Summary
Continuous renal replacement therapy (CRRT) is evolving from a last-resort treatment for acute renal failure to a widely used blood purification method. Surgeons should understand CRRT for managing critically ill patients and exploring its anti-inflammatory benefits.
Area of Science:
- Nephrology
- Critical Care Medicine
- Surgical Intensive Care
Background:
- Historically, surgeons managed acute renal failure in ICU patients via nephrology consultation.
- The introduction of continuous renal replacement therapy (CRRT) has significantly changed this paradigm.
- CRRT was initially for hemodynamically unstable patients but is now widely adopted.
Purpose of the Study:
- To highlight the evolution and increasing importance of CRRT in critical care.
- To discuss the expanding applications of CRRT beyond renal replacement.
- To inform surgeons about advancements in extracorporeal therapies.
Main Methods:
- Review of the evolution and adoption of CRRT in critical care settings.
- Discussion of emerging research on blood purification and immunomodulatory effects.
- Exploration of CRRT's potential use in septic shock and operating rooms.
Main Results:
- CRRT is the dominant renal support in Australia and increasingly in Europe and the US.
- CRRT has spurred interest in broader blood purification techniques.
- Preliminary data suggest beneficial immunomodulatory effects of blood purification therapies.
Conclusions:
- CRRT represents a major advancement in managing acute renal failure in critically ill patients.
- Blood purification therapies, including CRRT, show potential for immunomodulation and adjunctive treatment for conditions like septic shock.
- Surgeons must be aware of these extracorporeal therapy developments to optimize care for critically ill patients.
