Tricks of the Trade: A-Line Kits for Vascular Access

Ever struggle with vascular access?

Ever tried a 20G A-Line kit?

Even if you have,  once a flash is obtained it is common to not be able to thread the wire. If you pull the needle out of the catheter, it is rigid and difficult to replace in the catheter and rarely results in salvaging the attempt. In this video, I show you that by cutting the white cap off the back of the a-line kit, it will liberate the guide wire allowing the proceduralist to use it as a backup if the first attempt at placing the catheter fails. I have found,  many times when a flash is obtained but the wire doesn’t pass, the attempt can be salvaged with this technique. Enjoy…
