摘要

Objective

To investigate the association between lung ultrasound score (LUS) and left ventricular eccentricity index at end-systole (LVEI-s) and end-diastole (LVEI-d) in preterm infants with respiratory failure.

Study Design

This prospective pilot study included 38 ultrasounds on 20 premature infants with Transient Tachypnea of the Newborn (TTN) and Respiratory Distress Syndrome (RDS) requiring non-invasive ventilation at birth. LUS, LVEI-s, and LVEI-d were obtained daily for 72 h. Linear regression analysis was performed to determine correlation.

Results

LUS positively correlated with LVEI-s (r = 0.47, p = <0.01) and LVEI-d (r = 0.63, p = <0.01) during the 72-hour study period in the RDS group, but not the TTN group. Correlation increased over the first 24 h (LVEI-s: r = 0.69, p = <0.01; LVEI-d: r = 0.68, p = <0.01) in the RDS group.

Conclusion

As LUS increases, both LVEI-s and LVEI-d demonstrate measurable changes in infants with RDS. This association may enhance precision in diagnostic stratification and optimizing fluid management in neonatal lung disease.
