Review <p>Background: Red blood cell transfusion is associated with <br />morbidity and mortality among adults undergoing cardiac <br />surgery. We aimed to evaluate the association of transfusion with morbidity among pediatric cardiac surgical patients. <br />Methods: Patients discharged after cardiac surgery in 2003 <br />were retrospectively reviewed. The red blood cell volume <br />administered during the first 48 postoperative hours was <br />used to classify patients into nonexposure, low exposure ( <br />15 mL/kg), or high exposure (&gt;15 mL/kg) groups. Cox <br />proportional hazards modeling was used to evaluate the as- <br />sociation of red blood cell exposure to length of hospital <br />stay (LOS).</p> - 0 0 http://www.iscs.org.ir/journals/vol.3/no.1/297/
