Ultrasound-guided stellate ganglion block (SGB) is an injection of local anesthetic (8mL of 0.5% ropivacaine) in the neck to temporarily block the cervical sympathetic trunk which controls the body's fight-or-flight response. This outpatient procedure takes less than thirty minutes and is immediately effective. Our goal was to determine if a left-sided stellate ganglion block is effective for treating posttraumatic stress disorder (PTSD) symptoms. While right-sided SGB has been extensively studied, left-sided SGB has not been formally evaluated for this indication. ⋯ Based on our sample of 205 patients receiving SGB for PTSD, we concluded that at least 4.4% did not respond to a right-sided SGB but did have a significant response to a left-sided SGB.

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.

The U.S. Air Force (USAF) conducted a program of research to develop and disseminate reliable and valid criteria for partner and child maltreatment (comprising abuse [physical, emotional/psychological, and sexual] and neglect). These criteria are now used in all branches of the U.S. military. The U.S. Army was the first service outside the USAF to adopt the criteria sets and computerized decision support tool but maintained the original committee composition (the "Case Review Committee" [CRC]) instead of adopting the entire assessment, allegation determination, and treatment planning process (the "Field-tested Assessment, Intervention-planning, and Response" [FAIR] system). The Army commissioned this study to compare the CRC and FAIR processes by testing (1) intra-committee process (i.e., three facets of committee functioning-fidelity to regulations, cohesion and team process, outsized influence of unit representatives); (2) coordinated community response to maltreatment (i.e., perceptions of fairness to alleged offenders and victims, impact on unit representatives, and (3) collaboration between the Family Advocacy Program (FAP, the military's maltreatment response agency) and outside agencies; and (4) the time expended and cost. ⋯ Results indicated that the CRC and FAIR processes cost almost identical amounts to run and that the FAIR system was superior in ways most likely to impact service members: (1) independent observers judged its meetings to be more faithful to Army and DoD Instructions; (2) unit representatives were more likely to attend and believed the FAIR system to be fairer (to both alleged offenders and victims) and better functioning. Care should be taken, however, in nurturing relationships between FAP and (1) unit representatives and (2) outside agencies, which may have weakened during FAIR.
