I just found this thoracentesis video from the Loyola University Chicago on Yahoo Video. The video complements well our thoracentesis step-by-step procedure guide. It was added to Yahoo Video a month ago and has been viewed only 68 times.
There are also links to many other free medical videos from the Loyola University.
