Evaluating the Effectiveness of a Self-instructional Ultrasound Training Program at Teaching Aspiration Risk Assessment Through Gastric Ultrasound
Stanford University
Summary
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.
Description
This study will be conducted in two arms. For part 1, we will evaluate the efficacy of the self-taught course at producing accurate reads among novice ultrasound users on ideal, cooperative, adult subjects. For part 2, we will evaluate the effectiveness of the course through an identical study that uses clinical pediatric patients as subjects. Using available literature and established standards for gastric ultrasound, a 15-minute ultrasound training video course will be designed that gives instruction on ultrasound orientation, use, and the antral scoring system of gastric contents.
