Summary
Aging and preoperative complications like heart disease increase dementia risk during surgery. Minimizing postoperative stress and using local anesthesia can improve cognitive outcomes.
Area of Science:
- Gerontology
- Anesthesiology
- Neurology
Context:
- Perioperative cognitive changes are a significant concern in surgical patients.
- The Hasegawa's Dementia Scale (HDS-R) is a widely used tool for assessing dementia and delirium.
- Understanding risk factors is crucial for preventing cognitive decline.
Purpose:
- To investigate changes in intellectual status during the perioperative period.
- To identify preoperative, intraoperative, and postoperative risk factors associated with cognitive changes.
- To analyze factors influencing cognitive score improvement or deterioration.
Summary:
- This study examined 190 patients, assessing intellectual status changes using the Hasegawa's Dementia Scale (HDS-R).
- Preoperative risk factors included aging, cerebral vascular disease, myocardial infarction, arrhythmia, and diabetes mellitus.
- Postoperative risks involved hypoproteinemia and stressful conditions; local anesthesia correlated with improved scores.
Impact:
- Identifies key risk factors for perioperative cognitive dysfunction, aiding in patient risk stratification.
- Highlights the importance of optimizing patient condition before surgery and minimizing postoperative stress.
- Suggests local anesthesia as a potentially protective strategy against postoperative cognitive decline.
