Perinatal management of the anticipated difficult airway.

The ex-utero intrapartum treatment (EXIT) procedure was originally developed to reverse tracheal occlusion in fetuses with severe congenital diaphragmatic hernia that underwent fetal tracheal occlusion. The EXIT procedure has since been applied to a wide range of indications, but the primary indication remains securing a patent airway and providing respiratory support in fetuses with anticipated difficult airways. The authors review perinatal management of the anticipated difficult airway and their single-institution's experience with the EXIT procedure.
