To describe the magnitude of ketamine doses administered in the ED, to identify an appropriate product to minimise risk of administration errors and diversion. Retrospective audit of patients prescribed ketamine in two mixed adult/paediatric EDs over 12 months. Ketamine was administered to 386 patients (722 doses). The most common dose was ≤20 mg (52.1%), followed by 21-50 mg (30.5%). Overall, 215 patients required one dose only (71 received a dose ≤20 mg), while 299 required no more than two doses. Over three-quarters of ketamine doses were ≤50 mg; therefore, 50 mg in 1 mL may be an appropriate product. |
