Effectively and rapidly controlling significant junctional hemorrhage is an important effort of Tactical Combat Casualty Care (TCCC) and can potentially contribute to greater survival on the battlefield. Although the US Food and Drug Administration (FDA) has approved labeling of four devices for use as junctional tourniquets, many Special Operations Forces (SOF) medics do not carry commercially marketed junctional tourniquets. As part of ongoing educational improvement during Special Operations Combat Medical Skills Sustainment Courses (SOCMSSC), the authors surveyed medics to determine why they do not carry commercial tourniquets and present principles and methods of improvised junctional tourniquet (IJT) application. The authors describe the construction and application of IJTs, including the use of available pressure delivery devices and emphasizing that successful application requires sufficient and repetitive training.

Airway compromise is the second leading cause of preventable death on the battlefield. Unlike a cricothyrotomy, supraglottic airway (SGA) placement does not require an incision and is less technically challenging. We compare survival of causalities undergoing cricothyrotomy versus SGA placement. ⋯ We found no difference in short-term outcomes between combat casualties who received an SGA vs cricothyrotomy. Military prehospital personnel rarely used either advanced airway intervention during the recent conflicts in Afghanistan and Iraq.

We investigated interoperability for a first aid provider to perform simulated use of three tourniquet models of maximal, moderate, and minimal familiarity. ⋯ Timesaving strongly favored the model with which the user had maximal familiarity. In theory and simulation, interoperability bears costs in successfully attaining it, in maintaining it, and in failing either. The user's familiarity with tourniquet model was associated with improved interoperability as seen by improved performances. If multiple models are fielded, then organizations may plan on extra spending, supplying, training, and managing.

An Army Reserve Combat Medic's training is focused on knowledge attainment, skill development, and building experience and training to prepare them to perform in austere conditions with limited resources like on the battlefield. Unfortunately, the exposure to skills they may be responsible for performing is limited. Research shows that greater than 90% of battlefield deaths occur in the prehospital setting, 24% of which are potentially survivable. Literature demonstrates that 91% of these deaths are related to hemorrhage; the remaining are related to other causes, including airway compromise. The skill and decision-making of this population are prime targets to optimize outcomes in the battlefield setting. ⋯ Supplementing the training of Army Reserve Combat Medics with the utilization of anesthesia providers is an effective platform. This exercise imparted confidence in this population of military providers. This is critical for decision-making capabilities, performance, and the prevention of potentially survivable mortality on the battlefield.

Case Reports
Bringing Resuscitative Endovascular Balloon Occlusion of the Aorta (REBOA) Closer to the Point of Injury.
The management of noncompressible torso hemorrhage remains a significant issue at the point of injury. Resuscitative endovascular balloon occlusion of the aorta (REBOA) has been used in the hospital to control bleeding and bridge patients to definitive surgery. Smaller delivery systems and wirefree devices may be used more easily at the point of injury by nonphysician providers. We investigated whether independent duty military medical technicians (IDMTs) could learn and perform REBOA correctly and rapidly as assessed by simulation. ⋯ Technology for aortic occlusion has advanced to provide smaller, wirefree devices, making field deployment more feasible. IDMTs can learn the steps required for REBOA and perform the procedure accurately and rapidly, as assessed by simulation. Arterial access is a challenge in the ability to perform REBOA and should be a focus of further training to promote this procedure closer to the point of injury.
