Predictors of Early Extubation after Patent Ductus Arteriosus Ligation among Infants Born Extremely Preterm Dependent on Mechanical Ventilation

We conducted a retrospective study of 166 ventilator-dependent neonates born extremely preterm in whom patent ductus arteriosus was surgically ligated and evaluated the association of preoperative characteristics and time-to-successful postoperative extubation. Larger patent ductus arteriosus diameter ([>2.5  mm], adjusted hazard ratio 0.51, 95% CI 0.36-0.72) and left-ventricular dilatation (z score ≥2, adjusted hazard ratio 0.61, 95% CI 0.42-0.87) were associated with earlier extubation.
