Abstract
Introduction: A substantial amount of blood loss occurs during the open repair of aortic aneurysms or dissections. The aim of the present study is to determine the efficacy and cost-effectiveness of cell saver devices in blood conservation during the open repair of thoracic aortic pathologies. Methods: The present study prospectively collected the data pertaining to 25 patients who underwent surgical management of thoracic aortic aneurysms or dissections using a cell saver (Group 1, n = 25). The volume and cost of transfusion and postoperative outcomes were compared with the second group of patients who underwent surgery without the use of cell savers in the previous year (Group 2, n = 25); the data pertaining to the same were retrospectively collected from the hospital records. The patient characteristics and categorical variables were compared using the x2 test and Fisher’s exact test. Transfusion volume and costs were compared using the independent samples t-test and Mann–Whitney U test. Results: The patients in both the groups displayed similar characteristics and risk factors. The total volume of allogenic red blood cell (p < 0.001) and total blood product (p = 0.01) transfusions were significantly lower in Group 1. The cost of red blood cell (p < 0.001) and total transfusions (p = 0.03) were lower in Group 1. The two groups displayed similar in-hospital morbidity and mortality rates. Conclusions: There was a significant association between the use of cell savers and the decreased need for red blood cell and total blood product transfusions. Considering the cost of the cell saver set, transfusion costs in the two groups were comparable. © The Author(s) 2021.
