It has been 7 years since this study came out, and many since. Here we are still using saline like it’s benign. Part of the problem is that clinicians get set in their ways and just don’t read. Sorry if that offends anyone, but it’s true. Some say, “this has always worked and I haven’t seen a problem with it” so they keep doing what they’re doing. Our job is to cause no harm. I’m trying my best to minimize that but after all, we are all human. Being lazy is no excuse, though. Hyperchloremia causes harm.
This article from 2012 shows a study that was performed on 12 healthy volunteers. It was a randomized, double blind, cross over study. I bet they were either college students or medical students; the mean age was 22. This was not disclosed in the article, of course. The participants received either 2L of 0.9% NaCl or plasma-lyte over an hour on separate occasions 7 to 10 days apart. If you still don’t know what Plasma-lyte is, you must be new here. They did some bloodwork as well as MRI’s. They must have had some good funding here.
A hat tip to the authors.
