In that study of the transfusion practice of 146 European ICUs, the average hemoglobin at which patients were transfused was 84 ± 1.3 g/l [ 6].
The median (IQR (range)) Hb level at which patients were transfused: within guidelines was 6.9 g/dl (6.6 to 7.7 (4.8 to 13.9)); within guidelines, excluding cases of acute blood loss, was 6.6 g/dl (6.5 to 6.8 (5.5 to 6.9)); and outside the guidelines was 7.7 g/dl (7.4 to 8.2 (7.0 to 9.7)).
Until November 2009 we enrolled 380 patients undergoing elective cardiac surgery and randomly assigned 185 patients to a restrictive strategy of transfusion, in which red cells were transfused if the hematocrit concentration dropped below 24%, and 195 patients to a liberal strategy, in which transfusions were given when the hematocrit fell below 30%.
It should be noted that no information was available concerning which blood products were transfused, since their costs were not included in the database.
Further, we included patients with a preoperative haemoglobin level above 105 g/L that were transfused, which seems to deviate from current guidelines.
The HDS was defined as the number of transfusion sessions in which at least four RBC units were transfused.
To study whether fecundity was recovered in mice into which umbilical cord blood cells (UCBCs) were transfused after lethal-dose radiation, followed by transplantation of frozen thawed ovaries.
He remained an in-patient for one week, during which time seven units of blood were transfused to correct his Hb to 11.6 g/dl.
Children included in our study were transfused according to a restrictive strategy, which recommends transfusion for stable non-cyanotic PICU patients only if their Hb level drops below 70g/LL.
In July 2002, he underwent a protracted liver transplant operation in which, over 10 hours, 40 pints of blood were transfused into his body.
The open market would determine prices for more desirable blood like O (which is compatible with all blood types), compared with AB+, which can be transfused only with people of that blood type.
