That is so cool. When I worked in a clinic, I watched the doc drain fluid from a guy sitting up on the examining table. It wasn't the guy's first time. I assumed at the time the fluid was coming from his lung, but thinking back on it I don't really know where it was coming from. The basic procedure was the same as described here -- and I can't think why iodine shot back in there wouldn't have been a good idea. At least there was the Betadine scrub :)
