No it's a "silver impregnated central venous catheters". There's a
difference.
REPLY:
There is a semantic differnce only. Whether impregnated or coated, the
bottom line is there is silver associated with the catheter with the goal of
reducing catheter associated infections.

Why do you make me waste my time with shit you should have read and
understood in the first place?
"Use of catheters with the AgION antimicrobial system lead to a marked
reduction in catheter-associated infections of the bloodstream."
bloodstream=systemic and don't forget the the catheters are in the
heart which imo is not a topical application.

lol... read your own post. Wearing a HAZMAT suit all day long may reduce
systemic infections too. But not by any mechanism worth discussing here.
Any reduction of catheter associated infections stands to reduce the risk of
systemic infections. I was working on the assumption that you had that
basic understanding. Antimicrobial coated catheters can make the same claim
Pete. But that doesn't mean the antibiotic works systemically - it doesn't
and nor does the silver. It's a strictly local effect on the catheter
which, yes, may secondarily lead to a reduction of systemic infections ...
just like any coated catheter.

The Lifecath Expert is the most recent addition to Vygon's range of
antimicrobial enhanced central venous catheters. The AgIONŽ
antimicrobial delivery system ensures the regulated release of silver
ions. Over a period of one year, silver ions are released slowly from
the catheter's inner and outer surfaces, ensuring long term
protection. Expert catheters have proven effective against many
microbes, including gram-negative and gram-positive bacteria and fungi.

More comments on the local effects of preventing colonization of the
catheter.
