Objective: to know nurse-midwives’ perceptions about factors related with the use of non-invasive care technologies in the care of high-risk parturient women. Methods: qualitative study, with 10 nurse-midwives from the obstetric center of a high-risk maternity hospital in a university hospital. Data were collected by semi-structured interviews and subjected to content analysis. Results: prenatal care with a focus on female autonomy, the availability of specific materials and the sector’s infrastructure are facilitating factors. Work overload, the devaluation of nurse-midwives’ knowledge by some medical professionals and the lack of institutional support for teamwork are limiting factors. Conclusion: the factors referred to show the need to boost collaborative work in assisting high obstetric risk, encourage the use of non-invasive care technologies and improve nurses’ working conditions.
