While it has generally been accepted that a 3% change in hematocrit is equivalent to a 1-"unit" loss of blood, few studies have been published to actually document this. A more complete understanding of this correlation would be helpful in estimating blood loss from changes in hematocrit in patients sustaining hemorrhage as well as in those receiving transfusions. In this retrospective study, we analyzed the post-transfusion alterations in hematocrit from 61 independent transfusions in 48… CONTINUE READING
