Summary

This project explores the elevated risk of pulmonary aspiration during anesthesia in patients undergoing GLP-1 agonist therapy, which prolongs gastric emptying. Despite standard fasting guidelines (6 hours for solids, 2 hours for liquids), some patients still experience aspiration, indicating that GLP-1 therapy may heighten risk. The American Society of Anesthesiologists has advised pausing GLP-1 therapy before surgery, but this recommendation has faced criticism for being too broad. More data on this issue is needed, particularly concerning the effect of tachyphylaxis (reduced drug response over time) on gastric emptying.

The study proposes using gastric ultrasound as a non-invasive tool to evaluate residual gastric content and categorize patients by their aspiration risk. The study will assess the stomach's content and gastric emptying time in patients both before and after starting GLP-1 therapy, comparing results under standard fasting conditions.

The project is a national, single-center, prospective observational study targeting 50 patients, examining factors like patient demographics, GLP-1 therapy details, and gastrointestinal side effects. Data collection will occur through baseline and follow-up sonographic exams before and after therapy initiation. The study aims to improve perioperative management strategies by clarifying the risks associated with GLP-1 therapy

Conditions

  • Pulmonary Aspiration During Anaesthetic Induction

Interventions

DIAGNOSTIC_TEST

Gastric ultrasound

The sequence in which the study is conducted will be as follows, the first examination (baseline examination) will take place immediately before the appointment and prescription of GLP-1 Analoga (before the first injection). During the examination the gastric content (quality/quantity) will be determined, secondly, a baseline for gastric emptying time after oral intake of 500ml of water is collected (patient drinks water, the stomach emptying will simultaneously be tracked with gastric ultrasound). In accordance with the first endocrinological control examination (6-8 weeks after therapy initiation) the same gastric ultrasound examination is performed.
