Randomized Controlled Trial Multicenter Study
The Use of Tranexamic Acid to Reduce the Need for Nasal Packing in Epistaxis (NoPAC): Randomized Controlled Trial.
Epistaxis is a common emergency department (ED) presentation and, if simple first aid measures fail, can lead to a need for anterior nasal packing. Tranexamic acid is an agent that contributes to blood clot stability. The aim of this study is to investigate the effectiveness of topical intranasal tranexamic acid in adult patients presenting to the ED with persistent epistaxis, and whether it reduces the need for anterior nasal packing. ⋯ In patients presenting to an ED with atraumatic epistaxis that is uncontrolled with simple first aid measures, topical tranexamic acid applied in the bleeding nostril on a cotton wool dental roll is no more effective than placebo at controlling bleeding and reducing the need for anterior nasal packing.

Randomized Controlled Trial
Intravenous Haloperidol Versus Ondansetron for Cannabis Hyperemesis Syndrome (HaVOC): A Randomized, Controlled Trial.
Little is known about the cause or optimal treatment of hyperemesis in habitual cannabis users. Anecdotal evidence supports the use of haloperidol over traditional antiemetics for this newly recognized disorder. We compare haloperidol with ondansetron for cannabis hyperemesis syndrome. ⋯ In this clinical trial, haloperidol was superior to ondansetron for the acute treatment of cannabis-associated hyperemesis. The efficacy of haloperidol over ondansetron provides insight into the pathophysiology of this now common diagnosis in many EDs.
