  Purpose
Neonates who underwent cardiac surgery with cardiopulmonary bypass almost always require non-invasive respiratory support (NIV) in relay to conventional ventilation. Current nasal interfaces do not generally allow synchronised bilevel ventilation. NIV-NAVA mode allows, through an oesophageal catheter, to record the electrical activity of the diaphragm and thereby synchronize breaths from the ventilator on the inspiratory efforts of the child. Moreover, the pressure support delivered by the ventilator may be proportional to the diaphragmatic effort developed by the child. This mode, associated with the interface Miniflow®, could increase the comfort of the child by allowing a more efficient synchronization and reducing its respiratory work. To our knowledge, this ventilation mode with this interface has not been evaluated in the postoperative period of cardiac surgery in the newborns. The purpose of this study is to evaluate the feasibility of this ventilatory mode and evaluate its influence on ventilatory parameters of this category of infants.

Primary Outcome Measures:
  • Evaluation of the percentage of asynchronies during the nava mode [ Time Frame: from minute zero to minute 90 ]
    One of the aims of the NAVA mode is to provide better synchronization between the child's breathing needs and the breathing cycles given by the ventilator. By comparing the EDI curve (electric activity of the diaphragm of the child) and the flow and pressure curves of the ventilator, it is possible to determine the percentage of asynchronies during the nava mode


Secondary Outcome Measures:
  • Comparison of breathing rhythm between nasal Continuous Positive Airway Pressure (nCPAP) mode and NIV-NAVA mode [ Time Frame: from minute zero to minute 90 ]
  • Comparison of PEEP (positive end expiratory pressure) between nasal Continuous Positive Airway Pressure (nCPAP) mode and NIV-NAVA mode [ Time Frame: from minute zero to minute 90 ]
  • Comparison of Inspiratory Pressure between nasal Continuous Positive Airway Pressure (nCPAP) mode and NIV-NAVA mode [ Time Frame: from minute zero to minute 90 ]
  • Comparison of FiO2 between nasal Continuous Positive Airway Pressure (nCPAP) mode and NIV-NAVA mode [ Time Frame: from minute zero to minute 90 ]
  • Comparison of PaO2 between nasal Continuous Positive Airway Pressure (nCPAP) mode and NIV-NAVA mode [ Time Frame: from minute zero to minute 90 ]
  • Comparison of PaCO2 between nasal Continuous Positive Airway Pressure (nCPAP) mode and NIV-NAVA mode [ Time Frame: from minute zero to minute 90 ]
  • Comparison of blood pH between nasal Continuous Positive Airway Pressure (nCPAP) mode and NIV-NAVA mode [ Time Frame: from minute zero to minute 90 ]
