The main goal of this research is to make an institutional analysis of the discourse of a group. For this assignment a São Paulo's public teaching hospital was chosen. The focus of our analysis is the relationship the professional has with his work, using the Institutional Analysis of Discourse, developed by Guirado (2010), as a conceptual and methodological reference. This research will demonstrate that the professionals' relationship with their work is tangled up by procedures, majorly composed by administrative and caring procedures (for nurses and auxiliary nurses, respectively). The blending of procedures and relationship disguises the differences between being and doing, leading in turn to the nurses' identification with the mother's role, to the indiscriminateness' of their relationship with the patients, and to an increased difficulty when defining the limits for their practice and their feelings. In that case, death is for them the only inexorable limit, one that promotes the disruption and reorganization of themselves and their relationship with the work. Death is also able to promote trauma, paralysis, repetition, and panic. The mother is seen, by the child, as a true and only haven. If the mother is good, she is considered the foundations for life, health and happiness of the child. When she is bad or absent, this is considered the reason for the child's untidiness, fragility, illness and death. The mothers are, simultaneously, institutional agents and clientele, since the nursing work presupposes the work of the mother. The amount of work attributed to that staff is lessened in the presence of a good mother and enlarged when dealing with a bad mother. The child appears as object and target of the nurses' action and as subject and product of your mother. The dispute for power (and its resistance) in the contacts with the doctors occurs through the polarization between making the child to live or leaving the child to die, in which the resistance implies taking over the doctor's job, "take conduct" and making the child to live. With the professionals in the domain of Justice, these games of power/resistance occur concerning the sentence about the child's future. Nevertheless, nurse professionals, kept away from the "process", resist by judging the judgment. Irony, disqualifying, indictment and boasting, lack of commitment, and the blurring of limits and boundaries are the primary resistance strategies which they employ. On the other hand, acting as institutional functioning support maintenance we have a rigid hierarchic structure, juridical and management proceedings, punishment and "discussion", and pacification (whose role was fulfilled by the group here studied). At last, the maintenance and control of all patient's alterations and movements (physical or physiological) was configured as the institutional object for the nursing work. This was achieved by means of monitoring and surveillance technologies, rewards and punishments.
