Drug Accumulation During Multiple Dosing: Intermittent IV Infusions01:24

Drug Accumulation During Multiple Dosing: Intermittent IV Infusions

240
Intermittent intravenous (IV) infusion is a method of drug administration where medications are delivered over short infusion periods followed by intervals of no drug delivery. This approach helps to prevent sustained high drug concentrations in the bloodstream, reducing the risk of adverse effects associated with prolonged exposure. Unlike continuous infusion, steady-state concentrations may not be achieved during a single dosing cycle but can be reached through repeated...

Extracorporeal Removal of Drugs: Peritoneal Dialysis and Hemodialysis

475
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 III: Nursing Management

823
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...

Hemodialysis II: Procedure and Complications

755
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 I: Introduction

1.6K
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...

Tonicity in Animals00:59

Tonicity in Animals

123.4K
The tonicity of a solution determines if a cell gains or loses water in that solution. The tonicity depends on the permeability of the cell membrane for different solutes and the concentration of nonpenetrating solutes in the solution within and outside of the cell. If a semipermeable membrane hinders the passage of some solutes but allows water to follow its concentration gradient, water moves from the side with low osmolarity (i.e., less solute) to the side with higher osmolarity (i.e.,...

Summary

Hemodialysis uses an artificial kidney (dialyzer) to cleanse blood by removing waste products and excess fluid. This life-saving treatment is vital for patients with acute and chronic kidney injury.

Area of Science:

  • Nephrology
  • Biomedical Engineering

Background:

  • Hemodialysis is a critical medical treatment for kidney failure.
  • It involves using an artificial kidney (dialyzer) to filter blood.
  • Distinguishing hemodialysis from peritoneal dialysis is essential.

Purpose of the Study:

  • To provide an overview of intermittent hemodialysis.
  • To explain the mechanism of blood cleansing in hemodialysis.
  • To highlight its application in acute and chronic kidney injury.

Main Methods:

  • Blood is passed through an extracorporeal dialyzer.
  • A semipermeable membrane facilitates the removal of waste products.
  • Intermittent hemodialysis is the focus, contrasting with continuous renal replacement therapy.

Main Results:

  • Hemodialysis effectively removes blood urea nitrogen, creatinine, electrolytes, and toxins.
  • Excess fluid is also removed from the bloodstream.
  • The dialyzer's semipermeable membrane is key to the purification process.

Conclusions:

  • Intermittent hemodialysis is a cornerstone therapy for kidney injury.
  • The dialyzer's role in blood purification is central to its efficacy.
  • Understanding hemodialysis is crucial for managing renal conditions.
