I tried to add this to my first post several times... even tried to post straight after but it wouldn't let me (grr!). This is what I wanted to add:

ETA: Oh and I have read the frequently posted questions post.... I started this thread to get help for my specific situation, iykwim?

Intrauterine hypoxia — lack of oxygen — can be both a reason for performing a Caesarean section and a cause of death, but even eliminating those deaths left a neonatal mortality rate for Caesarean deliveries in the cases studied at more than twice that for vaginal births.
I am wondering if this is what happened to my older brother who died whilst Mum was in labour. No autopsy was performed (at my mother's request) so it is written down that he died of "inoxia" (sp?). Either way, my mother was never given a reason (nor was she allowed to see her baby, her first born... but that's a whole other thread!).
