OBJECTIVE: To assess the relationship between umbilical cord blood magnesium concentration and level of delivery room resuscitation received by neonates.

RESULTS: There was no relationship between cord blood Mg and delivery room resuscitation (OR, 0.92 for each 1.0-mEq/L increase in Mg; 95% CI, 0.83-1.03). Maternal general anesthesia was associated with increased neonatal resuscitation (OR, 2.51; 95% CI, 1.72-3.68). Each 1-week increase in gestational age at birth was associated with decreased neonatal resuscitation (OR, 0.63; 95% CI, 0.60-0.66).

STUDY DESIGN: This was a secondary analysis of a controlled fetal neuroprotection trial that enrolled women at imminent risk for delivery between 24 and 31 weeks' gestation and randomly allocated them to receive either intravenous magnesium sulfate or placebo. The cohort included 1507 infants with data available on total cord blood Mg concentration and delivery room resuscitation. Multivariate logistic regression was used to estimate the association between cord blood Mg concentration and highest level of delivery room resuscitation, using the following hierarchy: none, oxygen only, bag-mask ventilation with oxygen, intubation, and chest compressions.
