| Postoperative delirium (POD), a common surgical complication, refers to the acute and fluctuating disturbance in attention and awareness after surgery, which seriously affects the recovery and is one of the predictors of poor prognosis of patients. At present, preoperative anxiety is common in perioperative patients. As the independent risk factors for POD, preoperative anxiety plays an important role in the occurrence and development of POD. Taking active and reasonable intervention measures for patients with preoperative anxiety may effectively reduce the occurrence of POD. This paper reviews the effects of preoperative anxiety on POD, focusing on its mechanism and prevention methods, in order to explore the relationship between preoperative anxiety and POD, which might provide new ideas for the clinic． |
