Under normal circumstances, surgeries are generally performed during the day.
If there are fewer surgeries, they are mostly scheduled for the morning.
For a 9 a.m. surgery, nurses typically advise the patient and family the night before to abstain from food and water. The purpose is to prevent anesthesia-related risks during the surgery.
After anesthesia, muscles relax, food can reflux into the airway, and suffocation can easily occur.
Some patients may experience incontinence during surgery, which will certainly pollute the operating room environment, and negatively impact the feelings of the medical staff.
This patient's surgical plan was discussed around noon, and the surgery was scheduled for the evening, indicating that the patient and family might be pressing urgently.
Another possibility could be that the surgeon has other plans for tomorrow and decides to work overtime to perform the surgery tonight.
