Diagnosing Myocardial Contusion after Blunt Chest Trauma
A myocardial contusion refers to a bruise of the cardiac muscle, the severity of which can vary depending on the severity of the injury and when the injury occurs. It is a major cause of rapid death which happens after blunt chest trauma and should be suspected at triage in the emergency department. We demonstrated that suspected myocardial contusion patients who have normal electrocardiograms ...
متن کاملPlastic Wave Propagation Model for Perforation of Metallic Plates by Blunt Projectiles
In this paper, a six-stage interactive model is presented for the perforation of metallic plates using blunt deformable projectiles when plastic wave propagation in both target and projectile is considered. In this analytical model, it is assumed that the projectile and target materials are rigid – plastic linear work hardened. The penetration of the projectile into the target is divided into s...
متن کاملOn the mechanics of fracture in monoliths and multilayers from low-velocity impact by sharp or blunt-tip projectiles
The propagation of cracks in layered glass from low-velocity impact of sharp or spherical tip projectiles is observed using high-speed photography. Tests are also carried out to determine the threshold impact energy for chipping in glass blocks and subsurface crack instability in an edge-supported glass plates. The results identify the median and subsurface radial crack systems as the prime dam...
متن کاملThree Dimensional Simulation of Impact Response of Glass Fiber Reinforced Aluminium Laminates for Conical and Blunt Nose Projectiles
Fiber-reinforced polymeric composites are used widely due to their unique properties of light weight, stiffness and high strength weight ratio. During processing and servicing, the composite materials undergoes delamination, and petalling. Computational model was constructed for finite element modeling to reflect material purpose under impact load and relevant material properties were taken. In...
متن کامل[Myocardial contusion and pericardial effusion after blunt chest trauma].
We have read with great interest the recent and interesting contribution by Dr. Francia et al. about a case of late cardiac tamponade due to myocardial contusion. We would like to make certain observations regarding a similar case that we have recently treated. A 70-year-old woman came to our emergency department after having undergone the Heimlich maneuver because of choking. Upon admittance, ...
