Effects of Different Preoperative Oral Rehydration Protocols in Undergoing Thoracoscopic Radical Lung Cancer Surgery

This study aims to compare the new preoperative oral rehydration protocol (administering 50-100 mL of clear fluids or carbohydrate-rich beverages orally every hour until the patient arrives at the operating room) with the traditional preoperative protocol (consuming 200-300 mL of water orally two hours prior to surgery). The objective is to investigate the effects of these two protocols on the safety (e.g., risk of reflux and aspiration), comfort (e.g., levels of hunger, thirst, and anxiety), gastric emptying status (as assessed by gastric ultrasound indicators), and postoperative outcomes (e.g., incidence of postoperative delirium, insulin resistance, and inflammatory factor levels) in elderly patients undergoing thoracoscopic lung cancer radical surgery. This research seeks to identify a more appropriate preoperative rehydration protocol for elderly lung cancer patients.
