| Summary: | Abstract Introduction Acute button battery ingestion is an uncommon but life-threatening ingestion. This case was developed to review and teach PGY1-PGY3 emergency medicine residents and pediatric emergency medicine fellows aspects critical to the evaluation and recognition of a button battery lodged in the esophagus based on radiographic characteristics, and to know the importance of immediate removal. Methods This case contains four elements to help run the simulation: (1) a case narrative, which includes all pertinent case information, interpretations of the case information, and anticipated case branch points, (2) a PowerPoint that contains pertinent case lab information and X-ray to be used during the case simulation, (3) a PowerPoint that contains teaching points for the debriefing session, and (4) an evaluation form that contains recommended care actions. A group simulation case scenario was chosen to promote clinical decision making and to critically evaluate those management decisions. Results This case was run several times with both senior and junior emergency medicine residents, as well as pediatric fellows. Some junior residents did not recognize the object as a button battery or were unaware of the importance of immediate removal. Senior residents usually recognized the location of the battery and understood the importance of immediate removal. The case has good teaching value for medical students or mid-levels as well. Discussion The simplicity of the case lends itself best to a low-fidelity experience with individuals or a small group of residents. Expected discussion topics include a basic overview and evaluation of a foreign body ingestion, particularly a button battery, and management guidelines. The combination of participation in the simulation scenario, interactive feedback session focused on debriefing questions, and review of the brief PowerPoint lecture addressed all of the listed objectives for the learners. The case was definitively effective in teaching about button battery ingestions.
