“…They might have great difficulty, however, in detecting an alteration in the growth rate of the baby and they would not be able to apply an accurate objective standard, which serial cephalometry provides. (Willocks et al 1967) Let us see how this transformation was performed, so that the measurement was abstracted from clinical experience in this way. The feat was accomplished by fitting a regression equation (y = a + Bt) to the individual's set of measurements.…”

The process of technological change in obstetrics must be understood as contingent on the exigencies of the professional project, rather than in terms simply of improvement or dehumanization of care. Transformation in the procedures by which the female pelvis and the fetal head have been measured illustrate this point. The development of new measurement techniques was profoundly influenced by the shifting locus of obstetric care and by changing professional concerns, including the initial demarcation of a professional practice and subsequent debates about preferred modes of intervention .Prior to the seventeenth century, processes of pregnancy and childbirth were almost exclusively the concern of women. The major role in the delivery was played by the mother herself, assisted by a midwife, almost certainly a woman. In the course of the seventeenth century, the practice of midwifery began to be regulated in many European countries, and educational requirements were imposed. Teaching, largely in anatomy and examination of candidate-midwives were made the responsibility of university-educated doctors. Through the seventeenth and eighteenth centuries the authority of (male) doctors in this traditionally female world grew. Doctors had the advantage of access to instruments with which they claimed they could bring difficult deliveries to successful conclusion. Midwives were often denied use of these instruments. Obstetrics was introduced into the university education of physicians, although normal deliveries remained the prime responsibility of midwives.Today pregnancy and delivery have largely become a matter for (mostly male) doctors, deploying a wide range of sophisticated technologies. Moreover, in modern obstetrics the fetus has become a patient in its own right -

“…Early in the dcvelopment of the method, two pcaks in thc echogram [4, 64,80] were thought to bc sufficient. Howcver, it was seen that this allegcdly typical echogram of the biparietal diametcr was also found with other cranial diameters, e. g. thc fronto-occipital diameter or when the beam traversed the fetal skull obliqucly [20], 1t was found that thc biparietal diameter was characterized by a three-peak echogram whereby the middlc echo corrcsponded to the reflection of the sonic beam from the falx cerebri or the interhcmispheric fissutre [42,46,76].…”

“…Willocks et al (1964) showed that there was a correlation between birth weight and the ultrasonic measurement of the biparietal diameter before birth, and others have used the technique for measuring fetal Free University of Brussels, Belgium P. FLAMME, M.D., Assistant, Obstetric and Gynaecological Clinic growth (Thompson et al, 1965). Also serial measurements of the growth rate of the biparietal diameter have shown it to be related to fetal maturity (Willocks et al, 1967).…”
