Adverse events in pediatric ketamine sedations with or without morphine pretreatment.

Objective: To assess outcomes between 2 groups of patients receiving ketamine for procedural sedations in our pediatric emergency department. Our hypothesis is that there is no difference in the number of adverse events in ketamine sedations with and without morphine pretreatment.

Methods: This was a retrospective cohort study of all ketamine sedation records over 15 months.
