Hypertension, Pulmonary Clinical Trial
Official title:
Pulmonary Hemodynamic Effects of Stored Red Blood Cell Transfusion in Post-Operative Cardiac Surgical Patients: Influence of Breathing Nitric Oxide. A Randomized Controlled Trial in the Cardiac-Intensive Care Unit.
The objective of this study is to assess if prolonged storage time of a packed red blood cell unit may cause pulmonary vasoconstriction after transfusion, in a susceptible population such as cardiac surgery patients. The investigators will also evaluate the potential reversal effect of Inhaled Nitric Oxide on pulmonary vasoconstriction induced by stored blood transfusions.
Patients will be randomized into one of the three groups:
I. Blood transfusion stored for less than 10 days II. Blood transfusion stored for more than
30 days III. Blood transfusion stored for more than 30 days days plus inhalation of Nitric
Oxide at 80 part per million for an hour during blood transfusion.
