Abstract

In a meta-analysis of 28 observational studies involving 185,414 patients, glucagon-like peptide-1 receptor agonist exposure was not associated with .

  • Glucagon-like peptide-1 receptor agonist exposure is associated with an increased risk of in fasted patients undergoing procedures requiring anaesthesia.
  • The odds ratio for residual gastric contents among patients using glucagon-like peptide-1 receptor agonists was 5.96 (95% CI 3.96-8.98), indicating a significant association.
  • Withholding at least one dose of glucagon-like peptide-1 receptor agonist before a procedure was associated with lower odds of residual gastric contents, with an odds ratio of 0.51 (95% CI 0.33-0.81).
  • Despite the increased risk of residual gastric contents, there was no evidence indicating an increased risk of pulmonary aspiration for patients using glucagon-like peptide-1 receptor agonists.
