Managing Difficult IV Cannulation

11m of CPD
‘Difficult intravenous access’ (DIVA), or ‘difficult peripheral intravenous cannulation’ (DPIVC), describes a situation wherein a practitioner is having difficulty gaining peripheral vascular access, often because the patient’s veins can not easily be seen or felt. It is generally defined as two or more failed cannulations, and/or needing to use advanced or rescue techniques to gain peripheral vascular access.

What is this article about?

Intravenous cannulation in prehospital settings enables the delivery of medicine, intravenous fluids, anaesthesia and other interventions prior to patient transportation. However, cannulation may be difficult and is associated with a high risk of complications. If the cannulation fails, this may further delay treatment and transport, potentially resulting in adverse patient outcomes.

Sometimes I find it really hard to make time for my learning, but I was blown away by how easy it is with the Ausmed app. I can fit it in during breaks or on the bus to work.
