A comprehensive analysis of in-hospital adverse events after scopolamine administration: insights from a retrospective cohort study using a large nationwide inpatient database

In this cohort study, perioperative scopolamine usage was associated with a significantly increased risk of in-hospital adverse events, both within the 70 + age cohort and among the 20-29, 30-39, 40-49, 50-59, and 60-69 age cohorts after major surgery. These findings highlight the need for careful assessment of scopolamine's risks and benefits, especially for patients aged 40 and older. Scopolamine may be most suited for post-discharge nausea and vomiting in ambulatory patients and clinicians should reassess its standard use for postoperative nausea and vomiting, favoring shorter-acting agents with fewer side effects.
