Abstract
Objective: Review the influences of Principialist Bioethics (PB), the Federal Constitution of 1988 (CF88) and the National Curriculum Guidelines for the 2014 Medical Undergraduate Course (DCNs), on the characteristics of the doctor-patient relationship, in front of the client Witness of Jehovah (TEJ), in refusing blood transfusion. Methods: An integrative review was carried out, through a search for published articles, in the online databases Pubmed and SciELO, in the period 2010 to 2021. Results: The inclusion of 30 articles, recruited through the PRISMA protocol, identified that PB influences the guarantee of the TEJ's right to religious freedom and health provided for in CF88. In addition, the role of the DCNs was observed, in aiding humanized medical training, in the relevance of the health work process, guided by bioethics, and in the doctor-patient relationship, in the face of disagreements, regarding health procedures. Final considerations: There is currently no room for medical paternalism, and it is certain that, as important as treating bodily ailments, is also respect for the limits imposed by the sanctuary of the patient's individual conscience.
