Background: Recently, operation technology and health care environment are continuously improving and changing. An updated MSBOS using current blood usage data is necessary for efficient blood management in the hospital blood bank. Methods: This study was a retrospective analysis based on operation names according to the ICD-9-CM at Severance hospital in 2013. We calculated the average units of red blood cells according to each operation, as well as the total units of RBCs used per each operation and patient. Finally an average unit of RBCs was set for the MSBOS, which were ordered before surgical operation. These analyzed results were compared with the previous reports of our hospital and other hospitals. Results: Transfusion episodes occurred in 3,092 cases, which is only 8.6% of all patients. Total transfused units were 8,230 units, 27% of total RBCs (2,270 units) transfused were used in cardiovascular surgery. Compared with the previous data, the usage of RBCs during surgery was decreased. Conclusion: The MSBOS investigated in this study showed some differences in the indicators in 2007. Therefore, regular update of the MSBOS is necessary in each hospital to reflect the advancement of surgical technology. (Korean J Blood Transfus 2015;26:38-46)
. Previously, anti-D was the most commonly detected Rh antibody, but its incidence has greatly decreased due to the prophylactic use of Rh immunoglobulin (RhIG). Anti-D antibody formation may occur following RhD-incompatible organ transplantation when D-recipients are exposed to D+ RBCs that originate from a donor organ. As a large volume of donor blood may be contained within the transplanted organ, the use of a large amount of RhIG is required in RhD-incompatible liver transplantation. Here, we describe the use of a large amount of RhIG to treat a patient following RhD-incompatible liver transplantation. This patient was a 71-yr-old woman with hepatitis C virus-related liver cirrhosis, who had an A/D-blood type. The donor was her grandson, whose blood type was O/D+. The recipient's preoperative anti-D antibody test was negative. One unit of O/D-irradiated leukoreduced RBCs and three units of A/D-fresh frozen plasma were transfused during liver transplantation. An equal amount (12,000 IU) of RhIG was infused intravenously, immediately after liver transplantation and a second time on post-operation day 1. The anti-D titer was 1:64 on the first post-operation day, and had increased to 1:128 by the following day. By 1 month after the surgery, the titer had decreased to 1:4. In this case of liver transplantation, RhIG was actively used to prevent RhD sensitization and the subsequent occurrence of adverse events associated with RhDincompatible liver transplantation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
