I am 5'4", 130lb, and I had a colonoscopy with Versed 3mg. and Fentanyl 100 mg. I endured pain the entire procedure and passed out when it was completed. My memory of it was not erased. The first thing I said was that it was horribly painful. I felt trapped. It was physical and mental torture. I told my spouse that I would rather be dead, and I meant it. I endured a painful nightmare that continues to disturb my sleep, and has caused aftermath episodes of painful gastric spasms. My doctor has apologized for these effects. He admits that I "did not have very much sedation", but denies that I experienced pain. His "procedure report" states that the patient tolerated the procedure well." I was not out; the sedative dulled only my ability to scream or to pull away from the nurse's hold on me. I hope I can get my blood pressure records. I am sending my experience to my state's health facility licensing and compliance division. No one should endure this.
