1

what are indications for dialysis

AEIOU
acidosis
electrolyte imbalances - hyperkalaemia
intoxication - overdose
oedema
uraemia

2

what is continuous ambulatory peritoneal dialysis

peritoneum membrane is used as a filter
dialysis solution containing dextrose is pumped in to make a gradient and blood gets filtered
waste is removed

3

what are side effects of continuous and overnight ambulatory peritoneal dialysis

weight gain
thickening of membrane/sclerosis
infection
social and psychological effects

machine filters blood
need at least 4hrs a day, 3 days a week
blood is accessed from a fistula or tunnelled cuffed catheter
NEVER TAKE BLOOD FROM A FISTULA - IT IS ONLY FOR DIALYSIS

6

what can you inspect on a fistula site

aneurysms
skin integrity
palpable thrill
machinery murmur on auscultation

7

what are side effects of haemodialysis

steal syndrome if fistula

8

what is an indication for renal transplant

end stage renal disease - GFR less than 15
bicarbonate less than 10mmoles/l

9

how is the new kidney fitted in

in the suprapubic area
old kidneys are not removed
artery and vein are attached to external iliac artery and veins, ureter attached directly to bladder

10

how is rejection avoided

match kidney to patient by HLA types
life long immunosuppression - prednisolone, tacrolimus, mycophenolate

11

what investigations would you do in renal transplant

post op vascular scan to see if new kidney is well perfused
biopsy to look for any signs of rejection like immune cells
