The length of stay in the ICU after two craniotomies is variable, depending on the patient’s condition and postoperative recovery. For most patients undergoing craniotomy, if the surgery goes well, the patient’s basic vital signs are stable and spontaneous respiration is restored, and the patient can be transferred to the general ward to continue treatment, usually within one week. If the patient’s primary disease is more serious, such as massive cerebral hemorrhage secondary hemorrhage, severe cerebral contusion secondary brain hernia, etc., it usually takes a longer time for the patient to regain stable basic vital signs, and if it is a brain stem injury, the patient may not breathe on his own for a long time, and needs to use a ventilator for a long period of time to assist ventilation, and at this time, the patient’s stay in the ICU will be longer. The hospitalization time after two craniotomies can be consulted with a medical professional.
