With the continuous development of modern society, road traffic is increasingly developed, the number of motor vehicles is rising year by year, traffic accidents have become a major causative factor of cranio-cerebral injury. Once a craniocerebral injury occurs in a traffic accident, the condition is often serious, and surgery generally addresses the compression of brain tissue by intracranial hematoma, which is the reason why surgery is necessary after a craniocerebral injury. But what about patients who are post-operative or do not require surgery? Of course, patients with milder conditions are transferred directly to a general ward or discharged from the hospital. However, patients with more complex conditions and who are unable to wake up in the near future are usually admitted to the ICU or neurosurgical care unit. And how should these patients with severe nerve damage be treated for their damaged nerves? At present, there is no specific drug or treatment that can cure the damaged nerve quickly and effectively, but the effect of hyperbaric oxygen with drug treatment and early rehabilitation is generally recognized for this kind of patients. However, such patients live in other departments, drugs and rehabilitation can generally be satisfied, but whether hyperbaric oxygen can be done is often ignored, because these patients are heavier, the department where they are afraid of problems; and then a hospital’s hyperbaric oxygen department does not have its own monitoring ward, the grasp of the disease is not in place, often delaying the patient’s treatment time, while the role of hyperbaric oxygen for damaged nerve repair is undoubted, especially early stage! The purpose of our hyperbaric oxygen monitoring ward is to admit patients with early and severe disease to give them the maximum treatment, in order to seek a better prognosis for the patients and reduce the disability rate.
