One of my co-workers was asked to de-access and re-access a port-a-cath for the sole purpose of placing a biopatch. We are uncomfortable with this. We have no experience placing biopatches with ports. We are concerned that with a close fit between the port and the needle,a biopatch could lead to infiltration or extravasation. Is this a valid consideration? What is the technique for placing a biopatch when accessing a port?
