This report reviews the recent literature on fluid resuscitation from hemorrhagic shock and considers the applicability of this evidence for use in resuscitation of combat casualties in the prehospital Tactical Combat Casualty Care (TCCC) environment. A number of changes to the TCCC Guidelines are incorporated: (1) dried plasma (DP) is added as an option when other blood components or whole blood are not available; (2) the wording is clarified to emphasize that Hextend is a less desirable option than whole blood, blood components, or DP and should be used only when these preferred options are not available; (3) the use of blood products in certain Tactical Field Care (TFC) settings where this option might be feasible (ships, mounted patrols) is discussed; (4) 1:1:1 damage control resuscitation (DCR) is preferred to 1:1 DCR when platelets are available as well as plasma and red cells; and (5) the 30-minute wait between increments of resuscitation fluid administered to achieve clinical improvement or target blood pressure (BP) has been eliminated. ⋯ Maintained as recommendations are an emphasis on hypotensive resuscitation in order to minimize (1) interference with the body's hemostatic response and (2) the risk of complications of overresuscitation. Hextend is retained as the preferred option over crystalloids when blood products are not available because of its smaller volume and the potential for long evacuations in the military setting.

Multicenter Study Observational Study
Prehospital and en route cricothyrotomy performed in the combat setting: a prospective, multicenter, observational study.
Airway compromise is the third most common cause of potentially preventable combat death. Surgical cricothyrotomy is an infrequently performed but lifesaving airway intervention. There are limited published data on prehospital cricothyrotomy in civilian or military settings. Our aim was to prospectively describe the survival rate and complications associated with cricothyrotomy performed in the military prehospital and en route setting. ⋯ In our prospective, multicenter study evaluating cricothyrotomy in combat, procedural success was higher than previously reported. In addition, the majority of cricothyrotomies were performed by the evacuation helicopter medic rather than the prehospital combat medic. Prehospital military medics should receive training in decision making and be provided with adjuncts to facilitate this lifesaving procedure.

Randomized Controlled Trial
Evaluation of Contingency Telemedical Support to Improve Casualty Care at a Simulated Military Intermediate Resuscitation Facility: The EM-ANGEL Study.
We sought to determine whether Contingency Telemedical Support (CTS) improves the success rate and efficiency of primary care providers performing critical actions during simulated combat trauma resuscitation. Critical actions included advanced airway, chest decompression, extremity hemorrhage control, hypothermia prevention, antibiotics and analgesics, and hypotensive resuscitation, among others. ⋯ In this model, real-time telementoring of simulated trauma resuscitation was feasible and improved accuracy and efficiency of non?emergency-trained resuscitators. Clinical validation and replicated study of these findings for guiding remote damage control resuscitation are warranted.

Randomized Controlled Trial Comparative Study
Intra-articular Morphine versus Lidocaine for Acute Knee Pain.
The authors conducted an unfunded randomized controlled trial approved by the Brooke Army Medical Center (BAMC) Institutional Review Board (IRB) to determine the possible efficacy of intra-articular morphine for pain in acute knee injuries. ⋯ Further investigation with a larger sample is required to explore whether these results are statistically significant and the possible superiority of intra-articular morphine to lidocaine for acute knee pain.

Comparative Study
Evaluation of NuStat?, a Novel Nonimpregnated Hemostatic Dressing, Compared With Combat Gauze in Severe Traumatic Porcine Hemorrhage Model.
Uncontrolled hemorrhage remains one of the most challenging problems facing emergency medical professionals and a leading cause of traumatic death in both battlefield and civilian environments. Survival is determined by the ability to rapidly control hemorrhage. Several commercially available topical adjunct agents have been shown to be effective in controlling hemorrhage, and one, Combat Gauze (CG), is used regularly on the battlefield and for civilian applications. However, recent literature reviews have concluded that no ideal topical agent exists for all injuries and scenarios. The authors compared a novel nonimpregnated dressing composed of cellulose and silica, NuStat (NS), to CG in a lethal hemorrhagic groin injury. These dressings were selected for their commercial availability and design intended for control of massive hemorrhage. ⋯ In this porcine model of uncontrolled hemorrhage, NS improved immediate hemorrhage control, stability, and use of fluid in a 60-minute severe porcine hemorrhage model. In this study, NS demonstrated equivalence to CG at achieving long-term hemostasis and the prevention of rebleed after application. NS was shown to be an efficacious choice for hemorrhage control in combat and civilian emergency medical service environments.
