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)
