Overview
Brief Summary
This study is a prospective, single-center, randomized controlled trial to compare whether applying nutritional supplementation therapy before and after surgery in elderly patients aged 65 years or older undergoing non-cardiac surgery can reduce the incidence of postoperative delirium.

Eligibility Criteria
Inclusion Criteria
- •Elderly patients aged 65 and above.
- •Patients undergoing non-cardiac major surgery in thoracic surgery, lung cancer surgery, multi-level spinal surgery in neurosurgery and orthopedics, or liver cancer surgery in hepatobiliary and pancreatic surgery, under general anesthesia with an expected surgery duration of 2 hours or more.
- •Patients scheduled for arterial catheterization.
- •Patients who are able to take oral intake from postoperative day #1.
Exclusion Criteria
- •Patients with uncontrolled systemic conditions such as diabetes, hypertension, renal disease, liver disease, and other systemic illnesses.
- •Those with visual impairment.
- •Patients with cognitive impairment based on the Mini-Mental State Examination for Dementia Screening criteria.
- •Individuals experiencing difficulty in communication.

Outcomes
Primary Outcomes
incidence of postoperative delirium
Time Frame: from postoperative day 0 to postoperative day 7
Confusion assessment methods(CAM) will be used for diagnosing delirium At least two times a day during the hospitalization period. Patients diagnosed with delirium using the CAM were evaluated for the duration, symptoms, and type of delirium (e.g., reduced awareness of the environment; poor cognitive skills; behavioral changes; and emotional disturbances). \*\* Confusion assessment methods(CAM) diagnostic algorism (positive or negative result, positive means delirium) CAM is considered positive if features 1 and 2 are present, with at least one of features 3 or 4. Below are the four criteria of features : 1. Acute onset and fluctuating course Determined by collateral history or repeated clinic assessment 2. Inattention Counting from 20-1 is a simple (if blunt) test for this 3. Disorganized thinking 4. Altered levels of consciousness
Secondary Outcomes
- type of delirium(from postoperative day 0 to postoperative day 7)
- GDS for depression(from postoperative day 0 to postoperative day 7)
- IADL for independence(from postoperative day 0 to postoperative day 7)
- duration of delirium(from postoperative day 0 to postoperative day 7)
- K-FRAIL for frailty(from postoperative day 0 to postoperative day 7)
- ADL for independence(from postoperative day 0 to postoperative day 7)
- QOR-40 for recovery(from postoperative day 0 to postoperative day 7)
- SNSB-c for cognitive dysfunction(from postoperative day 0 to postoperative day 7)
- K-MoCA for cognitive dysfunction(from postoperative day 0 to postoperative day 7)
