Incomplete Antenatal Steroid Therapy Can Enhance Outcomes in
Preterm Infants with Emergency Conditions
OBJECTIVE: We aimed to investigate the role of incomplete of antenatal steroid therapy by comparing
with no and complete steroid exposure on mortality and morbidity in preterm infants.
STUDY DESIGN: This is a prospective, an observational study which includes preterm infants of 32
weeks of gestation and/or ≤1500 grams who were referred to Izmir Dr. Behcet Uz Children’s Hospital
NICU during the one year period. Infants were divided into three groups according to the administration
of antenatal steroid as those who received incomplete-dose antenatal steroid, complete dose steroid
therapy and those with no steroid exposure. Intubation at the delivery room, surfactant requirement, the
inotropic requirement in the first 72 hours and morbidities associated with prematurity were determined
as the primary results. Mortality and bronchopulmonary dysplasia at discharge and stage ≥2 retinopathy
were analyzed as secondary outcomes.
RESULTS: We found that 54 infants were born with an incomplete dose, 55 infants with complete dose
and 38 infants with no steroid therapy. Surfactant requirement, inotropic requirement, and hemodynamically
significant patent ductus arteriosus were lower in the steroid exposure group leading to a statistical
difference (p <0.05). Also, it was found that mortality and Bronchopulmonary dysplasia was lower in
the incomplete and complete dose steroid groups, leading to a statistical difference (p <0.05).
CONCLUSION: We speculate that even incomplete dose steroid may reduce mortality by reducing respiratory
distress syndrome.
