What does dialysis vascular access mean?

Access to blood: Hemodialysis needs access to blood to run high speed flow about 12-15 oz of blood per minute. This requires a larger line under the collar bone which is a temporary method or a surgery to connect the veins of arm with an artery which pours great flow of blood into the vein. The vein will get larger and can be stuck with a needle to make access to blood easy. A plastic tube may be used, a graft. ...Read more

Dialysis (Definition)

Simple answer is that it is a medical technology used primarily to provide an artificial replacement for lost kidney function in people with renal failure. Hemodialysis remove wastes and excess water from the blood by circulating blood outside the body through an external filter, called a dialyzer. Blood and dialysate flow through in opposite directions and the ...Read more

Can Ccr be 9.7 ml/min if S.Creatinine is just 2.37 mg/dl? S. Cr is consistent for 3 yrs. Does that mean I need dialysis, or it may be lab error?

Can Ccr be 9.7 ml/min if S.Creatinine is just 2.37 mg/dl? S. Cr is consistent for 3 yrs. Does that mean I need dialysis, or it may be lab error?

Subscientific: This pathologist doesn't believe in the "estimated GFR's" from spot creatinines. The idea of dialyzing somebody with a creatinine 2.3 is bolt stupid. I'll bet your nephrologist -- if you've even been referred -- will tell you the same thing. Just watch your diabetes and your hypertension and hopefully we can keep this under control. ...Read more

End-stage renal disease means you need dialysis?

End-stage renal disease means you need dialysis?

When kidneys fail: End stage renal disease is stage five ckd or GFR 15 or less. Dialysis is started when the function of the kidneys is inadequate to remove the metabolic byproducts of metabolism. In practice this is usually determined by measuring gfr. Most people have to start dialysis when GFR drops to 10-15 though it may have to be started higher or lower than that. ...Read more

What are the negative effects of dialysis access surgery?

Dialysis Access: You may be preparing for kidney dialysis by getting a "fistula"- a surgically created connection between an artery and vein. You may be having a peritoneal access port placed in your abdomen. Or you may be having both! All surgeries carry risks of infection, bleeding, damage to tissue, and allergic reaction. But starting dialysis with a central IV line carries risks, too. We say, "Fistula first!" ...Read more

What does it mean when a dialysis patient clogs the dialysis machine?

Kidney machine clog?: I am not sure what you are referring to by a dialysis patient's clogging of a kidney machine. Patients can have their dialyzer (d), the artificial kidney, during dialysis. This normally occurs when the patients are not getting enough Heparin during dialysis and their d's clot ending their use of that d. If that is not the answer you were looking for, ask the patient's nephrologist youyr question. ...Read more
