Dialysis and Kidney transplants lecture Flashcards
In what groups of people is CKD most prevelant
- 60 yrs or older
- African Americans
- Native Americans
- More men than women
Most common causes of CKD
- Diabetes
- HTN
Risk factors for CKD
- Diabetes
- HTN
- HLD
- Smoking
- Recreational drugs
- NSAIDs
- Obesity
- Glomerulonephritis
- Lupus
- Atherosclerosis
Artificial process for removing waste and water from the body when the kidneys no longer function
Renal Replacement Therapies or RRT’s, dialysis
Name some RRT’s
- Hemodialysis (HD)
- Peritoneal Dialysis (PD)
- CRRT
Hemodialysis (HD) uses what?
an artifical membrane
Peritoneal dialysis (PD) uses what?
A Permanent Tenckhoff indwelling catheter
Continuous RRT is used to treat what?
- Short term for ARF unstable - fluid volume overload (oliguric phase)
- Does not produce rapid shifts like hemodialysis
VV
RRT
Venovenous
AV
RRT
Arteriovenus
Goals of dialysis
- Remove end-products of protein metabolism (Cr & BUN)
- Maintain and correct electrolyte levels (elevated potassium)
- Correct acidosis
- Remove excess fluids
Neuro changes such as lethargy, AMS, and cognitive changes can indicate what?
excess build up of urea
What kinds of patients require dialysis?
AKI or ESRD with the following:
* Severe F/E imbalances
* Elevated creatinine and/or potassium
* acidosis
* uremic symptoms
* patients with GFR less than 10mL/min
Types of access for HD
Central Venous Catheter
Fistula
Graft
What type of HD access is this
For short term use or until long term AV fistula or graft
Central venous catheter
What type of HD access is this
Created by surgery with the artery & vein anastomosed and requires maturation of weeks to months
Fistula
What type of HD access is this
Created by inserting a prosthetic graft between the artery and vein
Graft
What needs to be monitored/checked before a patient goes to dialysis and after they return?
- Vitals (BP)
- Weight
- HD Access site
What type of dialysis is this?
- usually 3 times a week
- Sessions last 3-5 hrs
- duration of sessions, and number of sessions per week change as pt’s status changes
- Can be done outpatient, in the hispital, or at home
Hemodialysis
Complications associated with HD
- Hypotension
- Muscle cramps
- Headaches
- N/V
- Dizziness
- Malaise
- Systemic infection is a concern
- Dialysis dementia
- Localized AV fistula/graft complication
A dialysis patient is complaining of Light-headedness, N/V, seizures, vision changes, and chest pain what do you suspect?
Hypotension
S/S of Hypotension
- Light-headedness
- N/V
- Seizures
- Vision changes
- Chest pain
If hypotension is suspected during HD what needs to be done
Fluid removal rate needs to be decreased and NS therapy needs to be added
If a patient recieving HD is experiencing
- muscle cramps
- headaches
- N/V
- dizziness
- malaise
What needs to be done?
Filtration rate needs to be slowed
or
NS Bolus
HD patients are at higher risk for what?
- Hep B
- Hep C
- HIV
What is this complication of HD
- Progressive, potentially fatal neurological complication from long-term dialysis
- May be d/t aluminium present in phosphate binders
Dialysis dementia
What is this called?
Happens d/t very rapid changes in the composition of the extracellular fluid (why first HD runs slower)
Disequilibrium syndrome
All of the following are S/S of what?
- N/V
- Confusion
- Restlessness
- Headaches
- Decreased LOC
- Twitching
- Jerking
- Seizures
Disequilibrium syndrome
