I unfortunately am not an OB RN, but keeping BP down will actually prevent pulmonary edema. Fluid overload can def do that, but I don't know how much IV / mag they're getting. I'd be more concerned with that.

Procardia, when used with magnesium sulfate infusion, can cause a neuromuscular blockade (paralysis). I have heard it explained simply, that you don't use procardia when the patient is on magsulfate because the procardia is a calcium channel blocker, and what is the antidote to magsulfate toxicity? Yep, calcium gluconate.

P.S. I work on an OB unit and that's how the docs explained it to us. Hope it makes a little sense!

the only time we do procardia + mag is when we are weaning the pt off mag for the same reason as above poster mentioned.

It doesn't sound like the patient in question had BP issues.
