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...

Cardiac Catheterization IV: Nursing Management

Nursing responsibilities before cardiac catheterization include:Assess for allergies and establish baseline health status.Before cardiac catheterization, assess the patient for allergies to contrast dye. Perform a comprehensive baseline assessment, including vital signs, heart and breath sounds, and a neurovascular assessment of the extremities, noting distal pulses, skin color, and temperature. Instruct the patient to fast for 8-12 hours before the procedure. Evaluate baseline laboratory...
Varicose Veins II: Diagnostic Studies and Interprofessional Care01:26

Varicose Veins II: Diagnostic Studies and Interprofessional Care

Varicose veins, or varicosities, develop when the valves in the veins, which control blood flow, weaken or damage. It causes blood to pool and the veins to enlarge. Understanding the clinical manifestations, diagnostic approaches, and management options for varicose veins is crucial for effective treatment and relief.Clinical manifestationsClinical manifestations of varicose veins include a heavy, achy feeling or pain after prolonged standing or sitting. This discomfort can often be relieved by...

Peripheral Artery Disease V: Postoperative Nursing Management

During the postoperative period, it is crucial to focus on maintaining circulation, identifying and managing potential complications, and planning for discharge.Nursing AssessmentVital signs monitoring: Regularly monitor vital signs, including blood pressure, heart rate, respiratory rate, and temperature, to detect early signs of complications such as bleeding and infection.Circulation assessment: Monitor pulses, perform Doppler assessments, and check capillary refill, color, temperature, and...
Endocarditis IV: Nursing Management01:29

Endocarditis IV: Nursing Management

Infective endocarditis (IE) is a chronic infection of the heart's endocardium, primarily affecting the heart valves. A detailed nursing assessment for a patient with IE involves collecting subjective and objective data to ensure an accurate diagnosis and timely intervention.Subjective DataThe nurse gathers information about the patient's symptoms and complaints during the subjective assessment. Patients with infective endocarditis often report non-specific symptoms that can mimic other...

Summary

Routine surveillance of hemodialysis vascular access may not improve outcomes. Current evidence suggests that not all accesses benefit from routine screening and intervention, questioning its widespread recommendation.

Area of Science:

  • Nephrology
  • Vascular Surgery

Background:

  • Hemodialysis vascular access surveillance is common but debated.
  • Screening tests like access blood flow and dialysis venous pressure are frequently used.

Purpose of the Study:

  • To review limitations in current hemodialysis vascular access surveillance strategies.
  • To evaluate the evidence supporting surveillance in prolonging access patency and survival.

Main Methods:

  • Review of existing literature and randomized controlled trials on vascular access surveillance.
  • Analysis of the four components of surveillance strategies: condition, screening, intervention, and outcomes.

Main Results:

  • Randomized controlled trials have not consistently demonstrated improved outcomes for grafts with surveillance.
  • Limited evidence suggests surveillance may not prolong the life of native fistulae without intervention.

Conclusions:

  • Current evidence does not support routine surveillance and intervention for all hemodialysis vascular accesses.
  • Limitations within surveillance components may hinder desired outcomes, necessitating a re-evaluation of current practices.
