After 4.5 hours of hemodialysis, the hollow fibers of the dialyzer turned yellow. Biochemistry studies showed hyperbilirubinemia. The actual serum bilirubin (7.4?mg/dL) could be proved. Abdominal echography survey was negative. Hyperbilirubinemia was secondary to acute exacerbation of chronic viral hepatitis. http://www.selleckchem.com/products/erastin.html Anuria and skin hyperpigmentation in uremia lack the tea-color urine and mask clinical jaundice in the presence of hyperbilirubinemia. Careful observation of dialyzer yellowish discoloration gave us timely discovery of patient's hyperbilirubinemia. ""Rapid removal of small molecules during hemodialysis places an acutely ill patient with kidney failure at an increased risk of hemodynamic instability and for dialysis disequilibrium syndrome. The use of high-flux, high-efficiency (HEF) dialyzers may increase this risk despite reductions in blood and dialysate flow. We performed in vitro experiments to compare urea clearance at low dialysate flow and various blood flows using a low-efficiency low-flux (LEF) and a HEF membrane. Compared to LEF, there http://www.selleckchem.com/products/3-deazaneplanocin-a-dznep.html was a significant increase in the clearance of urea at all blood flows with the HEF (all P values? http://www.selleck.cn/products/pf-06463922.html as compared to LEF. Acutely ill patients require dialysis treatment that minimizes hemodynamic abnormalities and the risk of disequilibrium between blood and brain. These complications increase with rapid decline in plasma osmolarity mainly caused by movement of molecules from blood across the dialyzer membrane (the more efficient the dialysis, the faster the decline in plasma solutes). Urea removal rate is predominantly used as a surrogate for the efficiency of the dialytic process in terms of intra-dialytic osmolar decline. A recent trend toward the use of high-efficiency high-flux (HEF) dialyzer has been noted in hospitalized patients undergoing acute dialysis. This trend is because of a general belief that by reducing blood and dialysate flow rates the HEF dialyzer have similar solute molecule movement to that of the low-efficiency low-flux (LEF) dialyzer, thus it is reasoned that the use of HEF dialyzers are safe in acute settings. We have tested this reasoning by comparing urea clearances of HEF and LEF dialyzers in a set of in vitro experiments. Our findings are presented here. Fresenius F5 (LEF) and F180NR (HEF) dialyzers (Fresenius, Waltham, MA, USA) were utilized for the experiments using B Braun Dialog hemodialysis machine (Bethlehem, PA, USA). The F5 dialyzer has a surface area of 1.0?m2 and KOAurea of 472?mL/min.
