Hemodialysis II: Procedure and Complications01:24

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 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 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...

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...
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...
Extracorporeal Removal of Drugs: Peritoneal Dialysis and Hemodialysis01:30

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...

Area of Science:

  • Cardiology
  • Nephrology
  • Medical Technology

Background:

  • Sudden cardiac death risk stratification in hemodialysis patients is a critical unmet need.
  • Non-invasive electrophysiological testing is difficult due to fluctuating patient status during hemodialysis.
  • Continuous electrocardiographic monitoring during hemodialysis may offer reproducible repolarization insights.

Purpose of the Study:

  • To assess the reproducibility of repolarization profiles using continuous electrocardiography during hemodialysis.
  • To explore the relationship between intradialytic ECG changes and serum electrolytes/parathyroid hormone.
  • To evaluate the potential of intradialytic ECG for sudden cardiac death risk stratification in hemodialysis patients.

Main Methods:

  • Continuous 12-lead digital ECGs were recorded five times at two-week intervals in stable hemodialysis patients.
  • Repolarization descriptors including QRS-to-T angle, PCA ratio, and TMD were calculated.
  • Serum electrolytes and parathyroid hormone levels were measured before monitoring.

Main Results:

  • 319 ECG recordings from 76 patients showed intra-subject reproducibility of repolarization descriptors.
  • PCA ratio and TMD increased during dialysis, correlating with heart rate changes.
  • Intradialytic changes in QRS-to-T angle correlated positively with parathyroid hormone levels.

Conclusions:

  • Repolarization descriptors exhibit dynamic, subject-specific profiles during hemodialysis.
  • Parathyroid hormone plays a role in the dynamics of myocardial repolarization.
  • Prospective evaluation of continuous intradialytic ECGs for risk stratification is warranted.
