ABSTRACT
Ectopic pregnancy is a common gynecological acute abdomen disease. Once the pregnant tissue is ruptured, it will rapidly develop into hemorrhagic shock or even death. In recent years, blood transfusion from the body is widely used in the rescue of intra-abdominal hemorrhage of ectopic pregnancy, which can reduce the time of cross matching and blood collection, reduce the risk of allogeneic blood transfusion, and enable patients with hemorrhagic shock to receive timely and effective treatment. Hemolysis caused by autologous blood transfusion is rarely reported. Once hemolysis occurs, if it is not handled in time, severe cases can occur acute renal injury, hyperkalemia, or cardiac arrest or even sudden death. We retrospectively analyzed the diagnosis and treatment of a patient with hemolysis after autologous blood transfusion, suggesting that the adverse reactions of blood transfusion occur not only in allogeneic blood transfusion, but also in autologous blood transfusion. It should be handled reasonably in clinical work to reduce the occurrence of similar complications.
