• Before initiation and after completion of
loading dose
• Then q 15 mins x 4
• Every 30 mins x 2
• Then every hour
Comes packaged as 40 grams in 1000 ml
of Normal Saline. You will have to
calculate at what rate to set the pump for
the Alaris pump for both the loading dose
and the maintaince dose

every hour. If absent STOP MAG and notify
OB provider

output <25-30 ml/hour: STOP MAG and
notify OB provider

ordered - 18Magnesium Sulfate Class & ActionAlkaline earth metal sulfate

If given more than one dose requires an EKG be done on the woman to rule out cardiac issues.
