Not long ago, British actress Natasha Richardson was injured in a fall while learning to ski at a Canadian ski resort. According to ski resort staff, she was not bleeding and showed no signs of trauma. Richardson later developed a severe headache and was taken to a local hospital and then transferred to a hospital in New York. Two days after her injury, she died of a trauma-induced brain hemorrhage. Experts analyzed that Richardson’s lack of timely examination and delayed treatment after her head injury was a major cause of her death. The head injury first called the emergency vehicle Peacetime, accidental death, traumatic brain injury in the first place. Natasha Richardson most likely had an epidural hematoma that didn’t start out serious, then the hematoma grew rapidly, compressing brain tissue and causing untimely resuscitation and death. The cranial brain is an extremely important organ in the human body, and a lack of oxygen for 5 minutes can cause brain death. Therefore, in the event of an accident, the first thing to do is to call for help from the emergency system. The rescuer should record the time of injury, the location of the injury and the body posture of the injured person. For patients who are conscious, the injured person can be allowed to narrate his or her condition and observe the activities of the injured person’s whole body. For the injured with neck and lumbar pain, special attention should be paid to lying down and ensuring that the head, neck and torso are in a horizontal position when carrying to avoid spinal cord injury. Comatose patients must lie flat and tilt the patient’s head back and to the side, and promptly clean up the secretions in the injured person’s mouth to prevent blockage of the respiratory tract caused by accidental inhalation. For scalp lacerations, a simple hemostatic dressing should be done. To measure the blood pressure, pulse and respiration of the injured person, observe whether the pupils of the injured person are equal in size and round, to provide the basis for further treatment by neurosurgeons. Craniocerebral injury treatment to race against time, when transferring attention must be closer to the hospital with neurosurgery conditions. Neurosurgeons should routinely give the injured person a cranial CT examination to determine the condition of the cranial injury, and immediately carry out the appropriate treatment and care. The more timely the treatment of cranial brain injury, the better the prognosis of the injured person. Some brain injuries must be operated The prognosis is determined by the degree of brain injury and the effect of treatment. Injuries less than 30 minutes after the injury coma, retrograde amnesia (recent memory loss, distant memory exists), dizziness and headache, such injuries are mild, can be moderate with analgesic drugs, bed rest 1 ~ 2 weeks can be cured. If the post-injury coma exceeds 30 minutes, the injured person may have intracranial hemorrhage, brain contusion and skull base fracture, etc. This is moderate, and the injured person needs to be hospitalized. If the injured person is unconscious for a long time, has unequal pupils, urinary incontinence, and has a large intracranial hematoma on CT scan, this is severe, and the hematoma should be removed surgically if needed. If the injured person has the following three conditions, surgical treatment is necessary to save life. One is an epidural hematoma, the other is a subdural hematoma, and the third is a large intracerebral contusion and intracerebral hematoma, progressive neurological deterioration associated with an intracerebral lesion, and refractory hypercranial pressure. A word of caution is to be on the alert for delayed hemorrhage. Delayed cerebral hemorrhage is usually high 3 days to 1 week after trauma. After the injury, the injured person should be closely observed to see whether he or she is conscious; whether the pupils are equal in size and round, whether the reflex to light is sensitive; whether the blood pressure, respiration and pulse are normal. If there is a severe headache, frequent vomiting, limb paralysis, speech disorders, impaired consciousness, etc., promptly seek medical attention. Protect your head in case of an accident Always wear a protective mask when skiing or riding a motorcycle. In case of body imbalance, first hold your head and face with both arms to reduce head injury. When going out for walks and activities, be sure to stay away from high-rise building complexes to prevent falling objects from height. Walk or stay less under steep mountain walls to prevent injuries from rolling rocks. Whether it is a car accident, a fall, a fall, or a blow, the brain injury caused by a human body landing on its back is more serious than the brain injury caused by a face to the ground. This is because the human body falls on its back, the hands will be conditioned to support, the force of the fall will slow down, the injury will be relatively light. Once a person falls on his back, it is difficult to protect the brain. Important nerve structures in the cranium, such as the brain stem are in the back of the brain, if the back of the brain directly on the ground brain damage will be more serious. If an accident occurs, the first thing to do is to hold the head and bend the body, which can play a cushioning role to protect the head. In the event of a natural disaster, you should take shelter in a relatively safe and solid place.
