Table 2 Volume, timing and additional transfusion by study arm

From: Phase II trial of standard versus increased transfusion volume in Ugandan children with acute severe anemia

  Arm A: 20 ml/kg (Number = 82) Arm B: 30 ml/kg (Number = 78) Pvalue
Volume of initial transfusiona (ml/kg) – median (IQR) 20 (20 to 20) 30 (30 to 30) <0.0001
Rate of initial transfusiona (ml/kg/hr) – median (IQR) 5.7 (4.9 to 6.7) 7.6 (6.1 to 8.4) <0.0001
Time to initial transfusion (minutes) – median (IQR) 95 (75 to 128) 103 (75 to 130) 0.74
Total volume tranfused 0 to 48 hours (ml/kg) – median (IQR) 20 (20 to 20) 30 (30 to 30) <0.0001

  1. aRefers to blood infused before the first 30-minute break between aliquots of blood. This was the entire initial prescription for all but three children (all 30 ml/kg arm) where the last aliquot was given 49, 64, and 92 minutes after the previous aliquot; brefers to the number of prescriptions. IQR, interquartile range.
