Magnesium sulfate

My current job says we have to have LR as a main line.   They use anesthesia tubing, connected directly to IV site hanging by gravity and clamped off.   Then hang another LR infusing on pump at 75 ml/hr and magnesium on second chamber infusing at 50 ml/hr.   Per management, this is awhonn standard to have a mainline of LR.   I've never worked anywhere else that we had to have a bag of LR connected to infuse by gravity but clamped off.   Is this really an awhonn standard?   I've always just considered my LR infusing on a pump to be my primary line.   Is mainline and primary line two different things?   How do you hang magnesium at your hospital?

The LR on the pump IS the main line. So you have 2 bags of LR hanging, one of which is not actually infusing? What is its purpose? Management is correct that you should have a main line/primary line of LR, but that's what the LR at 75 is.

One bag of LR on a pump. One bag of MgSO4 on a pump. Done. 

And then, more likely than not, one bag of Pit on a pump as well.

Is it an emergency backup in case you need to bolus very quickly?

The primary line on the pump would serve that purpose.

We always ran it the way Klone said, LR on one pump, MGS04 on the other. And if needed, pitocin on a 3rd pump as well.
