Sorry 009, I am so used to using shorthand I forget not everyone is clued up, my fault, not yours.
OFP = Optimal Foetal Positioning, see www.homebirth.org.uk/ofp.htm. The Heath Care Professionals say it's not proven but anecdotal stories back it up and it sounds logical to me. I'm hoping to get to a workshop at the end of the month to hear Jean tell us all about it!
OP = Occiput Posterior, which means baby's back to mother's back
Brow presentation can also be called head deflexed, I think. Having had this myself I looked into this a bit. It's important not to break waters artificially as then the cushioning surrounding the baby is gone. And so if baby needs to tuck it's head in it will find it very difficult to do so without amniotic fluid, and it cannot rotate to Occiput Anterior very well either, it's not impossible, just unlikely without a lot of effort and time, and we all know you don't get given much time by the Health Care Professionals.
From what you've told us you had quite a classic story leading to CS, which is good because next time you will know what to avoid!
DD's hr dipping during contractions is normal, babies are designed to deal with normal contractions and their hr may well dip. If they remain dipped in between contractions then there should be cause for concern and different postions adopted to try to prevent it reoccuring, as baby could be lying on cord for example.
does this help you understand? Keep asking the questions!
