Advantages & Disadvantages of CRRT

?

Advantages of using CRRT

• Suitable for use in hemodynamically unstable patients.
• Precise volume control, which is immediately adaptable to changing circumstances.
• Very effective control of uremia, hypophosphatemia and hyperkalemia.
• Rapid control of metabolic acidosis
• Improved nutritional support (full protein diet).
• Available 24 hours a day with minimal training.
• Safer for patients with brain injuries and cardiovascular disorders (particularly diuretic resistant CCF).
• May have an effect as an adjuvant therapy in sepsis.
• Probable advantage in terms of renal recovery.

  Disadvantages of using CRRT

  • Expense – probably the same as IHD.
  • Anticoagulation – to prevent extracorporeal circuit from clotting.
  • Complications of line insertion and sepsis.
  • Risk of line disconnection.
  • Hypothermia.
  • Severe depletion of electrolytes – particularly K+ and PO4, where care is not taken.
