To examine the relationship between prenatal magnesium sulfate exposure and the risk for cerebral palsy(CP)or mental retardation(MR)among very low birth weight(VLBW;,1555g)children.Secondarily,to investigate the effect of prenatal magnesium sulfate exposure on VLBW infant mortality.A reduced risk for CP and possibly MR among VLBW children is associated with prenatal magnesium sulfate exposure.The reduced risk for childhood CP or MR does not appear to be due to selective mortality of magnesium sulfate- exposed infants. |
