Abstract
Magnesium is an essential mineral with pivotal roles in various physiological processes, including enzyme function, neuromuscular regulation, and cardiovascular health. Magnesium's importance in critically ill pediatric patients is magnified due to its involvement in maintaining cellular homeostasis and potential therapeutic benefits. This review comprehensively analyzes magnesium's role in critical care pediatrics, focusing on its physiological mechanisms, clinical impact, and therapeutic strategies. Magnesium's functions in energy production, protein synthesis, and electrolyte balance underscore its significance in critical illness, where imbalances can lead to severe complications such as arrhythmias, neuromuscular disturbances, and respiratory issues. The review examines the clinical consequences of magnesium deficiency, including its impact on various body systems and the potential exacerbation of critical conditions. It also explores therapeutic strategies to optimize patient care, including supplementation practices, dosing considerations, and monitoring protocols. By summarizing recent research and clinical guidelines, this review aims to enhance understanding of magnesium's role in critical care and provide evidence-based recommendations for its management. The insights provided are intended to guide clinicians in integrating magnesium therapy into critical care practices, ultimately improving patient outcomes and advancing the management of critically ill pediatric patients.

Nelakuditi M, Kumar S, Shaikh SM, Parepalli A, Kumar MJ. A Narrative Review on Magnesium Sulfate as a Game Changer in Reducing ICU Stays in Organophosphate Poisoning Cases. Cureus 2024; 16:e65481. [PMID: 39188488 PMCID: PMC11345587 DOI: 10.7759/cureus.65481] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/15/2024] [Accepted: 07/26/2024] [Indexed: 08/28/2024] Open
Abstract
Organophosphate (OP) poisoning is a critical public health issue, particularly in agricultural regions where these compounds are extensively used as pesticides. The toxic effects of OP compounds arise from their inhibition of acetylcholinesterase, leading to an accumulation of acetylcholine and a subsequent cholinergic crisis, which can be fatal if not promptly treated. Traditional management of OP poisoning includes the administration of atropine and pralidoxime; however, these treatments often fall short of reducing the high morbidity and mortality associated with severe cases. Recent research has highlighted the potential of magnesium sulfate as an adjunctive treatment for OP poisoning. Magnesium sulfate exerts its beneficial effects through mechanisms such as calcium channel blockade and stabilization of neuromuscular junctions, which help mitigate the cholinergic hyperactivity induced by OP compounds. Clinical studies have shown that magnesium sulfate can significantly reduce the duration of intensive care unit (ICU) stays and improve overall patient outcomes. This narrative review aims to comprehensively analyze current insights into using magnesium sulfate to manage OP poisoning. It discusses the pathophysiology of OP poisoning, the pharmacological action of magnesium sulfate, and the clinical evidence supporting its use. Furthermore, the review will address the safety profile of magnesium sulfate and its potential role in current treatment guidelines. By synthesizing available evidence, this review seeks to establish magnesium sulfate as a game-changer in the management of OP poisoning, ultimately contributing to better clinical practices and patient outcomes.

Abstract
OBJECTIVES The study aims to investigate the relationship between hypomagnesemia, preclinical hypomagnesemia, and normomagnesemia as along with geriatric syndrome and comprehensive geriatric parameters(CGA). METHODS 217 patients who applied to the geriatric clinic between November 2022 and December 2023 were included in the study. All patients underwent CGA. Patients were categorized into three groups: Magnesium (Mg) level ≤ 1.5 mg/dL, Mg level 1.5-1.8 mg/dL, and Mg level > 1.8 mg/dL. These three groups were compared in terms of demographic characteristics, comorbidities, CGA parameters, and geriatric syndromes. Regression analyses was conducted for significant parameters, adjusting for confounders. RESULTS 74.9% of all participants were female, with an average age of 76.5 ± 6.6 years. The frequency of hypomagnesemia was 14.2%. Demographic characteristics and medication use, including proton pump inhibitors and diuretics, were similar in these three groups. While the FRIED frailty scale and the duration of the timed-up-and-go test were higher in the hypomagnesemia group, the Basic Activities Daily of Living (ADLs) and the Tinetti-POMA(performance-oriented mobility assessment) scores were lower in the hypomagnesemia group. When normomagnesemia was accepted as the reference category, FRIED frailty scale, Basic ADLs, and POMA score were more significant in the hypomagnesemia group (p = 0.025, p = 0.013 and p = 0.011,respectively), but there was no significance in the preclinical hypomagnesemia group regardless of the covariates. CONCLUSION Hypomagnesemia, particularly serum Mg levels below 1.5 mg/dL, may be associated with frailty, basic ADLs, gait, and balance tests. In geriatric practice, patients with hypomagnesemia should be evaluated in terms of the risk of the mentioned disorders.

Abstract
Background Asthma is the common chronic inflammatory disease affecting children. It is usually associated with airway hyper-responsiveness. Globally, the prevalence of asthma among pediatrics population varies from 10% to 30%. Its symptoms range from chronic cough to life-threatening bronchospasm. At emergency department, all patients with acute severe asthma should initially receive oxygen, nebulized β2-agonists, nebulized anticholinergic agent, and corticosteroids. Though bronchodilators act within minutes, corticosteroids may require hours. Magnesium sulphate (MgSO4) was first considered for treating asthma about 60 years ago. Several case reports were published on its usefulness in decreasing admission and endotracheal intubation. So far, evidence is conflicting to fully employ MgSO4 for asthma management in children under five. Objective This systematic review was aimed to evaluate the effectiveness and safety of MgSO4 in the treatment of severe acute asthmatic attacks in children. Methods A systematic and comprehensive search of literature was performed to identify controlled clinical trials conducted on IV and nebulized MgSO4 in pediatric patients with acute asthma. Results Data generated from three randomized clinical trials were included in the final analysis. In this analysis, intravenous MgSO4 did not improve respiratory function (RR=1.09, 95%CI: 0.81-1.45) and not safer than conventional treatment (RR=0.38, 95%CI: 0.08-1.67). Similarly, use of nebulized MgSO4 showed no significant effect on respiratory function (RR=1.05, 95%CI: 0.68-1.64) and more tolerable (RR=0.31, 95%CI: 0.14-0.68). Conclusion Intravenous MgSO4 may not be superior to conventional treatment in moderate to severe acute asthma among children and neither have significant adverse effects. Similarly, nebulized MgSO4 showed no significant effect on respiratory function in moderate to severe acute asthma in children under five but it seems a safer alternative.

Effect of magnesium sulfate in oxidized lipid bilayers properties by using molecular dynamics. Biochem Biophys Rep 2021; 26:100998.

Abstract
Magnesium sulfate (MgSO4) has been used as a protector agent for many diseases related to oxidative stress. The effect of MgSO4 on the oxidized lipid bilayer has not yet been studied using molecular dynamics calculations. In this work, the effects of oxidation were evaluated by using a POPC membrane model at different concentrations of its aldehyde (-CHO) and hydroperoxide (-OOH) derivatives with and without MgSO4. Several quantitative and qualitative properties were evaluated, such as membrane thickness, area per lipid, area compressibility modulus, snapshots after simulation finish, density distributions, time evolutions of oxidized group positions, and radial distributions of oxidized group concerning Mg. Results indicate that in the absence of MgSO4 the mobility of oxidized groups, particularly –CHO, toward the surface interface is high. At a low oxidation level of the bilayer there is an increase in the compressibility modulus as compared to the unoxidized bilayer. MgSO4, at a low oxidation level, tends to lessen the oxidation effects by lowering the dispersion in the distribution of oxidized species toward the membrane surface and the water region. However, MgSO4 does not change the trends of decreasing membrane thickness and area compressibility modulus and increasing area per lipid upon oxidation. In this regard, MgSO4 diminishes the electrostatic long-distance attractive interactions between the oxidized groups and the charged headgroups of the interface, owing to the Mg+2 and SO4-2 screening effects and an electrostatic stabilization of the headgroups, preventing the pore formation, which is well-known to occur in oxidized membranes. MgSO4 in vitro restores oxidized membranes but its molecular mechanism is unclear. MD simulations of oxidized lipid bilayers were performed with and without of MgSO4. A restriction in the mobility of oxidized groups is produced by MgSO4. Mg+2 and SO4= produce screening effects on the oxidized membranes. MgSO4 produce a diminution of electrostatic long-distance attractive interactions.

Abstract
Monitoring and measuring magnesium (Mg) values are essential to prevent the development of numerous complications in perioperative medicine and critically ill patients. Although previous studies suggest that measuring free ionized magnesium (iMg) is more useful for estimating Mg status, clinicians currently rely on measurement of total serum magnesium to determine if supplemental magnesium is needed. In this review, we analyzed the recent literature to decide whether it is better to measure ionized serum Mg or total serum Mg when assessing magnesium status, whether iMg predicts clinical outcome, and what are the difficulties in measuring serum iMg levels in intensive care patients and perioperative medicine.

Abstract
OBJECTIVES In this study, changes in lactate clearance following magnesium supplementation were evaluated in critically ill patients with severe sepsis. METHODS Fifty-eight patients with severe sepsis were randomly assigned to receive either magnesium (n = 30) or placebo (n = 28). Patients in the magnesium group received intravenous magnesium sulfate to maintain serum magnesium level around 3 mg/dL for 3 days. The placebo group received the same volume of normal saline. Change in lactate clearance was considered primary outcome of the study. RESULTS Mean increase in the lactate clearance in the magnesium group was significantly higher than the placebo group on day 2 (27.53% vs. 23.79% respectively, p < 0.001) and day 3 (49.83% vs. 37.02% respectively, p < 0.001). Time to lactate clearance was also significantly shorter in the magnesium group than the placebo group (47.28 ± 20.59 vs. 61.20 ± 24.31 h respectively, p = 0.03). Sepsis-related mortality was not significantly different but median length of ICU stay was significantly shorter in the magnesium group than the placebo group (8 vs. 15 days respectively, p < 0.01). CONCLUSIONS Magnesium supplementation increased lactate clearance in critically ill patients with severe sepsis. Optimizing serum magnesium level near the upper limit of the normal range may improve severe sepsis outcomes.

Eliminating Risk of Intubation in Very Preterm Infants with Noninvasive Cardiorespiratory Support in the Delivery Room and Neonatal Intensive Care Unit. BIOMED RESEARCH INTERNATIONAL 2019; 2019:5984305. [PMID: 30733962 PMCID: PMC6348842 DOI: 10.1155/2019/5984305] [Citation(s) in RCA: 13] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 06/19/2018] [Revised: 11/09/2018] [Accepted: 12/20/2018] [Indexed: 11/18/2022]
Abstract
Introduction Avoiding intubation and promoting noninvasive modes of ventilator support including continuous positive airway pressure (CPAP) in preterm infants minimizes lung injury and optimizes neonatal outcomes. Discharge home on oxygen is an expensive morbidity in very preterm infants (VPI) with lung disease. In 2007 a standardized bundle was introduced for VPI admitted to the neonatal care unit (NICU) which included delayed cord clamping (DCC) at birth and noninvasive ventilation as first-line cardiorespiratory support in the delivery room (DR), followed by bubble CPAP upon NICU admission. Objective Our goal was to evaluate the risk of (1) intubation and (2) discharge home on oxygen after adopting this standardized DR bundle in VPI born at a regional perinatal center and treated in the NICU over a ten-year period (2008-2017). Materials and Methods We compared maternal and neonatal demographics, respiratory care processes and outcomes, as well as neonatal mortality and morbidity in VPI (< 33 weeks gestation) and extremely low birth weight (ELBW, < 1000 g) subgroup for three consecutive epochs: 2008-2010, 2011-2013, and 2014-2017. Results Of 640 consecutive inborn VPI, 55% were < 1500 g at birth and 23% were ELBW. Constant through all three epochs, DCC occurred in 83% of VPI at birth. There was progressive increase in maternal magnesium during the three epochs and decrease in maternal antibiotics during the last epoch. Over the three epochs, VPI had less risk of DR intubation (23% versus 15% versus 5%), NICU intubation (39% versus 31% versus 18%), and invasive ventilation (37% versus 30% versus 17%), as did ELBW infants. Decrease in postnatal steroid use, antibiotic exposure, and increase in early colostrum exposure occurred over the three epochs both in VPI and in ELBW infants. There was a sustained decrease in surfactant use in the second and third epochs. There was no significant change in mortality or any morbidity in VPI; however, there was a significant decrease in pneumothorax (17% versus 0%) and increase in survival without major morbidity (15% versus 41%) in ELBW infants between 2008-2010 and 2014-2017. Benchmarked risk-adjusted rate for oxygen at discharge in a subgroup of inborn VPI (401-1500 g or 22-31 weeks of gestation) is 2.5% (2013-2017) in our NICU compared with > 8% in all California NICUs and > 10% in all California regional NICUs (2014-2016). Conclusion Noninvasive strategies in DR and NICU minimize risk of intubation in VPI without adversely affecting other neonatal or respiratory outcomes. Risk-adjusted rates for discharge home on oxygen remained significantly lower for inborn VPI compared with rates at regional NICUs in California. Reducing intubation risk in ELBW infants may confer an advantage for survival without major morbidity. Prenatal magnesium may reduce intubation risk in ELBW infants.

Abstract
Magnesium is well known for its diverse actions within the human body. From a neurological standpoint, magnesium plays an essential role in nerve transmission and neuromuscular conduction. It also functions in a protective role against excessive excitation that can lead to neuronal cell death (excitotoxicity), and has been implicated in multiple neurological disorders. Due to these important functions within the nervous system, magnesium is a mineral of intense interest for the potential prevention and treatment of neurological disorders. Current literature is reviewed for migraine, chronic pain, epilepsy, Alzheimer’s, Parkinson’s, and stroke, as well as the commonly comorbid conditions of anxiety and depression. Previous reviews and meta-analyses are used to set the scene for magnesium research across neurological conditions, while current research is reviewed in greater detail to update the literature and demonstrate the progress (or lack thereof) in the field. There is strong data to suggest a role for magnesium in migraine and depression, and emerging data to suggest a protective effect of magnesium for chronic pain, anxiety, and stroke. More research is needed on magnesium as an adjunct treatment in epilepsy, and to further clarify its role in Alzheimer’s and Parkinson’s. Overall, the mechanistic attributes of magnesium in neurological diseases connote the macromineral as a potential target for neurological disease prevention and treatment.

Abstract
BACKGROUND Magnesium (Mg) is essential for life and plays a crucial role in several biochemical and physiological processes in the human body. Hypomagnesemia is common in all hospitalized patients, especially in critically ill patients with coexisting electrolyte abnormalities. Hypomagnesemia may cause severe and potential fatal complications if not timely diagnosed and properly treated, and associate with increased mortality. MAIN BODY Mg deficiency in critically ill patients is mainly caused by gastrointestinal and/or renal disorders and may lead to secondary hypokalemia and hypocalcemia, and severe neuromuscular and cardiovascular clinical manifestations. Because of the physical distribution of Mg, there are no readily or easy methods to assess Mg status. However, serum Mg and the Mg tolerance test are most widely used. There are limited studies to guide intermittent therapy of Mg deficiency in critically ill patients, but some empirical guidelines exist. Further clinical trials and critical evaluation of empiric Mg replacement strategies is needed. CONCLUSION Patients at risk of Mg deficiency, with typical biochemical findings or clinical symptoms of hypomagnesemia, should be considered for treatment even with serum Mg within the normal range.

Abstract
Magnesium is the fourth most abundant cation in the body. It has several functions in the human body including its role as a cofactor for more than 300 enzymatic reactions. Several studies have shown that hypomagnesemia is a common electrolyte derangement in clinical setting especially in patients admitted to intensive care unit where it has been found to be associated with increase mortality and hospital stay. Hypomagnesemia can be caused by a wide range of inherited and acquired diseases. It can also be a side effect of several medications. Many studies have reported that reduced levels of magnesium are associated with a wide range of chronic diseases. Magnesium can play important therapeutic and preventive role in several conditions such as diabetes, osteoporosis, bronchial asthma, preeclampsia, migraine, and cardiovascular diseases. This review is aimed at comprehensively collating the current available published evidence and clinical correlates of magnesium disorders.
