Prophylactic Use of Continuous Positive Airway Pressure to Operative Lung During One-Lung Ventilation Can Minimize Bleomycin Pulmonary Toxicity: A Report of Two Cases

Bleomycin, a common antineoplastic agent, is known to cause bleomycin pulmonary toxicity when the lungs are exposed to a high fraction of inspired oxygen (FiO(2)) level. Thus, intraoperative one-lung ventilation (OLV) is challenging in a patient with bleomycin treatment because maintaining high FiO(2) during OLV is a common practice in thoracic surgery to ensure adequate oxygenation while providing adequate lung isolation. We report two thoracic surgical cases where prophylactic continuous positive airway pressure (CPAP) was applied on the non-dependent lung during OLV while limiting FiO(2) to prevent postoperative respiratory complications.
