[Autonomy in intensive care unit: let us start by caring ourselves]

This study, a qualitative investigation anchored in Foucaltian analysis with approximations to post-structuralist theory, explores the question of autonomy as one of the tensions of nursing performance/knowledge which can be discursively articulated to bioethics and to techno biomedicine. From such perspective, from the multiples vies that may emerge to completing a critical reading of the analyzed texts (articles produced by nurses) and of the interviews with intensive care nurses, the theme of autonomy was analytically explored from the concept of self care, unfolding itself into categories which express privileging: morals as obedience to the Law; conduct and morals concerning technical knowledge; self-governing in its confront with technique. These are configured as ethical possibilities for the intensive care nurse/subject, not as sequential or competitive stages, but connected and confluent in the experience of the current historical period.
