    ObjectiveThe aim of this study was to determine the prevalence, safety (as measured by the incidence of adverse events), and effectiveness (as measured by the incidence of intubations) of ketamine sedation in patients with acute behavioral disturbance (ABD) during air medical retrieval.MethodsThis was a retrospective observational study. Eligible patients were identified by searching the electronic databases of 2 air medical retrieval services in Queensland, Australia, for adult patients with ABD transported between January 1, 2015, and June 30, 2016. Data abstraction was performed as per standard chart review criteria. The incidences of intubations and adverse reactions were the main outcomes.ResultsOne hundred twenty-two patients met the inclusion criteria. Thirty-one (25.4%) patients were intubated, 21 (17.2%) for airway protection/respiratory depression and 10 (8.1%) for persistent ABD. Twenty-one (17.2%) patients received ketamine, 3 of whom (14.3%) were intubated for persistent ABD. Nine (42.9%) patients developed hypertension after ketamine, 2 of whom needed intervention. One patient developed hypoxia after ketamine that resolved without intervention, and 1 patient developed increased secretions. No patients developed nausea, vomiting, emergence phenomena, apnea, or laryngospasm.ConclusionOur study suggests that ketamine is a safe and effective agent for sedating patients with ABD during air medical retrieval.Copyright © 2017 Air Medical Journal Associates.
