This prospective observational study aims to evaluate the effects of low-flow sevoflurane anesthesia on respiratory mechanics, gas exchange, and postoperative pulmonary function in patients undergoing one-lung ventilation (OLV) during thoracic surgery. The study will compare patients receiving low-flow sevoflurane anesthesia with those receiving standard-flow anesthesia, focusing on parameters such as lung compliance, arterial oxygen levels (PaOâ‚‚), and postoperative oxygen requirements. Fifty patients scheduled for elective thoracic surgery with OLV will be included. Data will be collected intraoperatively and postoperatively, and standard anesthesia protocols will be followed according to the attending anesthesiologist's preference. The results are expected to provide new insights into the safety and efficacy of low-flow anesthesia protocols in thoracic surgery, potentially guiding future clinical practice to reduce postoperative pulmonary complications.
