how many days can't a deep coma last longer?

clinically, deep coma is usually caused by brain lesions that cause the patient to lose consciousness. this situation is often caused by brain trauma or cerebral hemorrhage. long-term cerebral ischemia and hypoxia, and the patient is in a deep coma, will have a serious impact on brain cells. generally, it cannot exceed two weeks at most. if it exceeds two weeks, irreversible lesions may occur, including the destruction of brain cells. die.

it is also very critical to care for patients in deep coma. the nursing staff around the patient must closely observe the changes in the patient's condition, including the coma process, degree of coma, body temperature, pulse, and neurological symptoms and signs. at the same time, attention should also be paid to observing whether there are hemiplegia, neck stiffness and pupil changes. the patient should be in an absolutely supine position in bed and turn his head to one side to prevent vomitus from accidentally entering the trachea. turning over should be done with a low amplitude and the operation should be gentle, so that the muscles are in a relaxed state to avoid contracture of limb muscle joints and facilitate the recovery of functions. in addition, attention should also be paid to patient nutrition and water and electrolyte balance.
