当院における血液製剤の使用状況，特に廃棄血液の現状について

Abstract

This study evaluated the usage and discard of all the blood products (124533 units) supplied from the Japan Red Cross blood center from April in 1989 to Marchin 1993.The units of fresh whole blood and stored whole blood purchased and used significantly decreased during 4 years. The units of fresh whole blood purchased was 22% in 1992 compared with those in 1989. The purchase and use of platelet concentrate significantly increased, especially in recent 2 years.The percentage of discarded blood was extremely lowered to 0.78% in 1992. Discards of whole blood and red cell concentrate due to inadequate management at the ward were especially decreased. The units of red cell concentrate discarded due to the expiration of stored period were also decreased because of the introduction of concentrated red cells stored in MAP solution (RC-MAP) in April 1992.Frequent communication between our division and the doctors in charge was necessary to reduce the discard of platelet concentrate which were over ordered for patients. In addition, the blood management system should be clearly understood among the doctors to reduce the discards of whole blood and red cell concentrate.
