Having worked in a tertiary care children’s hospital for more than a decade, yes I do think this is a case for a CRNA. The CRNA here was working with a physician anesthesiologist, by the way, so if the “mid level” provider was in over his head, where was the all-knowing doctor?
Was the CRNA working with an actual MD anesthesiologist, or just working under their license, so the MD gets sued, too? That is what is happening nowadays. Hospitals hiring midlevels, and forcing the MDs to be liable for them. If you are working as a midlevel, you should be responsible for your own errors. Right now, nurse practitioner training is largely online. When they graduate, they rely on an actual MD to train them. Its a dumbing down of healthcare. Know who is treating you. It may save your life. They are called noctors, not doctors.
