Abstract

Background: Lung ultrasound is a useful bedside tool in assessing different respiratory conditions of neonate. It is an emerging method in guiding clinicians to predict the need for surfactant administration in RDS neonates.

Methods: This study included 75 neonates less than 34 weeks requiring any form of respiratory support. Lung ultrasound score (LUS) was done initially at birth followed at 6-12 hours of life. Surfactant administration was based on clinical assessment.

Results: The LUS at birth (mean (SD): 8.5±2.93) and LUS at 6-12 hours of life (mean (SD): 6.2±3.06) showed a significant association with the requirement of surfactant administration and re-administration. Wilcoxon Sign rank test showed a significant decrease in the LUS score at 6-12 hours from LUS at birth. Also, the study shows that requirement of CPAP had positive correlation with LUS at birth and LUS at 6-12 hours.

Conclusions: The study shows significant association of LUS at birth and requirement of surfactant administration. Also, there is correlation between LUS at birth and LUS at 6-12 hours helping in predicting need for repeat dose of surfactant.
