The aim of our study is to determine maximum surgical blood order schedule (MSBOS) in each surgical operation through analyzing usage of blood products at Bundang Jesaeng General Hospital. We investigated the amount of transfused red cells for each operation and calculated crossmatching-to-transfusion ratio (C/T ratio) and MSBOS. This was accomplished by referring to the Laboratory Information System program during 1 year from January through December 2003. Coronary artery bypass surgery and decompressive craniectomy showed the highest MSBOS in our hospital. The average C/T ratio was 3.2 and excessive reservations for blood products have been made for many operations. From this study, guidelines for the optimal blood ordering for each surgery were suggested.
