Transient coma causes: First, it may be a TIA attack. TIA is a transient ischemic attack, which can be caused by hypoglycemia or infectious shock, cardiogenic coma, emotional overexcitement, sadness, etc. The disease is caused by a transient lack of blood supply to the carotid and vertebrobasilar systems. Patients become unconscious, unsteady on their feet, and in severe cases, monoplegia and hemiplegia. The coma is short with or without sequelae, and the cause is cerebral atherosclerosis and microembolism, which can be treated with aspirin enteric tablets. Second, hypoglycemia, the disease often coexists with malnutrition, but also diabetic patients taking too much hypoglycemic drugs, or eating untimely related to the patient’s blood glucose test value of 1.3 mol/L or less. The appearance of hypoglycemic coma, which lasts for a short time can regain consciousness. Third, cardiogenic shock, due to various cardiac causes, such as A – S syndrome leads to a decrease in cardiac output function and cardiac blood excretion, which affects the normal function of the organism and leads to transient coma. Fourth, other causes, such as hepatic encephalopathy, pulmonary encephalopathy, etc., may also appear similar symptoms.
