Trial Summary

What is the purpose of this trial?

DIVA is a pragmatic randomized clinical trial (RCT) to determine: among (P) preterm infants born 23 0/7-28 6/7 weeks gestation undergoing extubation from mechanical ventilation, whether (I) Non-invasive neurally adjusted ventilatory assist (NIV-NAVA) (C) compared with Non-synchronized nasal intermittent positive pressure ventilation (NS-NIPPV), will reduce the incidence of (O) extubation failure within (T) 5 days (120 hours) of extubation.

Will I have to stop taking my current medications?

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

What data supports the effectiveness of the treatment NIV-NAVA for extubation failure in preterm infants?

Research shows that NIV-NAVA, a treatment that helps preterm infants breathe by using signals from their diaphragm, can improve breathing after removing a breathing tube. In one study, 83% of infants had better breathing with lower carbon dioxide levels after using NIV-NAVA.12345

Is non-invasive neurally adjusted ventilatory assist (NIV-NAVA) safe for use in preterm infants?

Research on non-invasive neurally adjusted ventilatory assist (NIV-NAVA) in preterm infants suggests it is generally safe, with studies focusing on its effectiveness and adverse effects. While the evidence is less robust compared to invasive methods, no significant safety concerns have been highlighted in the studies available.12345

How is the treatment NIV-NAVA different from other treatments for extubation failure in preterm infants?

NIV-NAVA is unique because it uses the electrical activity of the diaphragm (the main muscle used for breathing) to synchronize the ventilator's support with the infant's natural breathing efforts, potentially improving breathing support and reducing the need for reintubation compared to other methods like NCPAP.12346

Eligibility Criteria

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.

Treatment Details

Interventions

  • NIV-NAVA
  • NS-NIPPV
Trial Overview This study tests if NIV-NAVA (a type of breathing support that adjusts to the baby's own breathing efforts) is better than NS-NIPPV (non-synchronized nasal ventilation) in preventing failure of extubation within five days in premature infants.

Findings from Research

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 study comparing non-invasive neurally adjusted ventilatory assist (NIV-NAVA) and nasal intermittent positive-pressure ventilation (NIPPV) in preterm infants under 30 weeks gestation, treatment failure rates were similar between the two methods, with 40% for NIV-NAVA and 47.4% for NIPPV, indicating that both methods are effective post-extubation.
NIV-NAVA was found to be safe for use in this population, showing no significant difference in adverse events compared to NIPPV, suggesting it can be a viable option for respiratory support in premature 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.
