2. Statistics
Chest injuries are the second leading cause of
trauma deaths each year.
 Most thoracic injuries (90% of blunt trauma and
70% to 85% of penetrating trauma) can be
managed without surgery.


3. Main Causes of Chest Trauma

Blunt Trauma- Blunt force to chest.

Penetrating Trauma- Projectile that enters
chest causing small or large hole.

Compression Injury- Chest is caught
between two objects and chest is
compressed.

5. Rib Fractures

Incidence
– Infrequent until adult life
– Significant force required
– Most often elderly patients

7. Rib Fractures
Pathophysiology





Most often caused by blunt trauma
Ribs 3 to 8 are fractured most often (they are thin
and poorly protected)
Respiratory restriction as a result of pain and
splinting
Intercostal vessel injury
Associated complications
– First and second ribs are injured by severe
trauma
– Tracheobronchial tree injury
– Vascular injury

8. Rib Fractures

Assessment findings
– Localized pain
– Pain that worsens with movement, deep
breathing, coughing
– Point tenderness

Most patients can localize the fracture by pointing
to the area (confirmed by palpation).
– Crepitus or audible crunch

9. Rib Fractures
Management

Airway and ventilation
– High-concentration oxygen
– Positive-pressure ventilation
– Encourage coughing and deep breathing

Pharmacological
– Analgesics
– Intercostal block
– Epidural block

10. Rib Fractures
Complications
Splinting, which leads to atelectasis and
ventilation-perfusion mismatch
 Pneumonia can leads to empyema


11. Flail Chest
Pathophysiology

Two or more adjacent ribs fractured in two
or more places producing a free-floating
segment of chest wall
Flail chest usually results from direct impact.

13. Flail Chest

14. Flail Chest
Pathophysiology (2 of 2)

Respiratory failure due to:
– Underlying pulmonary contusion

The blunt force of the injury typically
produces an underlying pulmonary
contusion.
– Associated intrathoracic injury
– Inadequate bellows action of the chest

16. S/S of Flail Chest







Chest wall contusion
Respiratory distress
Paradoxical chest wall movement
Pleuritic chest pain
Crepitus

17. Flail Chest is a True Emergency

18. Flail Chest
Management

Airway and ventilation
– High-concentration oxygen.
– Positive-pressure ventilation may be needed.
» Reverses the mechanism of paradoxical
chest wall movement
» Restores the tidal volume
» Reduces the pain of chest wall movement
» Assess for the development of a
pneumothorax
– Evaluate the need for endotracheal intubation.
– Stabilize the flail segment (controversial).

19. Bulky Dressing for splint of Flail
Chest


and Triangular
Bandages to splint
ribs.

associated injuries


–
–
–
–
–
Advanced age
Seven or more rib fractures
Three or more associated injuries

21. Simple/Closed Pneumothorax



Opening in lung tissue
that leaks air into chest
cavity
Blunt trauma is main
cause
Usually self correcting

22. Closed (simple) pneumothorax
– Incidence
» 10% to 30% in blunt chest trauma
» Almost 100% with penetrating chest trauma

23. Closed (Simple) Pneumothorax
Pathophysiology

May occur in the absence of rib fractures from:
– A sudden increase in intrathoracic pressure
generated when the chest wall is compressed
against a closed glottis (the paper-bag effect)
» Results in an increase in airway pressure and
ruptured alveoli, which lead to a
pneumothorax

Small tears self-seal; larger ones may progress.

Ventilation/perfusion mismatch.

25. Closed Pneumothorax
Assessment Findings










Tachycardia
Respiratory distress
Absent or decreased breath sounds on the affected side

side

26. Closed Pneumothorax
Management

Airway and ventilation
– High-concentration oxygen.
– Positive-pressure ventilation if necessary.
– If respiration rate is <12 or >28 per minute,
ventilatory assistance with a
bag-valve mask may be indicated.

27. Open Pneumothorax

Incidence
– Usually the result of penetrating trauma
» Gunshot wounds
» Knife wounds
» Motor vehicle collisions
» Falls

28. Open Pneumothorax



Opening in chest cavity that allows air to enter
pleural cavity
Causes the lung to collapse due to increased
pressure in pleural cavity
Can be life threatening and can deteriorate
rapidly

30. Open Pneumothorax
Pathophysiology (1 of 2)

An open defect in the chest wall (>3 cm)
– If the chest wound opening is greater than twothirds the diameter of the trachea, air follows the
path of least resistance through the chest wall
with each inspiration.
– As the air accumulates in the pleural space, the
lung on the injured side collapses and begins to
shift toward the uninjured side.

 Decreased lung sounds on affected side
 Red Bubbles on Exhalation from wound
( Sucking chest wound)


39. Open Pneumothorax
Management (1 of 2)

Airway and ventilation:
– High-concentration oxygen.
– Positive-pressure ventilation if necessary.
– Assist ventilations with a bag-valve device and
intubation as necessary.
– Monitor for the development of a tension
pneumothorax.

Circulation—treat for shock with crystalloid
infusion.

40. Open Pneumothorax
Management (2 of 2)

Nonpharmacological
– Occlude the open
wound—apply an
occlusive petroleum
gauze dressing (covered
with sterile dressings)
and secure it with tape.

41. Occlusive Dressing

Asherman Chest Seal

42. Plus Care
Monitor Heart Rhythm
 Establish IV Access and Draw Blood
Samples
 Airway Control that may include Intubation
 Monitor for Tension Pneumothorax


43. Tension Pneumothorax
Air builds in pleural space with no where
for the air to escape
 Results in collapse of lung on affected side
that results in pressure on mediastium,the
other lung, and great vessels


44. Tension Pneumothorax
Pathophysiology



Occurs when air enters the pleural space from a
lung injury or through the chest wall without a
means of exit.
Results in death if it is not immediately recognized
and treated.
When air is allowed to leak into the pleural space
during inspiration and becomes trapped during
exhalation, an increase in the pleural pressure
results.

45. Tension Pneumothorax Pathophysiology
(2 of 2)
Increased pleural pressure produces
mediastinal shift.
 Mediastinal shift results in:

– Compression of the uninjured lung
– Kinking of the superior and inferior vena cava,
decreasing venous return to the heart, and
subsequently decreasing cardiac output

46. Tension Pneumothorax
Each time we inhale,
the lung collapses further. There
is no place for the air to
escape..

47. Tension Pneumothorax
Each time we inhale,
the lung collapses further. There
is no place for the air to
escape..

trauma
– May occur when an open pneumothorax has been
sealed with an occlusive dressing.

removing the dressing (air escapes with an audible
release of air).

56. Tension Pneumothorax Management (5 of 5)

Tension pneumothorax associated with closed
trauma
– If the patient demonstrates significant dyspnea and
distinct signs and symptoms of tension pneumothorax:
» Provide thoracic decompression with either a large-bore needle
or commercially available thoracic decompression kit.
» Insert a 2-inch 14- or 16-gauge hollow needle or catheter into
the affected pleural space.

Usually the second intercostal space in the midclavicular line
Insert the needle just above the third rib to avoid the nerve, artery, and
vein that lie just beneath each rib.
