Study Notes
Acute Indications for Dialysis
- Initiating dialysis in acute kidney injury is prompted by severe symptoms such as oliguria, anuria, or fluid overload.
- Significant electrolyte abnormalities, such as hyperkalemia (high potassium), can also necessitate immediate dialysis.
Chronic Indications for Dialysis
- Renal replacement therapy (RRT) is commonly recommended to start when glomerular filtration rate (GFR) falls below 15 mL/min.
- Chronic complications of renal failure, including severe anemia or uremic symptoms, serve as grounds for initiating dialysis.
Goals of Dialysis
- One primary goal is to eliminate waste products and toxins, restoring fluid and electrolyte balance for those with renal failure.
Metabolic Acidosis and Dialysis
- Metabolic acidosis becomes a reason for dialysis when sodium bicarbonate therapy is ineffective or impractical due to the risk of fluid overload.
Early Dialysis in Diabetics
- Diabetics may require earlier initiation of dialysis, especially when facing frequent hospitalizations for complications related to kidney failure or metabolic control.
Electrolyte Abnormalities
- Hyperkalemia, an electrolyte imbalance that can lead to dangerous heart rhythm issues, is a key indicator for starting dialysis in acute kidney injury.
Uremic Complications
- Complications from uremia, such as pericarditis or severe pruritus, may indicate a need for immediate dialysis intervention in patients with acute kidney injury.
