Detailed Description
We propose to pilot the use of this mobile nHF unit, using the Vapotherm Precision Flow device, in the premature population of babies who would normally be either intubated and given surfactant routinely, or be maintained on nCPAP until arrival on the Neonatal Intensive Care Unit (NICU) then transferred onto nHF. Parents will be informed about the pilot and their permission will be sought. We aim to recruit 40 babies less than 30 weeks gestation.
The reason for undertaking a pilot study of this nature is to establish feasibility and proof of concept. It is not designed to be compared to using nCPAP to stabilise babies immediately after birth (although that will be the next and logical progression if this proves to be a feasible technique).
The hypothesis is that using nHF to stabilise babies immediately after birth will confer the same advantages as using nCPAP to stabilise babies in this way, which has been demonstrated in the worldwide literature. For units such as ours who use nHF in preference to nCPAP, this will be an important step in further defining the management of these babies after birth. There is evidence that nHF is at least as good as nCPAP in preventing intubation and reducing lung disease, and it may also offer additional advantages from humidification and reduction in nasal trauma.
The major challenge for this pilot project will be to identify eligible deliveries in a timely manner to ensure that a suitable member of staff is available to speak to parents and gain consent.
Once a delivery has been identified and the parents have agreed to take part, then the following process will take place to manage the newborn baby.
Check the mobile nHF unit
- The mobile nHF unit should be kept plugged in so that the uninterruptable power supply (UPS) is fully charged
- To use it, unplug it to check that the UPS is functioning (green lights indicate full charge), set up a Vapotherm circuit(as per normal routine) and start the machine running on UPS power supply.
- Gas supply should be from the cylinders to check that the pressures are 50bar in both air and oxygen cylinders
- Set the temperature to 37 degrees Celsius
- Once running, turn the unit off if not immediately needed or plug into the mains power and gas(es) where available to conserve gas. The unit can be run on a flow of 1 litre/minute whilst "ticking over" to conserve cylinder gas if needed.
- The prongs should be attached to the circuit.
Once the baby is born
- Place the baby in a polythene bag (as per normal practice)
- Ensure the baby is breathing. If not, or the baby is bradycardic, then normal resuscitation measures should be applied. It will only be appropriate to apply the mobile nHF if the baby is breathing and is clinically stable.
- Once the baby is born, increase the flow to 6 litres/min
- If the baby is breathing then apply the nHF prongs and observe carefully
- Suction should only be applied gently, if needed to remove excessive secretions in the mouth and throat. Babies on high flow will often "blow bubbles" and there may be lung fluid in the throat, but suction should not be vigorous
- Apply a saturation monitor (as per normal practice) to check Heart Rate (HR) and Oxygen Saturation (SaO2).
- Dry the baby's face sufficiently to be able to apply duoderm dressing to stick down the prongs to the cheeks.
- Observe the baby carefully, ensure attention to thermal care and inform the parents about progress.
- As soon as the baby appears stable, move to NICU as per normal practice
Transfer to NICU
- Two people are needed to effect the transfer from labour ward/theatre to NICU, one to move the mobile nHF and one to move the resuscitaire.
- On arrival in NICU, plug the mobile nHF into gas and power supplies (switch the manifold over)
- Ensure that there is a second, cotside Vapotherm (empty) unit
- Leave the baby in the resuscitaire and check the admission temperature.
- Stop the mobile nHF, remove the cartridge and place it into the cotside Vapotherm unit. Start it running, it should run straight away. Ensure that the correct temperature, flow and Fraction Of Inspired Oxygen (FiO2) are set
- This process takes less than 20 seconds and as the baby is breathing will not be detrimental
- Transfer the baby into the incubator and commence normal admission practices
- Document the resuscitation clearly in the baby's notes
Cleaning and charging the mobile nHF
o Remove the mobile nHF, clean the Vapotherm Precision flow nHF unit. Ensure the cylinders are switched off and plug into the wall to recharge the UPS.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Need for endotracheal intubation prior to admission to Neonatal Unit
Time Frame: From birth
|
Babies who are clinically stable will not require intubation prior to admission to the neonatal unit.
|
From birth

Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Development of pneumothorax within 24 hours of birth
Time Frame: First 24 hours after birth
|
Pneumothorax is a rare but important outcome measure.
|
First 24 hours after birth
|
Requirement for endotracheal intubation and surfactant administration after admission to neonatal unit within 24 hours of birth
Time Frame: First 24 hours after admission to neonatal unit
|
Intubation and surfactant administration after admission within the first 24 hours indicates severe respiratory distress syndrome requiring treatment according to agreed local protocols
|
First 24 hours after admission to neonatal unit
|
Development of bronchopulmonary dysplasia defined as oxygen requirement at 36 weeks corrected age
Time Frame: Defined at 36 weeks corrected age
|
Bronchopulmonary dyplasia is an important outcome of the respiratory management of premature babies.
We use the standard definition of an ongoing oxygen requirement at 36 weeks corrected age with compatible X-ray changes.

Defined at 36 weeks corrected age
