I had my son 21 years ago in England, and I have no recollection of having an IV. In fact, I'm sure I didn't. I didn't have any pain relief: was throwing up so couldn't have gas and air, and I don't think I could have had an epidural even if I wanted one. Can't remember why--possibly because I was 4 cm when I came in and the kid wasn't hanging about? Anyway, childbirth was a particularly foul experience for me. Wasn't allowed to go to the bathroom in case I had the child in the toilet, so they put a bedpan on a rocking chair--yes, a rocking chair. Then, whilst using bedpan on rocking chair, I started to throw up. Then, whilst throwing up whilst using bedpan on rocking chair, student doctor came in and said he'd like to help with the birth. I believe I was somewhat foul and ordered him out. Kid's shoulders got stuck and I declared I couldn't have the baby, I just couldn't do it. So the midwife said that was all right, she'd send me home on the bus. Then after the baby was born, the placenta didn't come out....
But did I have an IV? Nope.
