BACKGROUND: Most incident hemodialysis (HD) patients who initiate dialysis therapy with anemia usually can achieve a hemoglobin (Hb) level of 11 g/dL or greater (> or =110 g/L) within a few months of the initiation of recombinant human erythropoietin (EPO) therapy. However, patients unable to achieve this level may be ...

Vascular access (VA) is mainly a problem confronting patients undergoing hemodialysis (HD). In some cases, peripheral veins are damaged or thrombosed because of repeated vein punctures and subsequent thrombophlebitis or accompanying ailments like diabetes or other kinds of vasculitis, making the use of conventional VA methods unsuitable. In this study, ...
