Plain English Summary
Background and study aims
This study is about babies born two to six weeks before their due date. Babies born even a few weeks early are not fully developed. These babies may have breathing problems after birth, which can be severe. Some need to go onto a breathing machine (ventilator) soon after birth; others do not, but still need some help with breathing. They often go onto ‘non-invasive’ breathing support, which means that machines give oxygen through soft, short tubes in the nose or small masks over the nose.
The lungs of healthy full term babies produce surfactant, a substance that makes it easier for them to breathe. Babies born early often do not make enough surfactant, or their natural surfactant does not work properly. The researchers can give a dose of surfactant into the lungs- down a small tube in the windpipe and many of the most premature babies are given it routinely. In babies born closer to term it is harder to predict who will need surfactant and who will get better without it.
There have been no research studies in babies born two to six weeks early with breathing problems. The researchers want to know if it is better to give surfactant early, when a baby first starts to need help with breathing, or wait to see if they improve without it.
Who can participate?
Babies born at 34+0 – 38+6 weeks of gestation, with respiratory distress.
What does the study involve?
Infants born 2-6 weeks early needing non-invasive respiratory support will be randomly allocated to receive either early surfactant therapy or expectant management. Infants allocated to the early surfactant therapy will receive a single dose of surfactant. For those infants allocated to the other arm, doctors will wait to see how their breathing responds to standard care. Infants in either arms may receive an additional dose of surfactant later on, if the doctor feels it is necessary.
The researchers will collect some information such as duration of stay in hospital, duration of non-invasive support, breast milk feeding etc about the mother and infant their from medical records. The mother will be asked to fill in a short questionnaire after they provide consent and just before their infant leaves the hospital. The researchers will also keep a record of any hospital visits the infant has in their first year through routine NHS data.
What are the possible benefits and risks of participating?
Whilst there may not be any direct benefit in taking part in the study, your participation will be invaluable to help improve future care for these babies. Surfactant is routinely used in babies and there are no extra risks involved from taking part in the study.

| Scientific title | Multicentre, open-label, randomised controlled trial of early surfactant therapy versus expectant management in late preterm and early term infants with respiratory distress |
| Study acronym | SurfON |
| Study hypothesis | The aim is to investigate whether, in late preterm and early term infants with respiratory distress, the early use of surfactant versus expectant management, results in a shorter duration of hospital stay and fewer infants who fail to respond to treatment. |
| Ethics approval(s) | Approved 14/02/2020, East Midlands - Derby Research Ethics Committee (The Old Chapel, Royal Standard Place, Nottingham, NG1 6FS, UK; +44 (0)207 1048098; NRESCommittee.EastMidlands-Derby@nhs.net), ref: 20/EM/0003 |
| Condition | Respiratory and cardiovascular disorders specific to the perinatal period |
| Intervention | This is a randomised controlled trial. Infants born 2-6 weeks early needing non-invasive respiratory support will be randomly allocated to receive either early surfactant therapy or expectant management. Infants allocated to the early surfactant therapy will receive a single dose of surfactant. For those infants allocated to the other arm, doctors will wait to see how their breathing responds to standard care. Infants in either arms may receive an additional dose of surfactant later on, if the doctor feels it is necessary. The researchers will collect some information such as duration of stay in hospital, duration of non-invasive support, breast milk feeding etc about the mother and infant their from medical records. The mother will be asked to fill in a short questionnaire after they provide consent and just before their infant leaves the hospital. The researchers will also keep a record of any hospital visits the infant has in their first year through routine NHS data. |

Need for Extra-corporeal membrane oxygenation (ECMO) 11. Medical respiratory diagnoses, defined as any respiratory diagnosis attributed to the infant 12. Surfactant administration, defined as (a) administration of any additional surfactant in infants randomised to receive early surfactant or (b) administration of any surfactant in infants receiving expectant management, including number of doses and dose given 13. Maternal length of hospitalisation, defined as the total number of days spent by the mother in hospital after trial entry Health economics outcomes measures: 14. Cost of maternal hospitalisation 15. Self-reported maternal health-related quality of life 16. Costs associated with neonatal care 17. Paediatric secondary care use and associated costs using routine national databases such as Hospital Episode Statistics (HES) data |
