That sounds similar to one paper that I read during my Midi and Paeds section at uni... I will not be allowing the injection unless I have to have (another) forceps delivery... which are alarmingly common at the hospital I have to do to. Oh the joys of being a high risk delivery. I much prefer the little country hospitals, but they just will not cater for people with all my medical issues. I don't understand (or like) it, pregnancy, labour and breastfeeding are three things our body is trained to do... so why all the medical intervention???
