I certainly commend your courage in voicing your concerns here. However, brace yourself for some heavy-duty backlash. You are certainly going against the grain and your comments, however well meant, will not be well received. Because you know, they're professional after all.
As for versed, I see you did your homework. I only wish many more patients would before consenting to that. That drug is viewed as the holy grail in many hospitals, mostly because it's a legal way to circumvent consent. A patient is a little reluctant, skittish, or simply doesn't want to play ball, they will offer a "calmant" to help you relax. In goes a shot of vitamin 'V' as it is called and bablamo instant compliance ensue. And, as an added bonus, the patient won't be able to remember a thing. Wonderful thing, versed.
You have my support (for what it's worth) and I wish you good luck.
