CTB is sometimes applied to skin before applying tape or other adhesive bandages in other circumstances having nothing to do with DM management. It protects the skin from allergy, they say. An example is spraying it on a broken limb before putting the cast on it, to minimize itching in subsequent days.
Moreover it's a light adhesive somewhat like what you find on a Smith&Nephew iv prep wipe. It's not a glue. It has only a little "stickiness" to it. Apparently, CTB is common in military settings as an item for keeping a dressing still. I never heard of a diabetic using it. The idea seems sound -- to use an alcohol prep, then a little CTB, and let it dry for a minute, then insert your infusion set there.
Anybody tried it? Do you know something better? Is it worth a try?
I don't see why it wouldn't help if you think skin allergy to tape is an issue.
Note: it must be "compound" and say so or it will not stick.
