The model of obstetric care predominant in Mexico in most public and private healthcare institutions is particularly focused on a physiological perspective of the female body that does not respond to women's need for emotional comfort and satisfaction. In the last decade, however, various initiatives that provide obstetric care centered on women's rights have emerged. To analyze the implementation of a model of humanized/respectful delivery care supervised by nursing and midwifery undergraduate interns in a birthing center in the state of Chiapas, in order to identify achievements and future challenges. We used information from secondary sources and carried out a descriptive analysis. Births attended at the birthing center increased in relation to all the births registered in the Angel Albino Corzo municipality between 2017 and 2022. Positive indicators of respectful care increased with the implemented model, while negative indicators decreased. Between 2016 and 2022, obstetric nurses attended more than 1500 births without maternal deaths and managed some emergency cases referred to specialized care. This case illustrates the potential of alternative models of obstetric care. Evidence-based, midwife- and nurse-led models of clinical obstetric care should be expanded in the Mexican healthcare system.
