Elective Major Abdominal Surgery Clinical Trial
Official title:
Postoperative Neurocognitive Dysfunction After Major Abdominal Surgery: A Prospective Observational Cohort Study
Predisposing and precipitating factors for perioperative delirium for the elderly remain elusive. This research will be conducted to determine risk factors of postoperative delirium.
This study intends to include 500 participants over 65 years old undergoing elective abdominal major surgery. The primary outcome is incidence of delirium at 7 days postoperatively, and the secondary outcomes include preoperative sleep disorders(Athens In-somnia Scale, AIS), postoperative cognitive impairment (Abbreviated Mental Test Score, AMTS), postoperative pain (NRS pain score), incidence of significant postoperative complications, length of hospital stay, and serum biomarkers levels. ;
