Cardiac Catheterization I: Pre-Procedure Overview01:28

Cardiac Catheterization I: Pre-Procedure Overview

821
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...

Cardiac Catheterization IV: Nursing Management

538
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...

Area of Science:

  • Neurosurgery
  • Medical Education
  • Biomedical Engineering

Background:

  • External ventricular drain (EVD) placement is a fundamental neurosurgical procedure requiring proficient training.
  • Current training methods like cadaveric models and virtual reality simulations face barriers such as authenticity and cost.
  • There is a need for accessible, realistic, and cost-effective simulation tools for EVD placement training.

Purpose of the Study:

  • To develop and evaluate a novel, inexpensive, and anatomically accurate gelatin brain model for practicing external ventricular drain (EVD) placement.
  • To assess the usability, practicality, and effectiveness of this homemade model for neurosurgical resident training.

Main Methods:

  • A cost-effective brain model was created using ballistics gelatin, an anatomical skull mold, and a 3D-printed ventricular system.
  • Ten medical students received basic EVD placement training and then practiced using the gelatin brain model.
  • Student performance in EVD placement accuracy and their feedback on the model's usability were assessed.

Main Results:

  • The gelatin brain model is inexpensive (under $5), easy to create, and possesses appropriate firmness for catheter insertion.
  • All participating medical students found the model easy to use and beneficial for understanding EVD placement techniques.
  • 100% of students achieved adequate catheter tip positioning in the ipsilateral frontal horn on their first attempt.

Conclusions:

  • The developed gelatin brain model offers a replicable, affordable, and anatomically accurate simulation for practicing ventricular catheter placement.
  • This risk-free training environment can significantly enhance the learning curve for neurosurgeons and residents.
  • The model addresses accessibility issues, providing a viable alternative to expensive simulation technologies.
