The Effect of Iloprost on Oxygenation During One-lung Ventilation for Lung Surgery

May 1, 2019 updated by: Wonjung Hwang, Seoul St. Mary's Hospital

The Effect of Iloprost on Arterial Oxygenation and Shunt Fraction During One-lung Ventilation for Lung Surgery

During one-lung ventilation in patients undergoing thoracic surgery, the persistent flow in the non-ventilated lung increases intrapulmonary shunt and decreases systemic arterial oxygenation. This prospective, randomized, double blind study was conducted to evaluate the effects of inhaled iloprost during one-lung ventilation on arterial oxygenation and shunt fraction during thoracic surgery.
