The optimal recovery period for ischemic-hypoxic encephalopathy is between 3 and 6 months. Ischemic-hypoxic encephalopathy is a brain lesion caused by ischemia and hypoxia of the brain tissue due to various reasons. Impaired consciousness, mental disorders, and seizures may occur. Treatment should first remove the cause of the disease, correct the ischemic and hypoxic state, and give oxygen, artificial ventilation, and elevate blood pressure. After establishing effective circulatory and ventilatory function, treatment is directed at the damage of cerebral hypoxia. Drugs such as edaravone, cytidine diphosphate choline and ganglioside can be used for treatment so as to improve the symptoms. Treatments such as hyperbaric oxygen therapy and electrical nerve stimulation are also effective in improving the range of symptoms caused by ischemic-hypoxic encephalopathy. Once diagnosed with ischemic-hypoxic encephalopathy, one needs to actively cooperate with the doctor for treatment, and at the same time, family members should also do a good job in the daily care of the patient in order to alleviate the condition and improve the prognosis.
