| Abstract [eng] |
Neonatal lung aeration is a critical process during the transition to extrauterine life, influenced by gestational age and mode of delivery. This study investigates early lung aeration patterns in healthy term and late preterm neonates born vaginally and via cesarean section (CS) using electrical impedance tomography (EIT), a non-invasive, real-time imaging technique. The results indicate that term neonates born vaginally exhibit superior pulmonary aeration compared to those delivered via CS, with fewer non-ventilated lung areas, particularly in gravity-dependent regions. Late preterm neonates demonstrate delayed aeration, with a higher proportion of poorly ventilated lung areas and initial aeration occurring predominantly in central rather than peripheral lung regions. Additionally, late preterm neonates show greater aeration heterogeneity and reduced lung inflation efficiency. These findings emphasize the importance of gestational maturity over delivery mode in early pulmonary adaptation and highlight EIT as a valuable tool for neonatal respiratory assessment. |
