The study presents the data analysis (1) To find out the trend of blood component use during the period 2003-2010 and to determine impact of component awareness programs on reduction in whole blood (WB) and single unit transfusions. (2) To determine Hb trigger. The details about blood units issued were entered in the integrated blood bank management software as well as in Microsoft Excel. The data of 4,838 cases of pregnancy anemia; 2,244 receiving blood for obstetric (Ob) hemorrhage including 270 cases of disseminated intravascular coagulation; 1,413 women having Gynecological (Gy) bleeding; 911 Ob, 2,032 Gy and 740 surgeries for Gy malignancy were analyzed. During the years 2003-2010 there was gradual increase in component utilization for pregnancy anemia, Ob/Gy surgeries and Ob/Gy bleeding and significant reduction in WB transfusions due to component awareness programs. But single unit transfusions showed comparatively lower trend of reduction. The mean Hb was 6.4 g/dL for pregnancy anemia, 8.1 g/dL for surgeries and 7.3 g/dL for Ob/Gy bleeding.
