Summary
Therapeutic apheresis (TA) requires reliable vascular access, with choices depending on treatment duration. Arteriovenous fistulae (AVF) are preferred for chronic TA, but require specialized care planning.
Area of Science:
- Nephrology
- Vascular Surgery
Background:
- Therapeutic apheresis (TA) and hemodialysis (HD) rely on extracorporeal circuits and vascular access.
- TA utilizes lower blood flow rates (<100 mL/minute) compared to HD (approx. 400 mL/minute).
Observation:
- Vascular access choice for TA is determined by treatment duration and indication.
- Peripheral venous access suffices for short-term TA.
- Tunnelled catheters and arteriovenous fistulae (AVF) are suitable for long-term TA.
Findings:
- Arteriovenous fistulae (AVF) offer advantages for chronic TA, mirroring hemodialysis literature.
- Advance planning and specialized care are crucial for AVF used in TA.
- Healthcare providers need enhanced familiarity with AVF maintenance in TA contexts.
Implications:
- Optimizing vascular access selection can improve TA efficacy and patient outcomes.
- Standardized protocols for AVF care in TA are needed.
- Further research into AVF management for TA patients is warranted.

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,...
01:25Extracorporeal Removal of Drugs: Hemoperfusion and Hemofiltration
Hemoperfusion and hemofiltration are critical techniques in medical treatments to eliminate accumulated drugs, metabolites, and electrolytes from the bloodstream. These methods are particularly vital in cases of accidental poisoning and drug overdose.Hemoperfusion involves passing blood through an adsorbent material to remove unwanted substances. The main adsorbents used in hemoperfusion include activated charcoal and Amberlite resins. Activated charcoal can adsorb both polar and nonpolar...
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...
01:26Extracorporeal Removal of Drugs: Continuous Renal Replacement Therapy
Continuous Renal Replacement Therapy (CRRT) is an essential intervention for patients experiencing severe kidney dysfunction. This therapy offers a continuous mechanism for removing fluids and toxins from the bloodstream, leveraging the patient’s blood pressure to facilitate filtration through a specialized filter. This method contrasts with intermittent dialysis, providing a gentler and more consistent removal of waste products and excess fluid, which is particularly beneficial in critically...
01:29Venous Thrombosis III: Interprofessional Care
Venous thrombosis requires effective prevention and treatment strategies to improve patient outcomes and reduce potential complications.Prevention StrategiesHealthcare providers must prioritize preventing venous thromboembolism (VTE) for all adult patients upon admission. Interventions depend on bleeding and thrombosis risk, medical history, current medications, diagnoses, planned procedures, and patient preferences. Patients on bed rest should change positions every two hours and, if not...
