Red cell volume and cardiac output in anaemic preterm infants.
To test the hypothesis that haemoglobin concentration is a poor predictor of benefit from transfusion in preterm infants, and that red cell volume is the most important indicator of anaemia, 24 preterm infants receiving red cell transfusions had red cell volume, haemoglobin concentration, and cardiac output measured before and after transfusion. Red cell volume was measured either using dilutio...
متن کاملInhibition of Red Cell Sequestration by Cortisone
The effect of cortisone on the sequestration of (a) antibody-coated red cells and (b) incubated red cells was studied in rats. Cortisone administration inhibited the hepatic sequestration of red cells altered by non-immune as well as by immune injury. There was a latent period of 2 days between the institution of cortisone therapy and its first manifest effect on hepatic sequestration. The sple...
متن کاملHaematocrit and red blood cell transport in preterm infants: an observational study.
AIMS To test whether cardiac output acts as a compensatory response to changes in haematocrit. METHODS A cohort of 38 preterm infants (27-31 weeks' gestation) was studied with repeated Doppler measurements of left ventricular output during the 1st month of life. Red blood cell transport was calculated when the duct was closed. RESULTS Multiple regression analysis showed that left ventricula...
متن کاملAtrial natriuretic peptide and blood volume during red cell transfusion in preterm infants.
Because raised plasma concentrations of atrial natriuretic peptide indicate volume expansion, we studied the effect of red cell transfusion on plasma atrial natriuretic peptide concentration, packed cell volume, and intravascular volume in eight preterm infants. Red cell transfusion increased red cell mass, packed cell volume and erythrocyte count, but decreased plasma volume. Total blood volum...
متن کاملAssociation between Red Blood Cell Transfusion and Bronchopulmonary Dysplasia in Preterm Infants
Anemia and the need for transfusion of packed red blood cells (PRBCs) are common in preterm infants. PRBC transfusion increases the oxygen carrying capacity of hemoglobin and may result in higher rates of organ dysfunction. To determine whether PRBC transfusion in preterm infants is associated with an increased incidence of bronchopulmonary dysplasia (BPD), this retrospective study was performe...
