Table 3 Red cell consumption and wastage based on the routinely used transfusion practice during the study period
Variables | |
|---|---|
Mean (median) duration between the first and the last transfusion (day) | 20 (14) |
Total number of the adult packs used | 221 |
Total number of transfusions | 250 |
Mean exposure to donor per neonate | 221/70 = 3.16 |
Percent of reduction in exposure to donor per neonate | 100 − (100(1 ×)/3.16) = 68.13% |
Mean transfusion number per neonate | 250/70 = 3.57 |
Number of satellite packs based on the mean transfusion number per neonate | 4 |
Mean transfusion number per unit | 250/221 = 1.11 ml |
Total Volume of transfused RBCs | 5000 ml |
Mean volume of transfused RBCs per transfusion | 5000 ml/250 = 20 ml |
Mean volume of transfused RBCs per neonate | 3.57 × 20 ml = 71.42 ml |
Total volume of wasted RBCs | 250 × 230 ml = 57,500 ml |
