Key result
A novel 3D-printed pericardiocentesis teaching model was rated as reasonably mimicking a pericardial effusion by 93% of residents using ultrasound guidance and 92% using a blind approach.
A novel 3D-printed pericardiocentesis model provides a low-cost, durable, and realistic training tool for emergency medicine residents.
Offers feasible low-cost pericardiocentesis simulator for EM training; leaves open impact on resident competence.
INTRODUCTION: Pericardiocentesis is a high-risk/low-frequency procedure important to emergency medicine (EM). However, due to case rarity it is not often performed on a patient during residency training. Because the coronavirus disease 2019 pandemic limited cadaver-based practice, we developed a novel, low-cost, low-fidelity pericardiocentesis model using three dimensional-printing technology to provide advances on prior home-made models. METHODS: Residents watched a 20-minute video about performing a pericardiocentesis and practiced both a blind and ultrasound-guided technique. We assessed model fidelity, convenience, and perceived provider competence via post-workshop questionnaire. RESULTS: A total of 24/26 (93%) individuals practicing on the ultrasound-guided model and 22/24 (92%) on the blind approach model agreed or strongly agreed that the models reasonably mimicked a pericardial effusion. CONCLUSION: Our low-cost, low-fidelity model is durable, mimics the clinical case, and is easy to use. It also addresses known limitations from prior low-fidelity models.

Lord et al. (2021) studied Pericardiocentesis training (n=26). 3D-printed pericardiocentesis teaching model was evaluated on Agreement that the models reasonably mimicked a pericardial effusion. A novel 3D-printed pericardiocentesis teaching model was rated as reasonably mimicking a pericardial effusion by 93% of residents using ultrasound guidance and 92% using a blind approach.
