Efficacy of Intravenous Iron Therapy in Maintaining Hemoglobin Concentration on Patients Undergoing Bimaxillary Orthognathic Surgery

Bimaxillary orthognathic surgery is widely used to correct dentofacial anomaly and bimaxillary prognathism. However, the complicated vascularity of the surgical site and limited visual field can lead to unexpected bleeding. Intravenous iron isomaltoside 1000 (monofer®) significantly increased the hemoglobin level and prevented anemia 4 weeks after cardiac surgery. The aim of this study is to evaluate the effect of Intravenous iron isomaltoside on maintaining hemoglobin concentration in patients undergoing bimaxillary orthognathic surgery. Fifty-eight patients, aged 19 to 40 years, scheduled for Bimaxillary orthognathic surgery will be divided into monofer (n=29) and control (n=29) groups. Randomly selected patients of the ulinastatin group are given intravenous iron isomaltoside. In contrast, patients in the control group receive an equivalent volume of normal saline as a placebo. The primary endpoints are postoperative hemoglobin concentration.
