Study ObjectiveThe primary objective of this study was to examine the common usage patterns of droperidol in the relatively unrestricted environment of an urban, academic medical center. We focused specifically on the most common use of droperidol in our department: patients with a chief complaint of abdominal pain, nausea, and/or vomiting.MethodsFor this retrospective, observational, single-center study, we extracted records of all administrations of droperidol from August 2019 to August 2020. Patients with a chief complaint of abdominal pain, nausea, or vomiting, or any combination thereof, were included in data analysis.ResultsBetween April 2019 to August 2020, 830 discrete patient visits involving droperidol administration were identified, comprising 706 patients. The average age was 39 years old with a range of 15 to 80. Seven patients (0.08%) were younger than 18, and 35 (4%) were older than 65. Five hundred sixty-five patients (68%) were female. Droperidol doses ranged from 0.625 mg to 5 mg intravenous (IV), with a median dose of 0.625 mg (interquartile range 0.625-1.25 mg), with 590 patients (71%) receiving a dose of 0.625 mg. Only 19 patients (2.3%) had a documented adverse event. Seven had akathisia or restlessness, 7 had anxiety or agitation, 3 had dystonia or stiffness, 1 had fatigue, and 1 had dizziness. For the entire cohort, there were no cardiac dysrhythmias, syncope, seizures, other major adverse events, or fatalities recorded.ConclusionAt one institution, droperidol is being used commonly for the chief complaints of abdominal pain, nausea, and/or vomiting. The preferred dosing is nearly universally below the 2.5 mg IV dose for which the FDA warning applies. Similar to previous studies, identification of adverse events was rare, and no major adverse outcomes such as dysrhythmia or death were identified.Copyright © 2024. Published by Elsevier Inc.
