Importance A sustained inflation (SI) provided at birth might reduce bronchopulmonary dysplasia (BPD). Objective This study aims to examine whether an SI-guided exhaled carbon dioxide (ECO 2 ) compared with positive pressure ventilation (PPV) alone at birth decreases BPD. Design Randomised controlled trial. Infants were randomly allocated to either SI (SI group) or PPV (PPV group). Participants Participants of this study include infants between 23 +0 and 32 +6 weeks gestation with a need for PPV at birth. Intervention Infants randomised into the SI group received an initial SI with a peak inflation pressure (PIP) of 24 cmH 2 O over 20 s. The second SI was guided by the amount of ECO 2 . If ECO 2 was ≤20 mm Hg, a further SI of 20 s was delivered. If ECO 2 was >20 mm Hg the second SI was 10 s. Infants randomised into the PPV group received mask PPV with an initial PIP of 24 cmH 2 O. Primary outcomes Reduction in BPD defined as the need for respiratory support or supplemental oxygen at corrected gestational age of 36 weeks. Results SI (n=76) and PPV (n=86) group had similar rates of BPD (23% vs 33%, p=0.090, not statistically significant). The duration of mechanical ventilation was significantly reduced with SI versus PPV (63 (10–246) hours versus 204 (17–562) hours, respectively (p=0.045)). No short-term harmful effects were identified from two SI lasting up to 40 s (eg, pneumothorax, intraventricular haemorrhage or patent ductus arteriosus). Conclusion Preterm infants 2 to guide length of SI is feasible. Trial registration number NCT01739114; Results.
