What causes some gynecologists to put women under anesthesia for a regular pelvic exam?

That's unusual.: The only patients that i've ever anesthetized for a pelvic exam were children. It would be extraordinarily unusual for a patient to need anesthesia for a routine pelvic exam. I could understand however that some women with very painful conditions or a history of a traumatic experience may benefit from some sedation prior to their pelvic exam, but not a general anesthetic.
