Social and professional influences of the technology of electronic fetal monitoring on obstetrical nursing.
Electronic fetal monitoring (EFM) is one example of a biomedical technology that rapidly diffused from an experimental innovation into a standard medical practice. First developed in the 1950s, EFM became commercially available in the early 1970s and quickly transformed intrapartum obstetrical practice. Assessments and interventions, which practitioners had previously based primarily on laboring women's subjective reports of bodily sensations, were now being based on quantifiable objective data from uterine activity and fetal heart rate transducers. Despite concerns of over-medicalization of the natural event of birth, iatrogenesis related to the increased incidence of operative deliveries, and escalating costs, EFM became widely accepted as routine and necessary by both practitioners and patients. By presenting the confident expectations and cautious reservations of various practitioners and patients to EFM, this article explores the rapid diffusion of EFM within the social context of the 1970s. A special focus is given to the perspective of intrapartum obstetrical nurses, because they have been the primary users of this perinatal technology since its introduction.
