Summary

Glucagon-like-peptide-1 is a hormone released by the gut enteroendocrine cells. Its secretion occurs after each meal to enable production of insulin and inhibits the production of glucagon to lower after meal glycemia. It also inhibits gastric emptying and food intake. GLP-1 RA plays a role on GLP-1 receptors present on islet beta cells and delta cells of the pancreas to control insulin. GLP-1 receptors are also present in multiple region of the central nervous system such as the hypothalamus and hindbrain where it results in reducing food intake. For anesthesiologist it is important to understand how GLP-1 RA influence gastric emptying. Indeed, respecting a fasting period (6 hours for solid and 2 hours for liquid) before each surgery is one of the cornerstones of anesthesiology to significantly reduce the risk of pulmonary aspiration. One of the side effects of GLP-1 RA is slowing gastric emptying and increasing the risk of regurgitation in patient that observed a recommended fasting period. During 2023 a lot of cases reports have emerged of pulmonary aspiration or the presence of a full stomach in patient treated by GLP-1 RA for a type 2 diabetes. Despite recommendations made by the American Society of Anesthesiology, it is still unkown what is the best fasting period and how long patients should pause a long acting GLP-1 RA before surgery. In this observational study, we would like to determine the effect of GLP-1 RA on gastric emptying in patient scheduled for general anesthesia. We will measure and compare residual gastric content with gastric ultrasonography in patients treated by GLP-1 RA and in those who are not. We will also do these comparisons in a group of patients with type 2 diabetes treated by weekly GLP-1 RA at different days after the injection of the medication. Our hypothesis is that we will observe a reduction in gastric residue in patients who stopped weekly GLP-1 RA 7 days prior the examination compared to those who have stopped less days considering the same fasting period. This would lead us to propose an optimal duration of stopping time for GLP-1 inhibitors in the preoperative period.

Conditions

  • Diabetes Mellitus, Type 2
  • Anesthesia
  • Pulmonary Aspiration of Gastric Contents

Interventions

DEVICE

Gastric Ultrasonography

Evaluation of cross sectional area of the antrum by gastric ultrasonography in healthy patients and in patient treated by GLP-1 receptor agonists after a fasting period (6 hours for solid and 2 hours for clear liquids). For the GLP-1 receptor agonists group the gastric ultrasonochography will be repeated each 2 days during 7 days. In the non GLP-1 receptors agonists group the evaluation will be executed one time.
