Correlation Analysis of POD and pNCD in Elderly Spinal Surgery Patients

To investigate the differences in serum indexes between elderly spinal surgery patients with postoperative delirium (POD) who either develop or do not develop long-term postoperative neurocognitive disorders (pNCD). Neurocognitive function of the study participants was assessed within one week before surgery using the Montreal Cognitive Assessment (MoCA). Compare changes in serum indexes level before and after surgery. Under routine anesthetic management of the Department of Anesthesiology and Surgical Operations at Xuanwu Hospital, endotracheal intubation general anesthesia was performed. Within 7 days post-surgery, delirium assessment was conducted using the Confusion Assessment Method (CAM), classifying patients into POD and non-POD groups. Neurocognitive function assessments were conducted long-term after surgery for the POD group to determine the presence of pNCD, further dividing the POD group into pNCD and non-pNCD subgroups, followed by serum indexes.By comparing the changes of serum indexes before and after surgery between the pNCD and non-pNCD subgroups, exploring the correlation of POD and pNCD.
