control intracranial hypertension and acute cerebral bulge; the correct and timely transfer method avoids and delays the occurrence of brain sores, controlling the deterioration of the plant. The correct and timely transport method avoids and delays the occurrence of brain sores, controls the deterioration of the plant, and creates favorable conditions for subsequent treatment, thus significantly improving the post-top of patients with heavy cranial irritation injury. Some patients were sent directly to the hospital by their families within the injury shield, and due to the lack of awareness of the family members, the transport was too bumpy and did not pay attention to head protection, resulting in increased intracranial hemorrhage and even life-threatening brain herniation; or due to posterior tongue drop, sputum was not cleared in time to aggravate the respiratory blockage of hypoxia; coupled with the lack of timely medication, prolonged cerebral hypoxia, cerebral edema, resulting in patients with severe disability, vegetative state, death The prognosis of patients with severe disability, vegetative state and death is significantly higher than that of patients with pre-hospital emergency care. Therefore, timely and effective pre-hospital emergency care wins time for the rescue of patients with heavy craniocerebral injury, which can significantly improve the survival rate and survival quality, reduce the occurrence of death and disability, and is of great significance to improve the prognosis of patients.
