Blunt Trauma
Question | Answer |
---|---|
A body in motion will stay in motion unless acted upon by an outside force. | Inertia. |
Energy can neither be created nor destroyed. It is only changed from one form to another. | Conservation of energy. |
Energy in motion. Double weight =double energy. Speed is the greatest factor! | Kinetic energy. |
Emphasizes the importance of rate at which an object changes speed. (Acceleration or deceleration) | Force. |
Indirect injury to underlying structures, transmission of energy into the body, tearing muscles, vessels and bone, rupture of solid organs. | Closed injury. |
Open injury. Direct injury to underlying structures. | Penetrating. |
Events of impact in mvc. | Vehicle collision. Body collision. Organ collision. Secondary collision (objects inside vehicle strike occupant) |
Reduce blunt chest trauma but causes hand, forearm and facial injuries. | Airbags. |
Events of an explosion. | Pressure wave. Structure collapse. Blast wind. Burns. Projectiles. Personal displacement. |
Blast injury phases. | Primary-heat of explosion. Secondary-trauma caused by projectiles. Tertiary-personal displacement and structure collapse. |
Blast injuries | Ruptured organs. Hearing loss. Lungs. Diaphragm rupture. Penetrating wounds. Burns. |
Crush injuries | Damage caused by great force to soft tissue and bones. Tissue stretching and compression. Extended pressure results in anaerobic metabolism distal to compression. Toxins build. Hemorrhage. |
Care for prolonged crush injuries. | Sodium bicarb-reduces acidosis. Dopamine-improve kidney function. Morphine-pain management. Longer than 45 mins, push bicarb and calcium before release. |
