I don't think it normally is screaming, especially since labor would not be induced. (that creates extra-strong contractions when the tissue hasn't yet softened up) Typically it would be weird patterned breathing and loud statements like "GET THIS BABY OUT OF ME" or "I WANT THIS OVER WITH".
Lots of my friends have had horrid hospital experiences. One had a doctor brutally cut her with a scissors, from her vagina almost to her anus, cutting across all sorts of tendons and meaty bits. (this can cause anal incontinence) She later learned that he was trying to get out of there to not miss his golf tee time. My wife had a similar situation due to the doctor wanting to deal with his flooding house; thus we did our later births elsewhere. Doctors are definitely humans with their own priorities.
