In general, as long as the patient’s vital signs after awakening from general anesthesia are stable and breathing is smooth, there is no limit to the duration of sleep. In the past, patients were required to remain awake for about 6 hours after general anesthesia to prevent inadequate metabolism of anesthetics and respiratory depression of patients during sleep. With the advancement of anesthesia technology, the types and dosages of anesthesia drugs used have been optimized, and postoperative patients are usually required to wear respiratory and cardiac monitoring devices, as well as oxygenation equipment when they return to the ward. If the patient’s liver and kidney function is normal, can normally metabolize anesthesia drugs, and the doctor’s surgical anesthesia medication mastery is appropriate, generally will not occur respiratory depression, so the postoperative period can be appropriate rest. In addition, general anesthesia after surgery patients are weak, also need to sleep to replenish energy. At this time, the family and the doctor by observing the monitor instructions, you can understand the patient’s basic vital signs, to determine whether there is a dangerous situation. After surgery, if the surgical incision site does not have special requirements, generally lying down for a period of time, try not to suddenly move, stand up, so as not to cause postural hypotension, easy to dizziness, unsteady, or even fall, resulting in unnecessary damage.
