Magnesium Sulphate in Perinatal Asphyxia

Magnesium sulphate has a neuroprotective potential as has been shown by many studied in pregnant ladies with eclampsia where it helped neonates also and in mothers with preterm labour where the incidence of cerebral palsy was less. We designed a randomised controlled trial on 40 neonates with severe perinatal asphyxia to see whether it helps in the short term outcome of these neonates.

Inclusion criteria

• Babies eligible for the study were:

• Term or post term
• Less than 6 hours of age and had
• severe perinatal asphyxia as manifested by any three of the following criteria.

• History of fetal distress (late deceleration, Loss of beat to beat variability, fetal bradycardia, meconium stained amniotic fluid)
• Need for immediate neonatal ventilation with bag and mask or through endotracheal intubation for 2 minutes or more after delivery
• A 5-minute Apgar score of < 6
• Base deficit 15 mEq/L in cord blood or admission arterial or cord blood pH 4.Moderate to severe encephalopathy

Exclusion criteria

• Patients with severe IUGR
• Any condition unrelated to asphyxia
• Maternal prenatal magnesium administration
• Metabolic disorder
• Chromosomal anomalies; and
• Congenital malformations were excluded from the study
