The best recovery period of severe craniocerebral injury is within 6 months, which is divided into acute stage and recovery stage, timely and effective treatment has significant effect on the prognosis of patients. 1. Acute stage: 2 weeks after the injury, the treatment of patients in the acute stage of craniocerebral injury firstly guarantees the smoothness of the airway, and at the same time, oxygen supply is carried out to avoid the shock of patients in shock. If brain herniation occurs, emergency surgery should be performed to remove intracranial hematoma and save lives. For patients with acute stage heavy craniocerebral injury, including coma, vomiting and other symptoms should be prioritized to keep the airway open, and if necessary, tracheal intubation should be given in time to control the airway and ensure the supply of oxygen, so as to avoid hypoxia and aggravate brain damage after brain injury. 2. Recovery period, from two weeks to six months after injury. During this period, after the fluctuation and instability of the acute period, the vital signs of the patients are stabilized, and then through active rehabilitation therapy, the degree of craniocerebral injury can be effectively reduced, the sequelae can be reduced, and the recovery can be promoted, and psychological intervention can be given, which can help the prognosis of the patients. Severe craniocerebral injury requires urgent medical treatment, active cooperation with doctors and standardized treatment to promote recovery.
