 Most common complication is
 Have client void pre-procedure PERITONITIS and shock
 Inform pt about bleeding (blood is heparinized)  First sign: cloudy dialysate return
 Monitor for signs of complications  Most common dialysate:
(BEDSSH) INFERSOL
 Bleeding  Infusion time: 10-20 minutes
 Embolism  Dwelling time: 30-45 minutes
 DISEQUILIBRIUM SYNDROME –
results from rapid loss of nitrogenous  What determines effectiveness of dialysis?
waste products particularly UREA from  Weight of patient
the brain
 HPN 7. Assist in surgical procedure: KIDNEY
 Disorientation – initial sign TRANSPLANTATION
 Nausea and vomiting
 anorexia
 Headache
 Paresthesia, peripheral
 Numbness
 Septicemia
 Shock
 Hepatitis
 Avoid BP taking, phlebotomy, IV meds at the
site of fistula, blood extraction to prevent
compression
 Maintain patency of shunt/fistula:
 Palpate for thrills, auscultate for bruits
 Instruct that minimal bleeding is expected
since blood is heparinized
 Avoid use vasodilators, sedatives, and
tranquilizers to prevent hypotension unless
ordered
 Prepare at bedside bulldog clips to prevent  Meds: steroids, immunosuppressants, anti
embolism lymphocyte globulin…
 Auscultate for bruits and palpate for thrills
(if (+)  patent)  Feared complication: rejection, characterized
by hypertension, headache, dizziness,
 PERITONEAL DIALYSIS decreased CBC
 2 TYPES OF REJECTION
 Acute – 6 to 10 months
 Chronic – 5-10 years
