Q

If airway can’t be secured what should you do?

A

Cricothyroidotomy

Q

What is Beck’s triad of cardiac tamponade?

A
  • Raised JVP
  • Hypotension
  • Muffled heart sounds
  • (also pulsus paradoxus)
21
Q

What is the investigation for cardiac tamponade?

A
  • FAST scan usually
  • Echo is gold standard
22
Q

What are some signs of cardiac tamponade?

A
  • Electrical alternans on ECG
  • Absent Y descent in JVP
23
Q

Management of tamponade in peri-arrests?

A

Thoracotomy or pericardiocentesis

24
Q

Management of tension pneumothorax?

A

1) 2 wide bore cannulae in 2nd IC space mid-clavicular line
2) Insert chest drain in triangle of safety (4-6 IC space, lateral edge of lat dorsi and pec major)

25
Management of open pneumothorax?
1) High flow oxygen and dressing with one side open 2) Chest drain
26
How does massive haemothorax present compared to tension pneumothorax?
Presents the same except: - Hypovolaemic - Collapsed neck veins (distended in tension) - Dull percussion (hyperreasonant in tension) - White on CXR (black in tension)
27
When does a haemothorax become massive?
When a third of blood volume is lost (approx 1500ml)
28
Management of massive haemothorax?
- Restore circulating volume before inserting drain (will cause CV collapse) - Insert chest drain (can dislodge a clot) - Thoracotomy if V large (>1500ml comes from chest drain) or a clot
29
What are the complications of flail chest?
- Pulmonary contusion (mainly) - Can cause pneumo- or haemothorax
30
Management of flail chest?
- Good pain management - Pain worsens respirations which worsens the problem
31
How does aortic injury occur?
Shearing forces from blunt deceleration (e.g. RTA/fall)
32
How does aortic injury present?
Similar to dissection
33
What are the 2 main imaging modalities for aortic injury?
- Contrast enhanced CT is best - X-ray
34
What will an X-ray show in aortic injury?
- Widened mediastinum - Loss of aortic knuckle - Filling of AP window - Elevated right main bronchus and depressed left one - Tracheal deviation
35
What is the management of aortic injury?
- Surgical graft repair - Permissive hypotension
36
What are the signs of a tracheobronchial injury?
- Hoarse voice - Haemoptysis - Surgical emphysema in neck, chest wall and mediastinum
37
How is tracheobronchial injury diagnosed?
Bronchoscopy
38
Management of tracheobronchial injury?
- Airway protection - Surgical repair
39
When should you consider cardiac contusion?
In sternal fracture (heart compression)
40
What are the signs of cardiac contusion?
Tissue behaves like infarcted tissue: - ST elevation - Raised troponin - Same complications ass MI
41
What will a chest X-ray show in pulmonary contusion?
Serial CXR shows increased patchy consolidation
42
Management of pulmonary contusion?
Supportive
43
What does chest X-ray show in diaphragmatic tear?
Loops of bowel in chest or gastric bubble in thorax
44
Management of diaphragmatic tear?
Surgical repair and gastric tube
45
Signs of ARDS?
- Rapid onset severe hypoxia - Think with unexplained tachycardia and hypoxemia post trauma
46
Causes of ARDS?
- 48 hours post trauma especially chest (pulm contusion 50% get this) - Sepsis (main cause) - Other - pneumonia, aspiration, pancreatitis, fat embolism, inhalation, transfusion and covid
47
Management of ARDS?
- ICU -> ventilation -> PEEP - Proning - Negative fluid balance - diuretics and fluid restriction - Reduce pulm pressure -> Nitrous oxide and prostacyclins
