Theoretical-reflexive study motivated by the epistemology of Gaston Bachelard and by the project "Thousand and one ways to take care in Nursing" by Maria José Coelho. We had as objective to trace new ways to take care in dialysis nursing, creating a system of cares offered to chronic kidney patients. Seven nursing cares that involve care of people in dialysis treatment were described: reception; bonding; specialized techniques; support to self-care; assessment of the treatment, facing the unstimulating routine; and citizenship rescue. Permanent care emerged, understood as an articulate and complementary relation between the scientific knowledge present in nursing care and the valorization of the other's essence, as a complex being in its whole.
