It is therefore crucial for providers to be prepared when cases arise. Simulations allow providers and trainees to practice rare events with potentially severe consequences with a narrow margin for error in a controlled environment. OBJECTIVE: The objective for this article is to describe the successful implementation of a LAST simulation scenario in order to assist other institutions in organizing similar simulations, as well as to describe the importance of this particular simulation. METHODS: This simulation requires access to a simulation mannequin and OR setup. It involves a 2-year-old male undergoing a hypospadias repair who experiences LAST. Residents are expected to diagnose LAST and manage the patient using pediatric advanced life support (PALS) and intralipid. We conducted the simulation yearly for CA1 residents in 1-hour sessions with three to five learners at a time. Evaluation was done using the Anesthetists’ Non-Technical Skills (ANTS) assessment tool, as well as direct observation during the simulation and debriefing session and a follow-up survey sent to participants. RESULTS: Five cohorts of 25-28 anesthesiology residents have completed this simulation. Common areas for improvement include delayed recognition of LAST and not using the ASRA LAST checklist. Most participants were knowledgeable about the treatment of LAST and knew the pediatric dosing, but still reported finding the simulation valuable for both their skills and confidence. CONCUSIONS: Teaching about LAST is critical for all anesthesiology residents, as this is a rare but can’t-miss diagnosis. This simulation scenario is a useful and broadly applicable resource to allow residents to practice this critical learning, and residents consistently provide positive feedback about their experience.en-USPediatricsAnesthesiaToxicityAnesthesiologyPoster
