Changing indications and antenatal prognostic factors for ex‐utero intrapartum treatment procedures

Objective In cases of suspected neonatal airway obstruction, the ex‐utero intrapartum treatment (EXIT) procedure is used to secure the airway while a fetus remains on placental circulation. We report indications and outcomes from all EXIT procedures at a tertiary obstetric unit between 1997 and 2020. Method Retrospective cohort study with data collected from maternal and neonatal medical records. Results Indications for EXIT procedures were micrognathia (n = 7), lymphatic malformations (n = 5), cervical teratomas (n = 4), goiters (n = 2), and intra‐oral epulis (n = 1). Infants with a fetal teratoma were delivered earliest due to 75% presenting with preterm premature rupture of membranes or preterm labor. Low birth weight was found in 75% of these neonates; they did not survive 1 year. Intubation at EXIT occurred for 58% (n = 11) of babies, and six neonates required a tracheostomy. In four cases of fetal micrognathia, the inferior facial angle (IFA) was noted to be
