With the development of modern science and technology and the development of transportation, the morbidity of trauma is increasing, especially craniocerebral trauma has become the primary cause of death in adolescents, and its morbidity and mortality rate accounts for 85% of the whole trauma patients. Therefore, the treatment of heavy craniocerebral injury has become a difficult problem that neurosurgeons must face. In order to improve the level of craniocerebral injury treatment and reduce the death rate, time is a very important factor in the rescue and treatment of craniocerebral trauma. The earlier the treatment, the higher the survival rate and quality of survival of the injured, the lower the mortality and disability rate. First, the scene disposal The brain is an extremely important organ of the human body, ischemia and hypoxia for 5 minutes can cause brain death. On-site rescuers should record the time of injury, the location and posture of the injury. For patients who are conscious, you can let the injured person describe their condition and observe the activities of the injured person’s whole body. For neck and lumbar pain, special attention should be paid to making the injured person lie flat, and attention should be paid to keeping the injured person’s head, neck and torso in a horizontal position when handling, so as not to cause spinal cord injury. Patients who are unconscious must lie flat and have their heads tilted back and to the side, and promptly clean the secretions in the mouth of the injured person to prevent blockage of the respiratory tract caused by accidental inhalation. When there is active bleeding must be dealt with on the spot, the conditions can be selected gauze, bandages, etc. to dressing to stop bleeding, no such materials can be applied in situ clothes, bed sheets, etc. Second, the nearest medical treatment craniocerebral injury treatment to race against time, when the transfer of attention must be to the nearest hospital with CT examination and neurosurgery conditions. Emergency surgeons routinely perform cranial CT examinations to determine the condition of the cranial injury. The more timely the treatment of cranial injuries, the better the prognosis for the injured person. The emergency surgeon should also check the whole body of the injured person, pay attention to other parts of the injury, prevent the unconscious patient from being missed, and treat the patient in a comprehensive manner. Common life-threatening are multiple rib fractures, hemopneumothorax, cervical fractures, pelvic fractures, limb fractures, liver rupture, spleen rupture, kidney rupture, intestinal perforation, etc. Third, craniocerebral injury typing diagnosis and treatment clinical application of typing can only make diagnosis and typing of craniocerebral injury patients for the injury site and pathological type, but can not make a judgment on the severity of the patient’s condition. China in 1960 for the first time developed the “acute closed craniocerebral injury typing” standard, according to the coma time, positive signs and vital signs will be divided into light, medium and heavy 3 types, after two revisions have been more perfect, has become a recognized domestic standards. Level I: called craniocerebral injury level I, that is, mild craniocerebral injury (called concussion in the past, is not used). Referring to the injury at the time of coma, coma time within 30 minutes, and cranial spiral CT multiple scans are no abnormal findings. Clinically, according to its performance, it is artificially divided into 3 levels: light concussion; medium concussion; heavy concussion. Generally, light concussions have no sequelae, while medium and heavy concussions may have different degrees of sequelae according to individual differences (i.e., post-cranial injury syndrome), such as headache, dizziness, nausea, vomiting, memory loss, and even mental decline. The above manifestations can be continuous live intermittent episodes, and long-term can not be completely relieved. General craniocerebral injury level I that should be treated systematically to prevent sequelae. Level II: moderate craniocerebral injury. Referring to the time there is coma, coma time greater than 30 minutes, and less than 1 hour, cranial spiral CT examination suggests that there is hemorrhage or edema area. This level must be hospitalized for formal treatment, because the bleeding may change at any time, resulting in the transformation to severe cranial brain injury, or even death. Depending on the situation and decide whether to surgery, general conventional drug treatment, closely observe changes in the condition. Grade 3: severe craniocerebral injury. This refers to coma time greater than 1 hour or even continuous coma, with disorders of vital signs, cranial spiral CT examination suggests: there is hemorrhage or edema or brainstem area low density images (brainstem injury). The mortality rate in this group of patients is high and can be 50% or more if the brainstem is injured. Treatment is the same as moderate. Fourth, be alert to delayed hemorrhage Usually after craniocerebral trauma, the CT examination of the injured person at that time did not reveal abnormalities such as brain hemorrhage, brain contusion, fracture, etc. However, beware of delayed intracranial hemorrhage. Delayed cerebral hemorrhage is usually high 3 to 7 days after trauma. It is important to closely observe the condition of the injured person, mainly to see whether the consciousness is clear, whether the pupils are equal in size and round, whether the reflex to light is sensitive, and whether the blood pressure, respiration and pulse are normal. If the following conditions occur, the patient should be sent to the emergency surgery in time: severe headache, frequent vomiting, limb paralysis, speech impairment, and impaired consciousness. V. Pay attention to three groups of people Intoxicated people because of unconsciousness, poor instinctive organism protection response after trauma, and because they cannot cooperate with the examination, thus it is recommended to do the corresponding examination as early as possible for this type of injury. Elderly people are more prone to intracranial hemorrhage after craniocerebral trauma because of brain atrophy, while there are many elderly people who take anti-platelet drugs for a long time to prevent heart and brain infarction, and the chance of late issuance of blood is also higher. Infants and young children have incomplete brain development and at the same time cannot speak about the injury. The above three special categories of patients should be noted.
