I was discussing central line placement complications with medical students a few days ago. Some of them are illustrated with horrifying details in the NEJM."What should you do if you lose a guide wire during central line placement?", I asked.
"We could use a strong magnet to pull it out", one of the students suggested.
Well, not really.
You should call interventional radiology immediately and the radiologist will extract the wire under fluoroscopic guidance by using another wire to hook up and pull out the lost one.
A few examples of different approaches to extract lost guide wires are listed in the British Journal of Anaesthesia.
We have published free illustrated step-by-step procedure guides to central placement with and without ultrasound. The guides are available as web pages and Windows Mobile/Palm downloads.
