3. Epidemiology
๏ถ 10-20% of polytrauma
๏ถ 2nd most common cause
of death after head
trauma
๏ถ 25% of death in
polytrauma
4. India
๏ถMost common cause is
Motor vehicle injury
๏ถ 6% of global vehicular
accidents
๏ถ Male , mean age 21-40
years
๏ถ Violence ,industrial
accidents, falls, assaults,
gunshot
10. Blunt Thoracic Trauma
๏ถ Globally = Road traffic accident represent the
most common cause
๏ถ Eastern mediterranean countries = Assault
๏ถ Other causes
- Assault
- Fall
- Industrial
- Sports
- Animal attacks
11. Blunt trauma contdโฆโฆ
๏ถ Results from kinetic energy forces
- Blast
- Crush
- Decelaration
๏ถ Blast
- Pressure wave
- Tear blood vessels & disrupt alveolar tissue
- Disruption of tracheobronchial tree
- Traumatic diaphragm rupture
12. ๏ถ Crush (Compression)
โ Body compressed between an object and
a hard surface
โ Direct injury of chest wall and internal
structures
๏ถ Deceleration
โ Body in motion strikes a fixed object
โ Internal structures continue in motion
โ Force exceeds tissue tensile strength
โ Ligamentum Arteriosum shears aorta
13. Penetrating Trauma
๏ถPenetrating Trauma
โ Low Energy
๏ถ Arrows, knives
โ High Energy
๏ถ Military, hunting rifles &
high powered hand guns
๏ถ Extensive injury due to
high pressure cavitation
23. Diaphragmatic Rupture
๏ถ More common on left side
๏ถ Commonly diagnosed during
laparatomy
๏ถ Chest X-ray with gastric
tube, contrast study
๏ถ Treatmant is direct repair
25. Esophageal Injury
๏ถAssessment Findings
- Pain/shock out of proportion to the apparent injury
- Dysphagia, Respiratory distress
- Particulate matter in the chest tube
- Mediastinitis, pneumomediastinum, emphysema
- Contrast study
- Direct repair
26. Traumatic Aortic Rupture
๏ถ Common cause of sudden
death
๏ถ Slim chances of survival
๏ถ Ligamentum arteriosum
๏ถImmediate survivors, early
diagnosis and treatment
27. Signs and symptoms
๏ถ Non specific : High index of suspicion
๏ถ Burning or Tearing Sensation in chest or shoulder
๏ถ Rapidly dropping Blood Pressure and increasing pulse
๏ถ Decreased or loss of pulse or BP on left side compared to
right side
๏ถ Rapid Loss of Consciousness
28. Management
๏ถ ABCโs and RAPID TRANSPORT to higher center
๏ถ Angiography is gold standard
๏ถ Other investigation non specific
๏ถ Primary repair or resection and grafting
29. Flail chest
๏ถ Flail chest has mortality of 10 โ 20 % and typically
associated with pulmonary contusion
๏ถTraditional = Paradoxical movement and
โPendelluftโ
โ Pulmonary contusion causes major respiratory
compromise and flail chest secondary problem of
pain and splinting โ
36. Management
๏ถ Principles of fluid management ?
๏ถ Invasive or non- invasive ventilation ?
๏ถ Optimal mode of ventilation ?
๏ถ Role of surgical fixation ?
๏ถ Role of steroids ?
Rule of thumb = Adequate analgesia and chest
physiotherapy
37. Management contdโฆ
๏ถ Humidified oxygen
๏ถ Analgesia
๏ถ Ventilation and re-expansion of lung
๏ถ Sandbag and extensive strapping
contraindicated
๏ถ No role of steroids
38. Fluid management
๏ถโCongestive atelectasisโ - Aggressive fluid
resuscitation increase the size of lesion
Trinkle et al 1973
๏ถ Colloids better than crystalloids
๏ถ Pulmonary dysfunction unrelated to hemodilution
๏ถ Mortality related to pulmonary function on
admission
โ Fluid resuscitation should not be restricted to
maintain adequate tissue perfussionโ
39. Ventilatory support
๏ถ Initially = โ obligatory mechanical ventilation โ
๏ถ Longer hospital stay, increase mortality and
morbidity
โ Correct abnormalities of gas exchange rather to
overcome instability of chest wall โ
40. Indication for intubation
๏ถ Severe head injury
๏ถ Several associated injury
๏ถ Shock
๏ถ Fracture of eight or more
ribs
๏ถ Age > 65 years
๏ถ Previous pulmonary
disease
๏ถ RR > 35/mt
๏ถ Pao2 < 60mmHg
๏ถ PaCO2 > 55mmhg
๏ถ SPo2 < 90%
41. Which mode ?
๏ถ No difference between CMV and IMV
๏ถ CPAP or PEEP of 10-15 cm H2O
๏ถ Alveolar recruitment and increase FRC
๏ถ Independent lung ventilation in severe unilateral
chest trauma
๏ถ HFOV : Failure of conventional methods
42. Indication of surgical repair
๏ถ Thoracotomy
๏ถ FC with respiratory insufficiency without
pulmonary contusion
๏ถ Severe flail chest requiring prolonged ventilatory
support
๏ถ Progressive dislocation of ribs
43. Summary
โ Flail chest component causes short term respiratory
dysfunction, Pulmonary contusion responsible for
long term dyspnoea, low FRC , PaO2 โ
โ Adequate analgesia and chest physiotherapy is
mainstay of treatment โ
53. Epidural contdโฆ.
๏ถ Equally effective pain scores but superior PFT
Cicala et al 1990
๏ถ Combination therapy
๏ถ Lower pain scores
๏ถ IV narcotic sparing Logas et al 1997
๏ถ Lower doses of both
๏ถ Boluses has higher rate of complication
kurek et al 1997
57. Intercostal nerve block
Advantages Disadvantages
๏ถ Increase PEFR ,lung
volumes
๏ถ Less hypotension
๏ถ Bladder function
preserved
๏ถ Palpation of fractured
ribs
๏ถ LA Toxicity
๏ถ Difficult for upper ribs
๏ถ Multiple infections
๏ถ Pneumothorax
58. Intrapleural anesthesia
Advantages Disadvantages
๏ถ Unilateral block
๏ถ Similar to intercostal
๏ถ LA lost via chest tube
๏ถ Gravity dependent
๏ถ Pneumothorax
๏ถ Impair diffusion of LA
๏ถ Diaphragmatic function
59. Newer modalities
๏ถ 5 % lignocaine patch ( LIDODERM )
๏ถ No opiod sparing versus placebo group
Ingalls et al 2010
60. Summary
๏ถEpidural analgesia: Optimal modality of pain
control and preferred technique after severe
blunt thoracic trauma
๏ถ Safe with negligible complications
๏ถ PVB when ED is contraindicated
๏ถ Combination of narcotic and LA superior
