Biocompatible hemodialysis membranes for acute renal failure
The Cochrane Database of Systematic Reviews
|February 7, 2008
Summary
Biocompatible membranes (BCM) do not offer a survival or renal function recovery advantage over bioincompatible membranes (BICM) for acute renal failure (ARF) patients undergoing intermittent hemodialysis. This meta-analysis found no statistically significant differences in mortality or kidney function recovery between membrane types.
Area of Science:
- Nephrology
- Renal Medicine
- Dialysis Technology
Background:
- Acute renal failure (ARF) presents significant morbidity and mortality risks.
- Previous studies suggested a survival benefit with biocompatible membranes (BCM) versus bioincompatible membranes (BICM), but findings were inconsistent.
Purpose of the Study:
- To determine if BCM offer improved survival or renal function recovery compared to BICM in adult ARF patients requiring intermittent hemodialysis.
Main Methods:
- Conducted a meta-analysis of randomized and quasi-randomized controlled trials comparing BCM and BICM in ARF patients.
- Included 10 studies with 1100 patients for mortality analysis and 9 studies with 1038 patients for renal function recovery analysis.
- Classified cellulose-derived membranes as BICM and synthetic dialyzers as BCM, analyzing outcomes by dialyzer flux properties.
Main Results:
- No statistically significant difference in all-cause mortality between BCM and BICM (pooled RR 0.93; 95% CI 0.81 to 1.07).
- No significant difference in renal function recovery (pooled RR 1.09; 95% CI 0.90 to 1.31).
- Analysis by dialyzer flux properties also showed no significant differences in mortality or renal function recovery.
Conclusions:
- The use of biocompatible membranes (BCM) versus bioincompatible membranes (BICM) provides no demonstrable clinical advantage for patients with ARF requiring intermittent hemodialysis.

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...
01:24Hemodialysis II: Procedure and Complications
DialyzersA hemodialysis (HD) dialyzer is a plastic cartridge containing thousands of parallel hollow fibers, which serve as semipermeable membranes. These fibers are typically made from cellulose-based or other synthetic materials. During HD, blood is pumped into the top of the cartridge and distributed among these fibers. Simultaneously, dialysis fluid, known as dialysate, is introduced into the bottom of the cartridge, bathing the outside of the fibers. Across the semipermeable membrane,...
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...

01:15Dialysis
Dialysis is a diffusion-based purification process that separates analyte molecules from a complex matrix. This is accomplished by allowing molecules in the solution to pass through a semipermeable membrane into a liquid on the other side. The membrane is usually made of cellulose acetate or cellulose nitrate, and the second liquid must be miscible with the solution. Ions (e.g., chloride or sodium) or organic molecules (e.g., glucose) can pass through the membrane pores, which generally have...
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...
01:20Acute 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...
