Anaesthesia · Airway management: needle cricothyroidotomy in children
Sample itemA 4-year-old with an impacted foreign body at the glottis cannot be intubated, and SpO2 is falling despite bag-mask ventilation. What is the preferred emergency front-of-neck access?
Original practice item, not a recalled exam question. Nothing here is recorded.
The answer and the reasoning
D. Needle cricothyroidotomy with a large cannula
In children, surgical cricothyroidotomy is avoided because the cricothyroid membrane is tiny and the cricoid is narrow and easily damaged. Needle cricothyroidotomy with a 14 to 16 gauge cannula, with oxygen insufflation, is used instead as a bridge. Tracheostomy takes too long in an emergency.
Option by option
A. Retrograde intubation
Retrograde intubation needs time and a patent glottis, which this child does not have.
B. Elective tracheostomy
Tracheostomy is too slow in an acute hypoxic emergency.
C. Surgical cricothyroidotomy with a 6 mm tube
A surgical technique with a larger tube risks damaging the small cricoid.
D. Needle cricothyroidotomy with a large cannula (correct)
Correct. A cannula through the membrane is the safe emergency route in a young child.
