We have OMFS residents for 3 or 4 months at a time. They are all very bright and have a good time with us. Don't forget that in the US, dentists were way ahead of physicians in administering anesthesia. Of course in the case at issue, there was an anesthesiologist present. I agree with the no pulse ox. Probably some combo of midaz/fent/propofol, inadequate resuscitation equipment, possibly an equipment malfunction. Of course I could be way off on this, maybe they had full ASA monitors and an anesthesia machine and the kid just had laryngospasm when they got underway.
