I read the article yesterday, and the line about CRNAs being "unsafe" immediately jumped off the page at me.
Vogue does not post articles at its online site, so I can't provide a link. But the focus of the article is re-thinking the safety of elective cosmetic surgery after two deaths at Manhattan Eye, Ear & Throat Hospital. (considering the risks of surgery? what a concept! who knew?!

)
Two excerpts:
"... Though suspected as the culprit in many complications, anesthesia is "actually very safe," says Abergel (***Santa Monica surgeon R. Patrick Abergel, MD***) "The new drugs are shorter-action, so you're not under as long." Just as you would investiage your doctor, you should also inquire about the anesthesiologist. "It's not illegal for surgeons to administer anesthesia themselves, and a lot do -- or they work with nurse anesthetists. Both are unsafe," says Abergel. Prior to surgery, a patient should comprehensively discuss her medical history, as well as the type of anesthesia to be administered with the anesthesiologist: will she be intubated and asleep under general anesthesia or conscious under local anesthesia? Doctors caution against anything but these two options.

"Although Olivia Goldsmith's death is still under investigation, it is rumored that she was taking both mood stabilizers and homeopathic supplements, either of which could have had adverse reactions with anesthesia, causing oxygen deprivation, which may have contributed to her death. "
