Postoperative delirium is an acute and fluctuating disturbance in attention, awareness, and thinking that may occur after major surgery. Patients undergoing robot-assisted radical prostatectomy may be at risk because of factors such as older age, general anesthesia, prolonged surgery, pneumoperitoneum, and steep Trendelenburg positioning. This single-center, prospective, two-arm controlled pilot study will evaluate whether preoperative deep breathing exercise training is associated with a lower occurrence of postoperative delirium in patients undergoing elective robot-assisted radical prostatectomy. A total of 50 patients will be included, with 25 patients in the breathing exercise training group and 25 patients in the control group. Patients in the breathing exercise training group will receive standardized, device-free deep breathing exercise instruction during the preoperative period, usually approximately one week before surgery. They will be asked to perform three sessions per day until surgery, with 10 deep breaths in each session. Patients in the control group will receive routine preoperative information without additional structured breathing exercise training. Postoperative delirium will be assessed during the first 48 hours after surgery using the 4AT and Nursing Delirium Screening Scale (Nu-DESC). The study will also evaluate postoperative oxygenation, oxygen requirement, pain, nausea and vomiting, respiratory complications, intensive care requirement, and length of hospital stay. The study will not alter routine anesthesia, surgery, or postoperative treatment, and no additional invasive procedures, laboratory tests, or imaging will be performed for research purposes.
