ABSTRACTObjectivesMethoxyflurane is an inhalation analgesic used in the emergency department (ED) but also has minimal sedative properties. The major aim of this study was to evaluate the success rate of methoxyflurane for acute anterior shoulder dislocation (ASD) reduction. The secondary aim was to assess the impact of methoxyflurane on ED patient flow compared to propofol.MethodsA health record review was performed for all patients presenting with ASD who underwent reduction with either methoxyflurane or propofol over a 13-month period (December 2016 – December 2017). The primary outcome was reduction success for methoxyflurane, while secondary outcomes such as recovery time and ED length of stay (LOS) were also assessed compared to propofol. Patients with fracture dislocations, polytrauma, intravenous, or intramuscular opioids in the pre-hospital setting, no sedation for reduction, and alternative techniques of sedation or analgesia for reduction were excluded.ResultsA total of 151 patients presented with ASD during the study period. Eighty-two patients fulfilled our inclusion criteria. Fifty-two patients had ASD reduction with propofol while 30 patients had methoxyflurane. Successful reduction was achieved in 80% (95% CI 65.69% to 94.31%) patients who used methoxyflurane. The median recovery time and ED LOS were 30 minutes [19.3-44] and 70.5 minutes [49.3-105], which was found to be shorter for the methoxyflurane group, who had successful reductions compared to sedation with propofol.ConclusionMethoxyflurane was used successfully in 30% of the 82 patients undergoing reduction for ASD, while potentially improving ED efficiency.
