Intraoperative autologous blood transfusion: a systematic review of the literature

Abstract

Bleeding of the main health problems is intraoperative in hospitals, mainly. Control of adequate oxygen is essential for tissue oxygen. Autologous blood transfusion is used as a strategy to reduce the possibility of negative effects of allo transfusion and in situations of lack of donated blood. The aim of the study is to determine the importance and advantages of intraoperative autologous transfusion through a systematic review of studies addressing autotransfusion, published between 2016 and Busca2021. In studies, autotransfusion was mainly indicated in critically ill patients with massive bleeding induced by chest trauma associated with hemorrhagic shock, requiring emergency blood transfusion, where it is not possible to wait for blood preparation or where blood is lacking. In addition, its use has been reported in orthopedic surgeries such as total hip and knee arthroplasty. As benefits of lack of resources: reduction of benefits treatment resources, reduction of the need for local finance resources. No related complications were observed. In conclusion, despite the various advantages of autologous transfusion, published articles on the subject are still scarce. Thus, it is necessary to carry out clinical trials that compare the two methods, for the eligibility of the different perspectives of clinical application of each method in the trauma scenario.
