Study type
Interventional
Description of intervention(s) / exposure
This is a non-randomised three arm study. Group 1 will consist of babies who receive AeroFactTM. Group 2 will be babies who would have met criteria for AeroFactTM treatment but who remain on nCPAP only (“usual care” controls). Group 3 will comprise babies who are on nCPAP but are deemed by their treating clinicians to need intubation and endotracheal surfactant administration. Enrolment will continue sequentially until 10 infants are recruited in group 1, then 20 infants in group 2. Meanwhile, group 3 infants can be recruited at any time during the duration of the study. Lung function will be measured using electrical impedance tomography (EIT) and lung ultrasound and physiological measurements will be taken from prior to surfactant instillation and every 30 minutes until 2 hours post surfactant (or equivalent time in the CPAP only group) by the research nurse. The EIT belt will be placed around the circumference of the chest prior to surfactant instillation and remain for the 2 hour duration of the measurement period with measurements. A 3 minute EIT measurement will be taken prior to surfactant instillation, and then every 30 minutes for 2 hours.

Statistical methods / analysis
The sample size will be 40 infants in total. Group 1 and 3 will have 10 infants each (20 total). Group 2 will have 20 infants which will allow a 2:1 control for Groups 1 and 3. This is an exploratory proof of concept study to describe lung distribution with two types of surfactant delivery (standard liquid bolus versus aerosol) with a control group not receiving surfactant, a power calculation has not been performed. The sample size of 40 is deemed appropriate for a proof of concept, descriptive study, and has been sufficient to demonstrate statistically and clinically significant changes in lung aeration and regional ventilation in other studies of NICU care.
Results will be described using mean and confidence intervals (CI), or standard deviations (SD) for the biometric data. To account for missing data, mixed linear models (MLM) will be used to analyse the impact of surfactant administration on EEL, regional ventilation distribution and physiological variables in each of the three groups. Post hoc analysis will use ANOVA with Bonferroni correction. A p-value of < 0.05 will be considered significant. All statistical analyses will be performed using SPSS (v15.0, Lead Technologies, Inc., Chicago, IL, USA).

Summary
Brief summary
Respiratory Distress Syndrome (RDS) in the newborn is caused mainly by a deficiency in pulmonary surfactant and is a major cause of morbidity and mortality among preterm infants. The distribution of surfactant within the lungs and the correlation with physiological responses when using it have not been previously assessed in human infants. Electrical Impedance Tomography (EIT) is a safe, non-invasive technique that can be used in preterm infants to provide valuable physiological data about regional lung aeration. Therefore, the purpose of this study is to use EIT to examine the distribution of ventilation within the lungs after surfactant administration (either a bolus via ETT or nebulised via nCPAP) and compare with a group who do not require surfactant.
