Plastic bronchitis caused by Haemophilus influenzae

Plastic bronchitis is characterized by sputum obstructing the bronchus and causing atelectasis. Bronchoscopic removal of the clogged bronchial cast is typically performed, but small-diameter bronchoscopes with narrow suction ports cannot achieve adequate suction. Suction using a bronchoscope as a guide sheath may be effective for treating plastic bronchitis in children.
