It would be nice if they gave her something but I wouldn't bother requesting for anything. It just makes her look bad. It's really the person who got rescued that might want to thank the doctor, not the airline itself. Though it could be argued that it saved the airline sometime and money to turn around, but it also saved your wife and other passengers the time to not turn around.
It does suck that the crew did not communicate with the ground staff and left her there hanging after speaking with the paramedics. But, if doctors are really all about getting something in return for rescuing others, might as well just sit on your chair and don't help. Right?
