Chest trauma can represent a major burden and lead to significant morbidity and mortality. Chest injuries require prompt evaluation and management to address life-threatening injuries like tension pneumothorax, hemothorax, and cardiac injuries. The chest is divided into the thoracic cavity containing the lungs, heart, and great vessels which are vulnerable to injury from blunt or penetrating trauma. Common injuries include rib fractures, flail chest, pulmonary contusions, and pneumothorax. Immediate airway control and treatment of life-threatening injuries is essential, followed by management of potential injuries and complications to optimize outcomes.
2. INTRODUCTION
⢠Trauma represents a major burden in surgery
emergency and is a leading cause of morbidity and
mortality worldwide.
⢠Chest trauma is seen in about 50% of trauma victims
⢠Mortality : 25%
⢠Approximately 16,000 deaths per year in India are as
a result of chest trauma.
4. ⢠Thoracic cavity contains three major anatomical systems:
Airway
Lungs
Cardiovascular system.
⢠Accounts for app. 25% of mortality in trauma patients
6. Boundaries Of Thoracic Wall
Anterior :
⢠Sternum
⢠Costal Cartilages
Superior
⢠Supra Pleural Membrane
Inferior
⢠Respiratory Diaphragm
7. Boundaries Of Thoracic WallâŚ

LEFT PLEURA
Sternoclavicular joint to 4th costal cartilage
Deviates 1 inch left at 6th costal cartilage to
form cardiac notch
RIGHT PLEURA
Sternoclavicular joint to 6th costal cartilage
INFERIOR MARGIN : Bilateral extending from 8th rib in Anterior
axillary line to 10th rib in mid axillary line to last thoracic spine
POSTERIOR MARGIN : Along vertebral column
9. MUSCLES OF THORACIC WALL
⢠Thoracic wall:
⢠External intercostal muscles,
⢠Internal intercostal muscles,
⢠Innermost intercostal muscles,
⢠Subcostalis, and
⢠Transversus thoracis
⢠Posterior Thorax:
⢠Levatores costarum
⢠Serratus posterior superior and inferior muscles
10. MUSCLES OF THORACIC WALLâŚ
⢠Anterior/Superficial Thorax:
⢠Pectoralis major and minor muscles
⢠Subclavius
⢠Serratus anterior
⢠Floor:
⢠Diaphragm
⢠These muscles act to change the volume of the thoracic cavity during respiration.
13. PHYSIOLOGY OF CHEST WALL
⢠Skin and soft tissue overlie the musculature of the bone: creating
the barrel-like structure of the chest wall.
⢠The thorax moves with chest wall to alter the intrathoracic
pressures with inspiration and expiration.
⢠"Bucket handle" movement: elevation of the ribs (mainly by the
external intercostals)
⢠"Pump handle" movement: elevation of the sternum (by the
sternomastoid muscle)
15. PATHOPHYSIOLOGY IN CHEST TRAUMAâŚ
ď§ Deformity of the chest wall may alter respiratory
mechanics leading to :
⢠Hypercarbia
⢠Respiratory Acidosis
⢠Respiratory Failure
⢠Increased shunt fraction via pulmonary contusion,
hemorrhage or edema causes hypoxemia.
16. SEQUENCE OF EVENTS IN CHEST
TRAUMA
Trauma to chest (injury to lung parenchyma, rib cage and musculature)
Extravasation of serum protein and plasma
Accumulation of fluid in interstitial space and intra alveolar spaces
Cellular response to injury causes fluid loss from capillaries

2. Ecchymosis
3. Muscle spasm
4. Localised pain, tenderness at fracture site
DIAGNOSIS: CXR
31. RIB FRACTURES
Pain prevents the injured area from moving which
consequently leads to hypoventilation.
⢠Decreased chest-wall movement can cause
atelectasis
32. Management Of Rib Fractures
⢠PAIN CONTROL
Analgesia ( 1-2 weeks).
Narcotics
Regional analgesia should be considered.
Thoracic epidurals are the gold standard.
⢠CHEST PHYSIOTHERAPY

44. OPEN PNEUMOTHORAX
⢠Sucking chest wall wound from penetrating injury.
⢠Caused by a defect in the chest wall greater than 2/3
diameter of the trachea.
⢠Air moves preferentially through chest-wall defect
resulting in ineffective ventilation & hypoxia.

⢠Chest pain.
ď§ Physical exam :
⢠Sucking air from the wound
⢠Shallow respirations
⢠Decreased lung sounds on affected side along
with subcutaneous emphysema
⢠Red bubbles exhalation seen from open chest
wound
46. TREATMENT
⢠Tube thoracostomy placed on same side of the wound but
at a different location.
⢠Three-sided occlusive dressing:
⢠The sterile occlusive dressing should be large enough
to overlap the wounds edges and then taped securely
on 3 sides to provide a flutter type valve effect.
⢠As the patient breathes in the dressing prevents air
from entering but in expiration allows air to escape
52. TENSION PNEUMOTHORAX
⢠Air keeps on entering
the pleural cavity
without an escape.
⢠It leads to lung collapse,
and contralateral
compression of lung and
cardiovascular system.
53. The trachea is
pushed to
contralateral
side.
Compression
of great
vessels and
vena caval
structures
TENSION PNEUMOTHORX

allow time for formal decompression.
⢠Followed by tube thoracostomy
57. ⢠Indication for Surgery:
⢠If lung remains unexpanded or there is a persistent
air leak 72 hours
Thoracoscopy or thoracotomy is considered
⢠An initial parenteral dose of first generation
cephalosporin is recommended.
59. HEMOTHORAX
⢠Accumulation of blood in the pleural space prevents
adequate ventilation and compresses the lung.
⢠caused by penetrating trauma>blunt trauma
⢠Bleeding can be due to injury from the lungs or vessels
{lung parenchyma>vessels}
