Hi Tim
B Braun have a similar product which is used in our Operating Room. I
have been aware of the difficulty in decontaminating the hub – the
anaesthetists say it is better as they know the drug is going straight
into the vein – as opposed to using the injection port which can be an
issue if the IV is a bit dodgy! Thanks for your references and
suggestions,
Jenny

Hi Rosie,
You are correct. The BD Venflon IV cannula has been widely used
throughout Europe and the UK (well it was when I was there many years
ago). Is it the Pro Safety or the standard ported cannula?
This style of ported cannula has been around since the early 1980’s, so
despite the recent addition of a safety aspect, it is still old
technology (in regards to the port aspect).
A ported cannula has significantly increased infection rates due to the
inability to correctly scrub the hub or decontaminate the injection
port, as well as port cap failure.
Here is an Australian publication from NT in 2013 that may help in
product purchase changes – Tay, S et al. Functional evaluation and
practice survey to guide purchasing of intravenous cannulae, BMC
Anesthesiology 2013, 13:49 http://www.biomedcentral.com/1471-2253/13/49
There has also been reports from the UK of the ports failing – H. Adler,
R. Cunningham, R. Parimkayala Valve failure in an injection port, Irish
Journal of Medical Science June 2011, Volume 180, Issue 2, p 615
http://link.springer.com/article/10.1007/s11845-010-0622-z
These ported styles of cannula were likely introduced due to the higher
number of UK physicians coming to work in WA (possibly due to clinician
preference only) and have high infection and poor compliance rates, due
to the difficult nature of port location. These are primarily placed in
OT only (as you describe) and are not used in the general wards areas as
far as I am aware.
Although this may be a ‘convenient option’ for clinicians, it is not in
the best interest of the patient, due to the higher risks associated
with these types of cannulae.

Considering the ongoing changes in technology and increased focus on
device and patient outcomes, these references are very old and dated. I
agree with you that this as a huge risk for contamination and a breach
of AT principles.
The BD Nexiva cannula would seem to be a far better alternative (for
patient and clinician), and still offering a safety option, various
access points and improved securement.

Hello
Recently I have been made aware of this practice following
implementation of Aseptic Technique Policy. It appears in our theatres
the Anaesthetists use the BD Venflon(tm) intravenous catheter with
integrated injection port and valve for medication and this stays in the
patient. I am told the caps are either being left open in Theatres for
quick access by Anaesthetists or they popp off very frequently. In
recovery nurses are observed continuing to use this to administer
medication. I see this as a huge risk for contamination and a breach of
AT principles.
The BD representative states that this type of catheter is not used in
other states of Australia but is common in UK and Europe. Is this
correct?
Have you come across this in your hospitals? If so have you ceased the
use or do you advocate using the side extension tubing which has a hub
that can be scrubbed?
