Types of Dialysis Hemodialysis (HD): extracorporeal removal of waste products (urea, creatinine) and free water from the blood across semi- permeable membrane
Types of Dialysis Ultrafiltration (UF): -Way to remove extra fluid volume -Just know term exists CVVH: -Used mainly in ICU for patients who can’t tolerate intermittent dialysis -Less drastic fluid shifts and hypotension -Runs for 24 hours a day -Done through temporary catheter
Types of Dialysis Peritoneal Dialysis (PD): patient’s peritoneal membrane is dialyzer; can be done at home.
Access Fistula: Best choice since directly connects native artery to vein Can take up to 6 months to mature. Made by Vascular Surgery Graft: Synthetic tubing connects artery to vein Second best choice Also by Vascular Surgery More complications such as thrombosis, outlet obstructions, aneurysms
Access Catheters: Can be tunneled or temporary Usually into right internal jugular vein
Indications for Dialysis A (acidosis) E (electrolytes like high K) I (ingestions) O (overload) U (uremia)
