According to Huffingtonpost:
The New York City Medical Examiner has finally revealed that lack of oxygen to Joan Rivers' brain caused her death over a month ago.
According to the medical examiner's report, her death was officially caused by "anoxic encephalopathy due to hypoxic arrest during laryngoscopy and upper gastrointestinal endoscopy with propofol sedation for evaluation of voice changes and gastroesophageal reflux disease."
I had wondered if the endoscopy center was using propofol, I have admitted several anoxic brain injuries from some area endoscopy centers that used propofol. How many more people must die or have significant brain injury before people wise up that NAPS is not safe. I am not an anesthesia provider, nor do I pretend to be, if you need anesthetics in a procedure get an anesthesia provider.
