Plain English summary of protocol

Background and study aims
Lung ultrasound predicts surfactant administration in neonates with moderate respiratory distress syndrome stabilized on continuous positive airway pressure (CPAP), but whether this is true for more critical infants is unknown. The objective of this study is to assess whether lung ultrasound may also predict surfactant replacement in infants on different respiratory support over a wide range of mean airway pressure.

Who can participate?
Neonates with respiratory distress in the first 2 hours of life stabilized with different techniques of respiratory support.

What does the study involve?
This study is a pragmatic, observational study set in Italian and Spanish neonatal intensive care units

What are the possible benefits and risks of participating?
It is hoped that future patients will benefit from the findings that lung ultrasound allows an early and targeted surfactant replacement.
Neonates participating in the study have no possible risks because they will not undergo new procedures because of the study itself. It is an observational study without interventions on patients.

Where is the study run from?
University of Naples Federico II (Italy). Neonatology Section

When is the study starting and how long is it expected to run for?
January 2022 to May 2025

Who is funding the study?
University of Naples Federico II (Italy)

Who is the main contact?
Prof Francesco Raimondi, raimondi@unina.it (Italy)

Scientific titleDoes lung ultrasound predict surfactant administration in neonates with respiratory distress stabilized with different support techniques? An international, pragmatic study
Study acronymLUSVENT
Study objectivesLung ultrasound accurately predicts surfactant administration in neonates with respiratory distress syndrome stabilized on CPAP. However, whether this is true for more critical infants stabilized with non-invasive or invasive ventilation is unknown. The objective of the study is to assess whether lung ultrasound may also predict surfactant replacement in infants on different respiratory support over a wide range of mean airway pressure
Ethics approval(s)

Approved 11/02/2022, Comitato Etico Universita’ Federico II (Via Pansini 5, Napoli, 80131, Italy; +39 081 746 2596; segreteria@comitatoeticocampania3.it), ref: 386/21

Health condition(s) or problem(s) studiedAccuracy of lung ultrasound score to predict surfactant administration in neonates with respiratory distress stabilized with different support techniques
InterventionThe lung ultrasound score will be obtained for three groups of neonates with respiratory distress, stabilized on continuous positive airway pressure (CPAP), non-invasive ventilation and invasive ventilation within 2 hours of life. The result of the score will be carefully concealed from the attending physician evaluating the later need for surfactant administration. The predictive accuracy for surfactant of the lung ultrasound score alone or with non-invasive variables will be investigated according to the different respiratory support techniques. After the lung ultrasound at the enrolment, participants will receive a lung ultrasound at 7 days of life and 36 weeks of gestational age. Data relating to general prenatal and neonatal characteristics, respiratory support, oxygen supplementation, onset of complications of prematurity will be monitored and collected until discharge from NICU.
Intervention typeOther
Primary outcome measureThe predictive accuracy of the lung ultrasound score of surfactant therapy measured using the Brat Score in the first 2 hours of life
Secondary outcome measures1. The prognostic accuracy for surfactant administration measured using data collected from patient medical record in the whole population and the three groups of the following individual predictors at enrolment, 7 days and 36 weeks of gestational age:
1.1. SatO2/ FiO2
1.2. FiO2>0.3
1.3. OSI index
2. The prognostic accuracy for surfactant administration in the whole population of a previously developed logistic regression model based on lung ultrasound according to the Brat Score, gestational age, with/without oxygenation indexes evaluated at the enrolment.
3. The clinical trajectory and outcome of infants stabilized with techniques other than CPAP evaluating the progression of lung ultrasound score and oxygenation indexes at enrolment, 7 days and 36 weeks of gestational age and evaluating need and duration of oxygen and respiratory support, diagnosis of bronchopulmonary dysplasia and death at the end of NICU staying.
