In this protocol, the investigators propose initiation of resuscitation during the period of delayed cord clamping in infants with congenital diaphragmatic hernia. This is a feasibility study that will assess tolerance of the participants (pregnant mother and their high-risk infants) to this method of resuscitation as well as the optimal setup and approach to resuscitation. Tolerance to this approach would provide these infants the benefits of delayed cord clamping while allowing for simultaneous resuscitation. The first aim of this study is to assess maternal and fetal tolerance to the procedure and determine the optimal approach to resuscitation. In addition to this the investigators will assess if initiation of resuscitation during the period of delayed cord clamping can stabilize gas exchange and prevent the hypercarbia and acidosis that ensues after birth. Due to the physiologic effects of initiation of ventilation prior to clamping of the umbilical cord the investigators hypothesize that initiation of resuscitation prior to umbilical cord clamping will stabilize the cardiopulmonary transition and will decrease the prevalence of LV dysfunction in this population. The results of this study will lay the foundation for a future multi-center randomized trial and are likely to impact the manner in which newborns with CDH are resuscitated after birth
