The document discusses guidelines for using magnesium sulfate to reduce the risk of cerebral palsy in preterm infants. It describes protocols for magnesium sulfate administration before imminent preterm birth between 23-33 weeks gestation. Magnesium sulfate is thought to exert neuroprotective effects through vasodilation, anti-inflammatory actions, and modulation of NMDA receptors. Larger clinical trials and meta-analyses support the efficacy and safety of magnesium sulfate for reducing cerebral palsy.
