MONTERROSA-CASTRO, Álvaro; ROMERO-PEREZ, Ivette  y  CARABALLO-OLAVE, Elida. Sulfato de magnesio y protección neuronal prenatal. Rev. chil. obstet. ginecol. [online]. 2013, vol.78, n.3, pp.201-208. ISSN 0717-7526.  http://dx.doi.org/10.4067/S0717-75262013000300006.

Background: Prematurity is a leading risk factor for development of cerebral palsy (CP). The use of Magnesium sulphate (MgSO4) has been proposed as a strategy to reduce the risk of cerebral palsy in preterm infants less than 34 weeks of gestation. Aims: To assess the best available evidence in order to validate the use of MgSO4 for prenatal neuroprotection in pregnant women at risk of imminent preterm delivery. Methods: we searched the PubMed, ScienceDirect, EBSCOhost, Scielo and OvidSP databases for clinical and epidemiological studies, systematic reviews, consensus and meta-analysis about the use of Magnesium sulphate to prevent cerebral palsy. Thematic review was conducted of articles that met the selection criteria. Results: Experiments in animal models showed properties of MgSO4 for neuroprotection. Observational studies indicated the possible association between fetal exposures to MgS04 and reduced neurological morbidity in PP. Five clinical trials between 2002 and 2008 showed no conclusive data individually. In 2009, three meta-analysis showed significant reduction of cerebral palsy in MgSO4 exposed preterm infants. Conclusion: There is evidence to recommend the use of MgSO4 for prenatal neuroprotection before 34 weeks of pregnancy and imminent risk of preterm birth. It is unclear the optimal dose of MgSO4; is recommended until delivery or by 12-24 hours.
