Prediction of extubation readiness using lung ultrasound in preterm infants

We aimed to test the hypothesis that a lung ultrasound severity score (LUS) and assessment of left ventricular eccentricity index interventricular septum (LVEI) by focused heart can predict extubation success in mechanically ventilated infants. conducted prospective study on premature infants less than 34 weeks’ gestation. LUS was performed postnatal Days 3 7 an investigator who masked infants’ ventilator parameters. LVEI pulmonary artery pressure (PAP) were measured at Day 3. A receiver operator curve constructed assess ability success. Spearman correlation between PAP. total 104 studies 66 infants; them 39 had mild 65 moderate-severe disease. predicted with sensitivity specificity 91% 69%, respectively. Area under 0.83 (CI: 0.75–0.91). did not differ succeeded failed extubation. It correlated PAP during systole (r = .66). conclude predicts preterm whereas correlates high
