A new protocol for the perinatal management of patients with congenital diaphragmatic hernia with severe hypoplastic lungs and its clinical application.
It is prerequisite for the pre-operative management of patients with congenital diaphragmatic hernia (CDH) to avoid the factors that increase pulmonary vascular resistance, because such patients easily fall into the state of persistent fetal circulation (PFC). In this paper, a new protocol is proposed for the perinatal management of CDH patients to prevent the PFC which is facilitated by the enlargement of hernia and the deviation of mediastinum caused by spontaneous breathing just after birth. We also describe the usefulness of this protocol based on our experience in which we successfully treated a patient with CDH with severe hypoplastic lungs that were diagnosed antenatally by ultrasonographic examination. In treating the CDH patient with severe hypoplastic lungs, it is effective for the respiratory control and the prevention of PFC to administer morphine and pancuronium to the neonate through the umbilical vein before the resection of the umbilical cord. In the case of Cesarean section, in addition to the direct administration of morphine to the patient, administration of morphine to the patient's mother just before the delivery is more effective to prevent PFC, which can be easily induced by the initial resuscitation at birth.
