Effect of Perioperative IV Ibuprofen on Cerebral Oxygenation and Postoperative Cognition During One-Lung Ventilation

This study compares the effects of ibuprofen administered during surgery and within the first 24 hours after surgery, versus no ibuprofen, on cerebral oxygenation, postoperative changes in consciousness (postoperative delirium and cognitive dysfunction), length of stay in the intensive care unit, and the incidence of postoperative pain, nausea, vomiting, and pruritus in patients undergoing lung lobectomy or segmentectomy using a closed (video-assisted) method (VATS - video-assisted thoracoscopic surgery), in whom one-lung ventilation is applied. The aim of this study is to evaluate the effects of ibuprofen on cerebral oxygenation, postoperative cognitive changes, and delirium in patients undergoing one-lung ventilation.
