NCT07465510
One-lung ventilation is frequently required in thoracic surgery and is most commonly achieved using double-lumen endobronchial tubes (DLTs). Correct positioning of the DLT is crucial for effective lung isolation and patient safety. Fiberoptic bronchoscopy (FOB) is considered the gold standard for confirming DLT placement; however, it may not always be immediately available and requires specific expertise. Lung ultrasonography is a rapid, noninvasive, and bedside imaging method increasingly used in anesthesiology and critical care. This prospective observational study aims to evaluate the diagnostic performance of lung ultrasound in confirming the correct position of double-lumen endobronchial tubes in patients undergoing thoracic surgery. The results obtained from lung ultrasound will be compared with auscultation findings and fiberoptic bronchoscopy results. Fiberoptic bronchoscopy will be considered the reference standard. The sensitivity, specificity, positive predictive value, and negative predictive value of lung ultrasound and auscultation will be calculated.

This study aims to investigate the effect of a VExUS ultrasound guided protocol of perioperative fluid management within a goal-directed therapy framework, on postoperative respiratory complications, and the occurrence of acute kidney injury (AKI) in patients undergoing thoracic surgery.
NCT00515905
One-lung ventilation; organ protection; volatile anesthetics One-lung ventilation has become a common procedure for thoracoscopic surgery. Two hypothesis will be tested in this study: 1. Are inflammatory mediators increased in the re-ventilated lung after short-period pulmonary collapse? 2. Does Sevoflurane influence the production of inflammatory mediators in the re-inflated lung? Therefore, this study will elucidate the potential protective effect of a volatile anaesthetic (sevoflurane) on the production of inflammatory mediators by the respiratory compartment of the lung, i.e. the alveolar epithelium. * Trial with immunomodulatory product / biological
