Military servicemembers in combat operations often sustain injuries to the extremities from highspeed projectiles, resulting in bleeding and comminuted open fractures. Severe injury with bone fragmentation can result in limb amputation. Surgical treatment options include materials that promote osteogenesis and bone proliferation, such as growth hormones, stem cells, or mineralized matrix adjuncts. However, none of these are amenable to use by the first responder, nor do they address the question of hemorrhage control, which is a common problem in traumatic injuries. ⋯ These findings indicate that a fibrinogen?thrombin matrix may be a useful as an immediate response product to enhance fracture healing. Salmon fibrinogen?thrombin has the advantages of cost and a pathogen profile compared to mammalian fibrinogens.

The purpose of this study is to evaluate the use of the LMA Supreme® (LAM) as a combat supraglottic airway for U. S. ⋯ It is imperative to continuously evaluate and compare existing management options for airway control as requirements and technologies change. Providing our Special Operators with the most advanced and reliable medical equipment is of the utmost importance, and it is our intention here to compare the LMA Supreme with the currently fielded King LT-D® (King Systems) to determine whether the LMA Supreme may be a viable alternative supraglottic airway.

Case Reports
Abdominal aortic tourniquet controls junctional hemorrhage from a gunshot wound of the axilla.
Junctional hemorrhage, bleeding from the areas at the junction of the trunk and its appendages, is a difficult problem in trauma. These areas are not amenable to regular tourniquets as they cannot fit to give circumferential pressure around the extremity. ⋯ The present case report describes an off-label use of the Abdominal Aortic Tourniquet™ in the axilla and demonstrates its safety and effectiveness of stopping hemorrhage from a challenging wound. To our knowledge, the present report is the first human use of a junctional tourniquet to control an upper extremity junctional hemorrhage.

The use of traditional sedatives and analgesics in intubated patients can have undesired hemodynamic consequences with increases in sedation exacerbating hypotension and potentially avoidable morbidity and mortality. This project compared 50 intubated patients using traditional analgesics and sedatives to 20 intubated patients using ketamine with the hypothesis that there would be a significant difference in subsequent blood pressure drop between the two groups. ⋯ Additionally, some hypotensive patients had traditional analgesics and sedatives withheld altogether, which did not occur within the ketamine group. Due to the reduced side-effect profile, deployed medical providers should have increased training with and use of ketamine in the pre-hospital setting.

Tourniquets on casualties in war have been loose in 4%?9% of uses, and such slack risks death from uncontrolled bleeding. A tourniquet evidence gap persists if there is a mechanical slack?performance association. ⋯ Any slack presence in the strap impaired tourniquet performance. More slack had worse results. Trainers can now instruct tourniquet users with concrete guidance.
