RESUMO
BACKGROUND: The relationship between acute combat-related traumatic injury (CRTI) to coronary flow reserve (CFR) and subclinical cardiovascular risk have not been examined and was the primary aim of this study. METHODS AND RESULTS: UK combat veterans from the ADVANCE cohort study (UK-Afghanistan War 2003-14) with traumatic limb amputations were compared to injured non-amputees and to a group of uninjured veterans from the same conflict. Subclinical cardiovascular risk measures included fasted blood atherogenic index of plasma (AIP), triglyceride-glucose index (TyG; insulin resistance), the neutrophil-lymphocyte ratio (NLR) and high-sensitivity C-reactive protein (hs-CRP; vascular inflammation), body mass index (BMI) and visceral fat volume (dual-energy X-ray absorptiometry) and 6-min walk distance (6MWD; physical performance). The subendocardial viability ratio (SEVR), to estimate CFR, was calculated using arterial pulse waveform analysis (Vicorder device). In total 1144 adult male combat veterans were investigated, comprising 579 injured (161 amputees, 418 non-amputees) and 565 uninjured men. AIP, TyG, NLR, hs-CRP, BMI, total body fat and visceral fat volume were significantly higher and the SEVR and 6MWD significantly lower in the amputees versus the injured-non-amputees and uninjured groups. The SEVR was lowest in those with above knee and multiple limb amputations. CRTI (ExpB 0.96; 95% CI 0.94-0.98: p < 0.0001) and amputation (ExpB 0.94: 95% CI 0.91-0.97: p < 0.0001) were independently associated with lower SEVR after adjusting for age, rank, ethnicity and time from injury. CONCLUSION: CRTI, traumatic amputation and its worsening physical deficit are associated with lower coronary flow reserve and heightened subclinical cardiovascular risk.

Osteomyelitis is a serious complication associated with war-related limb injuries requiring complicated treatment regimens and management. Few reports have been published from the Middle-East and North-Africa regions about the microbial aetiology of osteomyelitis caused by war injuries. The aim of this review is to collect published data about the microbiology of osteomyelitis in war-related injuries in the region and to derive targeted treatment regimens to manage these serious and limb-threatening infections. A thorough literature search was done using six search engines for pertinent articles. Articles with a minimum of five cases of osteomyelitis from war wounds, citation of microbial aetiology and mention of the timing of cultures obtained in relation to injury were included. Nine studies that met the eligibility criteria were included, involving 1644 patients and a total of 2332 cultures. Gram-negative bacteria were isolated from 1184 cultures, and Gram-positive bacteria were identified from 1148 cultures. Antibiotic coverage should be tailored for Gram-negative organisms in the early stages and Gram-positives in the chronic phase, respectively, with broader coverage reserved for critically ill patients. There is a dire need for further and larger studies about osteomyelitis from war injuries for targeted treatment.

During the Greco-Italian War (World War II [WWII], 1940-1941), an Italian field hospital was set up in Sinanaj, Albania. The hospital's military surgeons carefully collected information about the characteristics and management of patients with war-related injuries. In 1942, they published a detailed report, with a section dedicated to the management of war-related head injuries. The aim of this report is to analyze that section, to describe the characteristics and neurosurgical management of war-related head injuries, and to depict the status of war neurosurgery in the Royal Italian Army during WWII. The analysis revealed that, during the Greco-Italian War (November 1940-April 1941), 149 patients with war-related head injuries were admitted to the Sinanaj hospital, and 48 patients underwent surgery. Head injuries were caused by bomb fragments in 126 patients, bullets in 5 patients, and other causes (falls from height, vehicle accidents, or rock fragments) in 18 patients. Six patients (12.5%) died after surgery. Before surgery, patients underwent resuscitation with blood transfusions and fluid. Preoperatively, a plain head radiograph was usually acquired to locate metallic and bone fragments. The surgical technique consisted of craniotomy or craniectomy, aggressive debridement of metallic and bone fragments, and watertight dural closure. Surgical drainage, overall aseptic technique, serial spinal taps, and perioperative antibiotics were used to prevent infections. The surgical aims and technique used by the Italian surgeons for the management of head injuries were similar to those of the Allied surgeons during WWII. Operative mortality was also comparable. Although the surgical technique for war-related head injuries has evolved since WWII, many aspects of the technique used by the Italian and Allied surgeons during WWII are still in the standard of care today.

BACKGROUND: In case of a warm fresh whole blood transfusion on the battlefield, the blood donation usually occurs just after a combat phase and often after several days on the fields. To explore the hemostatic capacity of such blood, we analyzed the blood of volunteers attending the commando course of the French Navy, considering this course as an experimental model, placing them into the same physiological conditions as those faced by deployed fighters. METHODS: Venous blood was collected at the beginning of the course, mimicking their baseline status, and a second time 6 weeks later, from the remaining candidates, during the actual commando training, mimicking the stress conditions. For each candidate, we observed the differences between the two blood samples. RESULTS: Of the 112 men that attended the first day of the course, only 17 remained 6 weeks later. In the second blood samples, we noted significant increased leucocytes and platelets counts and significant decreased hematocrit and hemoglobin levels. Thrombin generation assays showed significantly lower normalized peak heights (-31%), lower normalized endogenous thrombin potential values (-29%), and lower velocity index (-35%). Normalized lag time and time to peak did not differ. Viscoelastometric testing revealed a significant increasing in clot firmness as assessed by maximum amplitude and amplitude at 6 minutes. The clot speed was significantly increased. CONCLUSION: This work brings new data on coagulation during prolonged and considerable physical exercise. No obvious deleterious modification of hemostatic properties was observed. The decrease of the endogenous thrombin potentials may reflect a better ability to control the thrombin generation once started. Altogether, these results suggest that this blood could suit well a hemorrhagic war-injured patient. LEVEL OF EVIDENCE: Prospective observational cohort study, Level III.

BACKGROUND: Surgical site infections (SSIs) are well-recognized complications after exploratory laparotomy for abdominal trauma; however, little is known about SSI development after exploration for battlefield abdominal trauma. We examined SSI risk factors after exploratory laparotomy among combat casualties. METHODS: Military personnel with combat injuries sustained in Iraq and Afghanistan (June 2009 to May 2014) who underwent laparotomy and were evacuated to participating US military hospitals were included. Log-binominal regression was used to identify SSI risk factors. RESULTS: Of 4,304 combat casualties, 341 patients underwent a total of 1,053 laparotomies. Abdominal SSIs were diagnosed in 49 patients (14.4%): 8% with organ space SSI, 4% with deep incisional SSI, and 4% with superficial SSIs (4 patients had multiple SSIs). Patients with SSIs had more colorectal (p < 0.001), small bowel (p = 0.010), duodenum (p = 0.006), pancreas (p = 0.032), and abdominal vascular injuries (p = 0.040), as well as prolonged open abdomen (p = 0.004) and more infections diagnosed before the SSI (or final exploratory laparotomy) versus non-SSI patients (p < 0.001). Sustaining colorectal injuries (risk ratio [RR], 3.20; 95% confidence interval [CI], 1.58-6.45), duodenum injuries (RR, 6.71; 95% CI, 1.73-25.58), and being diagnosed with prior infections (RR, 10.34; 95% CI, 5.05-21.10) were independently associated with any SSI development. For either organ space or deep incisional SSIs, non-intra-abdominal infections, fecal diversion, and duodenum injuries were independently associated, while being injured via an improvised explosive device was associated with reduced likelihood compared with penetrating nonblast (e.g., gunshot wounds) injuries. Non-intra-abdominal infections and hypotension were independently associated with organ space SSIs development alone, while sustaining blast injuries were associated with reduced likelihood. CONCLUSION: Despite severity of injuries and the battlefield environment, the combat casualty laparotomy SSI rate is relatively low at 14%, with similar risk factors and rates reported following severe civilian trauma. LEVEL OF EVIDENCE: Epidemiological, level III.

BACKGROUND: Abdominal injuries historically account for 13% of battlefield surgical procedures. We examined the occurrence of exploratory laparotomies and subsequent abdominal surgical site infections (SSIs) among combat casualties. METHODS: Military personnel injured during deployment (2009-2014) were included if they required a laparotomy for combat-related trauma and were evacuated to Landstuhl Regional Medical Center, Germany, before being transferred to participating US military hospitals. RESULTS: Of 4304 combat casualties, 341 (7.9%) underwent laparotomy. Including re-explorations, 1053 laparotomies (median, 2; interquartile range, 1-3; range, 1-28) were performed with 58% occurring within the combat zone. Forty-nine (14.4%) patients had abdominal SSIs (four with multiple SSIs): 27 (7.9%) with deep space SSIs, 14 (4.1%) with a deep incisional SSI, and 12 (3.5%) a superficial incisional SSI. Patients with abdominal SSIs had larger volume of blood transfusions (median, 24 versus 14 units), more laparotomies (median, 4 versus 2), and more hollow viscus injuries (74% versus 45%) than patients without abdominal SSIs. Abdominal closure occurred after 10 d for 12% of the patients with SSI versus 2% of patients without SSI. Mesh adjuncts were used to achieve fascial closure in 20.4% and 2.1% of patients with and without SSI, respectively. Survival was 98% and 96% in patients with and without SSIs, respectively. CONCLUSIONS: Less than 10% of combat casualties in the modern era required abdominal exploration and most were severely injured with hollow viscus injuries and required massive transfusions. Despite the extensive contamination from battlefield injuries, the SSI proportion is consistent with civilian rates and survival was high.

BACKGROUND: In gunshot and shell fragment injuries to the hip joint, orthopedic intervention includes wound assessment and care, osteosynthesis of fractures, and avoiding of infection and osteoarthritis. Individuals injured in the Syrian civil war were frequently transferred to the authors' institution in neighboring city. Orthopedic trauma exposures were determined in approximately 30% of these patients. The aim of this study was to evaluate the outcomes of the patients with secondary hip arthritis due to prior gunshot and shell fragment (shrapnel) injuries who underwent primary total hip arthroplasty. METHODS: This retrospective study reviewed 26 patients (24 males, 2 females) who underwent hip arthroplasty due to prior gunshot and shell fragment injuries from November 2013 to January 2019. For all patients, the Harris Hip Score (HHS) was evaluated preoperatively and after surgery. RESULTS: Mean age was 31.5 (range, 19-48) years. The mean preoperative HHS was 52.95 points, and the mean postoperative HHS was 79.92 points at the final follow-up after surgery. Patients with shell fragment injuries to the hip joint had higher infection rates, but it is not statistically significant. CONCLUSIONS: An anatomic reduction of the fracture may not be possible in these cases as a result of significant bone and/or cartilage loss. Total hip arthroplasty can be done after gunshot- and shell fragment-related posttraumatic arthritis. It is an effective treatment choice to reduce pain and improve function, but the surgeon must be very careful because of high rate of infection.

BACKGROUND: Surgical management of trauma in the last 20 years has evolved in parallel with the military's experience in the current conflicts. Therapies such as widespread tourniquet use, empiric administration of fresh frozen plasma, and airborne intensive care units had been viewed skeptically but are now common practice. There is an opportunity to expand the envelope of care even further through similarly innovative approaches and varied avenues of research. RESULTS: As the molecular biology of trauma is elucidated, research methodologies must also be developed to capitalize on innovative approaches to resuscitation. Blood component therapy and control of bleeding remain as the fundamental concepts in trauma care. The inflammo-immune response to injury, however, plays an increasingly recognized role in recovery of organ function. Perhaps the inflammatory cascade of trauma can be manipulated to extend the treatment envelope of at risk trauma patients.In trauma, the additional challenge of delivering effective treatment, often required very early after injury, necessitates the development of treatments to be implemented on the front lines of trauma care that are cost-effective, portable, and environmentally stable. Future conflicts may not offer ready access to high-level surgical care; therefore, resuscitative therapies will be needed for wounded service members because they are evacuated to the surgeon. Manipulation of the inflammatory response to trauma may offer a solution. As our understanding of the immune response continues to develop, the potential for improved outcomes for the wounded expands. CONCLUSION: A review of basic concepts in immunology is necessary to appreciate any potential impact of immunotherapeutic approaches to trauma and inflammation. An overview of current options will focus on outcome benefits of available therapies and suggest possible areas for future investigation. Quantitative approaches will leverage basic science to identify high-yield strategies to improve care of the injured combatant. LEVEL OF EVIDENCE: Review, level III.

BACKGROUND: Noncompressible hemorrhage remains a high-mortality injury, and aortic balloon occlusion poses limitations in terms of distal ischemic injury. Our hypothesis was that a retrievable Rescue stent would confer improved outcome over aortic balloon occlusion. METHODS: A three-tier, retrievable stent graft was laser welded from nitinol and polytetrafluoroethylene to provide rapid thoracic and abdominal coverage with an interval bare metal segment to preserve visceral flow. Anesthetized swine had injury of the thoracic or abdominal aorta followed by balloon occlusion or a Rescue stent. A 1-hour long damage-control phase with blood repletion was used to simulate the prolonged interval between injury and repair, especially in the battlefield setting. Following the damage-control phase, the balloon or stent were retrieved followed by vascular repair and recovery to 48 hours. Animals were compared in terms of hemodynamics, blood loss, neurophysiologic spinal cord ischemia, ischemic organ injury, and survival. RESULTS: Despite antegrade hemorrhage control, balloon occlusion averaged 3.5 L of retrograde hemorrhage, loss of visceral perfusion, and permanent spinal cord ischemia by neurophysiology in six of seven animals. After permanent repair, all balloon occlusion animals died with only a single short term (5 hours) survivor. Conversely, Rescue stent animals revealed rapid hemorrhage control (in under 2 minutes) whether the injury was thoracic or abdominal with improved hemodynamics, preserved visceral flow, reduced spinal cord ischemia, negligible histologic organ injury and survival to end of study in all abdominal injured animals (n = 6) and four of six thoracic injured animals, with two deaths related to arrhythmia. CONCLUSION: Compared with aortic balloon occlusion, a Rescue stent offers superior hemorrhage control and survival by virtue of reduced ischemic injury and direct control of the hemorrhagic injury. The Rescue stent may become a useful tool for damage control, especially on the battlefield where definitive repair presents logistical challenges.

BACKGROUND: Post-traumatic acute kidney injury has occurred in every major military conflict since its initial description during World War II. To ensure the proper treatment of combat casualties, early detection is critical. This study therefore aimed to investigate combat-related post-traumatic acute kidney injury in recent military conflicts, used machine learning algorithms to identify clinical and biomarker variables associated with the development of post-traumatic acute kidney injury, and evaluated the effects of post-traumatic acute kidney injury on wound healing and nosocomial infection. METHODS: We conducted a retrospective clinical cohort review of 73 critically injured US military service members who sustained major combat-related extremity wounds and had collected injury characteristics, assayed serum and tissue biopsy samples for the expression of protein and messenger ribonucleic acid biomarkers. Bivariate analyses and random forest recursive feature elimination classification algorithms were used to identify associated injury characteristics and biomarker variables. RESULTS: The incidence of post-traumatic acute kidney injury was 20.5%. Of that, 86% recovered baseline renal function and only 2 (15%) of the acute kidney injury group required renal replacement therapy. Random forest recursive feature elimination algorithms were able to estimate post-traumatic acute kidney injury with the area under the curve of 0.93, sensitivity of 0.91, and specificity of 0.91. Post-traumatic acute kidney injury was associated with injury severity score, serum epidermal growth factor, and tissue activin A type receptor 1, matrix metallopeptidase 10, and X-C motif chemokine ligand 1 expression. Patients with post-traumatic acute kidney injury exhibited poor wound healing and increased incidence of nosocomial infections. CONCLUSION: The occurrence of acute kidney injury in combat casualties may be estimated using injury characteristics and serum and tissue biomarkers. External validations of these models are necessary to generalize for all trauma patients.

BACKGROUND: Shock Index (SI) has been used to predict the need for massive transfusion (MT) and emergency surgical procedures (ESP) in civilian trauma. We hypothesize that SI can reliably identify combat trauma patients that will require MT and ESP when applied to the resource-constrained, combat environment. METHODS: A retrospective review was performed within the Department of Defense Trauma Registry (2008-2016). SI was calculated using heart rate and systolic blood pressure on arrival to the initial facility with surgical capabilities. A threshold value of 0.8 was used to stratify patients into two groups (Group I, SI < 0.8; and Group II, SI ≥ 0.8). The need for MT, ESP, and mortality was compared. Regression analyses were conducted to determine the independent association of SI with MT and ESP. RESULTS: A total of 4008 patients were included. The mean age of the patients was 25.5 y, and the majority were predominately male (98%). Mechanisms of injury were blunt and blast injury (62%), penetrating injury (36.7%), and burn injury (0.5%). Overall, 77% of patients (n = 3070) were stratified to Group I, and 23% of patients (n = 938) were stratified to Group II, by SI. Group II patients had a significantly greater need for MT (8.4% versus 0.4%) and ESP (30.7% versus 6.5%), both P < 0.001. Regression analysis controlling for age, gender, Injury Severity Score, and Glasgow Coma Score confirmed that SI ≥ 0.8 was an independent risk factor for both MT and need for ESPs (P < 0.001). CONCLUSIONS: SI is a significant predictor of the need for MT and ESPs in the military trauma population, representing a simple and potentially potent tool for triage and prediction of resource consumption in the resource-limited, austere setting.

OBJECTIVES: The aim of this study was to explore possible long-term negative health effects of injuries sustained by modern weaponry. SETTING: The study was conducted in Gaza's main hospital, Al-Shifa Hospital. PARTICIPANTS: During the last 10 to 15 years, thousands of civilian Palestinians in Gaza have survived numerous military incursions, but with war-related traumatic injuries caused by explosive weapons. It is unclear to which extent the injuries sustained by such modern weaponry may increase survivors' risks of negative long-term health effects and serious illness. We have reported mechanisms and severity of injury, demographics and psychosocial status among 254 Palestinian patients in Gaza with war-related extremity amputations. Among the same amputees, subgroups of patients presented a variety of alarming symptoms and findings. 94 patients received further diagnostic clinical exploration, radiology imaging and clinical chemistry laboratory tests at the main clinical centre in Gaza, the Al-Shifa Hospital. RESULTS: Nine out of ten of the referred patients were young (median 31.5 years) males (88/94, 92.6%). Ultrasound imaging revealed that 19 of 90 patients (20%) had fatty liver infiltration, 3 patients had lung nodules and 10 patients had lung atelectasis on chest CT. Twelve had remaining shrapnel(s) in the chest, five patients had shrapnel(s) in the abdomen and one in the scrotum. We found shrapnel(s) in the amputation stumps of 26 patient's amputated limbs, while 8 patients had shrapnel in the non-amputated limb. Three patients had liver lesions. Nineteen patients had elevated liver enzymes, 32 patients had elevated erythrocyte sedimentation rate and 12 were anaemic. Two patients tested positive for hepatitis C virus and three were positive for hepatitis B virus (HBV). One of the 19 patients with fatty liver tested positive for HBV. Two of the patients with fatty liver infiltration had elevated glycatedhaemoglobin levels and confirmed diabetes mellitus type II. CONCLUSION: Nearly half (44, 8%) had remaining metal fragments from explosives of unknown composition harboured in various parts of their bodies. All patients identified with lesions and nodules are being followed up locally. As of now, we cannot anticipate the long-term health consequences of living with metal residuals from modern explosive weapons embedded in body organs and tissue.

BACKGROUND: According to the Joint Theater Trauma Registry, 26% to 33% of war casualties develop acute respiratory distress syndrome (ARDS), with high mortality. Here, we aimed to describe ARDS incidence and severity among patients evacuated from war zones and admitted to French intensive care units (ICUs). METHODS: We performed an observational retrospective multicentric review of all patients evacuated from war zones and admitted to French ICUs between 2003 and 2018. Our analysis included all medical and trauma patients developing ARDS according to the Berlin definition. We evaluated ARDS incidence, and determined ARDS severity from arterial blood gas analysis. Analyzed parameters included invasive ventilation duration, ARDS treatments, ICU stay length, and 30-day and 90-day mortalities. RESULTS: Among 141 included patients (84% military; median age, 30 years), 57 (42%) developed ARDS. Acute respiratory distress syndrome was mild in 13 (22%) patients, moderate in 24 (42%) patients, and severe in 20 (36%) patients. Evacuation occurred in less than 26 hours for 32 war casualties, 17 non-war-related trauma patients, and 8 medical patients. Among severe trauma patients, median Injury Severity Score was 34, and Abbreviated Injury Scale thorax was 3. Upon French ICU admission, median partial pressure of oxygen in arterial blood/inspirated fraction of oxygen ratio was 241 [144-296]. Administered ARDS treatments included intubation (98%, n = 56), protective ventilation (87%, n = 49), neuromuscular blockade (76%, n = 43), prone position (16%, n = 9), inhaled nitric oxide (10%, n = 6), almitrine (7%, n = 7), and extracorporeal life support (4%, n = 2). Median duration of invasive ventilation was 13 days, ICU stay was 18 days, 30-day mortality was 14%, and 90-day mortality was 21%. CONCLUSION: Acute respiratory distress syndrome was frequent and severe among French patients evacuated from war theaters. Improved treatment capacities are needed in the forward environment-for example, a specialized US team can provide extracorporeal life support for highly hypoxemic war casualties. LEVEL OF EVIDENCE: Prognostic and epidemiological study, level III.

BACKGROUND: Traumatic injuries, such as those from combat-related activities, can lead to complicated clinical presentations that may include dysphagia. METHODS: This retrospective observational database study captured dysphagia-related information for 215 US military service members admitted to the first stateside military treatment facility after sustaining combat-related or combat-like traumatic injuries. A multidimensional relational database was developed to document the nature, course, and management for dysphagia in this unique population and to explore variables predictive of swallowing recovery using Bayesian statistical modeling and inferential statistical methods. RESULTS: Bayesian statistical modeling revealed the importance of maxillofacial fractures and soft tissue loss as primary predictors of poor swallowing outcomes. The presence of traumatic brain injury (TBI), though common, did not further complicate dysphagia outcomes. A more detailed examination and rating of videofluoroscopic swallow studies from a subset of 161 participants supported greater impairment for participants with maxillofacial trauma and no apparent relationship between having sustained a TBI and swallow functioning. CONCLUSION: These analyses revealed that maxillofacial trauma is a stronger indicator than TBI of dysphagia severity and slower or incomplete recovery following combat-related injuries. LEVEL OF EVIDENCE: Therapeutic/Care Management study, level IV.

BACKGROUND: Intravenous ketamine is commonly used for pain management in the civilian prehospital setting. Several studies have evaluated its effectiveness in the military setting. To date, there has been no report reviewing the published data on the use of ketamine in this context. The objective of this systematic review was to analyze the content and quality of published data on the use of ketamine for prehospital pain management in military trauma. METHODS: The MEDLINE database was searched for studies on ketamine use in combat prehospital settings, at point of injury or during evacuation, published between 2000 and 2019. The systematic review was conducted following PRISMA guidelines, and the protocol was registered on PROSPERO (CRD42019115728). Civilian reports and case series lacking systematic data collection were excluded. RESULTS: Eight studies were included with 2029 casualties receiving ketamine. All but one were American reports from Afghanistan and Iraq conflicts. Studies implied retrospective cohorts or prospective observational analysis. Ketamine use rose from 3.9% during the period preceding its addition to the Tactical Combat Casualty Care guidelines in 2012 to 19.8% thereafter. It was the most common analgesic administered (up to 52% of casualties) in one of the studies. Ketamine was more likely given during tactical medical evacuation when no analgesic was provided at the point of injury. The median total intravenous dose was 50 mg. Pain intensity decreased from moderate or severe to mild or none, sometimes after only one dose. In one study, ketamine administration during tactical evacuation was associated with increased systolic blood pressure as opposed to morphine. Incoherent speech, extremity movements, and hallucinations were the main adverse events reported. CONCLUSION: Published data on ketamine use in military trauma are rare and heterogeneous. Though, all studies tend to strengthen the belief in the efficacy and safety of ketamine when given at 50-mg to 100-mg intravenous for prehospital analgesia in combat casualties. LEVEL OF EVIDENCE: Systematic Review, Level IV.

The 2012 study Death on the battlefield (2001-2011) by Eastridge et al.1 demonstrated that 7.5% of the prehospital deaths caused by potentially survivable injuries were due to external hemorrhage from the cervical region. The increasing use of Tactical Combat-Casualty Care (TCCC) and other medical interventions have dramatically reduced the overall rate of combat-related mortality in US forces; however, uncontrolled hemorrhage remains the number one cause of potentially survivable combat trauma. Additionally, the use of personal protective equipment and adaptations in the weapons used against US forces has caused changes in the wound distribution patterns seen in combat trauma. There has been a significant proportional increase in head and neck wounds, which may result in difficult to control hemorrhage. More than 50% of combat wounded personnel will receive a head or neck wound. The iTClamp (Innovative Trauma Care Inc., Edmonton, Alberta, Canada) is the first and only hemorrhage control device that uses the hydrostatic pressure of a hematoma to tamponade bleeding from an injured vessel within a wound. The iTClamp is US Food and Drug Administration (FDA) approved for use on multiple sites and works in all compressible areas, including on large and irregular lacerations. The iTClamp's unique design makes it ideal for controlling external hemorrhage in the head and neck region. The iTClamp has been demonstrated effective in over 245 field applications. The device is small and lightweight, easy to apply, can be used by any level of first responder with minimal training, and facilitates excellent skills retention. The iTClamp reapproximates wound edges with four pairs of opposing needles. This mechanism of action has demonstrated safe application for both the patient and the provider, causes minimal pain, and does not result in tissue necrosis, even if the device is left in place for extended periods. The Committee on TCCC recommends the use of the iTClamp as a primary treatment modality, along with a CoTCCC-recommended hemostatic dressing and direct manual pressure (DMP), for hemorrhage control in craniomaxillofacial injuries and penetrating neck injuries with external hemorrhage.

INTRODUCTION: Individuals with persistent symptoms after mild traumatic brain injury (mTBI) often have auditory complaints. In this study, we used the auditory brainstem response (ABR) to determine whether cochlear synaptopathy could explain auditory symptoms. METHODS: 69 adult military service members with mTBI and 25 adults without brain injury (NCT01611194 and NCT01925963) completed pure-tone audiometry, ABR, and central auditory processing tests. All participants were male, ages 21-50. RESULTS: 37/69 mTBI participants had measurable hearing loss, while another 20%-30% had hearing complaints or tinnitus. While mTBI participants with measurable hearing loss had reduced wave I and III amplitude and decreased III-V interpeak latency, those with no measurable hearing loss did not significantly differ from controls on any ABR parameter. Those with measurable hearing loss were also more likely to have abnormal central auditory processing. mTBI participants with no measurable hearing loss but who reported hearing concerns had some ABR findings (III-V interpeak latency, I and V amplitudes, V/I amplitude ratio) more like the measurable hearing loss mTBI group than normative controls. CONCLUSION: Cochlear synaptopathy may have contributed to some of the auditory impairment in service members with mTBI with measurable hearing loss. However, these results are likely confounded by cochlear hair cell damage.
