The time to get out of bed after craniotomy must be treated specifically according to the specific condition at that time. If the patient is clear after craniotomy, has the will to express himself, and the limbs are flexible, he can get out of bed basically after 3 days. Usually, on the first day, the patient is lying down, and on the second day, the patient can gradually shake the bed up to an angle of 60 degrees and gradually resume the normal physiological behavior, and on the third day, the patient can basically stand properly at the bedside, and if there is no abnormal reaction, the patient can go down to the ground and move freely. In some cases, the condition is relatively serious after craniotomy, with coma and limb hemiparesis, so the time to get out of bed is relatively long, some even need 1-2 months to slowly get down to the ground, and some become vegetative survival, and can never get down to the ground. Therefore, it is important to clarify the specific situation, which kind of craniotomy was done, and the condition of the patient after surgery, so that we can have a relatively accurate time.
