Is it necessary to stay in ICU after open-heart surgery for heart valve repair?

ICU refers to the hospital's Department of Critical Care Medicine, which is a medical department specializing in the treatment of critically ill patients. Relatively speaking, the medical and nursing team is relatively competent, and the medical equipment is advanced and complete. But the cost is high, and the family can not accompany, only in the designated time can visit. Surgical patients who are not awake from anesthesia also need to be resuscitated in ICU. At least until the condition is stabilized (vital signs are normal, stable respiration without ventilator, adequate urine output, no endotracheal intubation, or patients who have undergone tracheotomy), suitable for transfer to the general ward. If ICU is indicated, surgical ICU is preferred.
