Brief summary

Perioperative lung-protective strategies had been advocated in one-lung ventilation but normal respiratory functions were yet impacted during videoassisted thoracoscopic(VATS) surgery. The primary aim of this study was to investigate respiratory complications after OLVby using bedside lung ultrasonography combine with diaphragmatic ultrasonography.

Detailed description

Perioperative lung-protective strategies had been advocated in One-lung Ventilation(OLV) of videoassisted thoracoscopic(VATS) surgery but normal respiratory functions were yet impacted during general anesthesia, mechanical ventilation, loss of respiratory muscle tone and intrathoracic surgery. Lung ultrasonography has been confirmed to be a available tool for rapid confirming atelectasis, pleural effusion , pneumonia and pneumothorax. Diaphragmatic excursion were well correlated with vital capacity by lung function testing and diaphragmatic ultrasound imaging was demonstrated accurately to identify atrophy and impaired contractility or motion of the diaphragm.The primary aim of this present study was to investigate respiratory complications after OLV in the postoperative period by using bedside lung ultrasonography.The secondary aim was to evaluate the variation of lung ventilation during thoracoscopic surgery through lung ultrasonography combine with diaphragm ultrasound and assess the accuracy of ultrasound to confirm proper endobronchial intubation.
