Overview
Brief Summary
The purpose of this study is to determine if the combination of late doses of Infasurf with inhaled nitric oxide will interact to improve the surfactant function and thus the respiratory status and outcome of treated infants.
Detailed Description
Surfactant dysfunction may contribute to the development of bronchopulmonary dysplasia (BPD) in persistently ventilated preterm infants. The investigators conducted a multi-center, randomized, blinded pilot study to assess the safety and efficacy of late administration of surfactant (Calfactant - high in protein B) in combination with prolonged inhaled nitric oxide in preterm infants \< 1000 grams birthweight (BW). Calfactant is one of several types of exogenous surfactant. Calfactant has the highest % of surfactant protein B of the different types.

Arms & Interventions
Treatment Surfactant (Infasurf) ONY, NY
Patients receive inhaled nitric oxide and scheduled doses of Infasurf on study days 0, 3, 7, 10, and 14, if infant remains ventilated.
Intervention: Infasurf (ONY Inc.)
Sham (no treatment)
Infants receiving inhaled nitric oxide will receive Sham (no treatment) on study days 0, 3, 7, 10, and 14, if infant remains ventilated.
Intervention: Sham
Outcomes
Primary Outcomes
SP-B Content
Time Frame: One day after dose
SP-B Content is the surfactant protein B found in terms of percentage of phospholipid measured one day after surfactant or sham dose.
Secondary Outcomes
- Alive Without BPD at 36 Weeks Post Menstrual Age(36 Weeks Post Menstrual Age)
