Study Notes
Overview of Hemodialysis
Hemodialysis is a type of renal replacement therapy used to treat end-stage renal disease (ESRD). It involves removing waste products from the blood when the kidneys are no longer able to do so.
How Hemodialysis Works
- Blood is pumped out of the body through a surgically created access (e.g., arteriovenous fistula or graft)
- The blood then passes through a dialyzer, a special filter that removes waste products and excess fluids
- The cleaned blood is then returned to the body
Types of Hemodialysis
- In-center hemodialysis: performed at a dialysis center, typically 3 times a week
- Home hemodialysis: performed at home, often with the assistance of a care partner
- Nocturnal hemodialysis: longer, slower dialysis sessions performed at night while sleeping
Components of the Hemodialysis Machine
- Dialyzer: filters waste products from the blood
- Pumps: control blood flow and fluid removal
- Sensors: monitor blood flow, pressure, and fluid removal
- Fluid management system: controls the concentration of the dialysate (dialysis fluid)
Complications and Side Effects
- Low blood pressure: due to excess fluid removal
- Muscle cramps: caused by fluid and electrolyte shifts
- Fatigue: common side effect of hemodialysis
- Infection: risk of infection at the access site
Benefits and Goals
- Remove waste products: such as urea, creatinine, and other toxins
- Regulate electrolyte levels: maintain healthy levels of electrolytes like potassium and sodium
- Control fluid balance: remove excess fluids and regulate blood pressure
- Improve quality of life: alleviate symptoms of ESRD and improve overall health
