Description of intervention(s) / exposure

Neonates born between 22+0 weeks’ gestation and term gestation admitted to a participating centre needing assisted respiratory support for any cause of respiratory failure in whom prospective parental informed consent can be obtained will be considered eligible. Measurements of lung function will be made using electrical impedance tomography (EIT) at different times in their neonatal intensive care journey. These measurements will be made over 30-60 min of stable respiratory support after any change in mode or type of respiratory support and during procedures and treatments likely to alter respiratory function (surfactant therapy, extubation and intubation). For neonates requiring an anticipated NICU course of 4 or more weeks, weekly assessment of lung function will be made. The maximum duration of observation (EIT imaging) will be until birth or 36 weeks corrected post-menstrual age whichever is longest.

Can healthy volunteers participate?

No

Key exclusion criteria

Participants meeting any of the following criteria will be excluded from this study:
1. Any neonate whom the clinical team request we do not study.
2. Neonates in whom the placement of EIT belt at the standard position (nipple level) would interfere with clinical care, such as wound dressings, surgical sites or chest drains.
3. Neonates with known or suspected skin disease (e.g. Epidermolysis Bullosa) or at risk of breeches to skin integrity from wearable monitoring devices.
4. Families from which informed written consent cannot be obtained.

Statistical methods / analysis

This study aims to enrol as many neonates as practice over the 5-year study period (convenience sample). Based on admission data for all Level 6 NICU in Melbourne for 2021-22 (750 infants per annum) this is likely to represent a minimum of 250-350 infants assuming a <10% recruitment rate and a maximum of 1000 infants (30% recruitment rate). From this sample population different analysis for specific study aims will be undertaken.

Continuous data will be analysed either with descriptive statistics or with a mixed-effects linear regression model, with robust standard error and cluster analysis to adjust for multiple breaths from each neonate.

Summary

Brief summary

Respiratory disease is the most common reason for admission to a NICU. Unfortunately, our understanding of how many respiratory therapies used in the NICU help babies lungs is poor. Broadly, we will create a large registry of lung function data during common NICU respiratory events and diseases. By doing so we will be able to address some of the uncertainties in clinical care for babies born with respiratory failure, specifically how best to determine optimal levels of respiratory support and how to guide common respiratory interventions such as extubation and surfactant therapy. We hypothesise that by generating a greater understanding of the relationship between a baby's lung disease and NICU respiratory care we will provide the tools to allow clinicians to improve respiratory care.
