Propofol
"I'm age 52, it was my first colonoscopy and I was nervous. There is a slight stinging sensation at the IV site when they first start the med (not bad at all). The anesthesiologist said "good night" and I was OUT. I didn't hear or know anything until I opened my eyes in recovery and asked if we'd started yet. Within 20 minutes I was dressed and seated in a recliner reviewing my results with my doctor. A wonderful drug that quickly exits the system. Highly recommended."
