Abstract
|
|
|
Objective: Cardiac tamponade with hemodynamic collapse requires immediate treatment, and ultrasound-guided pericardiocentesis is the treatment of choice. Although an essential skill for emergency physicians, there is a lack of training.
We created a phantom that could practice ultrasound-guided pericardiocentesis using readily available materials. The pros and cons of the materials used were then compared.
Methods: Cardiac tamponade phantoms were made from gelatin, and included a heart, liver, and rib cage. We conducted a model-specific satisfaction questionnaire targeting 15 emergency physicians. The questionnaire was designed to be answered on a Likert 5-point scale.
Results: Creating the gelatin model took 6 hours. At room temperature, the gelatin model was able to retain its shape for 3 days. Fifteen physicians participated in the questionnaire, comprising five subjects having actual pericardiocentesis experience. In the questionnaire, our model achieved high satisfaction with all questions.
Conclusion: In our study, the pericardiocentesis phantom made from gelatin could maintain its shape for a long time, there was better recognition of the needle tip, and the model was more similar to the actual cardiac tamponade situation.
Considering these positive characteristics, we recommend the phantom as a model for pericardiocentesis training.
