Needless access valve extensions

Is there evidence to suggest that use of an extension line access valve can decrease mechanical phlebitis potential, rather than use of a standalone access valve?

Great question Matt… however, an evidenced based answer is unlikely!

Working almost everyday on the materials published on IVTEAM I have the opportunity to review many infusion and vascular access publications. Even the publications that specifically look at peripheral IV catheter dislodgement are difficult to apply to all global IV clinical situations. The different type of vascular access device, method of securement and type of use (e.g. push injection, intermittent infusion or continuous infusion) are just some of the variables that may influence outcomes.

However, from my experience I can say that a short extension and needleless device appears to reduce the side to side ‘pendulum’ effect that is often seen with peripheral IV catheters as they are used. Of course, additional benefits include an ability to clean the access port and clamp under positive pressure.

To summarise, short extensions with needleless connectors appear to reduce movement of the vascular access device underneath the dressing, allow an aseptic technique to be followed and ensure the device can be ‘locked’ to prevent occlusion.

Hope this helps… best wishes
