Decision base for re-siting peripheral intravenous cannulae

Thinking about the decision base for re-siting a peripheral intravenous cannula. Should it be based on time or clinical indications?

Insertion of peripheral intravenous cannulae (PIVC) is the most common vascular access procedure performed in hospitals [1]. Limm and colleagues have highlighted the prevalence of the “just in case” PIVC in Australia with Goddard and Thomas revealing a similar occurrence in the UK [2-5].

While we may have an unknown rationale for the insertion of PIVC, we also have an issue with the dwell time of PIVC. If we can’t resist inserting PIVCs, we also can’t resist taking a functioning PIVC out only to re-insert another. Considering the time, vessel health (reduced peripheral vein options) operator success and potential infection this is a clinical procedure that one really wants performed on as few occasions where possible.

Much debate surrounds the optimum dwell time of the PIVC. Over the past 50 years this has ranged from clinical indication to 24hrs to 96hrs. Clinical indication for removal includes pain, erythema/redness, induration, infiltration/extravasation, or an abnormal phlebitis score. If the device is not required for intravenous therapy it should be removed.

Questions for your hospitals vascular access team/ interest groups/ policy authors.

  • Is removing a functioning cannula without a clinical indication at 72hrs or 96hrs doing a disservice to your patient population?
  • Is leaving it until clinical indication to risk potential bacteraemia wise?
  • What evidence is this based on?
  • What is your departmental/hospital policy on PIVC removal?
  • Is there any high level evidence for this?

Discussion and debate over PIVC removal indications

At the 2013 Association for Vascular Access Scientific Meeting the Australian Vascular Access Research & Teaching (AVATaR) group presented a variety of vascular access studies. The Director of AVATaR Prof Claire Rickard delivered a keynote speech based in part on her recent Lancet publication “Routine versus clinically indicated replacement of PIVC” [5]

The FOAMed community now has the opportunity to add to this discussion and debate with Peter Carr (PhD student and advocate for vascular access teams) and Prof Claire Rickard both active on twitter…
