Generally, the major operating room need to be on the anesthesia, general anesthesia and so on; outpatient surgical history of the general local anesthesia can be done, so the outpatient operating room doctors less nurses are also less. The central operating room is a surgery routine 3-4 surgeons, in addition to an instrument nurse, an itinerant nurse, but also with an anesthesiologist. Specific surgeries vary from department to department, and the surgeries for different diseases in each department are also different and cannot be determined. After the surgery, the wound is routinely sutured, and then the patient goes into the anesthesia recovery room to recover for about half an hour, and after the anesthesia is almost recovered, the patient can be sent back to the ward to continue treatment.
