Summary
Continuous renal replacement therapies have evolved significantly, offering safer and more versatile treatments for critically ill patients beyond acute renal failure. These advanced techniques are increasingly used for conditions like sepsis and liver failure.
Area of Science:
- Nephrology
- Critical Care Medicine
- Biomedical Engineering
Background:
- Traditional hemodialysis presents side effects and limitations, especially for unstable critically ill patients.
- The development of continuous renal replacement therapies (CRRT) marked a significant advancement.
- Advances in intensive care units (ICUs) enabled CRRT implementation without specialized dialysis facilities.
Purpose of the Study:
- To review the technological evolution of renal replacement therapies.
- To highlight the progression from early continuous techniques to modern CRRT.
- To explore the expanding applications of extracorporeal therapies in critical care.
Main Methods:
- Review of articles and published reviews on renal replacement therapies.
- Analysis of the historical development and technological advancements in the field.
Main Results:
- Continuous arterio-venous haemofiltration (CAVH) was the first continuous technique, improving safety and stability for critically ill patients.
- CRRT is now a standard treatment for acute renal failure in ICUs.
- Extracorporeal therapies are increasingly used for diverse conditions including sepsis, liver failure, and intoxications.
Conclusions:
- Technological progress has enhanced the functionality and ease of use of renal replacement therapies.
- These therapies offer improved safety profiles compared to traditional extracorporeal methods.
- Further advancements may establish CRRT as a routine component of critical care management.

01:27Dialysis
Renal failure occurs when the kidneys lose their ability to filter waste products from the blood effectively. It can be classified into two types: acute renal failure (ARF) and chronic renal failure (CRF).
Acute kidney injury develops suddenly and can be caused by pre-renal causes (e.g., hypovolemia, shock), intrinsic renal causes (e.g., acute tubular necrosis), or post-renal causes (e.g., urinary obstruction). In contrast, chronic renal failure progresses gradually over time and is often...

01:26Extracorporeal Removal of Drugs: Continuous Renal Replacement Therapy
Continuous Renal Replacement Therapy (CRRT) is an essential intervention for patients experiencing severe kidney dysfunction. This therapy offers a continuous mechanism for removing fluids and toxins from the bloodstream, leveraging the patient’s blood pressure to facilitate filtration through a specialized filter. This method contrasts with intermittent dialysis, providing a gentler and more consistent removal of waste products and excess fluid, which is particularly beneficial in critically...

Peritoneal dialysis (PD) is a medical process that removes waste products and excess fluid from the body using the peritoneal membrane as a natural filter.Peritoneal Dialysis MethodsSeveral methods can be used for peritoneal dialysis, including Acute Intermittent Peritoneal Dialysis, Continuous Ambulatory Peritoneal Dialysis, and Automated Peritoneal Dialysis, also known as Continuous Cyclic Peritoneal Dialysis.Acute Intermittent Peritoneal Dialysis (AIPD) is used for patients with uremic...
01:30Continuous Renal Replacement Therapy
Continuous Renal Replacement Therapy, also known as CRRT, is a procedural treatment for acute kidney injury (AKI) that gradually removes uremic toxins and fluids while maintaining acid-base balance and stabilizing electrolytes. It is particularly useful for hemodynamically unstable patients. Unlike intermittent hemodialysis, which is faster, CRRT provides a gentler approach over 24 hours, closely mimicking the function of natural kidneys. However, CRRT is not ideal for patients with...
01:25Hemodialysis I: Introduction
Hemodialysis (HD) is a medical treatment that artificially removes waste products, excess fluids, and toxins from the blood when the kidneys are no longer able to perform these functions effectively. In this process, blood is filtered through a semipermeable membrane, allowing for the selective removal of waste while preserving necessary components like blood cells and proteins. Hemodialysis is typically performed in patients with end-stage renal disease (ESRD) or severe kidney...
01:20Acute Kidney Injury V: Interprofessional Care
Acute Kidney Injury (AKI) requires a collaborative healthcare approach to restore renal function and prevent complications. Essential management strategies involve monitoring fluid and electrolyte balance, adjusting medications, initiating dialysis when necessary, and providing nutritional support.Fluid and Electrolyte ManagementFluid Monitoring: Regularly monitoring body weight, central venous pressure, and urine output helps detect fluid imbalances early. Patient intake and output are...
