Study of Acupuncture on Postoperative Delirium in Patients With Diabetes Mellitus

Regional Saturation of Oxygenation (rSO2)

The brain oxygen saturation monitoring electrode was attached to the forehead, and the baseline level (T0) was recorded after the reading was stable under the condition of air inhalation. rSO2 readings were recorded after induction (T1), at the beginning of surgery (T2), one hour after the beginning of surgery (T3), at the end of surgery (T4), and after extubation (T5). The maximum and minimum values of rSO2 readings during surgery were recorded, and the area under the rSO2 curve was recorded when the rSO2 reading decreased by 13% from baseline for more than 5 minutes. rSO2 values of each time point, maximum and minimum values during surgery.

Time frame: Intraoperative

Visual Analogue Score (VAS)

Record VAS. VAS is a psychometric response score. Draw a 10 cm horizontal line on the paper. The end of the line is 0, indicating no pain; the other end is 10, indicating severe pain. The middle part shows different levels of pain.

Time frame: at 8 a.m. and 16 p.m. daily for 3 days after surgery

Blood glucose levels

record blood glucose levels

Time frame: Entering the operating room, the time when the surgery ends

Expression of reactive oxygen species (ROS), superoxide dismutase (SOD), S100β in serum

The inflammation level will be assessed.

Time frame: Entering the operating room, the time when the surgery ends

Expression of peroxisome proliferators-activated receptor-γcoactivator-1α (PGC-1α)

assess the expression of PGC-1α

Time frame: Entering the operating room, the time when the surgery ends
