Dialysis Flashcards
7 serious causes of hypotension during dialysis to consider (rather than just transient needing a small fluid bolus)
Tamponade Anaphylaxis MI Hyperkalemia Air embolism Infection Bleeding
Three mechanisms of dialysis related bleeding
Underlying platelet dysfunction
HD related transient thrombocytopenia
Anticoagulation
Treatment of bleeding in dialysis patient
DDAVP, cryo, estrogen, transfusion
Protamine to reverse heparin if overanticoagulated
What is dialysis disequilibrium syndrome and how is it managed
Cerebral edema due to rapidly changing body fluid composition and osmolality, presents as headache, n/v, muscle cramping usually during or right after HD. Severe will have altered mental status, seizures, coma
Treatment is supportive, usually resolves in a few hours.
No role for hyperosmolar therapy
Treatment of fistula puncture site bleeding
Pressure, not occlusion
Can use gel foam soaked in thrombin, tissue adhesive
What is branham sign
Drop in HR with temporary occlusion of HD access site, signals high output heart failure
Most common organisms in vascular access site infection
Staph and strep. Can also see gram negative
Treatment vascular access site infection
Blood cultures, culture access site
Vanco and ceftriaxone or gentamycin for GN
Bugs seen in peritoneal dialysis related peritonitis
Staph, strep, GN, rarely anaerobes and fungi, suspect perforation if multiple organisms grow
Clinical presentation of PD associated peritonitis
Fever, abdo pain, cloudy PD fluid
Cut off of >100 WBC or 50% neutrophils (lower than the 250 WBC cut off for SBP)
Treatment of HD associated PD
Intraperitoneal antibiotics, vanco and ceftriaxone
