I think a case of severe medical negligence has been complicated by the fact that the husband has come out and said they requested, and were denied, a termination.
Hanging on and not removing a live foetus is in accordance with the law in Ireland. It is a law many people disagree with, understandably, but it is the law. It is not medically negligent to do this and the chances are the outcome will be painful and awful for the woman (again, a matter of moral, rather than medical, debate) but unproblematic. Savita's life was not in danger when she entered the hospital, and once the infection took hold termination would not have cured it.
However, it is medically negligent not to monitor a woman who has an open cervix, and who has received internal exams, very closely. They should have given her prophylactic antibiotics, or at the very least, done very regular bloods to monitor the risk of infection.
They didn't do this, and as a result a simple EColi infection developed into septicaemia. The infection wasn't discovered until she collapsed. There is no way that should have happened in a modern hospital.
The issue wrt to termination is an incredibly important one, and I do believe she should have been able to have one, in order to spare her the pain of waiting for the baby to die. BUT not having an abortion did not contribute to her death. Medically it doesn't make sense to claim that it did.
Miscarriage is treated appallingly in Irish hospitals - you are basically expected to shut up and get on with it. It could also be the case that Savita was treated carelessly by staff who were annoyed at her foreignness and her repeated requests for abortion. This, of course, is utterly wrong.
But mixing up the abortion issue with her death is only going to muddy the waters. I'm glad people have a fire in their bellies over this. It would be a shame if the whole thing gets bogged down in unfounded accusations.
As others have pointed out there have been multiple referenda on abortion, all resulting in abortion on demand being prohibited. This is the free choice of the people of Ireland. There does need to be solid legislation on the X case but I think abortion is still a long way off for Ireland.
