Summary
Brief summary (as posted)
This study investigates the effect of apneic oxygenation of the non-ventilated lung on local and systemic inflammatory response during lung cancer surgery. Patients undergoing surgical resection of lung cancer often require one-lung ventilation during anaesthesia. This results in alveolar hypoxia accompanied by upregulated expression of inflammatory markers. Apneic oxygenation of the non-ventiladed lung may influence inflammatory processes and oxygenation during surgery. The aim of this study is to evaluate whether apneic oxygenation affects inflammatory markers in lung tissue and postoperative recovery in patients undergoing lung cancer surgery. The study is conducted at a single center and includes adult patients scheduled for elective lung cancer surgery. Data will be collected durig the perioperative period. The results of this study may contribute to improved anaesthetic management and patient outcomes during thoracic surgery.
