Yang Su,Haitao Yang,Xin Zheng, Analysis of Difference of Double Lung Ultrasound in Patients with Single Lung Ventilation Surgical Case Reports 2021 2613-5965 http://dx.doi.org/10.31487/j.SCR.2021.10.04 https://www.sciencerepository.org/analysis-of-difference_SCR-2021-10-104 Abstract: Objective: To retrospectively analyse the lung ultrasound images of 60 patients undergoing thoracoscopic partial pneumonectomy and compare the difference of bilateral lung ultrasound images. Results: B3 lines were predominant in ventilating side lung, B7 lines and atelectasis were predominant in operative side lung. Conclusion: Short-term lung injury after one-lung ventilation is mainly on the ventilation side, and the main manifestation is pulmonary edema.Keywords: Thoracoscopy, one-lung ventilation, ultrasound, pulmonary edema
