Different Preoperative Psychological States on Postoperative Pain and Sleep Quality

Effects of Different Preoperative Psychological States on Postoperative Pain and Sleep Quality of Patients After Total Knee Arthroplasty

Severe knee osteoarthritis that is unresponsive to conservative treatment is effectively managed with total knee arthroplasty (TKA). Pre-operative anxiety is commonly seen among patients who are going to receive TKA, which also lead to increased anesthetics during the surgery. Some studies found that general anesthetics as an independent risk factor could result in a desynchronization of the circadian time structure and cause postoperative sleep disorders characterized by reduced rapid eye movement (REM) and slow wave sleep (SWS), which have signi?cant deleterious impacts on postoperative outcomes, such as postoperative fatigue, severe anxiety and depression, emotional detachment and delirium, and even pain sensitivity or postoperative pain of patients.
