These data indicating persistent benefits of MgSO4 regardless of dose and support the use of low doses (e.g., 4 g loading dose ± 1 g/h maintenance dose for 12 h, 16 g maximum total dose) compared to high doses (e.g., 6 g loading dose + 2 g/h maintenance dose during 24 h, maximum total dose received: 54 g). When deciding on a birthing plan, it’s important to be aware of your options and to create a plan that fits your needs. Magnesium affects several pathways potentially involved in preterm brain injury. Although hydralazine is the most commonly administered agent, it was recently compared to intravenous labetalol or oral nifedipine in a metaanalysis of trials. The study was stopped prematurely in January 1997 due to significant mortality in the MgSO4 group (58, 59) and was widely discussed (60–63). doi:10.3171/jns.1996.85.1.0117, 21. Several studies have reported the importance of the timing of MgSO4 administration. மினுவாங்கொடை காவல் நிலைய சிற்றுண்டிச்சாலையின் ஊழியர் ஒருவருக்கு கொரோனா! doi:10.1515/jpm-2013-0151, 39. The aim of this review is to describe the proposed mechanisms of action of magnesium sulfate for fetal neuroprotection, different dosing regimens of the drug that have shown benefit, and to review recent pharmacokinetic studies of the drug to better inform clinicians regarding expected benefits and remaining research questions. Recurrent seizures can be treated with a bolus of 2 to 4 g of magnesium sulfate. Boyle CA, Yeargin-Allsopp M, Schendel DE, Holmgreen P, Oakley GP. Treatment with magnesium sulfate is 25 to 50 mg/kg per dose (with a maximum of 2 g/dose) given intravenously over 20 to 30 minutes in nonurgent situations; it may be bolused if a patient has polymorphic VT. Serum levels should be monitored, with some controversy regarding the utility of monitoring ionized levels.

Evaluation of long-lasting sensorimotor consequences following neonatal hypoxic-ischemic brain injury in rats: the neuroprotective role of MgSO4. doi:10.1515/jpm-2014-0176, 15. Particular interest for the maternal use of magnesium sulfate in the prevention of neurological deficits in infants born prematurely began with a report that only 7.1% of VLBW infants with later cerebral palsy were exposed to maternal magnesium sulfate versus 36% of a control group.213 In a subsequent study of approximately 1000 premature infants, those whose mothers received magnesium sulfate had a lower prevalence of cerebral palsy (0.9%) than those whose mothers did not receive this agent (7.7%).214 However, subsequent evidence regarding benefit for magnesium sulfate for prevention of cerebral palsy or associated brain lesions or both has not been consistently positive.215-231 Meta-analyses have shown that antenatal magnesium sulfate administered for neuroprotection in preterm infants is associated with a reduction of cerebral palsy at a corrected age of 18 to 24 months,232-234 but studies of longer-term outcomes have failed to show benefit.235,236. Obstet Gynecol (2009) 114:354–64. Nelson KB, Grether JK. HHS Side effects include reflex tachycardia, cerebral vasodilation, and potential cyanide toxicity. More data are needed on these issues. Owing to its biological properties, including its action as an N-methyl-d-aspartate receptor blocker and its anti-inflammatory effects, magnesium is a good candidate for neuroprotection.
