It has been shown that combined POD can increase the incidence of postoperative pulmonary infections, deep vein thrombosis and decubitus ulcers, and increase the incidence of disability and mortality. The incidence of postoperative delirium in geriatric orthopedics is high.\n\nInvestigators conduct a prospective clinical study on geriatric orthopedic surgery patients to investigate the effect of oxytocin nasal spray on the prevention of postoperative delirium in geriatric orthopedic surgery. Cases were included according to the inclusion and exclusion criteria, and induction, maintenance and resuscitation were performed according to the standard protocol for general anesthesia.
