Study information
Scientific title
Comparison of effectiveness two Infant Flow modes (Biphasic tr vs NCPAP) in treatment infants ≤ 1250g. A multicentre, randomised controlled trial
Acronym
NRSPRCT3
Study hypothesis
To compare the efficacy and safety of treatment using two Infant Flow modes (Biphasic tr and NCPAP) in two different study groups of very low birth weight (VLBW) infants (elective to avoid intubation and weaning from mechanical ventilation after surfactant).
Ethics approval
Bioethical Committee of the Medical University of Silesia, Katowice, Poland, approved on the 10th July 2008 (ref: KNW/6501-114/08)

Condition
Neonatal Diseases: Respiratory
Intervention
Newborns weighing between 500-1250g with a gestational age 32 weeks or less, will be categorised into elective or weaning study group and randomly assigned to one of the Infant Flow mode (Biphasic tr or NCPAP ) in first six hours of life. Infants that meet criteria for intubation and surfactant will be assigned to the weaning arm of the study. Infants that not meet intubation criteria but required respiratory support within six hours of delivery will be enrolled in the elective arm of the study. Extubation failure in the weaning group is defined as the need for reintubation and mechanical ventilation for any reason within 72 hours of initial extubation.
Treatment failure in the elective group is defined as need for intubation in the first 3 days after first weaning from nCPAP.
Secondary endpoints include: mortality, survival without broncho-pulmonary dysplasia (BPD) or chronic lung disease (CLD), number of days on CPAP, number of days on mechanical ventilation, days on supplemental oxygen, pneumothorax, nasal complications, severe intraventricular hemorrhage, periventricular leukomalacia, retinopathy of prematurity, necrotizing enterocolitis, patient ductus arteriosus and the length of hospital stay.
The sites will be visited regularly by Study Monitors. A database of the results will be maintained by an independent data centre. The results of the study will be blinded to the Investigators, but review every 6 months by an independent Data Safety Monitoring Board according to specific criteria. Prospective power calculations indicated the need for 552 infants to be enrolled. Infants will be followed up until hospital discharge or death.
