The Impact of FDA Warnings on GLP-1 Medications and Surgery
The recent FDA update discussed in The Medical Letter's Brief in November 2024 has brought to light critical concerns regarding the use of GLP-1 receptor agonists, such as Ozempic, Wegovy, Mounjaro, and Zepbound, in patients scheduled for elective surgeries. These medications, widely prescribed for diabetes and weight management, have been linked to delayed gastric emptying, which can result in retained stomach contents despite proper fasting. This poses a significant risk of pulmonary aspiration during surgical procedures, a rare but serious complication.
The FDA's warning emphasizes the need for heightened awareness and proactive measures to mitigate these risks. Healthcare providers must now navigate the challenge of ensuring patient safety without compromising the benefits of GLP-1 medications. This calls for an innovative and reliable approach to preoperative assessment.
Understanding Gastric Emptying and Aspiration Risks
Gastric emptying is the process by which the stomach transfers its contents to the small intestine. For patients on GLP-1 receptor agonists, this process can be significantly delayed, increasing the risk of aspiration during surgery. Aspiration occurs when stomach contents are regurgitated and inhaled into the lungs, potentially leading to severe respiratory complications.
Traditional fasting guidelines, which rely on fixed timeframes, often fail to account for individual variations in gastric emptying. This is particularly concerning for patients with conditions like diabetes, obesity, or those on medications affecting gastrointestinal motility. As a result, there is a growing need for personalized assessment tools that can provide real-time insights into gastric content and volume.
Revolutionizing Patient Assessment with Point-of-Care Gastric Ultrasound
Point-of-care gastric ultrasound has emerged as a game-changer in preoperative assessment. This non-invasive technique allows clinicians to visualize stomach contents in real-time, offering an objective evaluation of aspiration risk. Using a curvilinear probe, healthcare providers can assess the gastric antrum, identifying whether the stomach is empty, contains clear fluids, or solids.
The Perlas antral grading system is an established method for quantifying aspiration risk based on ultrasound findings. By calculating the cross-sectional area (CSA) of the gastric antrum, clinicians can estimate the volume of gastric contents, enabling informed decisions on whether to proceed with surgery or adjust the anesthesia plan.
Best Practices for Implementing Gastric Ultrasound in Clinical Settings
Incorporating gastric ultrasound into preoperative protocols requires a structured approach to ensure consistency and reliability. Here are some best practices for successful implementation:
- Consistent Patient Positioning: Position patients in the right lateral decubitus position to achieve optimal visualization of the gastric antrum.
- Standardized Measurement Techniques: Train clinicians to identify anatomical landmarks and apply standardized methods for measuring gastric content volume.
- Interdisciplinary Communication: Foster collaboration among anesthesia, surgery, and nursing teams to integrate ultrasound findings into perioperative pathways.
- Simulation-Based Training: Utilize simulation platforms to enhance skill acquisition and provide hands-on practice in a controlled environment.

Future Directions: Advancing Patient Safety with Innovative Training Solutions
As the clinical landscape evolves, the integration of advanced diagnostic tools like gastric ultrasound will become increasingly important. Future directions in patient safety will likely include the development of AI-driven measurement techniques and cloud-based education platforms that expand access to high-quality training.
By standardizing image interpretation and assessment, healthcare institutions can ensure consistency and reliability in clinical practice. This will not only improve perioperative outcomes but also foster a culture of continuous education and interdisciplinary collaboration. The adoption of innovative training solutions, such as those offered by SonoSim, will be instrumental in advancing patient safety and enhancing the quality of care.
In conclusion, the use of gastric ultrasound for preoperative assessment in patients on GLP-1 medications represents a significant advancement in clinical practice. By providing real-time, non-invasive evaluation of stomach contents, this technique addresses the urgent need for individualized patient assessment, ensuring safer surgical outcomes.
