Dialysis Flashcards
Performing dialysis care
4 hour treatment 3 times a week
Complications of hemodialysis
Blood infection, thrombosis, and internal bleeding d/t adding anticoagulants
Peritoneal dialysis
Fluid is put into the abdominal cavity via a catheter and then removed to clean your blood.
How long does the fluid remain in the body? And why?
For several hours, allowing exchange and equilibrium with blood before being discarded
Benefits of peritoneal dialysis
More flexible, less restrict on diet, longer lasting that hemodialysis
What is hemodialysis?
Blood being filter outside the body in a dialysis machine then cleansed, and then brought back to the body.
Surgery for Vascular access
Through the large strong vein to sustain high levels of flow rate, it is then fuse into an artery forming a fistula.
What is a synthetic tube?
Also known as a graft
What is dialysate?
Is dialysis fluid (solution of pure water, electrolytes and salts (bicarbonate and sodium)
Purpose of dialysate
To pull toxins from the blood into the dialysate, through a process called diffusion.
Concentration in the process
In the blood of the hemodialysis patient, there is a high concentration of waste, while the dialysate has a low concentrate of waste. Due to the difference in concentration, waste will be moved through the semipermeable membrane to create an equal amount on both sides.
Which has a higher concentration of waste? Blood or dialysate.
Blood
Hemodialysis is an effective treatment for which patient?
End stage renal patients
Will hemodialysis treatment alone will provide complete treatment? If so, why?
No, diet and fluid restrictions need to be followed, and medicines may need to be taken to replace other functions of kidneys, such as regulating blood pressure and stimulation production of RBC to prevent anemia.
