Primary Uses Of Magnesium In Obstetrics
- Magnesium sulfate has three main obstetric uses: seizure prevention in severe preeclampsia, fetal neuroprotection, and historically for preterm labor but not first-line for tocolysis.
- Use should be protocolized and standardized across the unit to reduce risk and variation.
One IV Is Usually Enough
- Do not require two IV lines routinely; run Pitocin and magnesium through the same IV and plug Pitocin into the port closest to the insertion site.
- Use a second IV only when medications like insulin are incompatible with magnesium or oxytocin.
Labeling, Double-Checks, And Bag Prep
- Label magnesium bags and lines and require a 2-RN check when initiating or changing bags or doses.
- Use pharmacy-prepared mixtures and separate bolus and maintenance bags (eg 20 g in 500 mL) to reduce dosing errors.
