Flashcards in Week 11 Dialysis access scanning Deck (21):
1

What is the purpose of kidney dialysis?

To eliminate waste and excess water from the blood.

2

What are the 4 types of dialysis access?

  1. Peritoneal dialysis
  2. Dialysis cathere
  3. AVF
  4. AVG

3

Where can peritoneal dialysis be done?

Home.

4

What is an advantage of peritoneal dialysis?

DOes not require major surgery, less complications.

5

How often can peritoneal dialysis be done?

Each night or daily.

6

What is a major problem with peritoneal dialysis?

Infection.

7

Where is a dialysis catheter usually tunneled into?

Prox. IJV

8

How long is a dialysis typically used for?

Less than 3 months.

9

What us a major downfall of a dialysis cathere?

Prone to infection.

10

What is the function of a catheter?

Takes venous blood out for dialysis and the other catheter returns cleansed blood to the artery.

11

What are the 2 types of dialysis access?

  1. Fistulas
  2. Grafts

12

What is a fistula?

It is a direct connection between artery and vein.

13

What is brecia-cimino fistula?

Radial artery to cephalic vein @ wrist→1 anastom.

14

What are the 2 typical grafts used for dialysis access?

  1. Transposed veins.
  2. PTFE

15

What are the 2 anastomoses?

Arterial anastomoses and venous anastomoses with graft between them.

16

What are the 2 types of graft shapes?

Straught and loop grafts.

17

What is a hemodialysis access?

SUrgical attachment of artery and vein via fistula or graft to increase flow in vein for repeated puncture by catheter to dialysis equipment.

18

Where is a hemodialysis usually done?

Non-dominant arm.

19

What does a hemodialysis access do to veins?

  • Lumpy
  • Thrill can be palpated
  • Vein gets larger

20

What is basic hemodialysis diffusion?

High pressure artery to low pressure vein.

21

What do AV fistulas and AV grafts do?

  • Takes blood from a distal arterial bed directly into venous system.
  • Creates high flow rates.
