Postoperative Hemoglobin and Transfusion Rates Do Not Influence Revision of Head and Neck Free Flap in a Cohort of 259 Patients

Head &Neck, EarlyView.
ABSTRACT Introduction Recent literature advocates restrictive transfusion thresholds (Hb < 7 g/dL). The aim of this study was to evaluate if postoperative hemoglobin levels and transfusions influence Free Flap Revision (FFR). Methods This single center retrospective study included all patients who underwent head and neck surgery with free flap ...
