Brief Summary

This prospective randomized controlled study will be aimed to evaluate the effect of preoperative oral carbohydrate loading on the elderly patient's quality of recovery and satisfaction in undergoing knee arthroplasty (TKA) surgery with spinal anesthesia.

Detailed Description

As an essential aspect of enhanced recovery after surgery, the advantages of preoperative oral carbohydrate loading (eg, improving patients' comfort during preoperative preparation, reducing nausea and vomiting, and reducing insulin resistance) have been shown by a large number of studies.

This study will be conducted as a single-center, prospective, randomized, double-blinded trial in a university hospital. Elderly ( \> 65) patients scheduled for elective TKA will be screened for enrollment in the study. Patients will be randomized into an oral carbohydrate group (Group OC), and an oral placebo group (Group OP). Solid food will be forbidden starting at 20:00, and drinking will be banned after 22:00 the day before surgery. Oral carbohydrate preload will be administered to the Group OC. In Group OP, the blinded researcher will give an equal volume of placebo fluid orally at 22:00 and 2 hours before the operation in the ward. The participant will record that the liquid has been completely consumed

Primary Outcome Measures
NameTimeMethod
Quality of Recovery-15 scorePostoperative 24th hour

Minimum value: 0, Maximum value: 150, higher scores mean better.

Secondary Outcome Measures
NameTimeMethod
Patient mobilization48 hours

Patient reporting time of first standing to the side of the bed and time up and go test 2 days

Quality of Recovery-15 scorepreoperative, postoperative day 7

Minimum value: 0, Maximum value: 150, higher scores mean better.

Numerical Rating Scale24 hours

Range 0-10, 0=no pain, 10=the worse pain ever.

Opioid consumption24 hours

Opioid consumption

Patient well-being (thirst, hunger, mouth dryness, nausea and vomiting, fatigue) will be assessed just before the operating room admissionpreoperative

5: very satisfied, 4: somewhat satisfied, 3: neutral, 2: somewhat dissatisfied, 1: very dissatisfied

Sleep Quality measured with Likert ScaleOne week after surgery

Patients' perceived sleep quality will be assessed with a Likert scale. Likert scale is scored from Likert scale where 1 = very dissatisfied, 2 = dissatisfied, 3 = neutral, 4 = satisfied and 5 = very satisfied

Range of knee motion48 hours

Range of knee motion

Glucose measurementPostoperative 24th hour

Glucose measurement

Mini Mental State Examinationpreoperative and postoperatve day 1

Mini Mental State Examination Scale (This scale is a 30-point questionnaire that is used extensively in clinical and research settings to measure cognitive impairment. Any score of 24 or more (out of 30) indicates a normal cognition. Below this, scores can indicate severe (≤9 points), moderate (10-18 points) or mild (19-23 points) cognitive impairment.)
