Abstract
The aerosolized calfactant decreased the need for intubation in neonates with respiratory distress syndrome (AERO-02 trial). To determine the oxygenation response to aerosolized calfactant among infants born 28 0/7-36 6/7 weeks with RDS in the AERO-02 trial. Trends in hourly fraction of oxygen (FiO2), mean airway pressure (MAP) and respiratory severity score (RSS) were compared between the aerosolized calfactant (AC) and usual care (UC) groups from time of randomization for 72 h. A total of 353 subjects were included in the study. FiO2, MAP, and RSS were lower in the UC group. FiO2 decrease was seen after the first aerosolized calfactant dose. FiO2, MAP, and RSS were lower in the UC group. This is likely due to early and higher rate of liquid surfactant administration in the UC group. Decrease in FiO2 was noted in the AC group after the first aerosolization.
