HEFT EMcast has produced an excellent podcast summary of the literature demonstrating that needle decompression at the 2nd intercostal space at the midclavicular line (2ICS MCL) is likely to fail. They review a systematic review and meta-analysis by Laan et al in 2015 that suggests the fifth intercostal space at the anterior axillary line (5ICS AAL) is less likely to fail .
Problems with the 2ICS MCL (For more detail on this, see this post)
- Chest Wall Thickness – to achieve a success rate >90% of the time with needle decompression at the 2ICS MCL, a [1,2]
- The 2ICS MCL is Difficult to Find– one study of emergency physicians found that providers could find the 2ICS MCL 60% of the time. Similarly, a blinded cadaveric study in which naval corpsmen who had just had a refresher course in needle decompress were asked to needle decompress cadavers at the 2ICS MCL and 5ICS AAL. They found 80% correct placement in the 5ICS AAL group compared with a mere 30% in the 2ICS MCL group [3,4].
- Important vascular structures nearby – the heart and great arteries lie nearby the 2ICS MCL and given the frequent misplacement of these catheters, these structures may be injured. Of note, placement aiming for the 5ICS AAL, if too inferiorly placed, could result in liver or splenic injury.
We delve into core content on pneumothorax and empyema using Rosen’s Medicine (8e), Chapters 77 and Tintinalli’s Emergency Medicine: A Comprehensive Study Guide (8e) Chapters 68
Smaller bore percutaneous tubes (seldinger technique) are becoming increasingly common, even in traumatic pneumothorax. These tubes have the advantage of smaller size, less pain, and reduced infection. However, they may be more prone to kinking and may be less desireable for some fluid collections [6-19]. See this post for more on percutaneous tubes.
Open pneumothorax (“sucking chest wound”): communication between the surrounding environment and the pleural space, often due to penetrating trauma but may occur in its absence.
- Treatment: 3 sided dressing (occlusive dressing could create tension) followed by chest tube (not inserted into wound).
Infection between the visceral pleura which covers the lung and the parietal pleura which covers the thoracic wall.
- Parapneumonic effusions (i.e. effusions that came as a result of an underlying pneumonia)- most common causes of pneumonia (s. pneumo or s. aureus. or H flu if not vaccinated)
- Trauma (iatrogenic or otherwise, i.e. retained hemothorax): gram negative bacilli.
- Pleuritic chest pain
- Decreased breath sounds.
- Exudative (early) – drainage, antibiotics
- Fibropurluent (middle) – fibrinolytics +/- video assisted thorascopic surgery (VATS)
- Organizational (late) – VATS and/or surgery
Generously Donated Rosh Review Questions
Question 1. A 22-year-old woman with a history of asthma presents with chest pain. Over the last several days, the patient has been coughing due to an asthma exacerbation. Today she developed sharp chest pain in the middle of her chest. A chest X-ray is shown below.[polldaddy poll=9349650] Answer
Question 2. You are caring for an intubated patient diagnosed with sepsis that is awaiting a bed in the intensive care unit. The patient has peripheral intravenous access, however you decide to place a right-sided subclavian central venous catheter in order to measure central venous pressure, assess volume status and determine if vasopressors are indicated. Shortly after successful line placement, the patient becomes hypotensive and develops high peak airway pressures. [polldaddy poll=9349659] Answer
