I had a patient that was dropping her pressure on propofol, switched her to ativan and fentanyl drips, and it was just as bad. She was on 20 mcg dopamine and 250 mcg of neosynephrine, definitely was not hypovolemic. Would you try ativan alone, or fentanyl alone, or something else? I know ativan and fentanyl work synergistically to create sedation, do they do the same to blood pressure when they are combined?
