Risk factors for delayed gastric emptying include not only diabetes, but also many medications such as opioids. We sought to use gastric POCUS to assess for delayed gastric emptying in patients taking methadone, who are part of an understudied patient population.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>We conducted a cross\u2010sectional observational cohort study of adult inpatients receiving methadone for opiate use disorder. Stomachs of hospitalized inpatients taking methadone were scanned using POCUS after an overnight fast, and gastric antral contents were assessed and measured using standardized methods. Patient characteristics were compared using the nonparametric Wilcoxon test and Fisher's exact test.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Using gastric POCUS, we found that 11 of 19 patients (57.9%) had \u201chigh risk\u201d stomachs by a simulated perioperative assessment, despite an overnight fast.
