Podcast # 501: Take Down Potions 

Author: Jared Scott, MD

Educational Pearls:

  • Study from Hennepin County EM studied the efficacy of different drugs for agitation, which included 737 patients
  • Most patients in this study were male and *surprise* drunk
  • Compared doses of common sedatives with primary outcome of sedation at 15 minutes (all intramuscular)
    • haloperidol 5 mg
    • ziprasidone 20 mg
    • olanzapine 10 mg
    • midazolam 5 mg
    • haloperidol 10 mg with the main outcome of agitation at 15 minutes
  • Intramuscular midazolam resulted in the lowest level of agitation at 15 minutes, followed by ziprasidone. There were no differences in adverse effects.
