Table 3 Randomized clinical studies investigating the neuroprotective effect of magnesium administered before delivery to women at risk for preterm birth (a) and administerd to children born at term after perinatal asphyxia (b)

From: Magnesium treatment for neuroprotection in ischemic diseases of the brain

Author Study setup Treatment arms and comedication Individuals Results
A     
Schendel et al., 1996 [61] Observational Preterm administration for tocolysis. Dose variable, observational study 1097 births with very low birth-weight Reduced risk for cerebral palsy and mental retardation
Crowther et al., 2003 [64] Randomized Preterm administration of 16 mmol MgSO4 followed by 4 mmol/h for 24 hours to mother vs. placebo 1062 women in gest. week 30 or less with birth planned within 24 hours Lower rate of pediatric mortality and cerebral palsy in the treatment group
Marret et al., 2007 [63] Randomized Preterm administration of 16 mmol MgSO4 (4 g) single-dose over 30 minutes 573 women in gest. week 33 or less with birth planned within 24 hours Non-significant reduction of infant mortality and white matter injury
Magpie Trial Follow-Up Collaborative Group, 2007 [66] Randomized Preterm administration of 16 mmol MgSO4 followed by 4 mmol/h for 24 hours to mother vs. placebo 3283 children born before gest. week 37 Non-significant reduction of disability after 18 months
Rouse et al., 2008 [65] Randomized Preterm administration of 24 mmol MgSO4, followed by 8 mmol/h 2241 women in gest. week 24 – 32 with birth anticipated within 24 hours Significant reduction of cerebral palsy
B     
Levene et al., 1995 [68] open MgSO4 400 mg/kg vs. 250 mg/kg 15 full-term neonates with asphyxia 400 mg/kg: Serum level 3,6 mmol/l, profound hypotension and respiratory depression
250 mg/kg: Serum level 2.42 mmol/kg, no effect on herat rate, blood pressure and respiration
Groenendaal et al., 2002 [69] Randomized MgSO4 (250 mg/kg 30 min after birth and 125 mg/kg after 24 and 48 hours vs. placebo 22 full-term neonates with asphyxia No effect on pathological EEG patterns
Ichiba et al., 2002 [70] Randomized MgSO4 (3 × 250 mg/kg in 24-hour intervals) vs. placebo 34 full-term neonates with asphyxia Less pathological CT- and abnormal EEG-findings. Higher rate of oral feeding and good short-term outcome ( at 14 days of age) in magnesium-treated children
Gathwala et al., 2006 [71] Randomized MgSO4 (250 mg/kg 30 min after birth and 125 mg/kg after 24 and 48 hours vs. placebo 40 full-term neonates with asphyxia Safe use of magnesium. No change in heart-rate, respiratory rate of blood pressure
Bhat et al., 2009 [72] Randomized MgSO4 (3 × 250 mg/kg in 24-hour intervals) vs. placebo 40 full-term neonates with asphyxia Less neurological abnormalities and pathological CT findings
Gethwala et al., 2010 [73] Randomized MgSO4 (250 mg/kg 30 min after birth and 125 mg/kg after 24 and 48 hours vs. placebo 40 full-term neonates with asphyxia Less EEG- and CT abnormalities and better short-term outcome in magnesium-treated children
