Study objectivesTo evaluate the efficacy (length of stay in the emergency department and failure rate of Bier's block) and safety profile (death and major complications) of Bier's block in its use for manipulation and reduction of paediatric forearm fractures.MethodsThis is a retrospective cohort study of pediatric patients in KKWomen's and Children's Hospital Children's Emergency Department with forearm fractures between Jan 2003 and Dec 2014 who underwent manipulation and reduction using Bier's block. Demographic data, time from registration to discharge, major complications and success rate were collated in a standardized data collection form. A subanalysis of the Bier's block group from 2009 to 2014 was performed and compared to a corresponding data set of paediatric patients who underwent manipulation and reduction of forearm fractures using ketamine for procedural sedation from 2009 to 2014.Results1781 cases of paediatric forearm fractures were analysed. The mean age of patients in the Bier's block group was 12.0 years (range 5.5–17.8 years old). Of all patients undergoing Bier's block, 1471 out of 1781 patients were male (82.7%). The mean length of stay (LOS) in the department was 168±72min, measured from time of registration till departure. From our subanalysis of data from 2009 to 2014, the mean LOS for the Bier's block group was shorter − 170min compared to 238min for the ketamine group (P <0.0001).2 patients had failed Bier's block which required a repeat procedural sedation using ketamine. 96% of patients who underwent Bier's block were discharged with an outpatient orthopaedic appointment. There were no deaths or major complications identified in our study.ConclusionBier's block is a safe technique for reduction of fractures when used in the appropriate population and fracture types, with a low failure rate and no major complications including death. Compared to the ketamine group, it has a shorter length of stay in the emergency department. We recommend the adoption of this practice for manipulation and reduction of pediatric forearm fractures in the Emergency Department with a formalised protocol to reduce and prevent any human errors that can potentially result in complications.
