Objectives To assess whether late surfactant treatment of extremely low gestational age newborn (ELGAN) infants requiring ventilation at 7–14 days, who often have surfactant deficiency and dysfunction, safely improves survival without bronchopulmonary dysplasia (BPD). Study design ELGAN infants (≤ 28 0/7 weeks) who required mechanical ventilation at 7–14 days were enrolled in a randomized, masked controlled trial at 25 US centers. All infants received inhaled nitric oxide (INO) and either surfactant (calfactant/Infasurf®) or sham instillation every 1–3 days to a maximum of 5 doses while intubated. The primary outcome was survival at 36 weeks postmenstrual age (PMA) without BPD, evaluated by physiologic oxygen/flow reduction. Results Between January 2010 and September 2013, 511 infants were enrolled. There were no differences between treatment groups in mean birth weight (701±164 g), gestational age (25.2±1.2 weeks), percentage <26 weeks (70.6%), race, sex, severity of lung disease at enrollment, or co-morbidities of prematurity. Survival without BPD was not different between treated vs. controls at 36 weeks PMA (31.3% vs. 31.7%; relative benefit 0.98 (95% CI: 0.75, 1.28 p=0.89) or 40 weeks (58.7% vs. 54.1%; relative benefit 1.08:0.92, 1.27 p=0.33). There were no differences between groups in serious adverse events, co-morbidities of prematurity, nor in the severity of lung disease to 36 weeks. Conclusions Late treatment with up to 5 doses of surfactant in ventilated premature infants receiving iNO was well tolerated but did not improve survival without BPD at 36 or 40 weeks. Pulmonary and neurodevelopmental assessments are ongoing.

Spontaneous nonhypertensive ICH is a rare, fatal event in the ICU. Associated factors include thrombocytopenia, the need for mechanical ventilation, elevated PIP and PaCO2, sepsis, and impaired hepatic and renal function.
