To evaluate the effect of early postoperative oral carbohydrate on postoperative recovery of the unilateral knee arthroplasty
Currently, most clinical studies on the impact of oral carbohydrates on postoperative recovery are focused on the preoperative stage, with only a few small sample studies indicating that postoperative oral carbohydrates can improve patient comfort. Orthopedic surgery, especially joint surgery, requires patients to start functional exercise as soon as possible after surgery. Joint replacement surgery requires reducing the consumption of muscle tissue caused by protein breakdown. Perioperative nutritional support for patients is of great significance for postoperative muscle function recovery and good functional exercise. However, further systematic research on the impact of early postoperative oral carbohydrates on postoperative recovery is still lacking. This study selected patients who underwent unilateral total knee arthroplasty or single condylar arthroplasty. All surgical patients undergo homogenized preoperative preparation and intraoperative anesthesia management. Eligible patients were screened before surgery, and an informed consent form was signed. Patients enrolled in the experiment were randomly assigned into one of the three groups. They are the early feeding group (EOF1, EOF2group) and the late feeding group （control group）. Evaluate the effectiveness and safety of early postoperative feeding （EOF） in orthopedic surgery patients by measuring indicators such as insulin resistance index, QoR-15, and prealbumin and retinol binding protein.

After passing the evaluation by the anesthesiologist team in PACU, the EOF1 group drank 200ml of water. The evaluation criteria for the anesthesiologist team are: 1. Steward's awakening score is ≥ 6 points. 2. Level of sobriety ≥ 3. 3. There is no need to wait for intestinal peristalsis, based on the patient's wishes, and the feeding should be completed within 2 hours after the surgery.
After passing the evaluation by the anesthesiologist team in PACU, the EOF2 group had a drinking capacity of 200ml of 12.5% carbohydrates (100ml containing 12.5g of maltodextrin, fructose, and glucose). The evaluation criteria for the anesthesiologist team are: 1. Steward's awakening score is 6 points. 2. Level of sobriety ≥ 3. 3. There is no need to wait for intestinal peristalsis, based on the patient's wishes, and the feeding should be completed within 2 hours after the surgery.
Insulin resistance index at fasting
In the venous blood in an early morning fasting state, the change in the insulin resistance index can reflect whether the carbohydrate administration is favorable in the early postoperative period.
Time frame: 1 day after surgery
Insulin resistance index at fasting
In the venous blood in an early morning fasting state, the change in the insulin resistance index can reflect whether the carbohydrate administration is favorable in the early postoperative period.
Time frame: on the day of the surgery
Insulin resistance index at fasting
In the venous blood in an early morning fasting state, the change in the insulin resistance index can reflect whether the carbohydrate administration is favorable in the early postoperative period.
Time frame: 3 days after surgery
Pre albumin levels and retinol binding protein levels
The change in prealbumin levels and retinol-binding protein levels in venous blood in a fasting state in the early morning can reflect whether carbohydrate administration is favorable in the early postoperative period. Three of the eight test centers examined the pre-albumin levels and retinol-binding protein levels.
Time frame: on the day of surgery, 1 day and 3 days after surgery.
The 15-item recovery quality rating scale （QoR-15）
QoR-15 was used to assess five aspects of postoperative recovery quality (physical comfort, physical independence, psychological support, emotion and pain), with higher scores indicating the higher postoperative recovery quality. The lowest score is 0 points, and the highest score is 150 points.
Time frame: Up to 48 hours postoperative

After observing the vital signs for 30 minutes after surgery, patients in Group C were sent back to the ward to continue fasting and drinking for at least 6 hours. After the anus exhausts, they began to gradually drink and eat
The NRS score for the thirst thirst and hunger.
The Numerical Rating Scale (NRS) is used to assess the degree of thirst and hunger in patients, with a score of 0 to 10. A score of 0 represents no thirst and no hunger, while a score of 10 represents unbearable thirst and hunger. The thirst and hunger score indicates that early postoperative carbohydrate administration is beneficial.
Time frame: 2 hours, 6 hours and 8 hours after surgery
The degree of abdominal distension
Using grading method, complaining of abdominal distention, tolerable, feeling gas rolling in the abdomen, no obvious abdominal signs, mild abdominal distension, abdominal distention, moderate abdominal distension, vomiting, dyspnea, and significant abdominal bulge.
Time frame: 24 hours after surgery
Incidence of reflux aspiration and hypoxemia
Reflux aspiration is defined as severe cough followed by hypoxemia and lung rale after vomiting. Hypoxemia is defined as SpO2\<91% under air inhalation.
Time frame: 24 hours after surgery
Anal exhaust time
The advanced time of the first postoperative anal exhaust indicates a favorable early postoperative carbohydrate administration.
Time frame: Up to 48 hours postoperative
Incidence of postoperative nausea and vomiting
The lower the incidence and severity of postoperative nausea and vomiting, indicating that early administration of carbohydrates after surgery is beneficial.
Time frame: Up to 48 hours postoperative
Hospitalization time
The shortened length of hospital stay indicated that early postoperative carbohydrate administration was advantageous.
Time frame: Up to 7days postoperative
The extent of the postoperative pain
The total amount of sufentanil consumed by the patient 48 hours after operation, the number of effective presses of the analgesia pump, the number of times of rescue analgesia and the amount of rescue drugs were converted into the total amount of morphine.
Time frame: Up to 48 hours postoperative
Patient satisfaction score
Rated on a 0-10 scale, with a higher score representing greater satisfaction.
Time frame: Up to 48 hours postoperative
The incidence and severity of various adverse events （AE） from the start of oral carbohydrates until the end of the trial
The lower the incidence and severity of various adverse events (AE) from the start of postoperative oral carbohydrates until the end of the trial, it indicates that the early postoperative carbohydrate administration is beneficial.
Time frame: Up to 48 hours postoperative
Number of antiemetic uses
The less use of antiemetic drugs within 24h after the first start of postoperative administration indicates that early postoperative carbohydrate administration is advantageous.
Time frame: Up to 24 hours after the first start of drug administration.
