Coma due to brain injury caused by car accident is mostly caused by severe head damage. First of all, CT of the head must be improved to clarify which location of the bleeding, and early measures related to control of intracranial pressure are recommended. This is because all neurosurgical disorders are basically caused by a series of consequences of increased intracranial pressure. The common modalities for reducing intracranial pressure include medication and surgery. When medication is ineffective, aggressive surgery is necessary because once the nerve cells are damaged they are irreversible and therefore surgery is required before irreversible necrosis of the nerve cells occurs. After surgery, if the patient is still recovering, there will usually be dysfunction, and the most important thing is to intervene through some wake-promoting means, such as hyperbaric oxygen, drugs, Chinese acupuncture and other therapies are all wake-promoting methods.
