Combat casualties who die from their injuries do so primarily in the prehospital setting. Although most of these deaths result from injuries that are non-survivable, some are potentially survivable. Of injuries that are potentially survivable, most are from hemorrhage. Thus, military organizations should direct efforts toward prehospital care, particularly through early hemorrhage control and remote damage control resuscitation, in order to eliminate preventable death on the battlefield. A systems-based approach and priority of effort for institutionalizing such care was developed and maintained by medical personnel and command-directed by non-medical combatant leaders within the 75th Ranger Regiment, U...

BACKGROUND: There is little agreement on who is a good candidate for community (home or birth center) birth in the United States. METHODS: Data on n=47 394 midwife-attended, planned community births come from the Midwives Alliance of North America Statistics Project. Logistic regression quantified the independent contribution of 10 risk factors to maternal and neonatal outcomes. Risk factors included: primiparity, advanced maternal age, obesity, gestational diabetes, preeclampsia, postterm pregnancy, twins, breech presentation, history of cesarean and vaginal birth, and history of cesarean without history of vaginal birth...

REVIEW
Brad L Bennett
Based on lessons learned, many military battlefield trauma advances ultimately transition to enhance civilian trauma care. However, even with major strides to enhance battlefield hemorrhage control, it is unclear how effectively these techniques and products are being translated to civilian trauma. The purpose of this brief review is to present the evidence of current hemostatic product effectiveness, determine the evidence for transitioning of this technology to prehospital civilian application, and provide recommendations about potential use in the wilderness/austere setting...

During historic, as well as more recent, conflicts, most combat casualties who die from their injuries do so in the prehospital setting. Although many of the injuries incurred by these casualties are nonsurvivable, a number of injuries are still potentially survivable. Of those injuries that are potentially survivable, the majority are truncal, junctional, and extremity hemorrhage. Novel and effective approaches directed toward prehospital hemorrhage control have emerged in recent years, some of which can prove useful in the management of junctional hemorrhage whether in a military or civilian setting...

REVIEW
Kristi Colbenson
On-the-field evaluation of facial trauma requires a focused initial assessment of the patient's airway and breathing with a knowledge of the critical associated injuries. The initial triage in facial trauma involves assessing and protecting the athlete's airway, breathing, and cervical spine. The algorithm then requires a repeat evaluation for subtle causes of airway obstruction and aspiration risks. Final steps include control of hemorrhage, recognition of neurologic and ophthalmologic disability, and complete exposure of the athlete to examine for other associated injury...

BACKGROUND: Twenty years ago, the original Tactical Combat Casualty Care (TCCC) article was published in this journal. Since TCCC is essentially a set of best-practice prehospital trauma care guidelines customized for use on the battlefield, the presence of a journal with a specific focus on military medicine was a profound benefit to the initial presentation of TCCC to the U.S. Military. METHODS: In the two ensuing decades, which included the longest continuous period of armed conflict in our nation's history, TCCC steadily evolved as the prehospital trauma care evidence base was augmented and as feedback from user medics, corpsmen, and pararescuemen was obtained...

BACKGROUND: Hemorrhagic shock is the leading cause of trauma-related death in the military setting. Definitive surgical treatment of a combat casualty can be delayed and life-saving fluid resuscitation might be necessary in the field. Therefore, improved resuscitation strategies are critically needed for prolonged field and en route care. We developed an automated closed-loop control system capable of titrating fluid infusion to a target endpoint. We used the system to compare the performance of a decision table algorithm (DT) and a fuzzy logic controller (FL) to rescue and maintain the mean arterial pressure (MAP) at a target level during hemorrhages...

Although melatonin attenuates the increases in inflammatory mediators and reduces organ injury during trauma-hemorrhage, the mechanisms remain unclear. This study explored whether melatonin prevents liver injury after trauma-hemorrhage through the p38 mitogen-activated protein kinase (MAPK)-dependent, inducible nitrite oxide (iNOS)/hypoxia-inducible factor (HIF)-1α pathway. After a 5-cm midline laparotomy, male rats underwent hemorrhagic shock (mean blood pressure approximately 40 mmHg for 90 min) followed by fluid resuscitation...

BACKGROUND: Trauma transfusion packages for hemorrhage control consist of red blood cells, plasma, and platelets at a set ratio. Although pathogen reduction improves the transfusion safety of platelet and plasma units, there is an associated reduction in quality. This study aimed to investigate the impact of riboflavin/ultraviolet light-treated plasma or platelets in transfusion trauma packages composed of red blood cell, plasma, and platelet units in a ratio of 1:1:1 in vitro by modeling transfusion scenarios for trauma patients and assessing function by rotational thromboelastometry...

Trauma-induced coagulopathy is associated with adverse patient outcome. Animal models demonstrate that histone deacetylase inhibitors, such as valproic acid (VPA), improve survival following injury. While in-vivo data suggest that improved survival may in part be because of an attenuation of coagulopathy, it remains unknown whether this is a direct effect of the drug, or the establishment of an overall prosurvival phenotype. We thus conducted an ex-vivo experiment to determine if VPA has an effect on coagulation and platelet function...

BACKGROUND: Hemorrhage is a leading cause of preventable death on the battlefield. Timely tourniquet application to massively bleeding extremity wounds is critical for casualty survival albeit with reported adverse effects to extremity integrity. The aim of this study was to describe the immediate and short term outcomes of point of injury (POI) tourniquet applications during 'Operation Protective Edge' (OPE). METHODS: A case series study regarding tourniquet application at the POI during OPE was collected...

BACKGROUND: The resuscitation of severely injured bleeding patients has evolved into a multi-modal strategy termed damage control resuscitation (DCR). This guideline evaluates several aspects of DCR including the role of massive transfusion (MT) protocols, the optimal target ratio of plasma (PLAS) and platelets (PLT) to red blood cells (RBC) during DCR, and the role of recombinant activated factor VII (rVIIa) and tranexamic acid (TXA). METHODS: Using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) methodology, a subcommittee of the Practice Management Guidelines (PMG) Section of EAST conducted a systematic review using MEDLINE and EMBASE...

BACKGROUND: Platelet dysfunction has been described as an early component of trauma-induced coagulopathy. The platelet component of trauma-induced coagulopathy remains to be fully elucidated and translatable animal models are required to facilitate mechanistic investigations. We sought to determine if the early platelet dysfunction described in trauma patients could be recapitulated in a nonhuman primate model of polytraumatic hemorrhagic shock. METHODS: Twenty-four male rhesus macaques weighting 7 to 14 kg were subjected to 60 minutes (min) of severe pressure-targeted controlled hemorrhagic shock (HS) with and without other injuries...

BACKGROUND: In critically ill patients with colonization/infection of multidrug-resistant organisms, source control surgery is one of the major determinants of clinical success. In more complex cases, the use of different tools for sepsis management may allow survival until complete source control. CASE PRESENTATION: A 42-year-old white man presented with traumatic hemorrhagic shock. Unstable pelvic fractures led to emergency stabilization surgery. Fever ensued with diarrhea, followed by septic shock...

BACKGROUND: Choosing the appropriate endpoint for a trauma hemorrhage control trial can determine the likelihood of its success. Recent Phase 3 trials and observational studies have used 24-h and/or 30-day all-cause mortality as the primary endpoint and some have not used exception from informed consent (EFIC), resulting in multiple failed trials. Five recent high-quality prospective studies among 4,064 hemorrhaging trauma patients provide new evidence to support earlier primary endpoints...
