Available in PDF, EPUB and Kindle. Book excerpt: In Operations Enduring Freedom and Iraqi Freedom, explosions accounted for 81% of all injuries; this is a higher casualty percentage than in any previous wars. Blast wave overpressure has recently been associated with varying levels of traumatic brain injury in soldiers exposed to blast loading. Presently, the injury mechanism behind primary blast brain injury is not well understood due to the complex interactions between the blast wave and the human body. Despite these limitations in the understanding of head injury thresholds, head kinematics are often used to predict the overall potential for head injury. The purpose of this study was to investigate head kinematics, and predict injury from a range of simulated blast loads at varying standoff distances and differing heights of bursts. The validated Generator of body data multi-body human surrogate model allows for numerical kinematic data simulation in explicit finite element method fluid structure interaction blast modeling. Two finite element methods were investigated to simulate blast interaction with humans, an enhanced blast uncoupled method, and an Arbitrary Lagrangian Eularian fully coupled method. The enhanced blast method defines an air blast function through the application of a blast pressure wave, including ground reflections, based on the explosives relative location to a target; the pressures curves are based on the Convention Weapons databases. LBE model is efficient for parametric numerical studies of blast interaction where the target response is the only necessary result. The ALE model, unlike classical Lagrangian methods, has a fixed finite element mesh that allows material to flow through it; this enables simulation of large deformation problems such as blast in an air medium and its subsequent interaction with structures. The ALE model should be used when research into a specific blast scenario is of interest, since this method is more computationally expensive. The ALE method can evaluate a blast scenario in more detail including: explosive detonation, blast wave development and propagation, near-field fireball effects, blast wave reflection, as well as 3D blast wave interaction, reflection and refraction with a target. Both approaches were validated against experimental blast tests performed by Defense Research and Development Valcartier and ConWep databases for peak pressure, arrival time, impulse, and curve shape. The models were in good agreement with one another and follow the experimental data trend showing an exponential reduction in peak acceleration with increasing standoff distance until the Mach stem effect reached head height. The Mach stem phenomenon is a shock front formed by the merging of the incident and reflected shock waves; it increases the applied peak pressure and duration of a blast wave thus expanding the potential head injury zone surrounding a raised explosive. The enhanced blast model was in good agreement with experimental data in the near-field, and mid-field; however, overestimated the peak acceleration, and head injury criteria values in the far-field due to an over predicted pressure impulse force. The ALE model also over predicted the response based on the head injury criteria at an increased standoff distance due to smearing of the blast wave over several finite elements leading to an increased duration loading. According to the Abbreviated Injury Scale, the models predicted a maximal level 6 injury for all explosive sizes in the near-field, with a rapid acceleration of the head over approximately 1 ms. There is a drastic exponential reduction in the insult force and potential injury received with increasing standoff distance outside of the near-field region of an explosive charge.

Available in PDF, EPUB and Kindle. Book excerpt: In many parts of the world, civilians and peacekeepers are exposed to potentially serious injury from blasts and explosions. Providing insight into the trauma thresholds for blast injury is necessary for the development of blast protection equipment and identification and subsequent treatment of blast injury. [Phillips, 1988] Blast injury can be categorized as primary, secondary, tertiary, quaternary and quinernary, corresponding to different aspects of the blast loading and injury mechanisms. Primary blast injury occurring in the lungs is of importance, since lung injury results in one of the highest rate of blast mortality. Much of the existing blast injury data was obtained from animal testing with sheep and subsequently extrapolated to humans using scaling techniques. More recently, mathematical, experimental and numerical models have been developed and employed to investigate blast injury. In this study, a detailed finite element model of a sheep thorax and human thorax (developed at the University of Waterloo) was used to predict primary blast lung injury based on a range of blast loading conditions.

Available in PDF, EPUB and Kindle. Book excerpt: This book introduces BlastSim - a physics-based simulation platform to model and simulate suicide bombing events. The BlastSim software is designed to test, analyze, and validate the results of different explosive and injury model combinations under various conditions with different sets of parameters, such as explosive and crowd formation characteristics, blockage and human shielding effects, fragmentation and shrapnel, and the bomber's position in 2- and 3-dimensional environments. The suicide bombing event can also be re-created for forensic analysis. The number of fatalities and injured after a suicide bombing event can be predicted using this software with 91% accuracy. The assessment of an explosion's effect on a crowd can lead to better management of disasters, triage of patients, locating blast victims under the debris, development of protective gear, and safe distance recommendations to reduce casualties.

Available in PDF, EPUB and Kindle. Book excerpt: A formal training program with theoretical and practical components is essential for all emergency medical personnel involved in providing care for critically injured patients. Communication, effective first aid, and on time transportation to a health center play a major role in improving quality of care for critically injured patients. Using life experience examples, participants in the study emphasized the importance of each factor on the delivery of quality care for critically injured patients. Recommendations based on the study findings included two main categories. The first category illustrated recommendations to stakeholders, and the second category reflected recommendations for further study. Stakeholders in this study included healthcare leaders in Afghanistan, healthcare professionals involved in providing health care in Afghanistan, and local people in Afghanistan. The modified van Kaam method in the qualitative phenomenological study involved conducting semistructured interviews, which were audio-taped and transcribed. The rationale for using the phenomenological approach in the qualitative study was to describe in-depth experiences of health care professionals. Moustakas (1994) modified van Kaam method explored the lived experiences and perceptions of 17 doctors and nurses relating to emergency trauma care for critically injured patients. Data analysis revealed important factors that could enhance the quality of prehospital care for civilian casualties of landmine and unexploded ordnance (UXO) blast injuries in Afghanistan. The four major themes that emerged from participants responses to interview questions included communication, formal training for emergency medical personnel, transportation to a higher-level center, and quality of prehospital care.

This book was released on 2005-10-13 with total page 484 pages. Available in PDF, EPUB and Kindle. Book excerpt: Substantialfundamental workhas been undertaken inthe different aspects of impact biomechanics over the past three decades. Much of this has been motivated and undertaken bythe automotive industry intheirefforts to improve transport safety. More recently, however, it has become app- ent that themultidisciplinary synergies which are realisedby interactions between engineers, scientists and clinical practitioners will ultimately lead to a greater understanding of the complex interacting phenomena withinthe human bodyafter it has sustained an impact. In turn, this greater depth of knowledge will provide more fundamentalinsights into the analysis, d- gnosis, treatment and prevention ofimpact injuries across a broader sp- trum of accident environments. Thescienti?c focus of this IUTAM symposium istoaddress those t- ics that are centrally important to the biomechanics ofimpact. These can be groupedinto those that are concerned with the different causes of - cidents (e. g., transport, occupational and sports injuries), themechanics - volvedinaccident analysis (e. g., accident investigation, computational m- elling techniques), the different types of resulting traumatic injuries (incl- ing musculoskeletal, organ, spinal and head injuries), methods of asse- ing the extent of injury (e. g., injury assessment, injury criteria, constitutive laws for human tissue), and providing protection during an impact (e. g., injury prevention, energy absorption materials, and safety devices).

Book excerpt: Few human activities demand or deserve as much attention of the citizens of a nation as the array of man-made and natural “environmental” threats faced by the soldiers and other warriors defending the nation – those that pose the risk of disease, injury, combat wounds, and even death. This book is the Army’s first detailing research in computational physiology models and highlighting pivotal research. It outlines the extent to which basic and applied biomedical scientists, clinicians, modelers, and others strive to understand the extent of these threats, and provide intellectual and materiel options to mitigate these risks. This book summarizes major Army research efforts to quantify and model military relevant physiology. These chapters highlight the translation of this research into useful predictive tools. The tools are of importance to medical planners, materiel developers, commanders, and in many cases, every soldier. These chapters detail the experimental basis for many of the predictive tools that are currently in use. This book is written for military clinicians, and medical researchers who may be reasonably expected to explain some of the background, as well as those who will extend the research. Many people will find this book interesting because it details research on topics that affect everyone in everyday life, including how we sleep, eat, and exercise, as well as more specific topics such as the effects of caffeine on performance, risks associated with laser pointers, and even Army blast models that have influenced safety thresholds for car airbag deployments.

Available in PDF, EPUB and Kindle. Book excerpt: Experience with animals exposed in a variety of above and below ground structures during full-scale field operations at the Nevada Test Site in 1953, 1955 and 1957 were reviewed. The data were assembled and summarized to illustrate the nature of the blast-induced problems of significance in protective shelters, "open" as well as "closed". Potential hazards were related to the following: various patterns of variation in environmental pressure; translational events associated with transient, high-velocity winds, ground shock and gravity involving the impact of energized inanimate objects on the one hand the the consequences of whole-body displacement on the other; non-line-of-site thermal phenomena including hot objects and rapidly moving hot, dust- laden air and debris; and dust, in the respirable size range, sufficiently high in concentration even in "closed" shelters as to warrant design measures to minimize or eliminate the occurrence of small particulates whether arising from wall spalling or otherwise. Tentative biological criteria, conceived to help assess human hazards from blast-related phenomena, were presented. Relevant data from the literature and on- going research in environmental medicine were set forth to aid the reader in appreciating how the criteria were formulated, what information was extrapolated from animal data, and wherein "best estimates" were employed. "State-of-the-art" concepts were noted to emphasize areas in which more thinking and research must continue if more refined, complete and adequate criteria are to be forthcoming for assessing man's response to blast-induced variation in his immediate environment.

This book was released on 2014-02-04 with total page 215 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the past decade, few subjects at the intersection of medicine and sports have generated as much public interest as sports-related concussions - especially among youth. Despite growing awareness of sports-related concussions and campaigns to educate athletes, coaches, physicians, and parents of young athletes about concussion recognition and management, confusion and controversy persist in many areas. Currently, diagnosis is based primarily on the symptoms reported by the individual rather than on objective diagnostic markers, and there is little empirical evidence for the optimal degree and duration of physical rest needed to promote recovery or the best timing and approach for returning to full physical activity. Sports-Related Concussions in Youth: Improving the Science, Changing the Culture reviews the science of sports-related concussions in youth from elementary school through young adulthood, as well as in military personnel and their dependents. This report recommends actions that can be taken by a range of audiences - including research funding agencies, legislatures, state and school superintendents and athletic directors, military organizations, and equipment manufacturers, as well as youth who participate in sports and their parents - to improve what is known about concussions and to reduce their occurrence. Sports-Related Concussions in Youth finds that while some studies provide useful information, much remains unknown about the extent of concussions in youth; how to diagnose, manage, and prevent concussions; and the short- and long-term consequences of concussions as well as repetitive head impacts that do not result in concussion symptoms. The culture of sports negatively influences athletes' self-reporting of concussion symptoms and their adherence to return-to-play guidance. Athletes, their teammates, and, in some cases, coaches and parents may not fully appreciate the health threats posed by concussions. Similarly, military recruits are immersed in a culture that includes devotion to duty and service before self, and the critical nature of concussions may often go unheeded. According to Sports-Related Concussions in Youth, if the youth sports community can adopt the belief that concussions are serious injuries and emphasize care for players with concussions until they are fully recovered, then the culture in which these athletes perform and compete will become much safer. Improving understanding of the extent, causes, effects, and prevention of sports-related concussions is vitally important for the health and well-being of youth athletes. The findings and recommendations in this report set a direction for research to reach this goal.

Available in PDF, EPUB and Kindle. Book excerpt: The first edition of this publication was aimed at defining the current concepts of trauma induced coagulopathy by critically analyzing the most up-to-date studies from a clinical and basic science perspective. It served as a reference source for any clinician interested in reviewing the pathophysiology, diagnosis, and management of the coagulopathic trauma patient, and the data that supports it. By meticulously describing the methodology of most traditional as well as state of the art coagulation assays the reader is provided with a full understanding of the tests that are used to study trauma induced coagulopathy. With the growing interest in understanding and managing coagulation in trauma, this second edition has been expanded to 46 chapters from its original 35 to incorporate the massive global efforts in understanding, diagnosing, and treating trauma induced coagulopathy. The evolving use of blood products as well as recently introduced hemostatic medications is reviewed in detail. The text provides therapeutic strategies to treat specific coagulation abnormalities following severe injury, which goes beyond the first edition that largely was based on describing the mechanisms causing coagulation abnormalities. Trauma Induced Coagulopathy 2nd Edition is a valuable reference to clinicians that are faced with specific clinical challenges when managing coagulopathy.
