Study of ERAS-Based Preoperative Nutrition Education and Fasting Effects on Hydration and Nausea After Total Knee Replacement Surgery

What this Trial Is About

This research aims to evaluate how following a preoperative nutrition education and fasting protocol based on Enhanced Recovery After Surgery ERAS guidelines affects postoperative hydration and the occurrence of nausea and vomiting in patients having total knee arthroplasty. Total knee arthroplasty is a common surgery, especially in older adults, where recovery can be complicated by surgical stress, anesthesia issues, dehydration, and nausea. Optimizing nutrition and hydration before surgery may improve these outcomes. Participants will be randomly assigned to one of two groups. One group will receive ERAS-based nutrition education along with a standardized fasting protocol to follow during the 24 hours before their surgery. The other group will receive routine preoperative care without the ERAS protocol. These treatments are behavioral and focus on education and fasting management according to evidence-based guidelines designed to reduce prolonged fasting and improve comfort. During the study, participants will be monitored for postoperative hydration levels, nausea and vomiting severity, and fluid intake and output balance within the first 48 hours after surgery. Validated tools like the Surgical Thirst Discomfort Scale and Rhodes Index of Nausea, Vomiting, and Retching will be used. Data on these outcomes will help understand the impact of the ERAS protocol on recovery and inform nursing care improvements. The study will involve preoperative education, surgery, and at least 48 hours of postoperative follow-up.
