[Effect of one lung ventilation preconditioning on oxygenation during pediatric video-assisted thoracoscopic surgery].

Objective: To observe the effect of one lung ventilation (OLV) preconditioning on perioperative oxygenation during pediatric video-assisted thoracoscopic surgeries (VATS).

Methods: A total of 171 children aged 5 days to 11 years underwent VATS for empyema dissection and abscess excisions (n=55), mediastinal tumor resection (n=34), repair of the diaphragmatic hernia or diaphragmatic plication (n=21), pulmonary lobectomy or biopsy (n=43), or esophageal disease (n=18). Of these patients, 127 were younger than 3 years of age.
