OBJECTIVES: The effects of @entity417 of @entity3465 during @entity2107 ( @entity2107 ) as well as on the metabolic and erythropoietic functions were determined before and after a transfusion. Fourteen anemic (Hb range: 65-88 gm/L), @entity26 dependent (fraction of inspired @entity26 < or = 35%), nonventilated, preterm @entity1 with @entity2107 were studied at a postnatal age of 6 +/- 2 weeks. STUDY DESIGN: Cardiac output, heart rate, mean velocity of circumferential fiber shortening, shortening fraction (SF), and @entity64 volume were assessed by pulsed and continuous wave Doppler echocardiography. Values for resting @entity26 consumption, @entity544 production, and energy expenditure were obtained by indirect calorimetry. The affinity of oxygenated hemoglobin was determined by a blood @entity26 dissociation analyzer. RESULTS: An increased hemoglobin level resulted in a suppression of @entity1307 secretion (p < 0.001), whereas heart rate, cardiac output, @entity64 volume, and SF decreased (p < 0.05). @entity1017 before and after transfusion were similar. Plasma @entity880 levels decreased from 1.6 +/- 0.3 to 1.2 +/- 0.3. @entity26 consumption, @entity544 production, and energy expenditure were not affected. CONCLUSIONS: @entity417 of @entity3465 and @entity2107 increase heart rate, cardiac output, @entity64 volume, and SF. These hemodynamic compensatory responses are normalized by transfusion.
