Brief Summary
The goal of this [type of study: observational study ] is to [compare Energy differences in various bands of intraoperative electroencephalogram in elderly patients with postoperative delirium and non delirium.] in [describe participant population selected 69 patients who underwent laparoscopic radical surgery for colorectal cancer on a selective basis]. The main question[s] it aims to answer are:

Detailed Description
The goal of this [type of study: observational study ] is to [compare Correlation between EEG data and postoperative delirium in elderly patients undergoing colorectal cancer radical surgery under preoperative frailty monitoring.] in [describe participant population selected 69 patients who underwent laparoscopic radical surgery for colorectal cancer on a selective basis]. The main question[s] it aims to answer are:
• [Is there any difference in the spectral range of EEG between POD patients and non POD patients] Participants will [Sedline EEG monitoring electrodes were placed 1cm above the eyebrows on both sides of the patient and at the temples on both sides, and were continuously monitored from the start of anesthesia in the operating room until the end of the surgery.Pay close attention to the vital signs and wait for the patient to fully recover and the vital signs to basically return to the preoperative level before returning to the ward.•Assessment of cognitive function using the Mini Mental State Scale (MMSE) 1 day before surgery and 7 days after surgery.•Preoperative assessment of frailty using the frailty screening scale.•Assess delirium using the ICU Patient Ambiguity Assessment Form (CAM-ICU) 1 day, 2 days, 3 days, and 7 days after surgery.].

Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Non-delirious group No postoperative delirium occurred |

Outcome Measures
Primary Outcome Measures
- Postoperative delirium [1 day, 2 days, 3 days, and 7 days after surgery]
Assessing delirium using the ICU Patient Ambiguity Assessment Form (CAM-ICU)
- EEG power of each band [During the procedure]
Recording frontal lobe electroencephalogram using a sedline root monitor (Masimo, Crop)
- The number of minutes of suppression assessed by visual analysis of the EEG [Throughout the operation]
The burst suppression time was calculated by EEG visual analysis
