When a patient undergoes anesthesia, there are inherent risks that the providers should protect the patient from. Despite adherence to fasting guidelines established by the American Society of Anesthesiologists (ASA), patients undergoing anesthesia continue to experience intrapulmonary aspiration of gastric contents. There are several factors that delay gastric emptying, including coexisting disease, trauma, pain, and opioid use. Gastric ultrasound assessment of the gastric antrum is a relatively new technology in anesthesia and can be used to assess the gastric antrum and provide information to anesthesia providers regarding the risk of aspiration in the perioperative period. The primary aim of this project was to develop evidence-based practice (EBP) guidelines for using point-of-care ultrasound (POCUS) of the stomach as a preoperative aspiration risk stratification tool. In addition to the primary aim, secondary objectives included developing a comprehensive plan to implement the guidelines as established, a comprehensive plan to monitor and measure the guidelines' effect, and a comprehensive plan to adjust the guidelines if the outcomes are less than desirable. A literature search, review, and synthesis were conducted to establish the background of gastric ultrasound in anesthesia and to determine if the measurements were accurate. Guidelines were developed for theoretical implementation at a level-one trauma center in the midwestern United States. Following the implementation of the guidelines, a retrospective review will be conducted with measurement and analysis of outcomes, and adjustments will be made, if necessary, as described by the comprehensive adjustment plan. By using POCUS preoperatively, the risk of perioperative aspiration is reduced.
