Clinical Trial Summary

The goal of this observational study is to learn about the role of bedside lung ultrasound in infants born prematurely with breathing problems. The main question this study aims to answer is: Can bedside lung ultrasound performed in the first month of life predict the development of chronic lung disease in premature infants?

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: 1. LUS scores would have a predictive ability to identify extreme preterm infants at risk of BPD with AUC>0.8. 2. Higher LUS scores would correlate with higher severity of hemodynamically significant PDA. 3. 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.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Assess predictive ability of lung ultrasound scores in infants at risk of developing bronchopulmonary dysplasia (BPD)	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	Association between lung ultrasound scores and severity of patent ductus arteriosus.	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.
Secondary	Comparison of lung ultrasound scores pre and post systemic steroid course 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.
