You are absolutely right to have been concerned about starting this drip. I was trained in a unit where NO pressors are run through a peripheral line... and one look at a nasty infiltrate will explain why (see examples
here). However since I moved to the USA I see it happening more and more.... it makes me very uncomfortable. IMO Q1 assessments of the site is the absolute minimum I would check. I usually check Q15 minutes for any pressors that run through a peripheral line (also potassium, vanco, gent or any other harsh meds).
