Vascular Access for Hemodialysis
Internal Arteriovenous Fistula; Shunt; Central Venous Catheter
Dialysis is the diffusion of solute molecules and fluids across a semipermeable
membrane. Dialysis is often necessary to sustain life in persons with no or very little
kidney function. The purpose of dialysis is to remove excess fluids, toxins, and
metabolic wastes from the blood during renal failure. Hemodialysis requires a vascular
access. This can be accomplished by surgically creating an arteriovenous (A-V) fistula
or graft (synthetic material used to connect an artery and a vein); or by insertion of an
external catheter into a large central vein.
The internal A-V fistula is made by surgically creating an anastomosis between an
artery and a vein, thus allowing arterial blood to flow through the vein, causing
engorgement and enlargement. Placement may be in either forearm, using the radial
artery and cephalic vein or brachial artery and cephalic vein. The internal A-V fistula is
the preferred access for long-term hemodialysis and must mature before it may be used
for access in hemodialysis. The central venous catheter may be either single- or double-
lumen. A single-lumen catheter serves as the arterial source, and the venous return is
made through a peripheral vein or by the use of an alternating flow device. A double-
lumen catheter is used for both the arterial source and the venous return. Because of
their location and low durability, femoral catheters are usually used only with inpatients
on a short-term basis. Central venous catheters can be used for weeks or even months
on an outpatient basis. External A-V shunts are currently considered obsolete. This care
plan focuses on both immediate and/or long-term care of the vascular access for
hemodialysis.
