Yikes, here's the Wiki on propofol:
http://en.wikipedia.org/wiki/Propofol

Propofol is a short-acting intravenous sedative agent used for the induction of general anesthesia for adults and children, maintenance of general anesthesia, and sedation in medical contexts, such as intensive care unit (ICU) sedation for intubated, mechanically ventilated adults, and in procedures such as colonoscopy. It provides no analgesia.[1] Yet in some studies, when patients receive propofol compared to inhalation agents for anesthesia, postoperative pain is less after propofol.[2] Propofol is approved for use in more than 50 countries. It is also commonly used in veterinary medicine.
