Hemodialysis treatment time: a fresh perspective
Clinical Journal of the American Society of Nephrology : CJASN
|September 3, 2011
Summary
Shorter hemodialysis treatments, while reducing patient burden, may increase risks. A minimum adequate dialysis time of 4 hours is recommended for most patients, making shorter sessions the exception.
Area of Science:
- Nephrology
- Clinical Medicine
- Dialysis Therapy
Background:
- Historical shifts in hemodialysis practices have favored shorter treatment durations.
- Reduced dialysis time was pursued to alleviate patient burden and improve efficiency.
- Concerns exist regarding potential negative impacts of shortened dialysis on patient outcomes.
Purpose of the Study:
- To review the evolution of hemodialysis treatment times.
- To analyze the relationship between dialysis dose, frequency, and patient outcomes.
- To propose an updated treatment paradigm for hemodialysis duration.
Main Methods:
- Literature review examining historical, clinical, and economic factors influencing dialysis duration.
- Analysis of recent studies on the link between dialysis dose and patient morbidity/mortality.
- Consideration of dialysis frequency in relation to treatment time.
Main Results:
- Shorter hemodialysis treatments present a trade-off between reduced burden and potential increased risks.
- Understanding the complex interplay between dialysis dose and outcomes has improved.
- Dialysis frequency plays a role alongside treatment duration.
Conclusions:
- A minimum adequate hemodialysis treatment time of 4 hours should be considered for most patients.
- Treatments shorter than 4 hours should become the exception, not the standard.
- A revised treatment paradigm is needed to optimize hemodialysis protocols.

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,...
01:25Hemodialysis 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...
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...
01:30Extracorporeal 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...
