Aim: Bleeding is a major problem in cardiac surgery, and results in a high risk of allogeneic blood transfusion associated with increased morbidity and mortality. In recent years, studies in the literature reported that desmopressin (1-deamino-8-D-arginine vasopressin, DDAVP) reduces the blood loss after surgical interventions. The aim of the present study is to analyze the effect of desmopressin and tranexamic acid on blood product use and postoperative bleeding in patients that were pretreated with P2Y12 inhibitors by cardiologists and undergone emergent coronary artery bypass grafting (CABG) surgery. Material and Methods:The prospectively collected data of 62 adult patients who underwent emergent isolated CABG surgery and pretreated with P2Y12 inhibitors by cardiologists were retrospectively reviewed. The perioperative data of the patients included their demographic data, laboratory findings, the amount of blood loss from chest tubes, the amount of blood product use, need of re-thoracotomy, morbidity and mortality. The patient population was divided into two groups: Group I: Patients that received tranexamic acid and DDAVP perioperatively (n=26); and Group II: Patients that received only tranexamic acid perioperatively (n=36). Results: The two groups of patients had similar characteristics at baseline. There was a statistically significant difference between Group I and II regarding postoperative blood loss from the chest tubes, re-thoracotomy, red blood cell and thrombocyte transfusions (p<0.05). No statistically significant differences were observed between the two groups in terms of fresh frozen plasma transfusion, inotropic support and mortality. Conclusion: We suggest that desmopressin in addition to tranexamic acid reduces bleeding and the amount of blood product use in patients undergoing emergent isolated CABG surgery.
