Educational Pearls:
A recent randomized controlled trial compared ondansetron 8 mg IV with droperidol 2.5 mg IV for the treatment of nausea & vomiting in the emergency department.
Overall, droperidol and ondansetron had similar primary outcomes in acute nausea control
Symptom improvement in 93% of patients receiving droperidol vs. 87% receiving ondansetron (P = 0.362)
Secondary measures were, however, statistically significantly different between groups
Patients needed fewer rescue/additional antiemetics in the droperidol group (16%) compared with the ondansetron group (37%); p = 0.016
Similarly, more patients in the droperidol group reported they achieved the desired effect of the medication (85% vs. 63%; p = 0.006)
Patients receiving droperidol did experience increased drowsiness
40% in the droperidol group vs. 11% in the ondansetron group
The trial did not assess the length of stay in the ED after administering medications, which is a potential avenue for future research.
