Studies in digestion

I beautifully procrastinated on my biostats homework yesterday by learning about the Rule of 20. This is the mnemonic for all the many many thingies* to check on patients in critical care. My favorite by far is nutrition, because it is so important and yet easy to overlook. It requires thinking of the digestive tract as a true ecosystem all of its own. Vet school was the first place I had come across this notion, in such a way that it made sense** and it recasts the world when you start thinking of your intestines as something not unlike Pike Place Market. Fewer fish flying through the air, y'know, but otherwise, just like. It's not just the easily angered proletarian masses of bacteria, either. There's the constantly sloughing, constantly regrowing cells that balance the tract and absorb nutrients and respond to the environment. If they don't get fed, they are subject to atrophy, microscopic ennui robbing them of purpose.

So feeding the patients is important and feeding the patients in a normal way, i.e. the food goes into their stomach, then moves on to their intestines in due course. The odd nasogastric tube or surgically placed stomach tube takes nothing away from this process, but parenteral nutrition (enteral being the normal way), in which we inject a nice amino acid slurry through the IV catheter, misses the point of keeping ALL the patient's systems healthy. It is sometimes necessary, but it means that the instant that patient can hold down anything--usually the most pureed chicken-flavored baby food that money can buy--someone gets to start feeding him globs of it on a tongue depressor.

But today is back to biostats. I am indulging in a good breakfast, a la the importance of digestion, inspired by my conversation with myself:
--"I want french toast."
--"We always have french toast."
--"What spices can I use that I haven't put in french toast before?"
--"Um...we've used cinnamon, nutmeg, allspice, ginger, thyme, basil, pepper, cloves, and rosemary..."
--"Oo, I found rose extract!"
--"..."
--"Surely that would work?"
--"To the internets!"

And I found a lovely rose-cardamom french toast recipe here.
