Insights

Central venous catheters (CVCs) are crucial for hemodialysis but often malfunction. Salvage procedures like stripping and re-canalization offer effective solutions for CVC issues, improving patient access.

Area of Science:

  • Nephrology
  • Vascular Surgery

Context:

  • Hemodialysis patients face challenges with vascular access due to age and cardiovascular disease.
  • Central venous catheters (CVCs) are frequently used but prone to malfunction (87% of cases).

Purpose:

  • To review salvage procedures for malfunctioning central venous catheters (CVCs) in hemodialysis.
  • To evaluate the efficacy and complication rates of stripping and re-canalization techniques.
  • To explore alternative vascular access sites.

Summary:

  • Stripping removes fibrin strands around CVCs with 75-90% success.
  • Re-vascularization techniques achieve 100% success in placing CVCs across thrombosed vessels.
  • Alternative access sites include external jugular, femoral, and translumbar veins.

Impact:

  • Improved management of CVC malfunction in hemodialysis patients.
  • Enhanced vascular access strategies for challenging patient populations.
  • Potential reduction in CVC-related complications and need for replacement.

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...

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...

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,...
