The propofol thing again-- the article that says she was "Michael Jackson-ed" to death-- I don't know if I can agree with that.
There is no hard and fast "dosage" for propofol used as sedation/ "deep sedation-pretending-not-to-be-general-anesthesia."
The issue is how was it dosed-- by little "bumps" from a hand held syringe, or in a drip on a pump? And we have no idea how long they diddled around in that endo suite.
The issue of not weighing her was an omission, for sure-- but professionals have to guesstimate weight every day of the week, especially in emergency situations (and for sure, this was an elective procedure). I'm not as worried about the lack of weight documented-- the anesthesiologist should have been able to guesstimate within 10-15 pounds of her actual weight. She wasn't that big.
