Abstract

OBJECTIVE:

To estimate the efficacy of a rescue course of antenatal corticosteroids in twin pregnancies.

DESIGN:

Retrospective cohort study.

SETTING:

Tertiary-care centre.

POPULATION:

Twins born from 24 to <34 weeks of gestation in a single maternal and fetal medicine practice from 2006 to 2011.

METHODS:

We compared neonatal outcomes in 88 twins exposed to a single course of corticosteroids with outcomes in 42 twins exposed to two courses of corticosteroids: the initial course and a single rescue course. Analyses were adjusted to control for correlation between twins born to the same mother.

MAIN OUTCOME MEASURE:

Short-term neonatal respiratory morbidity.

RESULTS:

Rescue corticosteroids were associated with fewer days of mechanical ventilation (7.3 ± 3.3 versus 33.9 ± 25.3 days, P = 0.003), fewer days with a fraction of inspired oxygen of >21% (6.3 ± 4.3 versus 33.3 ± 25.8 days, P = 0.003), a lower incidence of mechanical ventilation >14 days or death while on mechanical ventilation (0 versus 12.5%, P = 0.016), and a lower incidence of retinopathy of prematurity (0 versus 12.5%, P = 0.016). The proportion of neonates with respiratory distress syndrome did not differ between the groups (adjusted odds ratio 1.28, 95% confidence interval 0.50-3.26). There were no differences found for birthweight, head circumference and length.

CONCLUSIONS:

In twins born before 34 weeks of gestation, exposure to rescue corticosteroids may be associated with improved neonatal outcomes. Further studies are warranted to assess the effect of rescue corticosteroids in twin pregnancies.
