What indicates the need for admission of a patient on magnesium sulfate for preterm labor?

The indication for admission of a patient on magnesium sulfate for preterm labor primarily revolves around the need for careful monitoring of the patient’s response to therapy and potential side effects of magnesium sulfate, particularly concerning the neurological status and reflexes. Continuous absence of deep tendon reflexes serves as a critical sign that magnesium sulfate levels may be excessively high, leading to magnesium toxicity. This situation demands immediate medical attention and intervention, potentially meaning the patient needs to be admitted for closer surveillance, adjustments in medication, or further management.

In the context of magnesium sulfate therapy, monitoring deep tendon reflexes is vital because a diminished or absent reflex indicates nervous system depression due to elevated magnesium levels. This monitoring ensures that the administration of magnesium is both safe and effective in preventing preterm contractions while minimizing risks to the mother and fetus.
