Transfusion therapy for severe anemia.
OBJECTIVE
We evaluated the safety and efficacy of a new transfusion regimen for children with severe anemia.


METHODS
Twenty-two consecutive patients with severe anemia (hemoglobin < 5 g/dl) of gradual onset requiring transfusion of packed red blood cells (PRBC) were studied. The transfusion regimen consisted of continuous infusion of PRBC at the rate of 2 cc/kg/h until the desired volume was given. Throughout the transfusion, the patients were closely monitored for any clinical signs of heart failure. The rise in hematocrit per 1 cc of PRBC/kg transfused was computed for each patient.


RESULTS
No patient developed any signs of cardiac failure or increase in the heart rate during or after the completion of transfusion. All patients had a decrease in the heart rate by the completion of transfusion. The mean decrease in the heart rate was 28% of the pretransfusion heart rate (range 12-44%). Excluding the four patients with sickle cell anemia, the remaining 18 patients had a mean increase in the hematocrit of 1.04% per 1 cc/kg of PRBC (range 0.85-1.28).


CONCLUSIONS
We conclude that for children with severe anemia of gradual onset requiring transfusion therapy, continuous transfusion of PRBC at the rate of 2 cc/kg/h is a safe and effective regimen resulting in an increase in the hematocrit of approximately 1% for each 1 cc/kg of PRBC transfused in all patients, except patients with sickle cell anemia.
