"[I]n the previous report, it was recommended that the use of analgesia be considered where the fetus was over 24 weeks of gestational age. However, this more recent review has concluded that the evidence that the fetus can and does experience pain is less compelling and accordingly the benefit of administering analgesia is less evident, while the risks and practicalities of so doing remain. So on the basis of ‘first do no harm’, prior to the procedures described in this report, analgesia is no longer considered necessary, from the perspective of fetal pain or awareness."
