Why are patients on magnesium sulfate for pre-e on a clear liquid diet/NPO even after delivery?

I thought it was because mag relaxes the muscles which puts patients at risk for vomiting/aspirating, but someone told me it was because pre-e patients are at risk for seizures which puts them at risk for vomiting/aspirating. Maybe it's both reasons? Thanks!

This may be hospital dependent because our PP moms on mag are allowed to eat a regular diet as tolerated. They are on a fluid restriction though due to the risk of fluid overload.

My best guess as to why some docs keep them NPO/Clear Liquids only is probably risk of aspiration from vomiting/decreased LOC.

When a patient is on Mg during labor, at what point AFTER the baby is born will they typically d/c the mag? There is the key. Is the NPO status for the safety of the fetus, or the mother?

Mag is stopped for the birth. Mag is restarted after the birth and run for 24 hours after the birth. Most my postpartum mag patients are allowed ice. Some are allowed clears. And a few are allowed food as tolerated. I have always thought it was to minimize vomiting. Mag and lack of sleep makes them feel crappy enough.
