Tom Woodcock: The Revised Starling Principle and The Glycocalyx! #FOAMed, #FOAMcc

So today, I had the chance of having a private tutorial with Dr. Thomas Woodcock (@thomaswoodcock) about the glycocalyx and the revised Starling principles.  For anyone interested in fluid resuscitation, this is an area you have to delve into. The basic principles we all learned (which are still being taught) are basically the physiological equivalent of the stick man we all started drawing as toddlers: overly simplified and far from an accurate representation of reality.

Now my first disclaimer is that I have been a colloid supporter for many years. My physiological logic for that had been to minimize the crystalloid spillover into inflamed/septic areas, particularly the lungs and abdomen, when those are the septic sources. However, I was likely misled by my education and lack of knowledge about the endothelium.

So I stumbled upon the whole glycocalyx thing a couple years ago, and this prompted me to try more enteral fluids – the only way fluids normally ever enter the vasculature – but little else. Aware that it’s there, but unsure what to do about it.

Now a year and a half ago, Andre Denault, my closest thing to a mentor, casually dropped the line to me about albumin not working. “Don’t use it. It doesn’t act the way we think it does.”  But it was a brief chat, and I didn’t get to pick his brain about it.  Just a few weeks ago, I discuss with Jon Emile (Kenny), and he’s coming to the same conclusion.  Damn. I’m finding it a bit harder to hang on to my albumin use, which is beginning to look a bit dogmatic and religious.

Here is Jon-Emile’s take on it – a must-read.

Here is Tom Woodcock’s site and article – another must-read.

And here is my discussion (in two parts) with Tom (to skip the silence, skip forward to about 30 seconds into each – sorry my editing skills are limited!)

 

Bottom line?

Probably stick to isotonic crystalloids, and some hypertonics.

 

Love to hear some thoughts!

Cheers
