Chapter 55: Trauma Copyright © 2009 Wolters Kluwer Health | Lippincott Williams & Wilkins Statistics on Trauma • Second to heart disease as the leading cause of death • Motor vehicle accidents are leading cause of injury in the U.S. • 1/3 of all patients are admitted, with a mean hospital stay of 5 days. • Intentional injuries (gunshot injuries, suicides, hangings) • Unintentional injuries (MVA, falls, burns) Copyright © 2009 Wolters Kluwer Health | Lippincott Williams & Wilkins Mechanism of Injury • Involves a description of the events, persons, and objects involved at the scene of the injury • Provides the health care provider with an idea of the extent of damage involved • Also gives the health care provider of an idea of the time between the injury and arrival of first responders • Ask about environmental factors such as the temperature, whether rain/snow/ice increased the skidding (therefore the acceleration) Copyright © 2009 Wolters Kluwer Health | Lippincott Williams & Wilkins Types of Injuries BLUNT TRAUMA • No break in the skin • More life-threatening as not as obvious and diagnosis is more difficult • Types include acceleration, deceleration, shearing, crushing, compressive injuries • Size of vehicle and occupant as well as position PENETRATING TRAUMA • Wounds caused by impalement or an object passing through tissue • Severity is due to organ or tissue damage • High-velocity vs. lowvelocity weapons – High velocity: highpowered rifle – Low velocity: ski pole, knife stab wound Copyright © 2009 Wolters Kluwer Health | Lippincott Williams & Wilkins Blunt and Penetrating Traumas in MVA Copyright © 2009 Wolters Kluwer Health | Lippincott Williams & Wilkins Prehospital Management • Mechanism of injury (from patient or bystanders) • Primary survey (ABCDs) – Airway, Breathing, Circulation, Discover (bleeding) – Head and neck stabilization • Secondary survey – Full body assessment from head to toe for any other injuries – SAMPLE (Signs/Symptoms, Allergies, Medications, Past Medical History, Last Meal, Events leading up to accident) Copyright © 2009 Wolters Kluwer Health | Lippincott Williams & Wilkins Question Which of the following is true regarding prehospital care of the trauma victim? A. Positive outcomes are ensured if the patient reaches a level trauma I care hospital within 2 to 3 hours. B. More interventions should be provided if the transport time is short. C. Transport of a patient to a trauma center is associated with a lower mortality rate and better outcomes. D. Transportation to a facility for stabilization initially is imperative. Copyright © 2009 Wolters Kluwer Health | Lippincott Williams & Wilkins Answer C. Transport of a patient to a trauma center is associated with a lower mortality rate and better outcomes. Rationale: Trauma patients do have better outcomes if they are admitted to a level I trauma center. Patients were initially transported to a closer, but not necessarily a level I, institution for stabilization, but this has proven not to be as effective in decreasing the mortality rate. Positive outcomes are ensured if the patient reaches a level trauma I center within “the golden hour” after injury. More interventions should be provided if the transport time is longer, not shorter. Copyright © 2009 Wolters Kluwer Health | Lippincott Williams & Wilkins The Primary Survey: Initial Nursing Assessment and Management ASSESSMENT NURSING INTERVENTIONS Airway Air flow to the lungs maintained Jaw thrust, chin lift; removal of airway obstruction; suctioning; insertion of oral or nasal airway; ETT Breathing Respiratory rate, SaO2, breath sounds normal range; trachea is midline. Oxygen delivery systems; bag-valve ventilation, then ventilator; treat tension pneumothorax Circulation Apical pulse, BP; capillary refill; peripheral pulses; ECG; obvious external bleeding Hemorrhage control; IV therapy and/or blood transfusions; treatment of life-threatening conditions (cardiac tamponade) Disability LOC and pupillary check (direct/consensual response) Exposure Look for bleeding Stop any obvious bleeding with pressure if not already done. Monitor fractures, penetrating wounds. Copyright © 2009 Wolters Kluwer Health | Lippincott Williams & Wilkins Primary Assessment • After airway and breathing have been stabilized, monitor and correct hypovolemia. • Signs and symptoms of hypovolemia include pale skin, diaphoresis, tachycardia, and hypotension. The patient may also be confused and disoriented. • A large-bore IV has been started by the first responders so infusion of fluid should be run rapidly. • A urinary catheter is inserted to measure hourly urine outputs. • Take the patient’s temperature, especially if the accident occurred outside. Use warm blankets and IV fluids to correct temp. Copyright © 2009 Wolters Kluwer Health | Lippincott Williams & Wilkins Intravenous Fluid Resuscitation Choices Copyright © 2009 Wolters Kluwer Health | Lippincott Williams & Wilkins Question According to research, which of the following is the best fluid replacement in the early stages of hypovolemia in a trauma patient? A. NSS B. D5W C. Lactated Ringer’s (LR) D. Hypertonic saline Copyright © 2009 Wolters Kluwer Health | Lippincott Williams & Wilkins Answer D. Hypertonic saline Rationale: Although isotonic solutions such as NSS and lactated Ringer’s have been used in the past, research has shown that hypertonic saline restores cardiac function more quickly with smaller volumes. The recommended amount can be as little as 4 mL/kg. Hypertonic saline recruits fluid from the interstitial space and results in a rapid increase in intracellular pressure, which improves hemodynamics. Copyright © 2009 Wolters Kluwer Health | Lippincott Williams & Wilkins Secondary and Tertiary Surveys SECONDARY SURVEY TERTIARY SURVEY • More comprehensive head-to-toe assessment • Assessment of ABCDEs • Additional historical information • Review of lab data and diagnostic studies – Significant others – Past medical records • Diagnostic studies • Another head-to-toe assessment • An injury found within 24 hours is not counted as a “missed” injury. Copyright © 2009 Wolters Kluwer Health | Lippincott Williams & Wilkins Other Solutions That Could Be Administered to Increase Volume • Colloids • Blood products – Increase the “pulling” power of fluid. Makes fluid stay in the vascular tree. – Types include albumin, dextran, and hetastarch. – Increase volume and oxygenation – Risk of infection and reactions • Autotransfusions • Blood substitutes Copyright © 2009 Wolters Kluwer Health | Lippincott Williams & Wilkins Question O+ blood that is not cross-matched can be administered to a man or a postmenopausal woman. A. True B. False Copyright © 2009 Wolters Kluwer Health | Lippincott Williams & Wilkins Answer A. True Rationale: In an emergency, O+ blood can be administered to a man or postmenopausal woman without crossmatching, and O- blood can be used for a woman of childbearing age.

Copyright © 2009 Wolters Kluwer Health | Lippincott Williams & Wilkins Question A patient is admitted to the ICU after a MVA. He has multiple fractures but no soft or hollow tissue organ damage. Which of the following would change this patient’s status to a more life-threatening prognosis? A. An avulsion B. Pelvic fracture C. Femoral fracture D. An open fracture Copyright © 2009 Wolters Kluwer Health | Lippincott Williams & Wilkins Answer B. Pelvic fracture Rationale: Pelvic fractures and traumatic amputations are more serious than other injuries. An avulsion is a skin flap and not a complete fracture. A femoral fracture (increased bleeding) and an open fracture (bleeding and infection risk) increase complications but would not necessarily increase the mortality rate.
