I found more details on Dallas County Civil Court’s website
The expert witness testimony fills in some of the details
Basically, Houghton is under the supervision of Baber Younas, MD, who is an anesthesiologist who seems to have grandfathered himself into interventional pain without doing a fellowship. This might explain why he hired a CRNA to begin with, he didn’t get formal training himself so he has no respect for the process.
Autopsy showed focal hemorrhage and distension of the dura with CSF, so had she survived Mrs Ray would likely have been paralyzed.
However in a brilliant stroke of incompetence, the CRNA providing anesthesia, Molina, had a documented history of substance problems and impairment at work x2 (known to Texas nursing board). He straight up administered a whopping 200mg of propofol and 100mcg of fentanyl to Mrs Ray for the RFA at the beginning of the procedure. For the non-anesthesiologists, that’s an intubating dose for a big dude. No one breathes through that. (It’s such a mind-boggling dose that I’m wondering if our substance-abusing friend actually gave her less than that and squirreled away the rest for his own fun later? But that probably wouldn’t help his case to say he falsified the records to support his habit).
So poor Mrs. Ray got a one-two punch. The first CRNA suffocates her. The second CRNA spears her spinal cord.
This is actually a good case of greedy doctors supervising unqualified CRNAs to do procedures and make more money.
