OpeningCase Thoracic Trauma
Opening Case • You are dispatched at 1656 for a “car vs. train” accident in a rural area • En route you are told by first responders that the patient was an unrestrained driver of a truck and was ejected • They also tell you he is currently awake and alert; they already have him “boarded”
SICK? Sick or Not-yet-sick? Why? or NOT YET SICK?
Case (continued) • Upon arrival you find a 60-year-old male with the following physical examination findings: • SKIN: Pale, warm, dry • HEENT: Abrasions, contusions to face • CHEST: Crepitus to upper chest, lungs hard to auscultate (obese), denies SOB • BACK: c/o pain
Assessment • What should be your course of treatment? • How should this patient be transported?
Introduction • Trauma to thorax can cause a patient to deteriorate quickly
The Deadly Dozen • The lethal six(identified in the primary survey) • The hidden six(identified in the secondary survey)
The Lethal Six 1. Airway obstruction 2. Tension pneumothorax 3. Cardiac tamponade 4. Massive hemothorax 5. Open pneumothorax 6. Flail chest
The Hidden Six 1. Thoracic aortic disruption 2. Tracheobronchial disruption 3. Myocardial contusion 4. Traumatic diaphragmatic tear 5. Esophageal disruption 6. Pulmonary contusion
Epidemiology • Incidence • Major cause of chest trauma
Applied Anatomy and Physiology Review • 12 ribs • False ribs • Floating ribs • Neurovascular bundle • Hemithorax • Visceral and parietal pleura • Mediastinum • Ligamentum arteriosum
Blunt Trauma • Shearing forces • Compression injuries • Blast injuries
Penetrating Trauma • Impaling Injuries • Projectile Injuries
Scene Survey • Gather information • Severity of injury force • Incident-specific circumstances • Make use of bystanders and law enforcement officers for information
The ABCs • Expose the chest • Look, listen, and feel • Rapidly determine status
Initial Assessment of the Neck • Signs of distress • Inspection • Palpation
Initial Assessment of the Chest • Look • Feel • Listen • Tachypnea • Bradypnea
You witness a car crashing into telephone pole at 65 mph. The driver is awake and disoriented, complaining of shortness of breath and chest pain. The steering wheel is bent and the dashboard is deformed. You cannot feel a radial pulse. You should suspect: A. Pericardial contusion B. Hemothorax C. Rib fractures D. Tension pneumothorax

Specific Thoracic Injuries • Lung and pleural injuries • Pneumothorax and hemothorax • Tension pneumothorax • Open chest wounds
Difficulty breathing that worsens Hypotension Tachycardia Difficulty in performing BVM ventilations that worsens Asymmetrical breath sounds Drop in pulse oximetry Pulses paradoxus JVD Tracheal deviation Chest pain Signs and Symptoms of Tension Pneumothorax
Street Secret • Endotracheal intubation and positive pressure ventilation have a higher potential of turning a simple pneumothorax into a tension pneumothorax • Current recommendations for assisting ventilations using a BVM for adults is to provide NO MORE than 12 breaths per minute
Air Medicine • Monitor for tension pneumothorax carefully
Specific Thoracic Injuries • Simple pneumothorax • Open pneumothorax • Hemothorax
Signs and Symptoms of Massive Hemothorax • Hypotension and obvious shock • Pain • Tachypnea • Low pulse ox reading • Tachycardia • Possible decreased breath sounds • Tracheal deviation or JVD
Specific Thoracic Injuries • Traumatic asphyxia • Pulmonary laceration • Pulmonary contusion
Specific Thoracic Injuries • Tracheobronchial injuries • Causes • Signs and symptoms • Intubation risk?
Specific Thoracic Injuries • Cardiac Injuries • Pericardial Tamponade • When pericardial sac fills with fluid • Hypotension, JVD, Beck’s triad • Prehospital treatment includes pericardiocentesis
Signs and Symptoms of Pericardial Tamponade • Hypotension • Pulsus paradoxus tachycardia • Beck’s triad (JVD, narrow pulse pressure, muffled heart tones)
Specific Thoracic Injuries • Cardiac injuries • Blunt cardiac injuries • Myocardial rupture • Myocardial infarction (traumatic) • Myocardial contusion • Myocardial concussion • Penetrating cardiac injuries
Specific Thoracic Injuries • Great vessel injuries • Blunt trauma to the great vessels • Penetrating trauma to the great vessels
