I'm not a doctor and I wasn't there, but generally if the baby has a very slim chance of survival, and if the health care in question would only prolong the child's suffering, yes. From gunga's link:
Experts on medical ethics advised doctors not to resuscitate babies born before 23 weeks in the womb, stating that it was not in the child's 'best interests'.
The guidelines said: 'If gestational age is certain and less than 23+0 (i.e at 22 weeks) it would be considered in the best interests of the baby, and standard practice, for resuscitation not to be carried out.'
Medical intervention would be given for a child born between 22 and 23 weeks only if the parents requested it and only after discussion about likely outcomes.
But while survival rates for those born after 24 weeks in the womb have risen significantly, the rates for those born earlier have barely changed, despite advances in medicine and technology.
Medical experts say babies born before 23 weeks are simply too under-developed to survive, and that to use aggressive treatment methods would only prolong their suffering, or inflict pain.
The guidelines were drawn up by the Nuffield Council on Bioethics after a two-year inquiry which took evidence from doctors, nurses and religious leaders.
Studies show that only 1 per cent of babies born before 23 weeks survive, and many suffer serious disabilities.
Further, the example they cite to demonstrate that the baby would have been given care in the US contradicts that claim:
Amillia Taylor was born in Florida on October 24, 2006, after just 21 weeks and six days in the womb. She celebrated her second birthday last year.
Doctors believed she was a week older and so gave her intensive care, but later admitted she would not have received treatment if they had known her true age.
Further, if the child had been born in the US to a 23 year old mother who already had a 5 year old child, meaning it is unlikely she had the means to pay for the care and would likely have been using Medicaid to pay for the treatment, I'm sure some people would be singing a different tune.
Every woman cooks babies differently, so I think there should be some wiggle room around these gestational deadlines, but the doctors there could have made a different call if it looked like the baby's chances were good. They didn't.
