    Study Notes

    Dialysis

    • Dialysis is a medical procedure that removes waste products, excess fluid, and toxins from the blood when the kidneys can no longer function properly
    • It's a life-saving treatment for severe kidney failure (acute or chronic) or end-stage renal disease (ESRD)

    Types of Dialysis

    1. Hemodialysis

    • Definition: Filters waste, salts, and fluid from blood using a dialyzer (artificial kidney) and a machine
    • Procedure: Blood is drawn, circulated through a machine with a filter (dialyzer), and returned to the body. The dialyzer has two parts: one for blood and one for dialysate (cleansing fluid). Waste products pass from blood to dialysate, which is discarded.
    • Duration and Frequency: Typically done 3 times per week, with each session lasting about 4 hours
    • Locations: In-center (clinic) or home hemodialysis
    • Peritoneal Dialysis (PD)
    • Definition: Uses the lining of the abdomen (peritoneum) as a natural filter
    • Procedure: Sterile solution (dialysate) is introduced into the abdominal cavity. The peritoneum acts as a filter, allowing waste and excess fluid to pass from blood into the dialysate, which is then drained and replaced.
    • Types: Continuous Ambulatory Peritoneal Dialysis (CAPD) - Manual exchanges 4-6 hours daily; Automated Peritoneal Dialysis (APD) - Machine exchanges dialysate automatically, usually overnight

    Hemodialysis Machine Components

    • Dialyzer (Artificial Kidney): Main component where blood filtration occurs, consisting of thousands of tiny fibers
    • Dialysate: Fluid that pulls waste and excess fluid from blood
    • Blood Pump: Circulates blood through the dialyzer
    • Heparin Pump: Administers heparin (blood thinner) to prevent clotting
    • Monitors and Alarms: Continuously monitor blood pressure, flow rate, and dialysate flow
    • Temperature Control: Regulates dialysate temperature for patient comfort
    • Ultrafiltration Control: Allows precise control of fluid removal to avoid complications

    Steps in Hemodialysis Treatment

    • Vascular Access: Establishes access to the patient's blood - fistula or graft or catheter.
    • Blood Filtration: Blood flows through the dialyzer, waste products removed
    • Return of Clean Blood: Clean blood returned via vascular access to the body
    • Continuous Monitoring: Machine monitors and adjusts settings to ensure patient safety

    Peritoneal Dialysis System Components

    • Peritoneal Catheter: Tube for introducing and draining dialysate into abdominal cavity
    • Dialysate Bags: Sterile bags of dialysate solution
    • Cycler (for APD): Machine that automatically infuses and drains dialysate

    Advantages and Disadvantages

    • Hemodialysis: Efficient waste removal but more time-consuming and requires vascular access
    • Peritoneal Dialysis: More independence but slower waste removal, and risk of infection (peritonitis)
