Mechanisms of Injury Blunt Trauma Compression Forces Cells in tissues are compressed and crushed E.g. Spleen Shear Forces Acceleration/Deceleration Injury E.g. Aorta Shearing force = Spectrum from Full thickness tear (Exsanguination) to Partial tear (Pseudoaneurysm) Overpressure Body cavity compressed at a rate faster than the tissue around it, resulting in rupture of the closed space E.g. Plastic bag E.g. in trauma = diaphragmatic rupture, bladder injury 8

Primary Survey Airway and Protection of Spinal Cord Breathing and Ventilation Circulation Disability Exposure and Control of the Environment 12
Slide 13-

Primary Survey Key Principles When you find a problem during the primary survey, FIX IT. If the patient gets worse, restart from the beginning of the primary survey Some critical patients in the Emergency Department may not progress beyond the primary survey 13
Slide 14-

Airway and Protection of Spinal Cord Why first in the algorithm? Loss of airway can result in death in < 3 minutes Prolonged hypoxia = Inadequate perfusion, End-organ damage Airway Assessment Vital Signs = RR, O2 sat Mental Status = Agitation, Somnolent, Coma Airway Patency = Secretions, Stridor, Obstruction Traumatic Injury above the clavicles Ventilation Status = Accessory muscle use, Retractions, Wheezing Clinical Pearls Patients who are speaking normally generally do not have a need for immediate airway management Hoarse or weak voice may indicate a subtle tracheal or laryngeal injury Noisy respirations frequently indicates an obstructed respiratory pattern 14
Slide 15-

Airway Interventions Maintenance of Airway Patency Suction of Secretions Chin Lift/Jaw thrust Nasopharyngeal Airway Definitive Airway Airway Support Oxygen NRBM (100%) Bag Valve Mask Definitive Airway Definitive Airway Endotracheal Intubation In-line cervical stabilization Surgical Crichothyroidotomy 15 Dept. of the Army, Wikimedia Commons Ignis, Wikimedia Commons U.S. Navy photo by Photographer's Mate 2nd Class Timothy Smith, Wikimedia Commons
Slide 16-

Protection of Spinal Cord General Principle: Protect the entire spinal cord until injury has been excluded by radiography or clinical physical exam in patients with potential spinal cord injury. Spinal Protection Rigid Cervical Spinal Collar = Cervical Spine Long rigid spinal board or immobilization on flat surface such as stretcher = T/L Spine Etiology of Spinal Cord Injury (U.S.) Road Traffic Accidents (47%) High energy falls (23%) Clinical Pearls Treatment (Immobilization) before diagnosis Return head to neutral position Do not apply traction Diagnosis of spinal cord injury should not precede resuscitation Motor vehicle crashes and falls are most commonly associated with spinal cord injuries Main focus = Prevention of further injury 16
Slide 17-

C-spine Immobilization Return head to neutral position Maintain in-line stabilization Correct size collar application Blocks/tape Sandbags James Heilman, MD, Wikimedia Commons Paladinsf (flickr) 17
Slide 18-

Breathing and Ventilation General Principle: Adequate gas exchange is required to maximize patient oxygenation and carbon dioxide elimination Breathing/Ventilation Assessment: Exposure of chest General Inspection Tracheal Deviation Accessory Muscle Use Retractions Absence of spontaneous breathing Paradoxical chest wall movement Auscultation to assess for gas exchange Equal Bilaterally Diminished or Absent breath sounds Palpation Deviated Trachea Broken ribs Injuries to chest wall 18
Slide 19-

Identify Life Threatening Injuries Tension Pneumothorax Air trapping in the pleural space between the lung and chest wall Sufficient pressure builds up and pressure to compress the lungs and shift the mediastinum Physical exam Absent breath sounds Air hunger Distended neck veins Tracheal shift Treatment Needle Decompression 2nd Intercostal space, Midclavicular line Tube Thoracostomy 5th Intercostal space, Anterior axillary line Breathing and Ventilation Author unknown, www.meddean.luc.edu/lumenMedEd/medicine/pulmonar/cxr/pneumo1.htm Delldot (wikimedia) 19
Slide 20-

Breathing and Ventilation Hemothorax Blood collecting in the pleural space and is common after penetrating and blunt chest trauma Source of bleeding = Lung, Chest wall (intercostal arteries), heart, great vessels (Aorta), Diaphragm Physical Exam Absent or diminished breath sounds Dullness to percussion over chest Hemodynamic instability Treatment = Large Caliber Tube Thoracostomy 10-20% of cases will require Thoracostomy for control of bleeding Author unknown, http://www.trauma.org/index.php/main/images/C11/ 20
Slide 21-

Breathing and Ventilation Flail Chest Direct injury to the chest resulting in an unstable segment of the chest wall that moves separately from remainder of thoracic cage Typically results from two or more fractures on 2 or more ribs Typically accompanied by a pulmonary contusion Physical exam = paradoxical movement of chest segment Treatment = improve abnormalities in gas exchange Early intubation for patients with respiratory distress Avoidance of overaggressive fluid resuscitation http://images1.clinicaltools.com/images/trauma/flail_chest_wounded.gif Author unknown, http://www.surgical-tutor.org.uk/default-home.htm?specialities/cardiothoracic/chest_trauma.htm~right 21
Slide 22-

Breathing and Ventilation Open Pneumothorax Sucking Chest Wound Large defect of chest wall Leads to rapid equilibration of atmospheric and intrathoracic pressure Impairs oxygenation and ventilation Initial Treatment Three sided occlusive dressing Provides a flutter valve effect Chest tube placement remote to site of wound Avoid complete dressing, will create a tension pneumothorax Middle and bottom images: Author unknown, http://www.brooksidepress.org/Products/OperationalMedicine/DATA/operationalmed/Procedures/TreataSuckingChestWound.htm Author unknown, http://www.trauma.org/index.php/main/image/902/ 22

Slide 25-

Circulation Shock Impaired tissue perfusion Tissue oxygenation is inadequate to meet metabolic demand Prolonged shock state leads to multi-organ system failure and cell death Clinical Signs of Shock Altered mental status Tachycardia (HR > 100) = Most common sign Arterial Hypotension (SBP < 120) Femoral Pulse – SBP > 80 Radial Pulse – SBP > 90 Carotid Pulse – SBP > 60 Inadequate Tissue Perfusion Pale skin color Cool clammy skin Delayed cap refill (> 3 seconds) Altered LOC Decreased Urine Output (UOP < 0.5 mL/kg/hr) 25
Slide 26-

Circulation Types of Shock in Trauma Hemorrhagic Assume hemorrhagic shock in all trauma patients until proven otherwise Results from Internal or External Bleeding Obstructive Cardiac Tamponade Tension Pneumothorax Neurogenic Spinal Cord injury Sources of Bleeding Chest Abdomen Pelvis Bilateral Femur Fractures 26
Slide 27-

Circulation Emergency Nursing Treatment Two Large IV Lines Cardiac Monitor Blood Pressure Monitoring General Treatment Principles Stop the bleeding Apply direct pressure Temporarily close scalp lacerations Close open-book pelvic fractures Abdominal pelvic binder/bed sheet Restore circulating volume Crystalloid Resuscitation (2L) Administer Blood Products Immobilize fractures Responders vs. Nonresponders Transient response to volume resuscitation = sign of ongoing blood loss Non-responders = consider other source for shock state or operating room for control of massive hemorrhage 27
Slide 28-

Circulation Pericardial Tamponade Pericardium or sac around heart fills with blood due to penetrating or blunt injury to chest Beck’s Triad Distended jugular veins Hypotension Muffled heart sounds Treatment Rapid evacuation of pericardial space Performed through a pericardiocentesis (temporizing measure) Open thoracotomy Heart Blood Pericardium Epicardium Aceofhearts1968(Wikimedia) 28

Disability Glasgow Coma Scale Eye Spontaneously opens 4 To verbal command 3 To pain 2 No response 1 Best Motor Response Obeys verbal commands 6 Localizes to pain 5 Withdraws from pain 4 Flexion to pain (Decorticate Posturing) 3 Extension to pain (Decerebrate Posturing) 2 No response 1 Verbal Response Oriented/Conversant 5 Disoriented/Confused 4 Inappropriate words 3 Incomprehensible words 2 No response 1 GCS ≤ 8 Intubate 32
Slide 33-

Disability Key Principles Precise diagnosis is not necessary at this point in evaluation Prevention of further injury and identification of neurologic injury is the goal Decreased level of consciousness = Head injury until proven otherwise Maintenance of adequate cerebral perfusion is key to prevention of further brain injury Adequate oxygenation Avoid hypotension Involve neurosurgeon early for clear intracranial lesions 33
Slide 34-

Disability Cervical Spinal Clearance Patients must be alert and oriented to person, place and time No neurological deficits Not clinically intoxicated with alcohol or drugs Non-tender at all spinous processes No distracting injuries Painless range of motion of neck 34
Slide 35-

Exposure Remove all clothing Examine for other signs of injury Injuries cannot be diagnosed until seen by provider Logroll the patient to examine patient’s back Maintain cervical spinal immobilization Palpate along thoracic and lumbar spine Minimum of 3 people, often more providers required Avoid hypothermia Apply warm blankets after removing clothes Hypothermia = Coagulopathy Increases risk of hemorrhage 35
