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.
