This study is a single-blind randomized clinical trial involving 40 adult patients undergoing elective open-heart surgery. The sample was allocated into two groups: 20 subjects in the oral carbohydrate fluid group and 20 subjects in the water group consumed 2 hours before surgery. Insulin resistance was measured by blood glucose levels, HOMA-IR index, and insulin tolerance tests. Postoperative outcomes were assessed by ICU stay duration, ventilator use, and hospital stay duration. Patient comfort factors were measured by hunger, thirst, nausea, and comfort levels.
