Most patients in coma after cerebral hemorrhage usually wake up within one month, and if they do not wake up within three months, the prognosis of the patient is poor. The length of coma after cerebral hemorrhage is inconsistent, depending on the patient’s actual condition, and is related to the site of bleeding, the amount of bleeding, the presence of serious complications, such as hydrocephalus, elevated intracranial pressure, pneumonia, pulmonary embolism, etc., and also closely related to the degree of coma. Early and active treatment and rehabilitation measures such as acupuncture, massage, limb massage and passive limb movement after stabilization can promote patients’ awakening, prevent limb contracture and promote functional recovery. Therefore, how long a patient is in a coma and whether he or she can wake up depends on the severity of the patient’s actual condition. If he or she cannot wake up within a year, the patient may be in a coma for a long time and the chance of waking up is extremely small.
