Clinical Trial Summary

This prospective, unblinded, pilot randomized cross-over trial of 2 modes of mechanical ventilation will compare measures of pulmonary mechanics, respiratory gas exchange, and patient comfort between conventional flow triggered mechanical ventilation and neurally adjusted ventilatory assist (NAVA) among 20 prematurely born infants and young children receiving invasive respiratory support for severe bronchopulmonary dysplasia (BPD).


Description:

Most research to date in neonatal lung disease has focused on bronchopulmonary dysplasia (BPD) prevention. As a result, insufficient investigation has been performed to define optimal respiratory management strategies for infants and young children with established BPD. Thus, there is no robust evidence base to guide ventilator management to promote lung disease recovery and support neurodevelopment in this population. Neurally adjusted ventilatory assist (NAVA) is an alternative to conventional flow triggered ventilation that has shown promise for improving respiratory gas exchange, patient-ventilator interaction, and work of breathing in preterm neonates. The safety and efficacy of NAVA in infants and young children with established, severe BPD is uncertain. This prospective, unblinded, pilot randomized cross-over trial of 2 modes of mechanical ventilation will compare measures of pulmonary mechanics, respiratory gas exchange, and patient comfort between conventional flow triggered mechanical ventilation and NAVA among 20 prematurely born infants and young children receiving invasive respiratory support for severe BPD.

Intervention

Device:
NAVA
NAVA mode of mechanical ventilation provide the trigger for a spontaneous breath from the diaphragmatic movement instead of diaphragm and allows the patient to control the dynamics of the breath generally set in CMV mode.
CMV
CMV mode of mechanical ventilation that provides a trigger for a spontaneous breath from the airway flow sensor with dynamics of the breath set as required by the mode

Outcome

Type Measure Description Time frame Safety issue
Primary Oxygen saturation (SpO2) index Oxygen saturation index will be measured by assessing if invasive mechanical ventilation with NAVA compared to CMV improves respiratory gas exchange in patients receiving invasive respiratory support for BPD. This will be calculated as the median, time-weighted daily oxygen saturation (SpO2) index ([mean airway pressure x Fraction of inspired oxygen (FiO2)]/SpO2). up to 5 days per study arm
Secondary Sedation Medications The need for sedation medication will be assessed by comparing the needs for sedation by the total daily dose milligram/kilogram (mg/kg) of sedation medications on invasive mechanical ventilation with NAVA compared to CMV. up to 5 days per study arm
Secondary Stress Patient stress will be assessed by collecting salivary swabs three times per day to measure cortisol levels. The daily average will be assessed and compared as a marker for patient stress on invasive mechanical ventilation with NAVA compared to CMV. up to 5 days per study arm
