What is the purpose of this trial?

This trial explores two methods to help very premature infants breathe better after removal from a breathing machine. The goal is to determine whether a method using technology to match the baby's natural breathing rhythm (NIV-NAVA, a type of ventilatory support) is more effective than a commonly used method (NS-NIPPV, another form of ventilatory support) in preventing breathing problems during the first five days after tube removal. The trial seeks infants born between 23 and 28 weeks who were on a ventilator within their first week of life and are now ready to attempt breathing independently. As an unphased trial, this study provides a unique opportunity to contribute to important research that could enhance breathing support for future premature infants.

Will I have to stop taking my current medications?

The trial information does not specify whether participants must stop taking their current medications.

What prior data suggests that these ventilatory support methods are safe for preterm infants?

Previous studies have shown that the non-invasive neurally adjusted ventilatory assist (NIV-NAVA) is well-tolerated by preterm infants. Research indicates that this method helps the ventilator synchronize with the infant's natural breathing, potentially reducing the risk of extubation failure, which is the need to return to the ventilator after removal.

For non-synchronized nasal intermittent positive pressure ventilation (NS-NIPPV), studies have generally found it safe and effective for aiding preterm infants' breathing. NS-NIPPV is commonly used in medical settings and has FDA approval for this purpose.

Both treatments have been studied in infants, with safety supported by past research and clinical experience. However, individual responses can vary, so any concerns should be discussed with the healthcare providers involved in the trial. ^{1 2 3 4 5}

Why are researchers excited about this trial?

Researchers are excited about these ventilatory support methods for preterm infants because they offer innovative ways to assist breathing. NIV-NAVA is unique because it synchronizes with an infant's own breathing efforts, providing a more personalized approach to respiratory support. This contrasts with the standard NS-NIPPV, which delivers breaths at set intervals without syncing with the infant's breathing pattern. By aligning with the infant's natural respiratory drive, NIV-NAVA has the potential to improve comfort and effectiveness, reducing the risk of extubation failure.

What evidence suggests that these ventilatory support methods are effective for extubation failure in preterm infants?

This trial will compare two methods of ventilatory support for extubation failure in preterm infants: NIV-NAVA and NS-NIPPV. Previous studies have shown that NIV-NAVA, a type of breathing support that adjusts to a baby's own breathing efforts, may improve outcomes for preterm infants and reduce the need for more invasive procedures like intubation. In contrast, NS-NIPPV, another type of breathing support, is commonly used but hasn't consistently outperformed other methods like NCPAP (a steady airflow support) in preventing the need to reinsert breathing tubes. Both methods have FDA approval and are widely used, but NIV-NAVA might better match the infant's breathing, potentially reducing the need for reintubation. This trial aims to provide direct comparisons to determine which method is more effective in preventing reintubation in preterm infants. ^{1 2 4 6 7}

Are You a Good Fit for This Trial?

The DIVA trial is for preterm infants born between 24 and 27 weeks who were intubated within their first week of life. They must be less than 28 days old when extubated after at least 12 hours on a ventilator. Infants under 500 grams, without consent, needing surgery soon, or with certain health issues can't join.

Inclusion Criteria

I was put on a breathing machine within my first week of life.

I have been on a breathing machine for over 12 hours and am about to be taken off.

The baby is born between 24 and 27 6/7 weeks of pregnancy.

Exclusion Criteria

I have esophageal bleeding or a condition that prevents NG/OG tube placement.

Informed consent not provided

You were born with major birth defects, like underdeveloped lungs.

Published Research Related to This Trial

In a study of 78 preterm infants born at less than 30 weeks of gestation, noninvasive neurally adjusted ventilatory assist (NIV-NAVA) significantly reduced the rate of extubation failure within 72 hours compared to nasal continuous positive airway pressure (NCPAP), with failure rates of 8.6% for NIV-NAVA versus 28.6% for NCPAP.

NIV-NAVA also showed lower electrical activity of the diaphragm (Edi) values at 4, 12, and 24 hours post-extubation, suggesting better respiratory support and efficiency compared to NCPAP.

Noninvasive Neurally Adjusted Ventilation in Postextubation Stabilization of Preterm Infants: A Randomized Controlled Study. Shin, SH., Shin, SH., Kim, SH., et al.[2023]

In a retrospective study of preterm infants at high risk for reintubation, the use of noninvasive neurally adjusted ventilatory assistance (NIV-NAVA) significantly reduced reintubation rates within 72 hours after extubation compared to traditional nasal continuous positive airway pressure (NCPAP) (11.7% vs. 50.0%, p < 0.02).

Despite a longer duration of invasive mechanical ventilation before extubation in the NIV-NAVA group (12.4 days vs. 5.5 days, p < 0.04), there were no significant differences in secondary outcomes such as bronchopulmonary dysplasia (BPD) rates or other complications, suggesting that NIV-NAVA may be a safer and more effective option for these vulnerable infants.

Non-invasive neurally adjusted ventilatory assist versus nasal intermittent positive-pressure ventilation in preterm infants born before 30 weeks' gestation. Yonehara, K., Ogawa, R., Kamei, Y., et al.[2018]

In a study involving 15 preterm infants, neurally adjusted ventilatory assist (NIV-NAVA) demonstrated significantly better patient-ventilator synchrony compared to non-invasive pressure support (NIV-PS), with a much lower trigger delay and reduced asynchrony events.

NIV-NAVA also resulted in less diaphragmatic effort and lower peak inspiratory pressures, indicating it may provide more effective support for preterm infants during non-invasive ventilation, even with large air leaks.

In a study comparing noninvasive ventilation methods for preterm infants, those using neurally adjusted ventilatory assist (NIV-NAVA) had a significantly lower extubation failure rate (6.3%) compared to those on nasal continuous positive airway pressure (NCPAP) (37.5%).

Both groups had similar respiratory severity scores and ventilation parameters at extubation, suggesting that NIV-NAVA may provide a more effective stabilization method post-extubation for preterm infants.
