The danger period for cerebral hemorrhage coma is usually 2 to 3 weeks. Cerebral hemorrhage, a type of primary non-traumatic intracerebral hemorrhage in the brain parenchyma, is most commonly associated with hypertension combined with fine and small arteriosclerosis. Within 1~3 days after the occurrence of cerebral hemorrhage, the patient is often in a state of coma, when there is a possibility of delayed hemorrhage or rehemorrhage of brain tissue, which may damage the function of the brain, and in severe cases, respiratory and cardiac arrests may occur and lead to the patient’s death. Cerebral edema peaks 7 to 10 days after the onset of cerebral hemorrhage, at which time the patient’s vital signs must be actively monitored and the patient must follow the doctor’s instructions for active treatment. 2 to 3 weeks later, the cerebral edema gradually subsides, and the patient’s relative risk decreases. Cerebral hemorrhage coma will have a period of danger, in this stage need to carefully care for the patient and active treatment, in order to have a better recovery, and reduce the emergence of complications.
