Algorithm-Guided Transfusions in Cardiac Surgery Patients for Reduction of Drainage Blood Losses (HEART-PoC)

June 12, 2015 updated by: Michael Sander

Monocentric Pilot Study of Algorithm-Guided Transfusions in Cardiac Surgery Patients for Reduction of Drainage Blood Losses

Cardiac surgery patients have a risk to need allogeneic blood transfusions that depends on several risk factors, e.g. the type of surgery, concomitant medication with anticoagulants, and postoperative chest tube output. Allogeneic blood transfusion is associated with transfusion reactions, infection transmission, and postoperative morbidity and mortality. The aim of this study is to investigate, whether cardiac surgery patients have a reduced postoperative chest tube output and transfusion need when using a point-of-care guided transfusion algorithm compared to standard of care transfusion protocols.
