|Anemia Treatment Among Patients Suffering From Left Ventricular Systolic Dysfunction||Drug: furosemide Drug: placebo normal saline|
More than 4 million patients receive a blood transfusion each year in the United States, many of them suffer from congestive heart failure. The reported prevalence of anemia in CHF is unknown, ranges widely from 4% to 70%, due to a lack of an established, consistent definition of anemia in CHF.
Treating CHF patients with furosemide prior to blood transfusion became a common practice, even though no randomize clinical trial had examine this issue. Nand et al. measured the pulmonary capillary wedge pressures in 20 adults with chronic severe anemia (Hg <6 mg/dl) and no systemic disease before and after transfusion of 700ml of whole blood. Ten of these patients were treated with furosemide (40 mg intra-venous) immediately prior the transfusion. The PCWP had increased significantly among patient who did not receive the furosemide and decreased by 3.75% among patients in the furosemide group, although this change was not was statistically significant. In another study, the same group of Nand et al. measured the PCWP among 40 chronic anemia patients receiving blood transfusion. None of the patients suffered from cardiopulmonary disease. The patients were randomly divided into 4 groups: the difference between the first 3 groups was the speed of the transfusion (2 ml/min, 5 ml/min and 10 ml/min). The fourth group patients were treated with 40 mg of furosemide before the transfusion was given in a rate of 5 ml/min. The PCWP increased significantly in the first 3 groups, with the rise being proportionately greater with faster transfusions (15.8, 20.9 and 32.2% in groups A, B and C, respectively). In the furosemide group, however, the PCWP decreased significantly by 21.7%.
