continuous renal replacement therapy (CRRT) — continuous renal replacement therapy (CRRT) is a form of dialysis therapy used in critical care settings. The benefit of CRRT for critically ill patients is that it runs slowly (generally over 24 hours to several days) allowing for removal of excess fluid and uremic toxins with less risk of ...
Diagram showing the basic physiologic mechanisms of the kidney. The renal clearance ratio or fractional excretion is a relative measure of the speed at which a constituent of urine passes through the kidneys. [1] [2] It is defined by following equation: =
SCUF is a continuous renal replacement therapy (CRRT) generally used to remove fluid from fluid overloaded patients with acute kidney failure. During SCUF blood is continuously removed from the body, passed through an extracorporeal circuit through a hemofilter , and send back to the body.
where C is the concentration [mol/m 3]; t is the time [s]; K is the clearance [m 3 /s]; V is the volume of distribution [m 3]; From the above definitions it follows that is the first derivative of concentration with respect to time, i.e. the change in concentration with time.
Hemofiltration is sometimes used in combination with hemodialysis, when it is termed hemodiafiltration. Blood is pumped through the blood compartment of a high flux dialyzer, and a high rate of ultrafiltration is used, so there is a high rate of movement of water and solutes from blood to dialysate that must be replaced by substitution fluid that is infused directly into the blood line.
Central to the physiologic maintenance of GFR is the differential basal tone of the afferent and efferent arterioles (see diagram). In other words, the filtration rate is dependent on the difference between the higher blood pressure created by vasoconstriction of the input or afferent arteriole versus the lower blood pressure created by lesser ...
Kidney transplant or renal transplant is the organ transplant of a kidney into a patient with end-stage kidney disease (ESRD). Kidney transplant is typically classified as deceased-donor (formerly known as cadaveric) or living-donor transplantation depending on the source of the donor organ.
