Purpose:
We report a case in which the use of semaglutide for weight loss was associated with delayed gastric emptying and intraoperative pulmonary aspiration of gastric contents.
Clinical Features:
A 42-yr-old patient with Barrett's esophagus underwent repeat upper gastrointestinal endoscopy and ablation of dysplastic mucosa. Two months earlier, the patient had started weekly injections of semaglutide for weight loss. Despite having fasted for 18 hr, and differing from the findings of prior procedures, endoscopy revealed substantial gastric content, which was suctioned before endotracheal intubation. Food remains were removed from the trachea and bronchi using bronchoscopy. The patient was extubated four hours later and remained asymptomatic.
Conclusion:
Patients using semaglutide and other glucagon-like peptide 1 agonists for weight management may require specific precautions during induction of anesthesia to prevent pulmonary aspiration of gastric contents.
