High-flow nasal cannula for the treatment of life-threatening plastic bronchitis.

Plastic bronchitis (PB) is characterized by the formation of bronchial casts. It most frequently occurs in children with congenital heart disease, particularly post-Fontan procedure. Several medical and surgical therapies have been described in the literature with variable success. To our knowledge, this is the first time that overnight use of home high-flow nasal cannula is reported as a therapy to prevent recurrence of bronchial cast production in a child with PB post-Fontan.
