What this Trial Is About
This research investigates the use of gastric ultrasonography as a tool to assess stomach contents in adult patients treated with GLP-1 receptor agonists who are undergoing scheduled surgery. These medications, commonly used for diabetes and obesity, can delay stomach emptying and may increase the risk of lung aspiration during anesthesia. The study aims to better understand this risk and improve airway management during surgery by using a non-invasive ultrasound technique. The study is observational and involves adult patients aged 18 to 90 years who are receiving GLP-1 receptor agonists and have fasted for 6 to 8 hours before surgery. Trained anesthesiologists will perform gastric ultrasounds immediately before anesthesia induction, assessing stomach contents in different body positions. The procedure follows established methods and does not alter routine surgical or anesthetic care. Participants will undergo a single ultrasound evaluation just before anesthesia. Researchers will collect data on gastric content volume and appearance, as well as patient weight, height, and body mass index. This information will be recorded systematically and analyzed later. The study involves no changes to usual care, no additional risks, and no extra costs for participants. Results will be shared through scientific channels.
