Lung ultrasound imaging can effectively monitor and guide treatment with pulmonary surfactant for preterm infants of pulmonary consolidation: a prospective observational cohort study

In preterm newborns, NRDS and TTN can be effectively managed using LUS-guided PS therapy based on consolidation monitoring. While TTN can be treated with a fixed-dose regimen, NRDS has a dose-response relationship that supports customized dosage. The frequency and timing of surfactant administration in preterm newborns are determined by LUS-detected lung consolidation, which also acts as a decision-making indicator for PS therapy.
