Until the end of XIX century, in Colombia, birth attendance was an exclusive female responsibility. Since XX century, the increase in hospitalization for birth attendance leads to the medicalisation process, involving the positioning of gynecological-obstetrics as exclusive dominion and limiting in turn the nursing inclusion. Therefore, the doctor-nurse relation has been interfered with by roles distinction, superiority perception, limitation of functions and the no specialization on obstetrics nursing. Objective: Describing the nursing role at low risk birth attendance in Colombia through obstetrician-gynecologist and nursing professionals’ social representations. Method: qualitative research of phenomenological approach of a descriptive nature addressing the Social Representations Theory by Serge Moscovici. Results: four categories were identified in which the main nursing and gynecological-obstetrics representations are described with regard to the birth attendance by nursing in Colombia, identifying advances, deficiencies, roles between professions, body of knowledge and current necessities to implement a new obstetric care model in Colombia. Conclusions: research showed that the nursing role at birth attendance in Colombia has been limited by processes as medicalisation, hierarchization between professions, political ideologies, cultural practices, loss of autonomy in nursing and lack of knowledge and expertise in the area. Likewise, a gap in the professional nursing training in obstetrics was described, as well as, acknowledging the necessity of implementing a new obstetric care model in the country.
