There really wasn’t much to learn. The needles usually stay where they are once in the hole until you pull them out (both pre and post treatment), and so it gives you time to work with your free hand while you tape or untape. To pull the needles out after treatment, I attach a scissor clamp at the end of each needle tube, so I can pull the needle out with the hand on my fistula arm, while I hold a gauze ready with the other hand. It’s not hard to do.
