Plain English summary of protocol

Background and study aims
Lung ultrasound is a non-invasive, easy and quick technique that is being increasingly used in the clinical practice worldwide. It has been proven to be very accurate to evaluate the severity of respiratory failure and the need for surfactant replacement in preterm and extremely preterm neonates. Nonetheless, it is unclear if it is equally accurate and useful to predict surfactant need in late preterm and term neonates, as they may be affected by different types of respiratory failure.

Who can participate?
Late preterm and term (i.e. beyond 34 weeks' gestation) may be enrolled in this study

What does the study involve?
The study is performed within the usual routine care in the participating centres. The results of lung ultrasound will be collected together with the data registered during the standard monitoring of these patients.

What are the possible benefits and risks of participating?
Participation in the study will be useful and bring benefits on a larger scale since it may significantly improve the management of these patients.
No test is performed solely for study purposes and and there is no risk whatsoever for the patients. On the contrary, lung ultrasound is non-invasive and is already used in clinical practice to visualise the lungs and have more insights about the respiratory disorder.

Scientific titleQuantitative lung ultrasound to predict surfactant need in late preterm and term neonates with respiratory failure
Study acronymULTRAS
Study objectivesA previously validated and well known neonatal lung ultrasound score can predict the surfactant need in late preterm and term neonates with respiratory failure in the first 72h of life with at least the same accuracy shown in preterm neonates.
Ethics approval(s)

Approved 30/06/2022, Comitato Etico per la Sperimentazione Clinica della Provincia di Padova (via Giustiniani 1, Padova, 35128, Italy; +39 498211435; luca.bonadies@unipd.it), ref: 5495/AO/22

Health condition(s) or problem(s) studiedSurfactant need in late preterm and term infants
InterventionCalculation of the lung ultrasound scores performed upon NICU admission and before surfactant administration (if any) together with the consideration of data issued of vital monitoring. Ultrasound and monitoring are performed within the routine clinical care in the participating centers (so that no test is performed solely for study purposes) and the study is pragmatically "nested" within clinical care.
Intervention typeOther
Primary outcome measureUpon NICU admission and before surfactant administration (if any):
1. Diagnostic accuracy measures (area under the ROC curve and derived accuracy variables). For these outcomes, lung ultrasound scores and need for surfactant replacement will be collected (i.e.: this will allow the raw calculation of true and false positives and negatives).
2. Additionally demographics, clinical and monitoring variables usually registered during routine care will be collected.
Secondary outcome measuresOxygenation metrics measured with usual vital monitoring available in each center and its relationship with lung ultrasound score measured using patient records upon NICU admission and before surfactant administration (if any)
Overall study start date01/06/2021
Completion date20/12/2023
