Randomized Controlled Trial Comparative Study
Evaluation of the NIO and T.A.L.O.N Intraosseous Devices as Placed by U.S. Army Conventional Force Combat Medics-A Randomized Crossover Study.
In recent U.S. Military conflicts, hemorrhage remains the leading cause of preventable death with 30%-40% mortality rates. Management consists of effective bleeding control and rapid resuscitation with blood products. Rapid and accurate circulatory access is crucial in battlefield trauma management. This study evaluates the insertion success rate and time to successfully insert the NIO automatic intraosseous (IO) device and the Tactical Advanced Lifesaving IO Needle (TALON) manual IO device. The primary outcome is successful first attempt insertion. Secondary outcomes are the time taken for the successful insertion, user-reported "ease of use" for both devices, and user-reported device preference. ⋯ Our findings indicate that the overall insertion success rate and time to successful insertion were similar between NIO automatic IO device and the TALON manual IO device. In our study, Army combat medics learned how to use both devices rapidly but felt the NIO automatic IO device easier to use and overwhelmingly preferred this device.
