RESUMEN
BACKGROUND: Assessment and triage in an austere environment represent a major challenge in casualty care. Modern conflicts involve a significant proportion of multiple wounds, either superficial or penetrating, which complicate clinical evaluation. Furthermore, there is often poor accessibility to computed tomography scans and a limited number of surgical teams. Therefore, ultrasound (US) represents a potentially valuable tool for distinguishing superficial fragments or shrapnels from penetrating trauma requiring immediate damage-control surgery. METHODS: This retrospective observational multicenter study assessed casualties treated for 8 months by five medical teams deployed in Africa and Middle East. Two experts, who were experienced in military emergency medicine but did not take part in the missions, carried out an independent analysis for each case, evaluating the contribution of US to the following five items: triage categorization, diagnosis, clinical severity, prehospital therapeutic choices, and priority to operation room. Consensus was obtained using the Delphi method with three rounds. RESULTS: Of 325 casualties, 189 underwent US examination. The mean injury severity scale score was 25.6, and 76% were wounded by an improvised explosive device. Ultrasound was useful for confirming (23%) or excluding (63%) the suspected diagnosis made in the clinical assessment. It also helped obtain a diagnosis that had not been considered for 3% of casualties and was responsible for a major change in procedure or therapy in 4%. Ultrasound altered the surgical priority in 43% of cases. For 30% of cases, US permitted surgery to be temporarily delayed to prioritize another more urgent casualty. CONCLUSION: Ultrasound is a valuable tool for the management of mass casualties by improving treatment and triage, especially when surgical resources are limited. In some situations, US can also correct a diagnosis or improve prehospital therapeutic choices. Field medical teams should be trained to integrate US into their prehospital protocols. LEVEL OF EVIDENCE: Case series (no criterion standard), level V.

Background: The present paper describes three cases where ER-REBOA® was used with partial aorta occlusion (AO), by performing a partial resuscitative endovascular balloon occlusion of the aorta or pREBOA, in an austere pre-hospital military environment.In addition, because no specific REBOA algorithm for pre-hospital environment exists yet, this paper seeks to fill this gap, proposing a new pragmatic REBOA algorithm. Methods: Belgian Special Operations Surgical Team applied REBOA in three patients according to a decisional algorithm, based on the MIST acronym used for trauma patients. Only 3 ml, in the first instance, was inflated in the balloon to get AO. The balloon was then progressively deflated, and reperfusion was tracked through changes of end-tidal carbon dioxide (EtCO2). Results: Systolic blood pressure (SBP) before ER-REBOA® placement was not higher than 60 mmHg. However, within the first 5 min after AO, SBP improved in all three cases. Due to the aortic compliance, a self-made pREBOA was progressively achieved while proximal SBP was raising with intravenous fluid infusion. Afterwards, during deflation, a steep inflection point was observed in SBP and EtCO2. Conclusions: ER-REBOA® is suitable for use in an austere pre-hospital environment. The MIST acronym can be helpful to select the patients for which it could be beneficial. REBOA can also be performed with pREBOA in a dynamic approach, inflating only 3 mL in the balloon and using the aortic compliance. Furthermore, while proximal SBP can be convenient to follow the occlusion, EtCO2 can be seen as an easy and interesting marker to follow the reperfusion.

The purpose of the study was to determine appropriate diagnostic, therapeutic and rehabilitation treatments of patients with military-related craniocereberal trauma. We have examined 180 male patients: 100 participant of operations in the Democratic Republic Afghanistan (1979-1989) and 80 - participants of conflict in the east of Ukraine (from 2014 until present) with military-related craniocereberal trauma of varying severity. We used clinical-neurological, instrumental (craniography of skull, magnetic resonance imaging, ultrasonic doppler sonography of the main vessels of the head and neck), biochemical, statistical methods of a research, and also questionnaire scale SF-36. It was found that the quality of life of patients with military-related craniocereberal trauma depends on the severity of the wound and the period after trauma. In the early period after military-related craniocereberal trauma of light or average severity, the psychological components are more strongly manifested. Patients with severe military-related craniocereberal trauma have serious physical, psychological and social problems at different periods after trauma. The results of the research show that the quality of life depends on the severity of functional disorders and have impact on adaptive potential of the organism.

BACKGROUND: Resuscitative endovascular balloon occlusion of the aorta (REBOA) is used to mitigate bleeding and sustain central aortic pressure in the setting of shock. The ER-REBOA™ catheter is a new REBOA technology, previously reported only in the setting of civilian trauma and injury care. The use of REBOA in an out-of-hospital setting has not been reported, to our knowledge. METHODS: We present a case series of wartime injured patients cared for by a US Air Force Special Operations Surgical Team at an austere location fewer than 3km (5-10 minutes' transport) from point of injury and 2 hours from the next highest environment of care-a Role 2 equivalent. RESULTS: In a 2-month period, four patients presented with torso gunshot or fragmentation wounds, hemoperitoneum, and class IV shock. Hand-held ultrasound was used to diagnose hemoperitoneum and facilitate 7Fr femoral sheath access. ER-REBOA balloons were positioned and inflated in the aorta (zone 1 [n = 3] and zone 3 [n = 1]) without radiography. In all cases, REBOA resulted in immediate normalization of blood pressure and allowed induction of anesthesia, initiation of whole-blood transfusion, damage control laparotomy, and attainment of surgical hemostasis (range of inflation time, 18-65 minutes). There were no access- or REBOArelated complications and all patients survived to achieve transport to the next echelon of care in stable condition. CONCLUSION: To our knowledge, this is the first series to demonstrate the feasibility and effectiveness of REBOA in modern combat casualty care and the first to describe use of the ER-REBOA catheter. Use of this device by nonsurgeons and surgeons not specially trained in vascular surgery in the out-of-hospital setting is useful as a stabilizing and damage control adjunct, allowing time for resuscitation, laparotomy, and surgical hemostasis.

PURPOSE: Injured Syrian patients are commonly transferred to local hospitals and field clinics immediately after being injured. Since February 2011, more than 2,000 injured Syrian patients have been transferred to and treated in northern Israeli medical centers. The aim of the present study was to evaluate the epidemiology and general nature of the injuries, with special attention to maxillofacial (MF) injuries. PATIENTS AND METHODS: The medical files of all injured Syrian patients who were treated in 2 major medical centers in northern Israel from December 2012 through December 2015 were reviewed. Computerized data were collected and analyzed based on the cause of injury, anatomic location, Injury Severity Score (ISS) at admission, hospitalization duration, and duration in the intensive care unit. RESULTS: The study cohort included 227 patients (204 male [90%], 23 female [10%]; mean age, 24.5 ± 11 yr). The median calculated ISS was 20.6 ± 13.9. The mean interval from injury to recorded admission time was 86.37 hours. Fifty patients had MF injuries (22%). Of these, 45 were adults (44 men, 6 women). Patients' age ranged from 16 to 27.3 years. The mean interval from injury to time of admission was 24 hours and the mean ISS on admission was 24.5 ± 12.7, which was significantly higher than the overall ISS (median, 24.5 vs 16; P = .005). CONCLUSION: Several features observed in the present study had a direct effect on treatment quality and success. Those features included delay from injury to hospital admission; lack of body armor protection, including helmets, which explained the high prevalence of MF injuries; and the multiple sites of injury.

Blast-related mild traumatic brain injury (mTBI) is a common injury of the Iraq and Afghanistan Wars. Research has suggested that blast-related mTBI is associated with chronic white matter abnormalities, which in turn are associated with impairment in neurocognitive function. However, findings are inconsistent as to which domains of cognition are affected by TBI-related white matter disruption. Recent evidence that white matter abnormalities associated with blast-related mTBI are spatially variable raises the possibility that the associated cognitive impairment is also heterogeneous. Thus, the goals of this study were to examine (1) whether mTBI-related white matter abnormalities are associated with overall cognitive status and (2) whether white matter abnormalities provide a mechanism by which mTBI influences cognition. Ninety-six Operation Enduring Freedom/Operation Iraqi Freedom (OEF/OEF) veterans were assigned to one of three groups: no-TBI, mTBI without loss of consciousness (LOC) (mTBI-LOC), and mTBI with LOC (mTBI + LOC). Participants were given a battery of neuropsychological tests that were selected for their sensitivity to mTBI. Results showed that number of white matter abnormalities was associated with the odds of having clinically significant cognitive impairment. A mediation analysis revealed that mTBI + LOC was indirectly associated with cognitive impairment through its effect on white matter integrity. These results suggest that cognitive difficulties in blast-related mTBI can be linked to injury-induced neural changes when taking into account the variability of injury as well as the heterogeneity in cognitive deficits across individuals.

INTRODUCTION: Injuries to the innominate artery are rare, but potentially fatal. Early diagnosis and treatment may avoid life-threatening complications. Endovascular surgery often has lower morbidity and mortality rates than conventional surgery. CLINICAL CASE: We reported the case of a 28-year-old Yemenite soldier who presented with a shrapnel-related chest puncture wound following a shell explosion in Djibouti causing a 5 mm pseudoaneurysm of the innominate artery without associated complications. After medical repatriation to France, the pseudoaneurysm was treated by endovascular exclusion using a covered stent. DISCUSSION: Endovascular treatment of supra-aortic trunk lesions is an alternative to surgery with fewer postoperative complications, but long-term follow-up is lacking.

Point-of-care ultrasonography has been recognized as a relevant and versatile tool in Special Operations Forces (SOF) medicine. The Special Operator Level Clinical Ultrasound (SOLCUS) program has been developed specifically for SOF Medics. A number of challenges, including skill sustainment, high-volume training, and quality assurance, have been identified. Potential solutions, including changes to content delivery methods and application of tele-ultrasound, are described in this article. Given the shift in operational context toward extended care in austere environments, a curriculum adjustment for the SOLCUS program is also proposed.

Purpose To determine whether functional outcomes of veterans who sustained combat-related mild traumatic brain injury (TBI) are associated with scalar metrics derived from diffusion-tensor (DT) imaging at their initial postdeployment evaluation. Materials and Methods This HIPAA-compliant retrospective study was approved by the institutional review board, and the requirement to obtain informed consent was waived. From 2010 to 2013, initial postdeployment evaluation, including clinical assessment and brain magnetic resonance (MR) examination with DT imaging, was performed in combat veterans who sustained mild TBI while deployed. Outcomes from chart review encompassed initial postdeployment clinical assessment as well as later functional status, including evaluation of occupational status and health care utilization. Scalar diffusion metrics from the initial postdeployment evaluation were compared with outcomes by using multivariate analysis. Veterans who did and did not return to work were also compared for differences in clinical variables by using t and χ(2) tests. Results Postdeployment evaluation was performed a mean of 3.8 years after injury (range, 0.5-9 years; standard deviation, 2.5 years). After a mean follow-up of 1.4 years (range, 0.5-2.5 years; standard deviation, 0.8 year), 34 of 57 veterans (60%) had returned to work. Return to work was associated with diffusion metrics in multiple regions of white matter, particularly in the left internal capsule and the left frontal lobe (P = .02-.05). Overall, veterans had a mean of 46 health care visits per year during the follow-up period (range, 3-196 visits per year; standard deviation, 41 visits per year). Cumulative health care visits over time were inversely correlated with diffusion anisotropy of the splenium of the corpus callosum and adjacent parietal white matter (P < .05). Clinical measures obtained during initial postdeployment evaluation were not predictive of later functional status (P = .12-.8). Conclusion Differences in white matter microstructure may partially account for the variance in functional outcomes among veterans who sustained combat-related mild TBI. (©) RSNA, 2016.

STUDY DESIGN: A retrospective case series of UK victims of blast injury. OBJECTIVE: To identify the injury patterns in the spine caused by under-vehicle blast, and attempt to derive the mechanism of those injuries. SUMMARY OF BACKGROUND DATA: The Improvised Explosive Device has been a feature of recent conflicts with frequent attacks on vehicles, leading to devastating injuries. Vehicle design has evolved to reduce the risk of injury to occupants in underbody blast, where the device detonates beneath the vehicle. The mechanism of spinal injury in such attacks is not well understood; understanding the injury mechanism is necessary to produce evidence-based mitigation strategies. METHODS: A Joint Theatre Trauma Registry search identified UK victims of blast between 2008 and 2013. Each victim had their initial scan reviewed to classify spinal fractures. RESULTS: Seventy-eight victims were identified, of whom 53 were survivors. There were a total of 284 fractures, including 101 thoracolumbar vertebral body fractures and 39 cervical spine fractures. Most thoracolumbar fractures were wedge compression injuries. Most cervical spine fractures were compression-extension injuries.The most common thoracic and lumbar body fractures in this group suggest a flexed posture at the time of injury. Most cervical spine fractures were in extension, which might be compatible with the head having struck another object. CONCLUSION: Modifying the seated posture might reduce the risk of thoracolumbar injury, or allow the resulting injury patterns to be controlled. Cervical spine injuries might be mitigated by changing vehicle design to protect the head. LEVEL OF EVIDENCE: N/A.

Injuries to the spinal column in combat casualties sustained during the conflicts in Iraq and Afghanistan are common, and the highest in reported wartime history. High-energy blast mechanisms from improved explosive devices have resulted in complex polytrauma and injury patterns, which are often markedly different from those injuries encountered in civilian trauma. Herein, we review the most current literature with regard to the distinct types of combat-related spine injuries/concomitant comorbidities sustained in Operations Enduring Freedom, Iraqi Freedom and New Dawn.

AIMS: In the recent Iraq and Afghanistan conflicts, survival rates from complex battlefield injuries have continued to improve. The resulting war-related wounds are challenging, with confounding issues making assessment of tissue perfusion subjective and variable. This review discusses the utility of intraoperative fluorescence angiography, and its usefulness as an objective tool to evaluate the perfusion of tissues in the face of complex war-related injuries. METHODS: A retrospective review of all war-related traumatic and reconstructive cases employing intraoperative indocyanine green laser angiography (ICGLA) was performed. Data analyzed included indication for use, procedure success/failure rates, modifications performed, and perfusion-related complications. Anatomical regions assessed were extremity, head and neck, truncal, and intra-abdominal viscera. The endpoint of specific interest involved the decision for additional debridement of poorly perfused tissue, as based on the ICGLA findings. RESULTS: Over a 3-year period, this study examined 123 extremity soft tissue flaps, 41 extremity injuries including amputation and/or amputation revision cases, 13 craniofacial flaps, and 9 truncal/abdomen/gastrointestinal cases in which ICGLA was utilized to assess tissue perfusion and viability. A total of 35 (18.8%) of cases employing ICGLA required intraoperative modifications to address perfusion-related issues. CONCLUSIONS: Intraoperative fluorescent angiography is an objective, useful tool to assess various war-related traumatic injuries. This study expands on prior cited indications for ICGLA to include (1) guiding debridement in heavily contaminated wounds, (2) providing improved assessment of avulsion soft tissue injuries, (3) allowing for rapid detection of vascular and/or microvascular compromise in soft tissue and osseous flap reconstructions, (4) reducing and preventing perfusion-related complications in trauma, amputation closures, and reconstruction procedures, (5) contributing to better outcomes in certain complex orthopedic and composite tissue injuries, and (6) enabling improved postoperative wound and reconstruction assessment in those cases of perfusion-related issues that arise within a delayed setting.
