Frailty is a multidimensional syndrome of physical functional, cognitive, and psychological decline. Frailty tends to increase the vulnerability to stress of the body, which leads to increased postoperative complications, prolonged hospital stay, and even higher mortality. Along with the accelerating process of aging in society, more and more elderly patients require surgical treatment. Such patients are prone to cognitive dysfunction after surgery. Frailty is a common comorbid state in elderly patients, but the effect of frailty on postoperative cognitive function in elderly patients has not been fully clarified. In this paper, we summarize the research on postoperative delirium, postoperative cognitive dysfunction and postoperative cognitive improvement in the elderly with frailty, providing ideas for clinical research on frailty and postoperative cognitive function. |
