Hemorrhage is the leading cause of trauma-related deaths, partly because early diagnosis of the severity of blood loss is difficult. Assessment of hemorrhaging patients is difficult because current clinical tools provide measures of vital signs that remain stable during the early stages of bleeding due to compensatory mechanisms. Consequently, there is a need to understand and measure the total integration of mechanisms that compensate for reduced circulating blood volume and how they change during ongoing progressive hemorrhage...

Computer-assisted surgical (CAS) planning tools are available for craniofacial surgery, but are usually based on computer-aided design (CAD) tools that lack the ability to detect the collision of virtual objects (i.e., fractured bone segments). We developed a CAS system featuring a sense of touch (haptic) that enables surgeons to physically interact with individual, patient-specific anatomy and immerse in a three-dimensional virtual environment. In this study, we evaluated initial user experience with our novel system compared to an existing CAD system...

Synthetic bone cements are commonly used in orthopaedic procedures to aid in bone regeneration following trauma or disease. Polymeric cements like PMMA provide the mechanical strength necessary for orthopaedic applications, but they are not resorbable and do not integrate with host bone. Ceramic cements have a chemical composition similar to that of bone, but their brittle mechanical properties limit their use in weight-bearing applications. In this study, we designed oxidatively degradable, polymeric bone cements with mechanical properties suitable for bone tissue engineering applications...

Desmoid tumor of breast is a rare benign, locally aggressive tumor with a high recurrence rate. It has been associated with scar from previous breast surgery or trauma. Especially in breast cancer patients with previous operation history, it may simulate recurrent breast cancer clinically and radiologically. We presented multimodality imaging findings (ultrasound, computed tomography, magnetic resonance imaging and positron emission tomography/computed tomography) of chest wall desmoid tumor mimicking recurrent breast cancer in a 38-year-old patient with a history of left modified mastectomy...

Venipuncture is one of the most commonly done medical procedures. We report a unique case of a 23-year-old young male who presented with features suggestive of inflammatory arthritis. The symptoms, which initially started on the right side, also involved the other side after a few weeks. Although the patient's symptoms and signs were simulating inflammatory arthritis, he had atypical features like poor response to anti-inflammatory medicines and normal laboratory parameters. His musculoskeletal ultrasonography was also not suggestive of arthritis...

BACKGROUND: Elbow lateral collateral ligament (LCL) injury may arise after trauma or lateral surgical approaches. The optimal method of rehabilitating the LCL-insufficient elbow is unclear. Therapists often prescribe active motion exercises with the forearm pronated. Recently, overhead exercises have become popular as they may enable gravity to compress the elbow joint, improving stability, although this has not been proved biomechanically. This investigation aimed to quantify the effects of several variables used in LCL injury rehabilitation on elbow stability...

BACKGROUND: Airway management is a crucial skill essential to paramedics and personnel working in Emergency Medical Services and Emergency Departments: Lack of practice, a difficult airway, or a trauma situation may limit the ability of paramedics to perform direct laryngoscopy during cardiopulmonary resuscitation. Videoscope devices are alternatives for airway management in these situations. The ETView VivaSight SL (ETView; ETView Ltd., Misgav, Israel) is a new, single-lumen airway tube with an integrated high-resolution imaging camera...

BACKGROUND: Rapid effective trauma resuscitations (TRs) decrease patient morbidity and mortality. Few studies have evaluated TR care times. Effective time goals and superior human patient simulator (HPS) training can improve patient survivability. OBJECTIVES: The purpose of this study was to compare live TR to HPS resuscitation times to determine mean incremental resuscitation times and ascertain if simulation was educationally equivalent. The study was conducted at San Antonio Military Medical Center, Department of Defense Level I trauma center...

OBJECTIVES: Endotracheal intubation (ETI) is an important skill for all emergency providers; our ability to train and assess our learners is integral to providing optimal patient care. The primary aim of this study was to assess the inter-rater reliability (IRR) and discriminant validity of a novel field ETI assessment tool using a checklist-derived performance score (PS) and critical failure (CF) rate. METHODS: Forty-three participants (18 paramedic students, 11 paramedics, and 14 emergency physicians [EPs]) performed ETI during a simulated trauma scenario on a pseudo-ventilated cadaver...

BACKGROUND: Successful tracheal intubation during general anaesthesia traditionally requires a line of sight to the larynx attained by positioning the head and neck and using a laryngoscope to retract the tongue and soft tissues of the floor of the mouth. Difficulties with intubation commonly arise, and alternative laryngoscopes that use digital and/or fibreoptic technology have been designed to improve visibility when airway difficulty is predicted or encountered. Among these devices, a rigid videolaryngoscope (VLS) uses a blade to retract the soft tissues and transmits a lighted video image to a screen...

BACKGROUND: Effective teamwork is critical in the trauma bay, although there is a lack of consensus related to optimal training for these skills. We implemented in situ trauma simulations with debriefing as a possible training methodology to improve team-oriented skills. METHODS: Focus groups were conducted with multidisciplinary clinicians who respond to trauma activations. The focus group questions were intended to elicit discussion on the clinicians' experiences during trauma activations and simulations with an emphasis on confidence, leadership, cooperation, communication, and opportunities for improvement...

M J Douma, D O'Dochartaigh, P G Brindley
BACKGROUND: Applying manual pressure after hemorrhage is intuitive, cost-free, and logistically-simple. When direct abdominal-pelvic compression fails, clinicians can attempt indirect proximal-external-aortic-compression (PEAC), while expediting transfer and definitive rescue. This study quantifies the sustainability of simulated bi-manual PEAC both immediately on scene and during subsequent ambulance transfer. The goal is to understand when bi-manual PEAC might be clinically-useful, and when to prioritize compression-devices or endovascular-occlusion...

BACKGROUND: Between 30 and 40 % of patients with severe injuries receive treatment at non-trauma centers (under-triage), largely because of physician decision making. Existing interventions to improve triage by physicians ignore the role that intuition (heuristics) plays in these decisions. One such heuristic is to form an initial impression based on representativeness (how typical does a patient appear of one with severe injuries). We created a video game (Night Shift) to recalibrate physician's representativeness heuristic in trauma triage...

Distance learning is expanding and replacing the traditional academic medical settings. Managing trauma patients seems to be a prerequisite skill for medical students. This study has been done to evaluate the efficiency of distance learning on performing the initial assessment and management in trauma patients, compared with the traditional learning among senior medical students. One hundred and twenty senior medical students enrolled in this single-blind quasi-experimental study and were equally divided into the experimental (distance learning) and control group (traditional learning)...

OBJECTIVES: The Accreditation Council for Graduate Medical Education milestones provide a framework of specific interpersonal and communication skills that surgical trainees should aim to master. However, training and assessment of resident nontechnical skills remains challenging. We aimed to develop and implement a curriculum incorporating interactive learning principles such as group discussion and simulation-based scenarios to formalize instruction in patient-centered communication skills, and to identify best practices when building such a program...

The main failure factors of cortical bone are aging or osteoporosis, accident and high energy trauma or physiological activities. However, the mechanism of damage evolution coupled with yield criterion is considered as one of the unclear subjects in failure analysis of cortical bone materials. Therefore, this study attempts to assess the structural response and progressive failure process of cortical bone using a brittle damaged plasticity model. For this reason, several compressive tests are performed on cortical bone specimens made of bovine femur, in order to obtain the structural response and mechanical properties of the material...
