Watch that fentanyl, Linda. Prior to gall bladder surgery about 2 years ago, I was given versad & fentanyl. I was to be given propofol (hello, Michael Jackson) for the anesthetic. Before the procedure or the propofol could begin I got very nauseous & was sweating profusely. I was wheeled back to my room post haste. Later that day, the surgery was performed using only morphine. I talked with the anesthesiologist later and was told they thought I was having a heart attack (they called in a cardiologist as I do have a heart condition). I will not let them touch me with that stuff again. So be careful with fentanyl!! - polly
