There are some dodgy dental practices around here. Some of the CRNAs I know used to work with one that would schedule ANYBODY including some really abnormal special needs kids, didn't have qualified PACU staff, and had poor and outdated equipment. They'd tell me stories of nasal intubations for fat syndrome kids they'd extubate and drop off in a "PACU" before rushing the next one into the procedure room. It's anesthesia for airway surgery at a remote location in patients screened by a dentist and you may be very alone.
The generous hourly rate is the dentist buying malpractice coverage off you, essentially. Visit the place and see how it's set up.
