The Amount of Blood Use and Reorganization of Maximal Surgical Blood Order Schedule (MSBOS) in Elective surgery / 대한수혈학회지

ABSTRACT

BACKGROUND: Overpreparation of Red Blood Cells for elective surgery causes problems, such as returning of blood, inefficient task of the blood bank and waste of blood resources. At The National Medical Center, Maximal Surgical Blood Order Schedule(MSBOS) was organized for the first time in 1994. Recently, blood use is decreased as various transfusion side effects become known, and operation technique and anesthetic methods develop. As a result, we try to revise MSBOS investigating RBC utilization for elective surgery in 2002. METHODS: We investigated RBC utilization for elective surgery, the number of transfused patient, mean blood amount of all patient having been operated in. It was accomplished by referring to anesthesiologic records and blood delivery sheet at The National Medical Center during the 12 months from January through December in 2002. Average number of transfused units per patient of each operation was selected for MSBOS. RESULTS: For one year, the total number of surgery was 3,204, and transfusion was done in 1095 cases of surgery. Average transfusion rate is 34.4%. In 8 kinds of surgery(275 case, 9.3%), average amount of transfusion was under 0.5 unit and Type and Screen(T&S) is transduced for the elective surgery. Except for Cesarean section(C/S), blood use is decreased significantly, compared with the MSBOS organized at 1994. CONCLUSION: We could revise the guidelines for ordering blood on the basis of above results. And MSBOS should be revised at regular intervals, which can decrease blood disuse and medical cost.
