Question

A patient presented with RTA (Road Traffic Accident) leading to breathlessness and decreased air entry into the right lung and the patient is hypotensive. What is the next step?

• A. Needle inserted at 2nd ICS in MCL
• B. Needle inserted at 5th ICS in mid axillary
• C. Fluid resuscitation using wide bore cannula
• D. Wide bore needle decompression

Hint:

Breathlessness with absent breath sounds and hypotension after trauma points to tension pneumothorax requiring emergency needle decompression.

Answer 1

The Correct Option is B

Step 1: Identify the diagnosis. Post-RTA, the patient has breathlessness, decreased air entry on the right side, and hypotension. This clinical triad -- absent breath sounds on one side + tracheal deviation + hypotension -- strongly suggests tension pneumothorax.

Step 2: Understand immediate management. Tension pneumothorax requires emergency needle decompression. Fluid resuscitation alone will not treat the underlying obstructive cause of hypotension.

Step 3: Identify the correct insertion site. Traditionally, needle decompression was performed at the 2nd intercostal space (ICS) in the mid-clavicular line (MCL). However, updated ATLS guidelines now recommend the 4th or 5th ICS in the mid-axillary line (MAL) as the preferred site in adults, because chest wall thickness at the mid-clavicular 2nd ICS may prevent needle reach in obese patients, whereas the axillary site has reliably thinner chest wall.

Conclusion: Needle decompression at the 5th ICS in the mid-axillary line is the correct current answer for tension pneumothorax in adults.
