anesthesia
"I am a 72 year old woman.  I had propofol for a heart ablation.  They had a hard time trying to start my IV and when finally in it was very painful to even move my wrist but decided to leave it in as it was working and I didn't want them to dig around any more. In the operating room they put the oxygen mask on me and then said I would be going to sleep.  They said what they were putting in my IV might burn a little.  It was horrible!  It felt like they poured boiling water on my arm and it just kept getting more intense.  I tried to get away and screamed at them but they kept up till I passed out.

Horrible, experience.  Have had 6 major surgeries and never had this happen before."
