Table 3 Factors associated with weaning from mechanical ventilation after a course of dexamethasone.

From: Efficacy of late postnatal dexamethasone on weaning from invasive mechanical ventilation in extreme premature infants

Factor Odds ratio (95% CI)
IPPV and FiO2 ≥ 0.50 at start of PND* 0.255 (0.074–0.875)
HFOV and FiO2 < 0.50 at start of PND* 0.153 (0.020–1.145)
HFOV and FiO2 ≥ 0.50 at start of PND* 0.140 (0.038–0.512)
  1. By multivariable stepwise binary logistic regression analysis. Other variables evaluated in the model included gestational age, age at start of PND, race, gender, maternal preeclampsia, chorioamnionitis, small for gestational age, multiple pregnancy, Apgar score < 5 at 5 min, severe respiratory distress syndrome, on mechanical ventilation during first day after birth, history of patent ductus arteriosus and sepsis.
  2. CI confidence interval, PND post-natal dexamethasone, HFOV high-frequency oscillatory ventilation, IPPV intermittent positive pressure ventilation
