Abstract

Objective This study aimed to diagnose transient tachypnea of newborn (TTN) and differentiate it from respiratory distress syndrome (RDS) using lung ultrasound. Background TTN is a very common cause of neonatal respiratory distress and must be accurately differentiated from other causes of respiratory distress. Participants and methods A prospective observational cohort study was carried out on 120 newborns at the Neonatal Intensive Care Unit, Menoufia University Hospital, admitted with respiratory distress and subjected to an assessment of full history, clinical examination, arterial blood gas, chest radiography, and lung ultrasound. Results On lung ultrasound, TTN was found in 77.5% of cases (93) and RDS was found in 22.5% of cases (27). Lung consolidation presents only in RDS (100%) and not in any case of TTN. Double lung point presents only in TTN (80%) and not in RDS; thus, it showed a sensitivity of 80% and a specificity of 100% in diagnosing TTN (P < 0.001). Conclusion Lung ultrasonography can accurately diagnose TTN and differentiate between TTN and RDS as lung consolidation presents only in RDS and double lung point presents only in TTN.
