Oral glucose is allowed and recommended for several reasons. Yes, it is more rapidly absorbed & entered through the bucosal/mucosa route, it is easy to administer, cheap, and very little danger to it.
Now, if the patient has < LOC; caution should be taken; making sure that the patient is in a recovery position and monitor the airway and suction PRN. Choking and aspiration can still occur, since the preventive reflexes are absent.
There is another route that glucose syrup could be administered, but doubtful most would prefer to give it...
I can't remember this being even somewhat controversial, and I've even seen ALS give it via the oral route (I had to look up buccally).
It's clearly not as fast as some D50, the miracle drug, but it definitely works.
So what you're saying is it can be absorbed through the gum directly into the bloodstream? Furthermore, you're saying this is faster than being absorbed through the GI system if swallowed?
This is what I've been taught since emt-b class years ago. The reason I bring this up is...I can only do bls at my volly fire station and I gave a little oral glucose to a pt with decreased BGL. The AIC from EMS who is a CCEMT-P like me, walks in and tells me to stop giving the glucose buccally because "the glucose molecules are too big to be absorbed through the tissue." I respect (or at least I did) this mans knowledge and was wondering if this was a controversial/debatable issue or if there are any new points of view on the subject.
