Your health service organisation will have a process that describes what your healthcare team should do to avoid too many attempts at inserting your PIVC. For example, if your clinician cannot locate your veins, the process outlines what steps they should follow. They might need to refer you to another clinician or use an ultrasound to help, or use other supportive therapies such as local anaesthetics to help keep you comfortable while your PIVC is inserted.
If they try to insert your PIVC and cannot, it can cause your treatment to be delayed. This is why it is important for your clinician to conduct a thorough assessment of the risk factors that might make inserting your PIVC difficult, and for you to say if you have had any issues with PIVCs in the past.
