imip, so sorry to hear your experience, it is truly awful
.
OP, I used to be a midwife and in the 15 years I worked I can only recall one episode of cord prolapse. On that occasion it was obvious as the cord was prolapsed outside of the birth canal and visible. The Mum was no due for several weeks and her baby was born by caesarean section.
In the event of a cord prolapse there are few options available apart from emergency delivery of the baby. Internal examinations are a very inexact science....like mining in the dark. You have to be able to visualize what you are feeling if that makes sense. It isn't always clear cut either when you are not feeling usual stuff. In my time I have felt placenta
due to an undiagnosed placenta praevia (it wasn't clear what I was feeling but I knew it was not the baby's head), bottom (undiagnosed breech), and a foot (footling breech).
Because cord prolapse is so rare I have never experienced finding this on internal examinaton but I do know that if I was in any doubt I would err on the side of caution. I am also curious to know if anyone else did an internal to confirm cord prolapse or if they took the word of the midwife in question?
Whatever happened, it sounds as though it was very traumatic for you and at the very least you need someone to go through your labour and delivery records and answer any questions you might have. You have a live baby and that's great but the birth trauma can impact upon what should be a very happy time for you (if exhausting) and as such you need to have any nagging lingering questions resolved so you can get on and enjoy your baby.
To answer your questions..
1, It is hard to diagnose if not obvious and a lot would depend on the experience and skill of the midwife involved. It is rare so if a midwife feels "something" unusual on internal examination then it can be open to her interpretation of what that is. If what she is feeling is pulsating....is it the edge of a lower lying placenta, is it a cord, is it something else?
2.You might only need one internal examination to diagnose if it is obvious, I was always taught that once you have identified a cord prolapse you get the Mum into a position which reduces pressure on the cord. If it isn't obvious/the midwife is unsure then they could ask someone to check...as long as there are no obvious signs of fetal distress. If I was unsure but there were signs of fetal distress then I would always err on the side of caution.
- Reassure the Mum by explanation....not sure you can reassure someone adequately in this situation as it is a real emergency but I would always explain exactly what I could feel and what needed to happen.
- In theatre the role of the midwife would really be to support the Mum unless of course there is short staffing and the midwife is needed to play another role. I have lost count of the times I was asked to go and scrub to assist the surgeon...meaning my support of the Mum was taken over by someone else. Not god continuity but that's how it is sometimes.
Hope that helps a bit....it's been 10 years since I was a midwife so some things may have changed. Hopefully someone with ore recent experience will come along.
