Comparison of Reusable Models in Pericardiocentesis Simulation Training

Area of Science:

• Medical Education
• Surgical Simulation
• Point-of-Care Ultrasound

Background:

• Pericardiocentesis is a critical, potentially life-saving procedure.
• Effective training is essential for proficiency in pericardiocentesis.
• Low-cost simulation models are needed to enhance procedural training.

Purpose of the Study:

• To compare the effectiveness of two low-cost pericardiocentesis training models: an agar-based model and the novel Centesys model.
• To evaluate ultrasound image quality, realism, learner confidence, and satisfaction.

Main Methods:

• A pilot randomized 2x2 crossover trial was conducted with 20 physicians.
• Participants trained with both agar-based and Centesys models.
• Confidence, realism, and satisfaction were rated on a 7-point Likert scale.

Main Results:

• Centesys significantly improved post-training confidence (median 5 vs. 2.5, P=0.007).
• Centesys demonstrated superior realism in cardiac anatomy simulation (median 5 vs. 3.5, P=0.002) and higher learner satisfaction (median 5 vs. 4, P<0.001).
• All participants successfully inserted a pericardial drain using the Centesys model.

Conclusions:

• The Centesys model is an effective tool for teaching ultrasound-guided pericardiocentesis and drain insertion.
• Centesys offers enhanced realism and learner satisfaction compared to the agar-based model.
• This simulation provides a valuable, low-cost training solution for a critical procedure.
