OBJECTIVES Transfusion of blood products has been associated with increased risk of post-pneumonectomy respiratory failure. It is unclear whether intraoperative or postoperative transfusions confer a higher risk of respiratory failure. Our objective was to assess the role of transfusions in developing post-pneumonectomy respiratory failure.
