"Experimental Group:~6 hours before surgery, patients orally consumed 250 ml of a full-nutrition liquid (220 ml homogenized diet, 50 g; containing 31.4 g carbohydrates, 8 g protein, and 215 kcal).~2 hours before surgery, patients orally consumed 200 ml of a clear liquid (50 g enzymatically hydrolyzed rice powder + 0.5 g low-sodium salt; containing 47.7 g carbohydrates, 6.5 g whey protein, and 193 kcal).~After surgery, once there were no symptoms such as dizziness or vomiting, patients could start consuming clear liquids (containing 47.7 g carbohydrates, 6.5 g protein, and 221 kcal) orally every 30 minutes, 4 times on the day of surgery.~Starting from the first day after surgery, patients consumed 200 ml of fat-free nutritional liquid (50 g enzymatically hydrolyzed rice powder + 7.5 g isolated whey protein + 0.5 g low-sodium salt; 223 kcal) per serving, 4 to 6 times per day as needed."
