Abstract

Objective: To analyze the scientific evidences related to the management of pleural and mediastinal drainage in postoperative of cardiac surgeries. Method: Integrative review, searching for articles published on databases: MedLine, LILACS, PubMed and SciELO. The referential scientific studies were read and classified according to the level of evidence, and after analysis, the relevant information was presented as a table. Results: Twelve articles were found in the PubMed database, published in English, with a predominance of level of evidence IV. Regarding the year of publication, 58.3% of the papers were published between 2003 and 2008, and 41.7%, in the last five years. Conclusion: Conclusion: Most authors recommend that milking should be performed only when a clot is visible; there are new proposals and technologies being instituted with the intention of keeping free flow in the drains; and about tolerable volume, available literature data are based on expert opinions, literature reviews or unsatisfying studies. In general, the subjects presented need studies in which protocols of use are established, encouraging the implementation of solutions for better results.
