Dialysis01:15

Dialysis

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...

Dialysis

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...

Extracorporeal 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...
Hemodialysis I: Introduction01:25

Hemodialysis 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...

Hemodialysis 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,...
Hemodialysis III: Nursing Management01:25

Hemodialysis 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...

Summary
This summary is machine-generated.

The number of Brazilians on dialysis continues to rise, with increasing rates of complications like anemia and poor vascular access. This highlights an urgent need for improved chronic kidney disease patient care strategies.

Area of Science:

  • Nephrology
  • Epidemiology
  • Public Health

Background:

  • The annual Brazilian Dialysis Survey (BDS) is crucial for informing national health policies.
  • The Brazilian Society of Nephrology (BSN) conducts this vital survey.

Purpose of the Study:

  • To report the 2024 epidemiological findings from the Brazilian Dialysis Survey.
  • To compare current dialysis statistics with previous years.

Main Methods:

  • A voluntary online survey was distributed to Brazilian chronic dialysis centers.
  • A nationally representative random sample of 258 dialysis centers was used for prevalence and incidence estimates.
  • Data collected included patient characteristics, center attributes, and treatment modalities.

Main Results:

  • An estimated 172,585 patients were on dialysis in Brazil as of July 1st, 2024.
  • Prevalence and incidence rates were 812 and 249 per million population, respectively.
  • Trends showed increased catheter use, higher rates of anemia, hyperphosphatemia, hyperkalemia, and lower dialysis adequacy (Kt/V), with a 16.5% crude annual mortality rate.

Conclusions:

  • The number and prevalence of chronic dialysis patients in Brazil continue to increase.
  • Deteriorating trends in vascular access, dialysis adequacy, and metabolic control necessitate focused improvements in patient care.
