Perioperative aspiration of gastric contents is a rare but serious adverse event. The risk of aspiration can be estimated by perioperative evaluation of stomach contents with ultrasound using a validated technique and scoring system. A lack of knowledge or familiarity is frequently cited by anesthesia providers as a rationale for not performing perioperative ultrasound assessments. The purpose of this study is to determine whether novice ultrasonography users (medical students, undergraduates, or inexperienced anesthesiologists) can be effectively taught a technique to evaluate stomach contents as compared to experts in ultrasonography.
