Background:

Non-synchronized nasopharyngeal ventilation (VNFns) and continuous positive pressure of the nasal airway (CPAPn) are methods of non-invasive ventilatory support.

Objective:

To compare the efficacy of the two methods as an extubation and rescue strategy.

Material and methods:

Patients who had been in one of both strategies from 2008 to 2012, categorizing them as extubation or rescue and measuring success or failure.

Results:

Success as an extubation strategy was 83.3% for VNFns against 68.7% for CPAPn (OR: 2.26). There was a difference for VNFns, in relation to hospitalization days, with a mean of 38.6 versus 65.4 days (p = 0.0001). Regarding bronchopulmonary dysplasia, there was a decreased risk (OR: 0.64; p = 0.01) for VNFns. There was a higher number of complications for CPAPn, columella injury, pneumomediastinum, pneumothorax and nasal bleeding. Hypocarbia was more frequent in VNFns.

Conclusion:

VNFns was shown to be an effective and safe strategy, compared to CPAPn.
