YOU JUST NEVER KNOW WHEN TRAUMA WILL OCCUR!

INTRODUCTION• Each year there are nearly 150,000
accidental deaths in the United States
• 25% of these deaths are a direct result of thoracic trauma
• An additional 25% of traumatic deaths have chest injury as a contributing factor

REASON
As a Ranger First Responder, you must be able to identify and treat penetrating trauma to the chest!

Major Anatomy and Physiology of the Chest

OVERVIEW
• Causes of Thoracic Trauma
• Types, Signs and Symptoms, and Management of Thoracic Trauma
![Page 8: Thoracic trauma by dr.saleh bakar](https://reader036.vdocuments.net/reader036/viewer/2022062514/558b0e4ad8b42af03c8b4649/html5/thumbnails/8.jpg)
CAUSES OF THORACIC TRAUMA:
• Falls3 times the height of the patient
• Blast Injuriesoverpressure, plasma forced into alveoli
• Blunt Trauma • PENETRATING TRAUMA
![Page 9: Thoracic trauma by dr.saleh bakar](https://reader036.vdocuments.net/reader036/viewer/2022062514/558b0e4ad8b42af03c8b4649/html5/thumbnails/9.jpg)

OPEN PNEUMOTHORAX• Develops when penetration injury to the chest
allows the pleural space to be exposed to atmospheric pressure - “Sucking Chest Wound”
• Q- WHAT MAY CAUSE A SCW?
• Examples Include: GSW, Stab Wounds, Impaled Objects, Etc...
![Page 11: Thoracic trauma by dr.saleh bakar](https://reader036.vdocuments.net/reader036/viewer/2022062514/558b0e4ad8b42af03c8b4649/html5/thumbnails/11.jpg)
LARGE VS SMALL
• Severity is directly proportional to the size of the wound
• Atmospheric pressure forces air through the wound upon inspiration
![Page 12: Thoracic trauma by dr.saleh bakar](https://reader036.vdocuments.net/reader036/viewer/2022062514/558b0e4ad8b42af03c8b4649/html5/thumbnails/12.jpg)
S/S: OPEN PNEUMOTHORAX
• Shortness of Breath (SOB)
• Pain
• Sucking or gurgling sound as air moves in and out of the pleural space through the wound
![Page 13: Thoracic trauma by dr.saleh bakar](https://reader036.vdocuments.net/reader036/viewer/2022062514/558b0e4ad8b42af03c8b4649/html5/thumbnails/13.jpg)
MANAGEMENT OF SCW
• Apply an Asherman Chest Seal Occlusive dressing with a release valve
• Observe for development of a
Tension Pneumothorax

TENSION PNEUMOTHORAX
• Air within thoracic cavity that cannot exit the pleural space
• Fatal if not immediately identified, treated, and reassessed for effective management
![Page 17: Thoracic trauma by dr.saleh bakar](https://reader036.vdocuments.net/reader036/viewer/2022062514/558b0e4ad8b42af03c8b4649/html5/thumbnails/17.jpg)
Tension Pneumothorax Following Stab Wound

EARLY S/S OF TENSION PNEUMOTHORAX
• ANXIETY!
• Increased respiratory distress
• Unilateral chest movement
• Unilateral decreased or absent breath sounds
![Page 19: Thoracic trauma by dr.saleh bakar](https://reader036.vdocuments.net/reader036/viewer/2022062514/558b0e4ad8b42af03c8b4649/html5/thumbnails/19.jpg)
LATE S/S OF TENSION PNEUMOTHORAX
• Jugular Venous Distension (JVD)
• Tracheal Deviation
• Narrowing pulse pressure
• Signs of decompensating shock
![Page 20: Thoracic trauma by dr.saleh bakar](https://reader036.vdocuments.net/reader036/viewer/2022062514/558b0e4ad8b42af03c8b4649/html5/thumbnails/20.jpg)
JVD & TRACHEAL SHIFT
Decreased input and output from the heart with compression of the great vessels
![Page 21: Thoracic trauma by dr.saleh bakar](https://reader036.vdocuments.net/reader036/viewer/2022062514/558b0e4ad8b42af03c8b4649/html5/thumbnails/21.jpg)
JVD & TRACHEAL SHIFT
Increased pressure moves mediastinum and compresses the lung on the uninjured side
![Page 22: Thoracic trauma by dr.saleh bakar](https://reader036.vdocuments.net/reader036/viewer/2022062514/558b0e4ad8b42af03c8b4649/html5/thumbnails/22.jpg)
MANAGEMENT OF TENSION PNEUMOTHORAX
• Asherman Chest Seal
• Needle Decompression
• High flow oxygen (If available)
• Bag Valve Mask / Intubation
• Chest Tube (BN CCP/CASEVAC)

NEEDLE THORACENTESIS• Locate 2nd or 3rd Intercostal Space at the Midclavicular Line
• Insert a 14g needle/catheter over the top of the rib (“VAN”) into the pleural space
• Listen for air escape (WHOOSH!)
• Leave the catheter in place
• Reassess
