Podcast #408: Go the hell to sleep

Author: Don Stader, MD

Educational Pearls:

Recent study showed efficacy 5mg IM midazolam > 10mg IM olanzapine > 10mg IM haloperidol for quickly sedating an agitated patient
If you have access, ketamine intravenous is the fastest
Olanzapine should be used with caution in elderly patients because of its anticholinergic properties
Ketamine can transiently worsen psychosis in some mental illness
Haloperidol is contraindicated in patients with prolonged QT
Olanzapine can be safely given intravenous as another option to your sedating arsenal
