BACKGROUND: Transesophageal echocardiography (TEE) is used in the emergency department to guide resuscitation during cardiac arrest. Insertion of a TEE transducer requires manual skill and experience, yet in some residency programs cardiac arrest is uncommon, so some physicians may lack the means to acquire the manual skills to perform TEE in clinical practice. For other infrequently performed procedural skills, simulation models are used. However, there is currently no model that adequately simulates TEE transducer insertion. The aim of this study is to evaluate the feasibility and efficacy of using a cadaveric model to teach TEE transducer placement among novice users. METHODS: A convenience sample of emergency medicine residents was enrolled during a procedure education session using cadavers as tissue models. A pre-session assessment was used to determine prior knowledge and confidence regarding TEE manipulation. Participants subsequently attended a didactic and hands-on education session on TEE placement. All participants practised placing the TEE transducer until they were able to pass a standardized assessment of technical skill (SATS). After the educational session, participants completed a post-session assessment. RESULTS: Twenty-five residents participated in the training session. Mean assessment of knowledge improved from 6.2/10 to 8.7/10 (95％ confidence interval [CI] of knowledge difference 1.6–3.2, P<0.001) and confidence improved from 1.6/5 to 3.1/5 (95％ CI of confidence difference 1.1–2.0, P<0.001). There was no relationship between training level and the delta in knowledge or confidence. CONCLUSIONS: In this pilot study, the use of a cadaveric model to teach TEE transducer placement methods among novice users is feasible and improves both TEE manipulation knowledge and confidence levels.
