Description of intervention(s) / exposure
High-flow nasal cannulae (HFNC): This intervention involves delivering flow rates of gas (air/oxygen) at a minimum of 2 litres per minute via smaller nasal cannulae than those used with nasal CPAP. Infants randomised to HFNC will remain on this intervention until failure criteria or cessation criteria are met, with changes to flow rate at the discretion of the treating medical team. Infants who 'fail' (based on non-subjective clinical criteria) will be changed to nasal CPAP or re-intubated.

Comparator / control treatment
Nasal continuous positive airway pressure: This intervention is the standard treatment to be used as the comparator. Nasal CPAP involves the delivery via binasal prongs of a regulated pressure of gas (air/oxygen) to the infant. Infants randomised to nCPAP will remain on this therapy until failure or cessation criteria are met, based on non-subjective clinical criteria. Infants who 'fail' will be re-intubated.

Failure of assigned treatment within seven (7) days of extubation. Failure will be defined by non-subjective clinical criteria including: 1. respiratory acidosis with on blood gas measurement 2. increasing oxygen requirement based on peripheral transcutaneous oxygen saturation measurement 3. clinically observed worsening apnoea, or 4. any emergency deemed to require re-intubation by the treating medical team.

Nasal septum or skin trauma whilst receiving assigned treatment. A nasal trauma chart has been designed for the trial which will be completed on each nursing shift by the nurse caring for the infant. These charts will be collected and episodes of nasal trauma will be noted. Subsequent management of the nasal trauma will be noted from the patient's medical record.

Summary
Brief summary
HIPERSPACE is a trial comparing the use of two types of breathing support for premature infants after they have been extubated (come off a mechanical breathing machine) in the Royal Women’s Hospital (RWH), Adelaide Women's and Children's Hospital (WCH) or Royal Brisbane and Women's Hospital (RBWH) neonatal intensive care units. Premature infants who are born less than 32 weeks of gestation, required support from a mechanical breathing machine, and are planned to be extubated to further breathing support are eligible for inclusion in the trial. The usual way post-extubation breathing support has been provided is by using large prongs in the babies’ nose which transmit a continuous, and regulated, pressure to the baby’s lungs to help them breathe more easily. This support, called nasal CPAP, is quite bulky and requires the infant to wear a tightly-fitted hat, and sometimes causes damage to the infants’ nose. A newer form of support being used around Australian and the world is called high-flow nasal cannulae (HFNC). This method uses smaller prongs in the infant’s nose and blows gas at 2-8 litres per minute into the infant’s airway. It is thought this flow also produces a pressure that helps to keep the lungs open, and has been considered to be more comfortable for the infants. However, despite widespread use, HFNC has not been well studied in premature infants. In the HIPERSPACE trial, premature infants who have been extubated will be randomly assigned to receive either nCPAP or HFNC. The main result we will be interested in from the trial will be which treatment the infants do better on. Infants in the HFNC group who are not coping can be offered nCPAP as ‘rescue’ treatment. Information will be collected about the infants until they are discharged from hospital, including the incidence of lung complications, the amount of different types of breathing support required, rates of complications from using the different types of prongs in the nose, and the comfort of the infant.
