pediatric hypermagnesemia

We aimed to investigate clinical and laboratory characteristics of acute alcohol intoxication (AAI) in adolescents who presented to the pediatric emergency department (ED) at a tertiary referral center from 2006 to 2019. All consecutive adolescents with AAI (n = 335) and their sex- and age-matched control subjects (n = 335) with undetectable ethanol levels were included in this case-matched study. Mean serum ethanol level was 156.4 ± 58.4 (range: 50.8-341.2) mg/dL in the acute alcohol intoxication (AAI) group...

BACKGROUND: Tubular dysfunction can cause electrolyte disturbances with potentially serious consequences. We studied the epidemiology and outcomes of electrolyte disturbances and tubular dysfunction among critically ill children and evaluated their relationships with acute kidney injury (AKI). METHODS: We conducted a prospective cohort study recruiting children aged 1 month to ≤ 18 years old admitted to the pediatric intensive care unit (PICU) from 6/2020 to 6/2021...

BACKGROUND: Ritodrine and magnesium sulfate are administered to prevent preterm labor. Magnesium sulfate is also administered to prevent preeclampsia. These drugs have been reported to increase potassium levels in pregnant women and neonates. The aim of this study was to investigate the relationship between potassium levels in preterm infants and antenatal treatment. METHODS: This prospective cohort study was conducted at Saiseikai Suita Hospital. Preterm infants born at <35 weeks' gestation between October 2012 and September 2014 were recruited and divided into four groups based on the antenatal treatment their mothers received...

Maternal use of magnesium sulfate has been associated with neonatal hypocalcemia and bone changes. We report the case of a preterm male infant who presented hypercalcemia before developing hypocalcemia after maternal magnesium sulfate therapy. Magnesium sulfate was used for premature rupture of membranes for 32 days, and the patient was delivered at 33 weeks gestation. The cord blood showed ionized calcium 1.54 mmol/L. His serum calcium and magnesium were 11.4 mg/dL and 3.5 mg/dL after birth and fell to 6.6 mg/dL and 2...

BACKGROUND: One of the possible adverse outcomes of magnesium sulfate (MgSO4) administration for preterm fetal neuroprotection is hypermagnesemia in the newborn. The objectives of this study were to evaluate the association between antenatal MgSO4 administration for neuroprotection and neonatal serum magnesium levels in the first days of life. METHODS: A single-center retrospective case-control study was conducted on preterm neonates born in our institution between January 2017 and December 2019...

OBJECTIVE: The effect of serum magnesium on the prognosis of children with sepsis in the pediatric intensive care unit (PICU) is unclear. This study was designed to assess the risk of inpatient mortality for children with sepsis in the PICU based on serum magnesium levels at admission. METHODS: We collected patients' clinical information from the Pediatric Intensive Care database and then performed locally weighted scatterplot smoothing (LOWESS) analysis, Kaplan-Meier analysis, and multivariate logistic regression to determine the relationship between admission serum magnesium and inpatient mortality in children with sepsis...

BACKGROUND: The prevalence of magnesium imbalance in critically ill children is very high. However, its significance in the development of acute kidney injury (AKI) and mortality remains unknown. METHODS: In this retrospective observational study from 2010 to 2018, the pediatric-specific intensive care database was analyzed. We included critically ill children aged > 3 months and those without chronic kidney disease. Patients were diagnosed with AKI, according to the Kidney Disease Improving Global Outcomes (KDIGO) study...

Pediatric patients may require magnesium replacement to treat life-threatening emergencies such as torsades de pointe or asthma exacerbations, as well as for the general replacement of magnesium in patients with hypomagnesemia. Clinicians must be aware of recommendations for magnesium administration as the route, dose, timing of administration, and formulation of magnesium can differ for each indication. It is imperative for clinicians to ensure that magnesium is appropriately administered to effectively treat the presenting indication and avoid adverse effects...

OBJECTIVE: Antenatal magnesium sulfate (MgSO4) is found to have various adverse effects in newborn, but the effect on preterm gut is still unclear. This study aimed to evaluate the effects of antenatal MgSO4 on preterm gut function by assessing the clinical outcomes and mesenteric blood flow. METHODS: This was a prospective cohort study on all preterm very low birth weight (VLBW) neonates born at a tertiary care center in South India from November 2016 to August 2017...

BACKGROUND: Hypermagnesemia can be a fatal condition and should be diagnosed early on. Most reports of hypermagnesemia have been of adults with impaired renal function. We describe the case of a pediatric patient without renal dysfunction who developed severe hypermagnesemia. CASE PRESENTATION: A healthy 20-month-old Asian girl presented to our emergency department with episodes of vomiting and a reduced level of consciousness. The neurological examination showed a symmetric decrease in muscle tone, and the deep tendon reflexes were decreased...

OBJECTIVES: Hypermagnesemia has been reported in preterm neonates treated with commercial pediatric triple-chamber bag (3CB) parenteral nutrition (PN). This postmarketing study was requested by the European Medicines Agency to assess the safety of a 3CB PN product in full-term neonates and children up to 24 months of age. METHODS: This prospective, multicenter, observational study enrolled hospitalized, full-term, newborn infants and children up to 24 months of age receiving >70% of nutrition as PN and requiring ≥50% of nutrition as PN for ≥5 days...

In this report, we present a pediatric case of severe symptomatic hypermagnesemia resulting from the use of magnesium oxide as a laxative in a child undergoing continuous cyclic peritoneal dialysis for end-stage renal disease. The patient showed abnormal electrocardiography (ECG) findings, such as tall T waves, a widened QRS complex, and irregular conduction, which were initially misdiagnosed as hyperkalemia; later, the correct diagnosis of hypermagnesemia was obtained. Emergent hemodialysis successfully returned the serum magnesium concentration to normal without complications...

Magnesium (Mg), an essential element, plays important roles in many physiological functions. Mg deficiency is associated with insulin resistance, cardiovascular disease, and disorders of the nervous system. The aim of this study was to determine reference values for serum Mg concentration in pediatrics. Serum Mg level was measured by flame atomic absorption spectrophotometry in 306 subjects (141 boys and 165 girls), aged 3-19 years, selected from among participants of the Tehran Lipid and Glucose Study. The International Federation of Clinical Chemistry guidelines (IFCC) and the robust method were used for determining reference values for sample sizes greater or less than 120 subjects respectively...

A high blood magnesium level is a rare but life-threatening event. This case report describes an accidental overdose of magnesium that occurred in an 18-month-old girl during a routine operation. The effects of high magnesium levels and its treatment are explained in detail.

We report a case of fatal hypermagnesemia resulting from the unsupervised use of high doses of magnesium oxide administered as part of a regimen of megavitamin and megamineral therapy to a child with mental retardation, spastic quadriplegia, and seizures. The treatment regimen was given at the recommendation of a dietician working as a private nutritional consultant without the involvement or notification of the child's pediatrician. Hypermagnesemia is an uncommon but serious side effect of the use of magnesium containing compounds...

OBJECTIVE: Our aim was to analyze the incidence of metabolic disturbances in critically ill children and to evaluate their correlation with severity of illness, complications, mortality and length of hospital stay. PATIENTS AND METHODS: We retrospectively studied 360 children who were admitted into a Pediatric Intensive Care Unit (PICU) between January 1995 and May 1996. We analyzed age, sex, initial diagnosis, complications, length of hospital stay and initial and final concentrations of serum glucose, calcium, phosphorus, magnesium and alkaline phosphatase...

A unique chemical intoxication by Dead Sea water and its resultant physiological effects of combined severe hypercalcemia and hypermagnesemia are described. Of 48 adult patients, 16 had at least one severe clinical manifestation of either disturbed sensorium or a syndrome similar to adult respiratory distress syndrome. The patients had tachyarrhythmias (11 of 38, 29%), conduction disturbance (nine of 37, 24%), and a normal QTc interval in the presence of severe hypercalcemia. Combined respiratory and metabolic acidosis and concomitant extreme hypercalcemia and hypermagnesemia, reaching serum levels up to 28...

Ca and Mg are biologically important minerals that are involved in maintaining the stability of membranes, muscle contractions, and enzyme activity in nearly all cells. Derangements of Ca and Mg homeostasis can precipitate serious and life-threatening problems in the critically ill patients. We examined serum ionized Ca and Mg levels in pediatric patients consecutively admitted to a pediatric ICU. Abnormal Mg and ionized Ca levels on admission were found in 43.3% and 17% of the patients, respectively. Hypocalcemia and hyper-magnesemia were both associated with poor outcome as measured by either survival or length of ICU stay...
