Ex-utero intrapartum therapy.

摘要: The ex-utero intrapartum therapy (EXIT) procedure was designed to secure the airway at delivery in fetuses who had undergone tracheal occlusion for severe congenital diaphragmatic hernia. EXIT then adapted deliveries where may be difficult secure, such as large neck masses or high obstruction. Subsequently, use of has been extended fetal anomalies resuscitation compromised, including thoracic masses, hernia, pulmonary agenesis. key is preservation uteroplacental blood flow and gas exchange, using inhalational agents provide uterine relaxation, maintenance volume by amnioinfusion only partial exposure fetus. This provides time procedures laryngoscopy, bronchoscopy, vascular access, resection lung cannulation extracorporeal membrane circulation, order convert an emergent crisis a controlled situation.
