On this episode of The Sonography Lounge hosts Lori and Trisha sit down with Dr. Charlotte Derr & Dr. Allyson Hansen to discuss the GUARD Protocol (Gastric Ultrasound for Aspiration Risk Determination).
With the increased use of GLP-1 Agonists (Semaglutide, with brand names such as Ozempic, Wegovy, Rybelsus, Etc) for both diabetes and weight loss, there has been an increased number of aspirations in patients undergoing procedures. One of the effects of GLP-1 agonists is delayed gastric emptying which keeps patients feeling "full" thus reducing the desire to eat and overall caloric intake and blood sugar variations. Typically 6-8 hours not eating is enough time for a patient about to undergo an elective procedure to digest and empty their stomachs thus reducing the risk of aspiration while under anesthesia. With patients on GLP-1 agonists, we are seeing gastric contents remaining for several days after the last meal which can increase the risk of aspiration.
Dr. Derr and Dr. Hansen, discuss how they are using ultrasound and the GUARD protocol to determine the volume of food in a patient's stomach before elective and emergency procedures. This quick and simple bedside technique can drastically alter a provider's pre-procedure course of action.
