Should they have called an ambulance to get the baby to Neonatal Intensive Care ASAP?

FWIW there is a soon-to-be-published trend in the First World for nurses to refuse to take part in late abortions or second trimester abortions like this one. Not even the higher payment traditionally offered to abortion workers (which is an interesting issue in itself) has slowed this trend. Perhaps this episode offers a brief glimpse of the nurses' reasons.

For the record: the reason her cervix was dilated is because a fetus is too large by this stage to be simply scraped/sucked out. Instead it needs to be dismembered and the pieces pulled out. Beyond 21 weeks it may be necessary to crush the skull as well to expedite extraction. The problem this time was that a live fetus was delivered before it (she?) could be dismembered in utero. Perhaps the OP is wondering why the subsequent treatment is worse than what was intended.
