Hi Annelee. Hope you’re doing well and liking your new job. It’s 10:30 pm here and for me, that’s the middle of the night so rather than be friendly and “chat”, I’m going to get straight to the point – it’s business… So our hospital protocol essentially regurgitates ACOG, but it doesn’t specify that it is for use only with preeclamptic/eclampic patients. Would you use it for someone with chronic HTN also, barring known renal disease or other cause of the HTN? Thanks! Love, Aunt Crunchy
