Md. Santi et al., MAGNESIUM-SULFATE TREATMENT OF PRETERM LABOR AS A CAUSE OF ABNORMAL NEONATAL BONE MINERALIZATION, Journal of pediatric orthopedics, 14(2), 1994, pp. 249-253
Twelve infants born to mothers who received i.v. magnesium sulfate for
>6 weeks for the cessation of preterm labor were evaluated radiograph
ically shortly after birth. All infants were born at >33 weeks gestati
onal age. All twelve infants demonstrated consistent and unique radiog
raphic abnormalities in the metaphyses of their long bones. The extent
of abnormality was at least partially related to the length of magnes
ium sulfate exposure, and appeared to completely resolve within the fi
rst few months of life.
