This study aimed to describe the nurses' perception regarding the Emergency Care Units. It is descriptive research with a qualitative approach. The study participants were 25 nursing professionals from the Emergency Care Unit of a municipality in Santa Catarina who voluntarily accepted to participate in the study. The data were collected through interviews and were submitted to the operative proposal for analysis of qualitative data. The results show the professionals' understanding in relation to the purpose of these units, but indicate the incorrect way that this service is being used by the population; a fact that - added to the lack of materials, standardization of procedures, human resources and training - hinders the work process. It is suggested that continuing education may be used as a means for articulating the team and the search for quality work.
