Point of Care Lung Ultrasound in Preterm Infants With Respiratory Distress
Point of Care Lung Ultrasound in Preterm Infants With Respiratory Distress: A Multicenter Prospective Study

Intervention / Treatment
Detailed Description
This is a multicenter study including preterm infants born less than 32 weeks gestational age and with a diagnosis of respiratory distress syndrome (RDS). Our primary aim is to determine the ability of lung ultrasounds performed in the first month of life to predict the development of bronchopulmonary dysplasia (BPD) at 36 weeks postmenstrual age.
Secondary aims will evaluate the association of lung ultrasound scores with the severity of hemodynamically significant patent ductus arteriosus (PDA) at time of diagnosis, as well as describe lung ultrasound changes pre and post-treatment with systemic steroid course.
Hypothesis:
- LUS scores would have a predictive ability to identify extreme preterm infants at risk of BPD with AUC>0.8.
- Higher LUS scores would correlate with higher severity of hemodynamically significant PDA.
- LUS scores are expected to be lower after the course of systemic steroids and with lower scores are expected to predict successful extubation following the course of systemic steroids.

Cohorts and Interventions
Group / Cohort |
Intervention / Treatment |
---|---|
RDS
Infant born less than 32 weeks gestation with diagnosis of respiratory distress syndrome.
Lung ultrasounds will be performed on day of life 7, 14, 21, 28 and at corrected gestational age of 36 weeks.
|
Lung ultrasound to be performed at scheduled intervals as described in individual cohorts.
|
PDA
In addition to being less than 32 weeks gestation, subject can qualify for study and receive a lung ultrasound scan at time of echo diagnosis of patent ductus arteriosus (PDA).
|
Lung ultrasound to be performed at scheduled intervals as described in individual cohorts.
|
Steroid
Aims are : A: To evaluate changes in LUS scores pre and post treatment with systemic steroid course. B: To evaluate the predictive ability of LUS for successful extubation following course of systemic steroids. Lung ultrasound scans will be done prior to initiation of post-natal steroid, day 1, day 3, day 7, day 10 of treatment and 1 week after steroid is discontinued. |
Lung ultrasound to be performed at scheduled intervals as described in individual cohorts.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Assess predictive ability of lung ultrasound scores in infants at risk of developing bronchopulmonary dysplasia (BPD)
Time Frame: The lung ultrasounds will be performed on day of life 7, 14, 21 and 28 and diagnosis of BPD would be per standard criteria.
|
The primary outcome is to assess accuracy measures including specificity, sensitivity and area under ROC of lung ultrasound cut offs for predicting BPD.
|
The lung ultrasounds will be performed on day of life 7, 14, 21 and 28 and diagnosis of BPD would be per standard criteria.
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Association between lung ultrasound scores and severity of patent ductus arteriosus.
Time Frame: The lung ultrasound would be performed around the time of echocardiographic diagnosis of patent ductus arteriosus and severity determined by standard criteria.
|
Secondary outcome is to assess correlation between lung ultrasound scores and severity of patent ductus arteriosus.
|
The lung ultrasound would be performed around the time of echocardiographic diagnosis of patent ductus arteriosus and severity determined by standard criteria.
|
Comparison of lung ultrasound scores pre and post systemic steroid course administration
Time Frame: The lung ultrasound would be performed prior to steroid administration, 24 hours, 72 hours, 7 days, 10 days and 17 days after the first dose of 10 day course of systemic steroid administration.
|
Comparison of lung ultrasound scores prior to and after course of systemic steroid administration would be analyzed using paired T-test or the signed Wilcoxon rank sum test.
|
The lung ultrasound would be performed prior to steroid administration, 24 hours, 72 hours, 7 days, 10 days and 17 days after the first dose of 10 day course of systemic steroid administration.
