We recently had a potential error where a patient was recieiving mag (20gm/500mL) for pre-eclampsia who was also receiving maintenance fluids (LR) at the same time. The provider instructed nurse to turn of LR as the patient had a high urine output. Nurse was under the impression that magnesium must be infused concurrently with fluids to minimize irritation/infiltration. Our order sets/guidelines do not state this.
Have other institutions encountered this? It doesn't appear to be in any guidelines...is it just a best practice? I have not heard of this practice before.
