I always had the problem that the swelling started too fast, before the infusion was finished, and therefore I had a lot of trouble with sealing the infusion site. Some nights were terrible.
So I was looking for a solution to get in the Glucose faster. Speeding up the drip-speed was not possible, so I've thought that rising the concentration of Glucose is the solution. Here in Germany it is not possible to buy more than 5% Glucose without prescription, so ready made 10%, 20% or 40% has not been available for me. But, amazingly, 50% is, without prescription. I decided to give it a try.
The first experiment saw 1 Liter 5% and 100 ml 50%, I thought that with already 1 Liter 5% in the following 100 ml 50% wouldn't be a problem. I was wrong, while infusion of 5% didn't hurt at all, the following 50% were really, really uncomfortable, weeks after the infusion I could still feel a knob where the injection was. I can definitely not recommend to do this, in fact, I warn against it.
For the second run I filled first the 100 ml-bottle 50% into one of the 500 ml 5%-bags (there is plenty of room in them) and left the second bag untouched, this equals to 1,1 liters of 9% Glucose. First I infused the untouched bag, then the "upgraded" one. After half an hour it was done, the infusion was much more better then the first one, but even here, the second bag felt a bit uncomfortable. However, sealing was now no problem, there was practically no migration and finally I've reached 61 cm (or 24"), see the attached pictures. This really felt good, but I couldn't left home for one complete day, there were no pants to fit.
However, once more: Never try pure 50% !
I'd love to see more photos if you took any more.
