Non-invasive Neurally Adjusted Ventilatory Assist Versus Nasal Intermittent Positive Pressure Ventilation for Preterm Infants After Extubation: A Randomised Control Trial

Non-invasive respiratory support has been emerging in the management of respiratory distress syndrome (RDS) in preterm infants to minimise the risk of lung injury. Intermittent positive pressure ventilation (NIPPV) provides a method of augmenting continuous positive airway pressure (CPAP) by delivering ventilator breaths via nasal prongs.It may increase tidal volume, improve gas exchange and reduce work of breathing. However, NIPPV may associate with patient-ventilator asynchrony that can cause poor tolerance and risk of intubation. It may also in increased risk of pneumothorax and bowel perforation because of increase in intrathoracic pressure.

On the other hand, neurally adjusted ventilatory assist (NAVA) is a newer mode of ventilation, which has the potential to overcome these challenges. It uses the electrical activity of the diaphragm (EAdi) as a signal to synchronise the mechanical ventilatory breaths and deliver an inspiratory pressure based on this electrical activity. Comparing NI-NAVA and NIPPV in preterm infants, has shown that NI-NAVA improved the synchronization between patient and ventilator and decreased diaphragm work of breathing .

There is lack of data on the use of NI-NAVA in neonates post extubation in the literature. To date, no study has focused on short-term impacts. Therefore, it is important to evaluate the need of additional ventilatory support post extubation of NI-NAVA and NIPPV and also the risk of developing adverse outcomes.

Aim:

The aim is to compare NI-NAVA & NIPPV in terms of extubation failure in infants< 32 weeks gestation.

Hypothesis:

Investigators hypothesized that infants born prematurely < 32 weeks gestation who extubated to NI-NAVA have a lower risk of extubation failure and need of additional ventilatory support.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4.

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Treatment failure
Time Frame: 72 hours
  1. Treatment failure during the first 72 hours post-extubation.
  2. Reintubation (failure of extubation) within 72 hours' post extubation.
