Sadly but inevitably, the clinical fruit of all scientific research, like the profile of the Roman god Janus, presents us with two faces - one is patient benefit while the other is medico-legal vulnerability. As part of defensive medicine, there are situations where malpractice risk is minimised by actual elimination of certain high-risk procedures e.g. in the case of some neurosurgical operations. Intra-partum electronic fetal monitoring (IPEFM) is the commonest obstetric procedure in the developed world, producing valuable information of fetal well being as co-related to maternal uterine activity with a scope of guarding fetal well-being in labour. It is a prime example of the therapeutic/ legal liability duality which haunts modern Medicine.peer-reviewe
