Coma is a common and critical illness in emergency medicine. It is mainly caused by abnormal metabolism of the cerebral cortex and brainstem network structure that maintains normal conditions, causing the patient to lose consciousness, consciousness, etc. If the patient fails to receive timely and effective diagnosis and treatment after the onset of disease , Will threaten the lives of patients. However, because the patient was in a coma or impaired consciousness after admission, he was unable to describe his condition, medical history, etc., which increased the difficulty of clinical diagnosis. Coma is a common emergency and critical illness with a high fatality rate in the emergency department. It is more common in acute cardiovascular and cerebrovascular diseases, poisoning, and trauma. Because the patient presented with a severe disorder of consciousness, unable to provide relevant medical history and cooperate with diagnosis and treatment, and the etiology involved multi-disciplinary and multi-professional knowledge, it brought great difficulties to diagnosis, rescue and treatment. Therefore, how to quickly determine the cause of the disease in a short time and implement the correct rescue measures in the first time has become a great challenge for emergency medical staff. Medical research has shown that the diagnosis and treatment of coma patients must clarify the cause of the patient, understand the factors that cause the coma, and formulate targeted diagnosis and treatment measures. Therefore, clinically, it is necessary to strengthen the rapid diagnosis and timely examination of patients with coma in emergency medicine, understand the cause of the patient's coma, and adopt effective treatment methods, so as to stabilize the patient's vital signs and avoid further development of the disease.
