Lightly Embalmed Cadavers as a Training Tool for Ultrasound-Guided Procedures Commonly Used in Interventional...

Area of Science:

• Medical Education
• Interventional Radiology
• Ultrasound Imaging

Background:

• Mastering ultrasound (US) imaging and US-guided procedures is challenging for trainees.
• Current simulation models for US-guided procedures lack realism.
• Simulation training is crucial but limited by available phantom models.

Purpose of the Study:

• To evaluate the feasibility of using lightly embalmed cadavers for simulating interventional radiology (IR) procedures.
• To provide a realistic training alternative for medical students and residents in US-guided procedures.
• To enhance competency in common IR procedures prior to direct patient care.

Main Methods:

• Lightly embalmed cadavers were positioned in various patient postures (supine, prone, seated).
• Simulated common IR procedures including liver biopsy, kidney biopsy, thoracentesis, and vascular access using US guidance.
• Lidocaine injection and percutaneous techniques were employed to mimic real procedures.

Main Results:

• Cadavers allowed for full procedure simulation due to their positionability.
• Trainees successfully obtained arterial and venous vascular access, passed wires, and placed catheters.
• Realistic tissue texture provided valuable tactile feedback, and simulated images closely resembled those from living patients.

Conclusions:

• Lightly embalmed cadavers serve as an innovative and practical tool for simulating IR US-guided procedures.
• This method offers a realistic approach for deliberate practice before initial patient encounters.
• Cadaver simulation enhances trainee confidence and skill in US-guided interventions.
