Advancements in renal replacement therapies improve outcomes for critically ill patients. Newer continuous renal replacement therapy (CRRT) techniques enhance efficiency and solute clearance, aiding in sepsis management.

Area of Science:

  • Nephrology
  • Critical Care Medicine
  • Biomaterials Science

Background:

  • Technological and biomaterial advancements drive progress in renal replacement therapies for acute, critically ill patients.
  • Continuous arteriovenous hemofiltration has evolved into various CRRT techniques, including continuous venovenous hemofiltration, hemodiafiltration, and high flux dialysis.

Purpose of the Study:

  • To review the evolution and clinical application of CRRT techniques in critically ill patients.
  • To highlight improvements in efficiency and solute clearance offered by modern CRRT.
  • To discuss the role of advanced CRRT in managing acute inflammation and sepsis.

Main Methods:

  • Review of historical development and current clinical use of CRRT techniques.
  • Analysis of efficiency metrics, such as urea daily clearances.

  • Discussion of recent observations regarding high-volume fluid exchange in hemofiltration.
  • Evaluation of the role of hardware and software in newer CRRT systems.

    • Main Results:

    • CRRT techniques have significantly improved efficiency, with urea daily clearances exceeding 50 L.
    • Highly permeable dialyzers enhance the clearance of larger solutes, crucial for removing inflammatory mediators.
    • High-volume fluid exchange in hemofiltration shows promise for managing sepsis and acute inflammation.
    • Modern CRRT systems offer enhanced capabilities for safe and effective treatment.

    Conclusions:

    • Continuous renal replacement therapy has evolved significantly, offering improved efficiency and broader solute removal capabilities.
    • Advanced CRRT techniques, supported by sophisticated hardware and software, are vital for managing complex conditions like sepsis in critically ill patients.
    • Further research into high-volume fluid exchange strategies within CRRT is warranted.
