I work at a small rural hospital where we do mag very infrequently. I am wondering can you run mag and pit through the same IV? I seem to remember from when I worked at a large teaching hospital that we did that all the time. The mag would be piggybacked onto the mainline and the pit would be run directly in on the other y-site ext. I took care of a pt the other day who had 2 IV's in the same arm, one to run mag and the other pit, because the nurse who started her mag and induction insisted that mag and pit are not compatable. I could not find anywhere in a policy, drug book, or text book, where it said one way or the other. Let me know if anyone knows the answer. Thanks.
