Categories of Chest Injuries
• Closed injuries
– No break occurs in the skin over the
chest wall
– Usually the result of blunt trauma
• Open chest injuries
– Break in the skin over the chest wall
– Injuries result from penetrating trauma
35-5
Closed Chest Injuries
35-6
Rib Fractures
• Common injury due to
blunt chest trauma
– May be associated
underlying lung or
heart injury
• Seat belts occasionally
cause injury
35-7
Rib Fractures
• Ribs 1-3
– Protected by shoulder
girdle
– Fractures associated with
significant trauma
• Ribs 4-9
– Most commonly fractured
35-8
Rib Fractures
Signs and Symptoms
• Localized pain at the • Chest wall deformity
fracture site
• Crepitus
• Self-splinting of the
• Swelling and/or
injury
bruising at fracture
• Pain on inspiration
site
• Shallow breathing
• Tenderness on
palpation
• Possible
subcutaneous
emphysema
35-9
Rib Fractures
Emergency Care
• Spinal stabilization if spinal injury suspected
• Establish and maintain an open airway
• Give oxygen
• Encourage patient to breathe deeply
• Do not apply tape or straps to the ribs or
chest wall
• Allow patient to self-splint
• Perform ongoing assessments
35-10
Flail Chest
• Occurs when two or
more adjacent ribs are
fractured in two or more
places or when the
sternum is detached
• “Flail segment”
35-11
Flail Chest
• Paradoxical movement
35-12
Flail Chest
• Life-threatening injury
• Respiratory failure may occur due to:
– Bruising of underlying lung and
hemorrhage of the alveoli
– Chest wall instability and pain
– Interference with normal "bellows" action
of the chest
35-13
Flail Chest
Signs and Symptoms
•
•

•
•
•
•
•

and pulseless.
– Many patients are cyanotic.
– Seizures have been observed in some
individuals.
– Bruising of the chest wall present in about
one-third of patients.
• Survival is most dependent on early
resuscitation (within 1 to 3 minutes of the
event), including CPR and defibrillation.
