Background: Pulmonary aspiration is a significant risk of general anesthesia and is related to increased perioperative morbidity and mortality. Gastric point-of-care ultrasound (POCUS) has been shown to be a reliable indicator of gastric contents and volume, and it can be used in the perioperative setting to detect gastric contents and make informed clinical decisions to prevent aspiration events.
Purpose: This project aimed to educate Certified Registered Nurse Anesthetists (CRNAs) at Washington University in the use of point-of-care ultrasound to assess gastric contents prior to surgery with the overall goal of improving knowledge, skills, and attitudes towards this practice among participants.
Methods: Participants were provided with written materials and a pre-recorded lecture detailing the current state of gastric POCUS research and how to perform and interpret a gastric POCUS assessment. They then attended a live session where each participant performed their own hands-on POCUS exams with various prandial states. A pre- and post-survey design was used to determine changes in knowledge and attitudes among participants in response to the education.
Results/Discussion: Ten CRNAs participated in the education. All participants successfully completed the modules and attended the live education. Post-survey responses showed significant improvement in both knowledge, and attitudes at three separate time points following the education when compared to the pre-surveys. These results suggest brief hands-on education can significantly improve knowledge, and attitudes regarding gastric POCUS for CRNAs.
