TNP Trauma Nursing Process Rienforces a systemic and standardized approach to trauma nursing care and skills using an intergeated approach to trauma teamwork, communication and collabration Trauma Leading cause of death ages 1-44 approx one person every 3 min 00:02 01:33 brief Planned teamwork event designated to form a team, designate team roles and responsibilities, establish climate goals, and engage in team short and long term goals huddle Ideally convened prior to trauma arrival for the purpose of solving a problem and regaining situational awareness Debrief to explain the purposes and methods of a completed procedure to a participant trauma wound or injury to living tissue caused by a extrinsic agent laws of physics When the intensity of the applied energy exceeds the capacity of tissue resistance, trauma occurs kinetic energy energy of motion Biomechanics The science concerned with the internal and external forces acting on the human body and the effects produced by these forces. Kinematics study of pure motion mechanical energy How external energy forces in the environment are transferred to the body Newton's first law of motion Explains that a body at rest will remain at rest and a body in motion will remain in motion unless acted by an object 00:02 01:33 Newton's Second Law Force = mass x acceleration Newton's Third Law For every action force there is an equal and opposite reaction force resulting kinetic energy energy of body in motion penetrating trauma injury caused by an object that passes through the skin or other body tissues Bullet related trauma ... Thermal Trauma An injury that results in the burning or freezing of tissues blast trauma Occurs when energy in the form of light heat and sound is released rapidly Rollover collisions with ejection Ejection from the vehicle significantly increases the probability of fatal injury kenetic energy KE Speed increases energy by the square of the velocity and can influence the extent of injury. Velocity and KE are positively correlated with destruction KE increases velocity, although velocity is relative it is the projectile KE that causes damage by transferring energy to the tissue Cavitation The formation of cavities in an organ or tissue Explosion in an enclosed space Increase in pressure relative to the explosion that occurs in open environment, the increases pressure compounds the blast effects and potentially increases internal and external injury severity Primary Survey A Across the room assessment for uncontrolled bleeding, Airway and alertness with simultaneous cervical stabilization Primary Survey B Breathing and ventilation Primary Survey C circulation and control of bleeding Primary survey D Disability (neurological status) Primary Survey E Exposure and environmental control Primary survey F Full set of vitals and family presence Primary Survey g Get monitoring devices and give comfort Secondary survey H History & head to toe assessment Secondary survey I Inspect posterior surfaces Secondary Survey J Just keep reevaluating A-I Secondary Survey L Labs T&S ABG lactate Secondary survey M Monitor for cardiac rhythm and rate assessment Secondary survey N Nasogastric or orogastic tube consideration
