PURPOSE: We evaluated the safety and efficacy of a new transfusion regimen for children with severe anemia. PATIENTS AND 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). CONCLUSION: 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.
