简要总结
To investigate whether nasal high frequency oscillation ventilation (nHFOV) immediately after extubation reduces the arterial partial pressure of carbon dioxide (paCO2) at 72 hours after extubation in comparison with nasal continuous positive airway pressure (nCPAP) in very low birth weight infants (VLBWs).
详细描述
Randomized controlled clinical trial comparing nHFOV vs nCPAP immediately after extubation of VLBW infants.
Intervention and treatment protocol as described for the two study arms.
Definition of treatment failure (infant meets at least one criterion):
- Sustained pCO2 >80 mmHg and pH <7.20 confirmed by arterial or capillary blood gas analysis in spite of optimized non-invasive respiratory support with maximum settings as defined above.
- Fraction of inspired oxygen (FiO2) >0.6 to maintain peripheral oxygen saturation as measured by pulse oximetry (SpO2) at 90-94% in spite of optimized non-invasive respiratory support with maximum settings as defined above.
- Reintubation (study patients may be intubated at any time, due to clinical considerations, with or without reaching another criterion of "treatment failure").
