Abstract: | BackgroundDroperidol is a dopamine receptor antagonist that functions as an analgesic, sedative, and antiemetic. In 2001, the U.S. Food and Drug Administration required a black box warning in response to case reports of QT prolongation and potential fatal arrhythmias. The aim of this study was to evaluate the effectiveness and safety of droperidol in patients presenting to a United States Emergency Department (ED).MethodsObservational cohort study of all droperidol administrations from 1/1/2012 through 4/19/2018 at an academic ED. The primary endpoint was mortality within 24 h of droperidol administration. Secondary endpoint included use of rescue analgesics.ResultsA total of 6,881 visits by 5,784 patients received droperidol of whom 6,353 visits authorized use of their records for research, including 5.4% administrations in children and 8.2% in older adults (≥65). Droperidol was used as an analgesic for pain (N = 1,387, 21.8%) and headache (N = 3,622, 57.0%), as a sedative (N = 550, 8.7%), and as an antiemetic (N = 794, 12.5%). No deaths secondary to droperidol administration were recorded within 24 h. Need for rescue analgesia occurred in 5.2% of patients with headache (N = 188) and 7.4% of patients with pain (N = 102); 1.1% of patients with headache received rescue opioids (N = 38) after droperidol, as did 5.4% of patients with pain other than headache (N = 75). No patients had fatal arrhythmias. Akathisia occurred in 2.9%.ConclusionNo fatalities were seen among this large cohort of patients who received droperidol in the ED. Our findings suggest droperidol's effectiveness and safety when used as an analgesic, antiemetic and/or sedative. |
