Dialysis adequacy today: a European perspective
Summary
Improving haemodialysis (HD) involves enhancing blood toxin clearance and managing metabolic disorders. High-volume convective therapies like online-haemodiafiltration (OL-HDF) show promise but require more trial evidence for widespread adoption.
Area of Science:
- Nephrology and Dialysis Technology
- Cardiovascular Health in Chronic Kidney Disease
- Uremic Toxin Clearance Mechanisms
Background:
- Dialysis patients face high mortality, necessitating improvements in haemodialysis (HD) and treatment strategies.
- Optimizing dialysis for the growing end-stage chronic kidney disease (CKD-5D) population requires re-evaluating current practices for patient well-being.
- Efficient removal of uremic toxins, fluid, and salt, alongside correction of metabolic disorders (anemia, mineral bone disease), are key objectives.
Discussion:
- High-flux membranes are crucial for eliminating small and large uremic toxins.
- Convective therapies, such as online-haemodiafiltration (OL-HDF), augment the efficacy of high-flux HD (HF-HD).
- Despite over two decades of clinical use, widespread adoption of convective modalities is limited by the need for more conclusive evidence from large-scale randomized controlled trials.
Key Insights:
- High-flux membranes and convective therapies enhance toxin removal in dialysis.
- OL-HDF offers superior detoxification compared to standard HF-HD.
- Further evidence from prospective randomized controlled trials is needed to support broader implementation of convective therapies.
Outlook:
- A European perspective advocates for optimal dialysis strategies, including high convective therapies.
- Overcoming inertia in adopting advanced dialysis practices may significantly improve patient well-being and survival.
- Future research should focus on large-scale trials to validate the benefits of convective therapies.

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...
01:25Hemodialysis 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,...
01:30Extracorporeal Removal of Drugs: Peritoneal Dialysis and Hemodialysis
Patients with end-stage renal disease (ESRD) or those experiencing drug overdose often require extracorporeal methods to eliminate accumulated drugs and metabolites. Hemoperfusion, hemofiltration, and dialysis are the primary techniques to rapidly remove harmful substances without disrupting the patient's fluid and electrolyte balance. For those with compromised renal function, dosage adjustments of concurrent medications may be necessary during extracorporeal drug removal.Dialysis is a process...
01:25Hemodialysis III: Nursing Management
The nursing management of a patient undergoing hemodialysis includes several critical steps, starting with a thorough assessment before the procedure.Before the Hemodialysis ProcedureFirst, record the patient's vital signs—blood pressure, heart rate, respiratory rate, and temperature—to establish a baseline. This baseline is essential for detecting conditions such as hypotension that could impact the patient's response to dialysis. Document the patient's pre-dialysis weight, as this measurement...
