The condition of the vein has a lot to do with it, but there are also
many factors in the engineering of catheters that are involved. The
length of the bevel, the angle of the bevel, the way the catheter
meets the stylet, the shoulder of the catheter tip, etc, etc. are all
part of the intricate design that goes into making catheters and all
of these factors affect the pop feeling. Lynn

It was a big surprise to me when I started actually watching veins in
real time on the US screen as I poked them with needles. I was amazed
at how much they compress under the needle before being punctured. They
are much tougher than I imagined. Many times the vein will completely
collapse under the needle, and continue to deflect downward, until
finally the needle penetrates the wall. And this is with the small
sharp needle of the micro introducer, with no catheter on it to hang up
on the vein wall. This effect is probably much less with the low
insertion angle of the PIV insertion. I suspect the experience of the
"pop" is probably more a factor of the attention and awareness of the
nurse and the condition of the vein than differences from catheter to
catheter.

Catheters that allow one to feel the pop when the vein is entered may
be increasing the chance of vein damage. Think about what that pop
feeling represents - the vein wall resisting the stylet/catheter
entry causing the nurse to apply more force and possibly more trauma.
No pop means that the sharp stylet is slicing through the vein wall
with less resistance. While some may be dependent on the pop feeling,
I think the sharper ones are better for the patient. Lynn

It is extremely important for an IV specialist or whoever writes
the IV policies at your institution to compare the catheters
(previous vs. new) to see what the physical differences are prior to
throwing it out to the nurses to use on patients. Our last change
did not go well. The stylet exposed at the tip of the catheter was
a bit longer than the previous one and it was sharper, so nurses did
not feel the pop as it went into the vessel. Plus, it was more
flexible. So, we ended up with 2 specific insertion problems:
1) nurses went right through the vein because they couldn't feel the
pop, or 2) they had problems threading the catheter because of the
longer stylet--the catheter tip wasn't yet in the vein. And they
didn't like the more flexible catheter--too much bend during
insertion although we don't know what specific problems this caused.
It was difficult to convince our value analysis folks that just
because something was a few cents cheaper on the front end didn't
mean it was less expensive overall. Patient satisfaction
and inservicing for nurses all take its toll overall.

I have seen this catheter, and wondered about it. I would love to
hear any feedback from any users. Elvie, I would also like to hear
your nurses' specific complaints. I have found that a lot of nurses
complain about a new IV catheter until they get used to it. Perhaps
it is just a question of adapting to a difference in feel. Please
share any information you get.

Hello everyone,
We are trialing a new peripheral IV catheter called "secure IV", no
blood out after catheter insertion, the idea is great but our nurses
just don't like it, I don't know if it is design or technique.Does
anyone out there using it? Can you share us your insights???
thanks,
