Insights

Distal radial artery catheterization is safe for hemodialysis patients, showing a low rate of conventional radial artery occlusion and manageable complications. This approach offers a feasible option for cardiac procedures in this population.

Area of Science:

  • Cardiovascular Medicine
  • Interventional Cardiology
  • Nephrology

Background:

  • The distal radial artery (DRA) approach is emerging for cardiac catheterization.
  • Its safety and feasibility in hemodialysis (HD) patients remain uninvestigated.

Purpose of the Study:

  • To assess the incidence of conventional radial artery (CRA) occlusion after DRA puncture in HD patients.
  • To evaluate puncture site complications following DRA access in this cohort.

Main Methods:

  • Retrospective analysis of 117 HD patients undergoing cardiac catheterization via DRA (Sept 2017 - Dec 2019).
  • Primary endpoint: CRA occlusion via vascular ultrasonography.
  • Secondary endpoints: hemostasis difficulty, DRA occlusion, aneurysm, arteriovenous shunt, acute ischemia.

Main Results:

  • Successful DRA puncture in 90.5% (106/117) of patients.
  • CRA occlusion occurred in 3.5% (3/85) of patients evaluated.
  • DRA occlusion and aneurysm rates were 5.9% and 1.2%, respectively.

Conclusions:

  • Distal radial artery catheterization is feasible in hemodialysis patients.
  • The incidence of CRA occlusion and other complications is clinically acceptable.

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 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,...

Cardiac Catheterization I: Pre-Procedure Overview

Cardiac catheterization is an invasive diagnostic technique used to identify and evaluate structural and functional diseases of the heart and major blood vessels. This technique diagnoses congenital heart disease, coronary artery disease, valvular heart disease, and coronary spasms and assesses ventricular function. It helps guide treatment decisions, including the need for revascularization procedures like percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG) and...

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...

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...
