Early extubation of premature infants may limit the deleterious effects of positive pressure ventilation. The primary cause of failure of extubation (and the need for reintubation) is apnea of prematurity. Standard treatment for improving extubation success and decreasing apnea of prematurity is with the use of nasal continuous positive airway pressure (nCPAP), use of methylxanthines, or both. Recent literature suggests that methylxanthines may have significant effect on long-term neurodevelopmental outcome.
This primary objective of this study is to investigate the effect of synchronized nasal intermittent positive pressure ventilation (sNIPPV) combined with standard nasal continuous positive airway pressure (nCPAP) versus standard nCPAP alone, on the need for reintubation and the need of methylxanthine therapy in premature infants. The study period for the primary objective will be the first 7 days immediately after the initial extubation of premature infants with birth weights 500-1250 grams. A secondary objective is to identify any differences in duration of time free of endotracheal intubation and duration of time free of methylxanthine use between the two treatment modalities as measured from the first extubation attempt.
The study is a randomized, controlled trial using a new CPAP machine (Infant Flow advance™) that will be able to provide nCPAP with and without sNIPPV. Because of the mechanics of the sNIPPV mode, blinding of the study is not possible. The study is pragmatic in design allowing the medical staff to make clinical decisions on ventilatory management based on the routinely used criteria thus evaluating the study interventions in the everyday clinical environment. Analysis will be on an intention-to-treat basis.
