Does anyone use double lumen midlines for their patients? How are the outcomes using these lines? Thanks.
A few months ago, I went through all published evidence for midlines. This data is included in evidence tables in my online CE course on Midline Catheters. There are no published studies on dual lumen midlines at all. So there are no evidence based outcomes that could be generalized to other facilities or populations.

The facility that I work at is considering a dual lumen midline and the only question we had before we move forward is if there is any information on if you can infuse incompatible medications through the dual lumen considering it is not located in a central vessel. Would this be ok to do? If not we don't feel like a dual lumen would benefit us. Thank you in advance.

There is no evidence to provide the answer to your question.. Given the vast difference in volume of blood flow at the midline tip location and the SVC, IMHO I would say no to infusion of incompatibile medications through a dual lumen midline. A midline was never intended to totally replace a CVAD.
we tried double lumen. In theory, a D/L midline is a great solution. Then you get that argument about incompatible solutions . It's 2 seperate lines. The tip exits in the axilla. Why do nurses believe that two incombatible solutions exiting at the same time, immediately entering into a fast moving blood stream, somehow mix IN that blood and explode?. If that was the case, shouldnt we also look at two seperate peripherals in the same arm and the distance between them, to be sure the the meds don't mix at some point and cause a reaction?...and if so, what is that distance. Please will the nurse that came up with THAT theory enter this conversation and explain how that happens?
