Trial Review

Please note the ANZCTR will be unattended from Friday 20 December 2024 for the holidays. The Registry will re-open on Tuesday 7 January 2025. Submissions and updates will not be processed during that time.

To achieve prospective registration, we recommend submitting your trial for registration at the same time as ethics submission.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Description of intervention(s) / exposure
In the AIRPREMO Study, a modified TGA approved dual lumen nasogastric tube (initially only 8 French in size; after participant 16, with Ethics Committee approval, either 6 French or 8 French in size, depending on the participant's weight and as per preference of the clinical team) is used to measure deep oropharyngeal air pressure of babies who receive non-invasive respiratory support (either through continuous positive airway pressure or through high flow nasal cannulae). Measurements are obtained with this research data collection system for up to one hour and data will inform the development of a new device.
Intervention code [1] 325259 0
Not applicable
Comparator / control treatment
The study does not have a control group. For participants on CPAP, the set CPAP pressures will be the comparator for the measured airway pressure and the comparisons will be processed over a total of up to one hour (rolling average). For high-flow participants, the measured pressures (rolling average) over one hour will be related to the set high flow rate.
Control group
Active

Outcomes
Primary outcome [1] 333664 0
For CPAP: Mean oropharyneal pressure [from the modified nasogastric tube] compared to the set pressure from CPAP.
Timepoint [1] 333664 0
At end of recording period (up to one hour)
Primary outcome [2] 333819 0
For high-flow: Mean oropharyneal pressure [from the modified nasogastric tube] compared to set high flow rate
Timepoint [2] 333819 0
At end of recording period (up to one hour)
Secondary outcome [1] 417887 0
User acceptability feedback from nursing staff observing the study intervention.
Timepoint [1] 417887 0
Completion of questionnaire (specifically designed for this study and HREC approved) at end of the one hour study period
Secondary outcome [2] 418423 0
Effects of newborn behavior (movement, crying etc) on observed oropharyngeal pressures. A variety of newborn behavious (such as movement, yawning, crying, etc.) will be recorded as timed log by the researcher.
Timepoint [2] 418423 0
End of one hour study period

Statistical methods / analysis
As deep oropharyngeal pressures are measured over a one-hour period, the mean pressures will be determined. For CPAP, which has a set pressure, the mean pressure will be compared to the set pressure. For high flow the measured pressures will be correlated with the set flows. Pressure fluctuations will be correlated with a number of observed variables (bubbling, participant behaviours, movement etc). The range of measured pressures will be determined. As this is a proof-of-concept study, focus is on observations rather than formal statistical analysis.
