Biomarkers of Brain Damage and Postoperative Cognitive Disorders in Orthopedic Patients: An Update

Abstract EN

The incidence of postoperative cognitive dysfunction (POCD) in orthopedic patients varies from 16% to 45%, although it can be as high as 72%.

As a consequence, the hospitalization time of patients who developed POCD was longer, the outcome and quality of life were worsened, and prolonged medical and social assistance were necessary.

In this review the short description of such biomarkers of brain damage as the S100B protein, NSE, GFAP, Tau protein, metalloproteinases, ubiquitin C terminal hydrolase, microtubule-associated protein, myelin basic protein, α-II spectrin breakdown products, and microRNA was made.

The role of thromboembolic material in the development of cognitive decline was also discussed.

Special attention was paid to optimization of surgical and anesthetic procedures in the prevention of postoperative cognitive decline.
