In the most recent episode of Grey's Anatomy, we were treated to this horrifying plotpoint:
A woman is having abdominal surgery. While Dr. Bailey is digging through the woman's intestines, THE WOMAN WAKES UP.
The woman is frozen; she can't move, she can't speak. Meanwhile, Dr. Bailey does the #1 thing you're not supposed to do when you're operating on a woman and she wakes up: She freaks out.
If I ever need surgery for anything, here's what I want. I want my finger taped to a button attached to the side of the surgery table. If I feel myself start to wake up, I can press that button and the anaesthesiologist will know to shoot some more drugs into me to knock me out. How simple is that?
