Anaesthesia · Paediatric anaesthesia: foreign body in bronchus

Sample item

During rigid bronchoscopy for an inhaled foreign body in a child, which ventilation strategy is preferred during induction?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

A. Maintain spontaneous ventilation

Positive pressure may push a foreign body distally or convert a partial obstruction to a ball-valve one. Spontaneous ventilation with a volatile agent and topical lignocaine is therefore preferred.

Option by option

  • A. Maintain spontaneous ventilation (correct)

    Correct. Spontaneous ventilation avoids air trapping and displacement.

  • B. Positive pressure ventilation with full paralysis

    Positive pressure can dislodge or lodge the foreign body.

  • C. Mask ventilation at high pressure

    High-pressure ventilation risks barotrauma.

  • D. Apnoeic oxygenation without monitoring

    Unmonitored apnoea is unsafe.
