Which treatment is indicated for hypotension associated with magnesium sulfate administration?

Magnesium sulfate is commonly used in obstetric clinical practice for various indications, including the management of preeclampsia and eclampsia. One of the side effects of magnesium sulfate is hypotension, which can occur due to its vasodilatory effects.

In the scenario where hypotension arises from magnesium sulfate administration, calcium gluconate is indicated as it serves to mitigate the effects of magnesium on the cardiovascular system. Magnesium can interfere with calcium’s role in vascular tone and contractility; therefore, administering calcium gluconate can help to counteract the hypotensive effects by providing an essential ion necessary for muscle contraction, including that of the heart.

Calcium gluconate acts as a direct antagonist to magnesium’s effects on the heart and blood vessels, improving overall cardiovascular stability. In emergency settings, where rapid intervention is crucial, this approach can be particularly effective in managing magnesium-induced hypotension.

Conversely, while normal saline can help expand intravascular volume and might be considered in scenarios of general hypotension, it does not specifically counteract the effects of magnesium as calcium gluconate does. Magnesium sulfate and atropine are not appropriate in this context, as magnesium sulfate would exacerbate the hypotension, while atropine primarily acts on heart
