I wouldn't know. Ahem. Cough. Is it warm in here?

I think most of us have been there and done that!

Take care,

The great thing about that type of "incident" is that the CA glue we use is
great at gluing cuts back together, in all but the very worst cuts.

It doesn't even have to slow you down!

Besides that, a plane with a little blood mixed in always seem to fly
better. That's why mine all fly fantastic! gg

Ah yes. Blood, sweat, and tears. I feel a song coming on....

Seriously, these days, they do glue you back together for some wounds and
surgeries.... I just hope it isn't model airplane glue they are using.

Probably a bit of quality control done to insure a line of accountability
having to do with raw material purity and repeatability, and testing to make
sure the product is pure, but not much more than that. Enough to change the
price of the product upwards several thousand percent.

Using it to glue a cut back together occasionally is something I won't lose
any sleep over, that is for sure.

The use of cyanoacrylate glues in medicine was considered fairly early
on. Eastman Kodak and Ethicon began studying whether the glues could
be used to hold human tissue together for surgery. In 1964 Eastman
submitted an application to use cyanoacrylate glues to seal wounds to
the United States Food and Drug Administration (FDA). Soon afterward
Dr. Coover's glue did find use in Vietnam--reportedly in 1966
cyanoacrylates were tested on-site by a specially trained surgical
team, with impressive results. According to an interview with Dr.
Coover by the Kingsport Times-News:

Coover said the compound demonstrated an excellent capacity to
stop bleeding, and during the Vietnam War, he developed disposal
cyanoacrylate sprays for use in the battle field.

"If somebody had a chest wound or open wound that was bleeding,
the biggest problem they had was stopping the bleeding so they could
get the patient back to the hospital. And the consequence was--many of
them bled to death. So the medics used the spray, stopped the
bleeding, and were able to get the wounded back to the base hospital.
And many, many lives were saved," Coover said.

"This was very powerful. That's something I'm very proud of--the
number of lives that were saved," he said.

Ironically, the Food & Drug Administration hadn't given approval
for the medical use of the compound at that point. But the military
used the substance, anyway (reference 1).

Although cyanoacrylate glues were useful on the battlefield, the FDA
was reluctant to approve them for civilian use. In part, this was due
to a tendency of the early compounds (made from
"methyl-2-cyanoacrylate") to irritate the skin as the glue reacted
with water and cured in the skin, releasing cyanoacetate and
formaldehyde. A compound called "butyl-2-cyanoacrylate" was developed
to reduce toxicity, but suffered from brittleness and cracking a few
days after application. Finally an improved cyanoacrylate glue was
developed for medical applications called "2-octyl-cyanoacrylate."
This compound causes less skin irritation and has improved flexibility
and strength--at least three times the strength of the butyl-based
compound (reference 2). As a result, in 1998 the FDA approved 2-octyl
cyanoacrylate for use in closing wounds and surgical incisions, and in
2001 approved it for use as a "barrier against common bacterial
microbes including certain staphylococci, pseudomonads, and
Escherichia coli" (reference 2). This latest incarnation was marketed
under the name Traumaseal as well as the more popular Dermabond.

Cyanoacrylate glues also find use in medicine for orthopedic surgery,
dental and oral medicine (marketed as Soothe-n-Seal), veterinary
medicine (Nexaband), and for home use as Band Aid brand Liquid
Bandage. It even has been explored as a potential treatment for
emphysema, where it can be used to seal off diseased lung passages
without the need for invasive surgery.

Is it safe to use ordinary household cyanoacrylate glue as a medical
glue? According to Reference 7, most cyanoacrylate glues not designed
specifically for medical use are formulated from
methyl-2-cyanoacrylate, since it produces the strongest bond. Not only
can such glues irritate the skin, during polymerization they can
generate significant heat, to the point of causing skin burns. I
gather this is a problem only if a large area of skin is affected. But
to err on the side of safety, you should tell your brother-in-law he
should only use medically-approved glue, not the ordinary kind. And
always be careful using it--I know families are supposed to stick
together, but there are limits.
