I am interested if anyone knows of any ongoing studies related to using ports without a blood return and if INS is going to make any recommendations such as this.
The 2017 ONS standards states "If no other option exists after verification of VAD intactness, position, and patency and confirmation by imaging study of the lack of backflow, obtain a provider order to use a VAD when there is no blood return "(Polovich et al, 2014).
There is another published statement from an ONS author “Ongoing controversy persists whether or not to use a VAD when a blood return is not present. Although there can be no definitive recommendation made based on evidence, strong expert opinion consensus recommends that specific analysis is performed before any use under these circumstances”.
If a venogram fails to determine the cause of lack of blood return how should verification of use continue since catheter migration can occur at any time? This is perplexing me.
Also, if anyone has any policy links addressing this I would appreciate it.
