Understanding how energy forces affect the human body is useful for better anticipating effects of trauma on a person What are common MOIs that result in trauma blunt, penetrating, blast What injuries are expected in each stage of a blast (explosion) Primary (direct blast effects) - pulmonary barotrauma, tympanic membrane rupture, abdominal hemorrhage/perforation, globe rupture, mild TBI Secondary (projectiles) - penetrating or blunt injuries, eye penetration Tertiary (propulsion of body onto hard surface) - blunt/penetrating injury, fracture, traumatic amputation, closed/open TBI Quaternary (heat/fume/combustion) - burns, crush injury, asthma, COPD, angina, hyperglycemia, hypertension Quinary (hazardous materials) - depends on agent (bacteria, radiation, chemical etc) Why is it important to use a systemic approach to the initial assessment of a trauma patient? To maximize outcomes and reduce the risk of undiscovered injuries. What is included in the preparation for a trauma patient? Activate the Trauma Team and assign roles Prepare the room/equipment Don PPE Consider safety threats Decontamination What information is obtained in the general impression overall status and identification of hemorrhage; identify all life threatening injuries; APVU

What does the A-J mnemonic stand for? A - airway/alertness B - breathing/ventilation C - circulation, control of hemorrhage D - disability (neuro status) E - exposure and environmental control F - full set of vitals/family presence G - get adjusts/give comfort L - labs M - monitor cardiac status N - nasogastric/orogastric O - oxygenation P - pain H - history/head to toe I - inspect posterior J - just keep reevaluating What does alertness include in airway assessment? APVU When an intervention is taken during the primary survey, what must the nurse do after the intervention? reassess What are componants of secondary survey? history head to toe assessment inspect posterior surfaces reassessment What should nurse reevaluate? all aspects of the primary and secondary assessments V - vitals I - injuries/interventions P - primary survey P - pain What are the differences in ventilation, diffusion and perfusion? ventilation - mechanical process of breathing diffusion - movement of gases (higher to lower concentration) perfusion - movement of blood through circulatory system What are possible causes of airway obstruction in the trauma patient? altered consciousness - tongue falling posteriorly into oropharynx, blood/vomit/fluids unable to be cleared maxillofacial trauma - edema, secretions, bleeding, dislodeged teeth/dentures neck/larangeal trauma - vascular injuries resulting in hematomas obese patients - increased fat deposition What interventions address airway obstruction? suction jaw thrust insert airway

What is the difference between an airway adjunct and a definitive airway? airway adjunct - work by stenting open the upper airway - nasopharyngeal - oropharyngeal (unresponsive/no gag reflex) - extraglottic (Supra or Retro "king tube") definitve airway - tube securely placed in the trachea with cuff inflated below vocal cords -ett tube What is the difference between normoxia and hyperoxia? Why does it matter? normoxia - normal o2 in blood - Pa02 60-120 Hyperoxia -high o2 level in blood - Pa02 >120 too much o2 can contribute to poor outcomes -lung damage - ↓ CO/ ↑ vascular resistance -CNS toxicity - twitching, blurred vision, convulsions etc -increased mortality - especially in TBI, cardiac arrest, stroke, sepsis What is the most common type of shock in trauma patients? What are possible interventions to manage uncontrolled external hemorrhage? hypovolemic shock - hemorrhage control (internal, external, burns) - restore circulating volume What are causes of obstructive shock? hypoperfusion due to obstruction in either of the great vessels of the heart resulting in ↓ CO -cardiac tamponade -tension hemothorax -tension pneumothorax -venous air embolism What types of shock may occur after a spinal cord injury where there is a loss of sympathetic innervation below the level of injury? distributive shock - neurogenic shock resulting from loss of SNS control of vascular tone - leads to venous and arterial vasodilation - causes brady and ↓ CO What are some possible interventions for cardiogenic shock? emergent stabilization - inotropic support (improve contractility) - controlled fluid bolus (improve preload) goal directed therapy - antidysrhythmic medication - treatment of underlying cause What is damage control resuscitation? Rapid restoration of hemostasis - control hemorrhage - administer blood - prevention of trauma triad of death 2 strategies - hypotensive and hemostatic resuscitation Why is it critical to rapidly recognize and intervene during compensatory stage of shock? the window to intervene is narrow
