Propensity score matching was used to ensure comparability between the groups, with a 1:1 match ratio based on gestational age and birth weight.ResultsA total of 66 infants were included in the study. Those who received early low-dose hydrocortisone demonstrated a significantly lower risk of Grade II+ BPD incidence (p = 0.024). Additionally, early administration of low-dose hydrocortisone was associated with a shorter duration of non-invasive ventilation days (p = 0.038). Multiple logistic regression analysis confirmed that hydrocortisone treatment was independently associated with a reduced risk of Grade II + BPD incidence (OR: 0.287, 95% CI: 0.084–0.980).ConclusionsThese findings suggest that early administration of low-dose hydrocortisone is associated with a reduced risk of Grade II+ BPD in extremely preterm infants born before 26 weeks of gestation.
