Background:
In October 2018, a respiratory care protocol (RCP) including less invasive surfactant administration (LISA), was introduced for preterm infants admitted on continuous positive airway pressure (CPAP).
Study Design:
We compared respiratory care practices and outcomes of ≥ 35-week gestational age (GA) infants between a pre-RCP (Jan 2016 to September 2018) and a post-RCP cohort (Oct 2018 to Dec 2021). Infants requiring < 24 h of CPAP and diagnosed with meconium aspiration syndrome were excluded.
Results:
Of the 260 infants meeting inclusion criteria, 126 belonged to the pre-RCP and 134 to post-RCP cohort. Compared to pre-RCP, a lower proportion of infants in the post-RCP received CPAP on admission but a higher proportion received surfactant therapy (8% vs 22%, p < 0.001). Notably, surfactant therapy was associated with lower FiO2 requirement for 24 h and respiratory severity score for 48 h in the post-RCP cohort. However, there was no difference in any of the outcomes such as the need for mechanical ventilation, incidence of pneumothorax and length of hospital stay between two cohorts.
Conclusions:
Implementing an RCP increased surfactant use with associated improvement in oxygenation but did not improve outcomes. Further studies are necessary to evaluate the role of LISA in ≥ 35-week GA infants.

Antitussives include codeine, dextromethorphan (Robitussin), and benzonatate (Tessalon). Codeine and dextromethorphan exert their effects centrally by suppressing the cough reflex center in the medulla. Benzonatate operates peripherally within the respiratory tract by...
