Abstract

OBJECTIVE
To determine whether magnesium sulfate exposure is associated with a reduced risk of perinatal complications in extremely low birth weight infants (ELBWIs).
METHODS
Total 351 inborn extremely low birth weight infants admitted between January 2000 and December 2008 to Samsung Medical Center were divided into the prenatal MgSO4-exposed group (n=76), and control group (n=275), and were retrospectively analyzed. Multiple demographic, clinical characteristics and neonatal complications were compared.
RESULTS
Prenatally MgSO4-exposed ELBWIs had significantly higher gestational age, birth weight, and incidence of small for gestational age. In neonatal complications, retinopathy of premature (ROP) treated with laser was less common in MgSO4-exposed group. There were no differences between two groups in the incidence of respiratory distress syndrome (RDS), bronchopulmonary dysplasia (BPD), patent ductus arteriosus (PDA), PDA ligation, intraventricular hemorrhage (IVH), periventricular leukomalacia (PVL), necrotizing enterocolitis (NEC), and mortality.
CONCLUSION
Perinatal exposure to magnesium sulfate was associated with decreased incidence of ROP treated with laser.
