A Few Remarks…

What you do matters!
• I went into EMS and Emergency Medicine
because I believe it matters.
– We routinely show up in the most terrifying
moments of other people’s lives
• To intervene when trauma or illness is threatening
health or sometimes, a very life
• To alleviate suffering
• To provide reassurance and a caring hand
– Society values this – you are one of the most
respected professions
![Page 21: To Needle or Not to Needle? Pneumothorax in the Field · To Needle or Not to Needle? Pneumothorax in the Field ... Case 1 •76 yo F with SOB ... –Spontaneous •Or secondary (lung](https://reader030.vdocuments.site/reader030/viewer/2022021711/5b385d6e7f8b9a4b0a8b9085/html5/thumbnails/21.jpg)
But it’s scary as _____!
• What we do matters – so it matters that we
do it right
• Sometimes, it’s literally “life or death”
• Do not have luxury of time to “look it up”
• Must know what to do, how to do it, and
exactly when to do it
• Must be facile with our skills
• This is why we are here today!
![Page 22: To Needle or Not to Needle? Pneumothorax in the Field · To Needle or Not to Needle? Pneumothorax in the Field ... Case 1 •76 yo F with SOB ... –Spontaneous •Or secondary (lung](https://reader030.vdocuments.site/reader030/viewer/2022021711/5b385d6e7f8b9a4b0a8b9085/html5/thumbnails/22.jpg)
Anecdotes vs. Evidence
• Anecdotes
– Stories we tell each other
– Single patients we saw
• Can be good or bad
– Not evidence-based
– Should not shape your practice
– Don’t let anecdotes be how you refine your
craft!
![Page 23: To Needle or Not to Needle? Pneumothorax in the Field · To Needle or Not to Needle? Pneumothorax in the Field ... Case 1 •76 yo F with SOB ... –Spontaneous •Or secondary (lung](https://reader030.vdocuments.site/reader030/viewer/2022021711/5b385d6e7f8b9a4b0a8b9085/html5/thumbnails/23.jpg)
Anecdotes vs. Evidence
• Evidence (aka “the literature”)
– Be familiar with the literature
– Know how to find it
– Read with a degree of skeptism
• What biases & motives do the authors have?
• What are the flaws in the methodology?
• Do the results apply to your patient population?
![Page 24: To Needle or Not to Needle? Pneumothorax in the Field · To Needle or Not to Needle? Pneumothorax in the Field ... Case 1 •76 yo F with SOB ... –Spontaneous •Or secondary (lung](https://reader030.vdocuments.site/reader030/viewer/2022021711/5b385d6e7f8b9a4b0a8b9085/html5/thumbnails/24.jpg)
Evidence-informed Medicine
• No study is perfect
• Few are so good that they alone warrant a
change in practice
• Each study must be interpreted in the context of
the existing literature on the subject
• Practice evidence-informed medicine
– Assimilation of the body of existing literature
with expert analysis

Anatomy Review
• Chest wall
– The soft tissues and bones that enclose the upper
torso and its contents
• Lungs
– The organs, located inside the chest, which are
responsible for gas exchange between the
environment and our body
• Mediastinum
– The central part of the chest containing the heart and
great blood vessels

Terminology Review
• Pleura:
– The outer lining of the lungs
– Consists of two layers:
• Parietal pleura
– The layer lining the chest wall
• Visceral pleura
– The layer lining the lungs
• Normally, they are stuck together as one….

Terminology Review
• Pleural space
– The area between the parietal & visceral pleura
– Adheres the lungs to the chest wall
– Pressure is -5 mm Hg to keep layers together
– Is a POTENTIAL space
• Normally, it doesn’t exist
• However, in injury or illness, it can become a REAL space
(always abnormal) and fills with something…
• If connected to lung/airways or environment, pressure
gradient favors filling of pleural space

Focus on Pneumothorax
• 10-20 cases/100,000 people
• Affects men > women
• Can be primary (no underlying lung disease)
– Trauma
– Spontaneous
• Or secondary (lung disease)
![Page 42: To Needle or Not to Needle? Pneumothorax in the Field · To Needle or Not to Needle? Pneumothorax in the Field ... Case 1 •76 yo F with SOB ... –Spontaneous •Or secondary (lung](https://reader030.vdocuments.site/reader030/viewer/2022021711/5b385d6e7f8b9a4b0a8b9085/html5/thumbnails/42.jpg)
Causes of Pneumothorax
• Trauma
– Blunt chest trauma
• Broken ribs poking holes in pleura & lungs
– Penetrating chest trauma
• Stab/GSW puncture through pleura & lung
– Iatrogenic
• (oops!)
• Secondary causes (underlying lung disease)
– COPD (most common) or asthma
– Cystic fibrosis, interstitial lung disease
– Lung infection, AIDS
– Cancer

TENSION pneumothorax
• Definition?
“when there is significant ongoing air
accumulation in the pleural space,
increasing pressure, first causing the complete
collapse of the affected lung, and then pushing
the mediastinum into the opposite pleural
cavity…preventing blood from returning to
the heart…(then) shock…. (then) cardiac
arrest.”
Pollak, AN. “Emergency Care & Transportation of the Sick and Injured.” Chapter 27 Chest Injuries.
2005.

TENSION pneumothorax
What are some signs of tension PTX?
– Distended neck veins (JVD)
• May not be present if lots of blood loss
– Tracheal deviation?
• Maybe, but rare.
– Probably hypoxic & tachycardic, narrowed pulse pressure
– Absent breath sounds
– Hypotension (ALWAYS)
– Hemodynamic shock & collapse
– Eventually….cardiac arrest

Who to Needle?
• Tension pneumothorax!
– Is an immediate life threat
– Is a TRUE emergency
– Requires EMERGENT intervention to save
the patient’s life
– Is an indication for prehospital needle
decompression of the chest
![Page 56: To Needle or Not to Needle? Pneumothorax in the Field · To Needle or Not to Needle? Pneumothorax in the Field ... Case 1 •76 yo F with SOB ... –Spontaneous •Or secondary (lung](https://reader030.vdocuments.site/reader030/viewer/2022021711/5b385d6e7f8b9a4b0a8b9085/html5/thumbnails/56.jpg)
Who NOT to Needle?
• Uncomplicated pneumothorax:
– Is an URGENT condition
– Is not an immediate life threat
– Does NOT require needle decompression in
the field (or in the ED)
– May or may not require a chest tube in the ED
(depends on size, etc.)

Complications
• Performed when NOT indicated
– May commit patient to unnecessary chest tube who
otherwise would not get one
• Improper placement
– Not in pleural cavity (i.e. chest wall, blood vessel)
• Failure to decompress tension cardiac arrest
![Page 69: To Needle or Not to Needle? Pneumothorax in the Field · To Needle or Not to Needle? Pneumothorax in the Field ... Case 1 •76 yo F with SOB ... –Spontaneous •Or secondary (lung](https://reader030.vdocuments.site/reader030/viewer/2022021711/5b385d6e7f8b9a4b0a8b9085/html5/thumbnails/69.jpg)
Post-decompression
• Continue routine BLS/ALS
• High flow O2 via NRB
• Initiate transport without delay
• Be ready for potential recurrence!
– Repeat needle decompression if tension PTX
recurs

In Summary…
• Tension PTX is a life-threatening
complication of pneumothorax, resulting in
hemodynamic and respiratory collapse
• Tension pneumothorax is an indication
for emergent needle decompression.
• Pneumothorax withOUT tension is NOT an
indication for needle decompression
![Page 81: To Needle or Not to Needle? Pneumothorax in the Field · To Needle or Not to Needle? Pneumothorax in the Field ... Case 1 •76 yo F with SOB ... –Spontaneous •Or secondary (lung](https://reader030.vdocuments.site/reader030/viewer/2022021711/5b385d6e7f8b9a4b0a8b9085/html5/thumbnails/81.jpg)
In Summary…
• Needle decompression is performed with a 14
gauge, 3.25” angiocatheter (or larger) in one of
two locations:
– 2nd intercostal space, mid-clavicular line
– 4th-5th intercostal space, mid-axillary line
• Common pitfalls include inadequate depth and
improper site selection

Parting words….
Keep reading, keep learning.
What you do is just too darn
important not to.
