Abstract

Objectives This study aimed to introduce an easily made chicken breast simulator for ultrasound (US)-guided vascular access, foreign body (FB) detection, and hydrodissection in pediatric patients and to validate the effectiveness for training using this phantom tissue model. Methods The authors made the tissue phantom simulator using a chicken breast and rubber tourniquet for vascular access and fragments of a tongue blade and steel clip for FB detection and hydrodissection using a very simple method. We provided training on US-guided vascular access (following the tip [FTT] method), FB detection, and hydrodissection using this model for novice physicians to learn US-guided procedures for pediatric patients. In addition, we provided a questionnaire to solicit their thoughts on their knowledge and confidence to perform these procedures before and after training and to learn their thoughts on the similarity to actual patients and usefulness of this model on a 10-point Likert scale. Results A total of 16 emergency residents participated in this study. We obtained US images during vascular access (FTT) and FB detection/ hydrodissection procedures using this phantom tissue model. Residents' knowledge of and confidence to perform US-guided FTT method and FB detection/hydrodissection procedures after training increased to a statistically significant degree (P < 0.001 in all items). The median Likert scores regarding the similarity to actual patients and usefulness of this model were 8.5 (interquartile range, 7.5-9) and 10 (interquartile range, 8-10), respectively. Conclusions The model for US-guided procedures used in this study can be constructed by simple and easy methods, presents realistic procedural images, and was useful for training novice physicians to conduct US-guided procedures on pediatric patients.
