Re: How high have you titrated levophed?
Is "through the roof" a valid response to this question?
We go as high as we have to with levo. We add vasopressin empirically at a rate of 0.04 units/min after we hit twenty mcgs on the levo. Other issues are addressed, of course---they're intubated, lined up, swanned (though less frequently than in the past), often end up on CVVHDF, and are the classic very sick ICU patient.
I have had massively septic patients on as high a rate as 200 (yes, two hundred--not a typo) mcgs/min and have had them live---and really live. Alive, extubated, kidneys working again. LOL---back to asking for another pillow and the remote for the TV. It's rather wonderful.

We almost never use neo except in immediately-post-surgical patients (anesthesiologists seem to love it) or patients who become hypotensive while receiving Interleukin 2 therapy (pressor of choice with those patients, according to our oncologists). We do levo first, add vaso, then epi if we need a third pressor. Rarely dopamine unless HR is also low---too arrythmogenic.
Sorry I don't have the time at the moment to read this whole thread so maybe I've just repeated what others have already said but I thought I'd toss this out as an "IME" post.
