Precautions
The following maternal blood concentrations cause symptoms of magnesium sulfate toxicity: loss of deep tendon reflexes (9.6-12 mg/dL), respiratory depression (12-18 mg/dL), and cardiac arrest (24-30 mg/dL). Moderately elevated serum magnesium levels are common during pregnancy and can be caused by many factors other than true magnesium deficiency.

What happens when magnesium levels are low?
Low levels of magnesium can result in the loss of competitive inhibition at the neuromuscular junction, allowing for increased acetylcholine release, resulting in neuromuscular irritability. Without competitive inhibition, the threshold of motor nerve excitation diminished, leading to enhanced myofiber contraction. Clinical symptoms of hypomagnesemia include, but are not limited to, muscle spasms, hyperreflexia, or ECG changes. Most notable changes seen on ECG include the widening of the P-R interval, widening of the QRS complex, and peaking of the T waves. [6]
What is hypermagnesemia?
Hypermagnesemia is a state of elevated magnesium levels with serum concentrations higher than 2 mmol/L. It rarely presents unless renal insufficiency is present or the patient is exposed to high levels of exogenous magnesium. Clinical signs of hypermagnesemia result in neuromuscular blockade or vasodilation—high levels of circulating magnesium lead to inhibition of calcium influx through the voltage-gated channels. Without calcium influx into the cell at the neuromuscular junction, no acetylcholine is released, leading to muscle contraction slowing. Clinical symptoms of hypermagnesemia include, but are not limited to, weakness, decreased respiratory drive, hyporeflexia, hypotension, or electrocardiogram (ECG) changes. The most notable ECG changes are P-R interval prolongation, an increase in the Q-T interval, or an increase in QRS duration leading to heart block.
How does magnesium affect the cellular membrane?
One role that magnesium plays is helping ion transport and maintain balance across the cellular membrane. Magnesium also acts as cofactors for enzymatic activation in multiple biochemical pathways such as glycolysis and the Krebs cycle. Intracellular magnesium is vital for neurochemical transmission and muscular contractions by working indirectly at the neuromuscular junction. More specifically, Mg2+ ions compete on voltage-gated calcium channels, affecting the distribution of calcium uptake and release. Magnesium also affects calcium metabolism by stimulation or suppression of Parathyroid Hormone (PTH).
Can magnesium sulfate be given to a patient with preeclampsia?
If any known hypersensitivity reaction to magnesium sulfate has occurred in the past, it should not be administered. If a patient is in a known heart block, magnesium sulfate should not be given as it can exacerbate the already slowed cardiac conduction. Many manufacturing labels recommend withholding magnesium sulfate infusions in patients with preeclampsia/eclampsia two hours before fetal delivery due to possible interaction with neuromuscular blocking agents given intraoperatively; however, the medication should not be stopped due to the possibility of precipitating seizure activity. [7]
Does magnesium sulfate cause hypotension?
In patients with neuromuscular disease, such as in myasthenia gravis, the neuromuscular function may worsen at lower concentrations of medication. If given rapidly or in high doses, patients may experience transient hypotension due to smooth muscle inhibition causing a vasodilatory effect that will resolve. If the patient is on a continuous magnesium sulfate infusion, serum levels must be accounted for as symptoms related to hypermagnesemia may become clinically evident. At supratherapeutic serum concentrations, absent reflexes, abnormal cardiac conduction, and muscle weakness may occur.
What is magnesium sulfate?
Magnesium is a naturally occurring mineral that is important for many systems in the body especially the muscles and nerves. Magnesium sulfate also increases water in the intestines.
What other drugs will affect magnesium sulfate?

What is the pH of sodium bicarbonate?
Sodium bicarbonate solution is slightly basic being the salt of a weak acid H2CO3 (CO2 + H2O) and a strong base NaOH, the pH of the solution being 8–9 depending on its concentration. Magnesium sulphate solution is slightly acidic the pH being 5.5 -6.5 (depending on its concentration) due to magnesium’s affinity for OH- ions. Therefore, when the solution of magnesium sulphate is added to the solution of sodium bicarbonate magnesium sulphate would first undergo hydrolysis forming magnesium hydroxide and sulphuric acid and the sulphuric acid thus formed would react with sodium bicarbonate forming sodium sulphate with the evolution of carbon dioxide. The chemical reactions involved may be represented as follows. MgSO4 + 2H2O = Mg (OH)2 + H2SO4. 2NaHCO3 + H2SO4 = Na2SO4 +2CO2 + 2H2O. Adding up the reactions MgSO4 + 2NaHCO3 = Na2SO4 + 2CO2 + Mg (OH)2. So when magnesium sulphate solution is added to a solution of sodium bicarbonate the products are sodium sulphate, carbon dioxide and magnesium hydroxide.
How many grams of MgSO4 is 24 grams?
5.As per the balanced equation 24 grams of Mg gives 120 grams of MgSO4.
What is the solubility limit of water?
The solubility limit is a ratio, a given amount of water can only hold so much salt or sugar. If that solution boils you remove some of the water, but leave all the salt/sugar behind. There's less water now, so some of the salt/sugar has to come out of solution and crystallize.
What happens when a substance is not soluble?
To do this, add sugar or salt to water and mix it. Keep adding more salt or sugar slowly unt. Crystallization is what happens when one substance is not soluble (or soluble enough) in one substance to remain dissolved.
How to make crystals from water?
Keep adding more salt or sugar slowly until a couple of the crystals don't dissolve any more. You just made a solution that is at it's solubility limit. From here you can cool it down and start seeing crystals form. That's because for most substances the solubility limit decreases with colder temperatures. If you heat it up you those crystals would dissolve, and you could actually keep adding more salt or sugar. But something changes if it starts boiling. The solubility limit is a ratio, a given amount of water can only hold so much salt or sugar. If that solution boils you remove some of the water, but leave all the salt/sugar behind. There's less water now, so some of the salt/sugar has to come out of solution and crystallize. Engineers use both the cool down method and the boiling method to make crystals industrially.

What is the role of magnesium in the body?
It is essential for the activity of many enzyme systems and plays an important role with regard to neurochemical transmission and muscular excitability. Magnesium sulfate reduces striated muscle contractions and blocks peripheral neuromuscular transmission by reducing acetylcholine release at the myoneural junction. Additionally, Magnesium inhibits Ca 2+ influx through dihydropyridine -sensitive, voltage-dependent channels. This accounts for much of its relaxant action on vascular smooth muscle.
How is magnesium excreted?
Magnesium is excreted solely by the kidney at a rate proportional to the serum concentration and glomerular filtration. Magnesium sulfate is excreted by the kidneys at a rate that varies from one patient to another but that is directly proportional to the serum concn and glomerular filtration. McEvoy, G.K. (ed.).
