So, recently I cared for a patient just over 31 weeks gestation with a hx of PTL admitted for PPROM. She was given our standard PPROM antibiotic protocol, steroids for baby's lungs, and magnesium sulfate for 24 hours for neuroprotection for the baby. I cared for her when she started going into labor, just a day or two after her initial magnesium infusion had been completed. Once her cervix started dilating and she was indeed in active labor, the OB ordered magnesium to be started again. I'm a little confused as to why we had to Mag this patient more than once. While some nurses on my unit confirmed that this was standard protocol, others were just as surprised as I was.
What is the magnesium policy on your units? If you have a patient in early enough preterm labor, do you mag her during labor (strictly for neuroprotection for baby, when hypertension is NOT an issue), regardless of whether she has already completed a previous magnesium infusion?
