IntroductionKetamine is a phencyclidine derivative first used in clinical practice in the 1970's. Specifically within the emergency department (ED), ketamine is utilized for a wide variety of indications including but not limited to procedural sedation, rapid sequence intubation, agitation, and pain. As providers continue to utilize ketamine more frequently and for additional indications, additional data describing its safety and efficacy in the ED setting is warranted.ObjectivesTo describe current trends in ketamine usage within a large tertiary-care Emergency Department.MethodsAll patients receiving intravenous (IV) or intramuscular (IM) ketamine within the Emergency Department between January 1, 2019 and December 31, 2019 were eligible for study inclusion. Patients were excluded from the study if they were less than 18 years of age, pregnant, or incarcerated. Data was collected using a report of ketamine removal from the ED automatic dispensing cabinets, with administration confirmed by electronic medical record review.ResultsDuring the study period, 170 patients received 195 doses of ketamine for the indications of agitation, procedural sedation, rapid sequence intubation, pain, sedation, seizure, status asthmaticus, and unknown. Patients were mostly male (74%) with a mean age of 45 years (range 20-97 years). The most common indications for ketamine administration were agitation and procedural sedation. For agitation, ketamine was utilized as first line therapy in 45% of patients. Seventy-seven percent of these patients did not require an additional sedative agent up to 60 min after ketamine administration. Procedural sedations were most commonly orthopedic reductions, and ketamine was given more frequently in combination with propofol than as monotherapy. Five percent of patients had an adverse event documented in the electronic medical record, with a single incidence of ketamine induced laryngospasm requiring intubation.ConclusionThis descriptive review supports the versatility, safety, and efficacy of ketamine use within a large, tertiary-care, academic emergency department. Larger, prospective studies are warranted to draw further conclusions regarding ideal ketamine utilization within the emergency department.Copyright © 2021 Elsevier Inc. All rights reserved.
