Shit shit shit, Nevil, just seen this and remembered that I was supposed to some back to this thread ages ago to talk to you about my VBAC with anti-E. I am so so sorry.
Right, here we go. I had anti-E ABs during my third pg, highest level at any time was 1:64, fluctuated between 1:16 and 1:64. I was scanned by the Fetal Medicine guys every 4 weeks (and sometimes more often, depending on the results) to check the cranial artery blood flow. On one occasion, this increased quite dramatically (though still within the limits of normal) so I was scanned weekly until they were convinced that it was an aberration. There was never any suggestion that I should deliver early, though they did not want me to go over 40 weeks. There was no mention of the placenta, just that it would be easier to treat any HDN outside the womb rather than in. I had my final scan 2 weeks before the baby was due, they booked me for induction the day after my due date and sent me off, saying they hoped to see me before then. Oh, and they also said that for Anti-E, there was no correlation between titre levels and the incidence of HDN, so I could have high titres and have no problems.
I tried to discuss my birth with the Fetal Medicine cons, and he was hopeless . However, he admitted this, and sent me off to talk to the consultant MW and obs about it all. Both the MW and the Obs saw no reason why I should not labour in water with the telemetric CFM equipment (though they did point out that the pool/monitor might not be available if someone else was using it). The Obs did want me out of the pool for delivery, but this was because I had post-partum haemorrhage with my VBAC with DD2, rather than anything to do with the scar rupture etc.
In the end, I did not go into spontaneous labour with DD3, so was induced at 40+1. They tried ARM first which did bugger all, then went to syntocinon drip. I had an epidural first though. I dozed through my labour (and DH slept) until the pressure became quite intense. MW checked, 10cm dilated, DD3 born after 29 minutes pushing. I had 2 small stitches, mainly because the scar tissue from the second degree tear with DD2 would not stretch.
DD3 was wonderful for the next 12 hours though with hindsight she was very sleepy and did not feed well. She was taken to SCBU approx 12 hours after birth and placed under triple light theapy, where she remained for the next 4 days. It was not easy - she was fed by NGT, so I had to express milk for her. I also wasn't well-prepared for it as I had thought the HDN would be immediately apparent on birth - it is not, it can develop over time. She came out of SCBU on a Bilibed for 2 days then we spent another day in hospital while they made sure that her bilirubin levels did not bounce back up once she was off the light therapy. Finally, we went home.
I cannot see why you need to deliver at 39 weeks - can I ask what hospital you are at? This post has turned into a complete epic, and I'm not sure if I'm giving you the infor you want/need, so I am going to stop here and you can let me know if there's anything you would like to ask me.
