I already passed my first attempt with 2 quart water + 40 ml Glycerine 85% (dosage according to German PflegeWiki, as seen here: http://tinyurl.com/3xnvdb4), but I have to say, I am disappointed, because I could not feel any difference to normal saline water.
The effect according to PflegeWiki should have been "mucous membrane irritation". Should I have felt something, or is it only about a very mild irritation which can not be felt at that small dosage?
Is the dosage of 20 ml glycerine each quart too conservative?
In what dosages is glycerin used else (for example for a punishment enema)?
