Plasma Proteomics in Patients With Postoperative Delirium

Overview

Patients undergoing cardiac surgery were recruited. Baseline characteristics of all subjects were collected. The 3-minute Delirium diagnostic Scale (3D-CAM) was used to screen the POD group and non-POD group from the recruited subjects during the first 7 days after surgery. Peripheral blood samples were collected 1 day before surgery and 2 day after surgery. . Plasma was isolated from peripheral blood for subsequent proteomic analysis.

Patients undergoing noncardiac surgery were recruited. Baseline characteristics of all subjects were collected. The 3-minute Delirium diagnostic Scale (3D-CAM) was used to screen the POD group and non-POD group from the recruited subjects during the first 7 days after surgery. Peripheral blood samples were collected 1 day before surgery and 2 day after surgery. Plasma was isolated from peripheral blood for subsequent proteomic analysis. To study the characteristics of proteins on a large scale, including protein expression levels, post-translational modifications, protein-protein interactions, etc., so as to obtain a comprehensive understanding of disease occurrence, cell metabolism and other processes at the protein level. Assessment of imbalanced protein expression in peripheral blood using protein profiling may allow us to better understand the pathological changes occurring at the molecular level of POD. Early detection of patients at high risk of POD can optimize perioperative management and promote rapid postoperative recovery.
