You'd be surprised, I have seen many a hospital midwife do the whole super fast third stage thing. One of my clients had a quick pushing stage and the midwife whipped out the syntometrine shot, and my client said with horror, OMG whats that for (we'd not had a birth plan meeting, it was all very last minute but she had an awesome birth!) and before the midwife answered she'd already put it in her leg and then said, to stop a haemorrhage. Hmmmmmm.
