Postnatal Steroids Effects on Cardiac Function in Extremely Preterm

Left Ventricular Hypertrophy

Hypothesis/Study question

In infants born at less than 29 weeks of estimated gestational age, what are the effects of dexamethasone use on cardiac structure/performance and lung water content?

Study objectives

To measure effects before and after dexamethasone administration on cardiac structure/performance will be evaluated by using the M-mode technique (Devereux method (25-27) and lung water content will be specifically determined by the degree of water retention in premature lungs assessed by lung ultrasound at the pre specified time points.

Methodology / Study design

Single center, prospective observational cohort study planning to enroll eligible patients over a period of 12 months
