Upon notification, the corresponding author is responsible for the evaluation of the subject matter and all other authors must agree with it. The corrections must be submitted within 30 days. If there is a delay in returning the proof, the Editor-in-Chief reserves the right to publish independent of the final correction or exclude from the editorial process.

After this evaluation, all articles proposed for publication will be previously submitted to the analysis of two or more members of the Editorial Council or other Specialized Consultants.

The anonymity of reviewers and of the authors is preserved throughout the whole process. The reviewers' comments will be sent to the authors to guide the changes to be implemented in the text. After implementing the changes suggested by the reviewers, the revised manuscript should be resubmitted along with the specific indications of any changes made to the text or the reasons why the changes were not made. The manuscripts accepted will be subjected to minor corrections or changes which do not alter the author’s style.

Possible modifications in format, style or interpretation will only be carried out after previous consultation.
If denied, articles will be returned with a justification of the Editor-in-Chief.

The ultimate publication will be based on the final approval of the editors.

OBS: Author and coauthors shall sign and send during the submission process a Copyright Cession Form to Sociedade Brasileira de Anestesiologia and Elsevier Editora Ltda. These forms shall be sent as separate documents (one form per author), as PDF files, through the submission system.

Legal an Ethical Considerations: according with Uniform Requirements for Manuscripts Submitted to Biomedical Journals (International Committee of Medical Journal Editors — February 2006).

Conflict of Interest
Conflict of interest exists when an author (or the authorís institution), reviewer, or editor has financial or personal relationships that inappropriately influence (bias) his or her actions (such relationships are also known as dual commitments, competing interests, or competing loyalties). These relationships vary from those with negligible potential to those with great potential to influence judgment, and not all relationships represent true conflict of interest. The potential for con flict of interest can exist whether or not an individual believes that the relationship affects his or her scientific judgment. Financial relationships (such as employment, consultancies, stock ownership, honoraria, paid expert testimony) are the most easily identifiable conflicts of interest and the most likely to under mine the credibility of the journal, the authors, and of science itself. However, conflicts can occur for other reasons, such as personal relationships, academic competition, and intellectual passion.

Informed Consent
Patients have a right to privacy that should not be infringed without informed consent. Identifying information, including patientsí names, initials, or †hospital numbers, should not be published in written descriptions, photographs, and pedigrees unless the information is essential for scientific purposes and the patient (or parent or guardian) gives written informed consent for publication. Informed consent for this purpose requires that a patient who is identifiable be shown the manuscript to be published. Authors should identify Individuals who provide writing assistance and disclose the funding source for this assistance.

Identifying details should be omitted if they are not essential. Complete anonymity is difficult to achieve, however, and informed consent should be obtained if there is any doubt. For example, masking the eye region in photographs of patients is inadequate protection of anonymity. If identifying characteristics are altered to protect anonymity, such as in genetic pedigrees, authors should provide assurance that alterations do not distort scientific meaning and editors should so note.

When informed consent has been obtained it should be indicated in the published article.

Ethical Treatment
When reporting experiments on human subjects, authors should indicate whether the procedures followed were in accordance with the ethical standards of the responsible committee on human experimentation (institutional and national) and with the Helsinki Declaration of 1975, as revised in 2000. If doubt exists whe ther the research was conducted in accordance with the Helsinki Declaration, the authors must explain the rationale for their approach, and demonstrate that the institutional review body explicitly approved the doubtful aspects of the study. When reporting experiments on animals, authors should be asked to indicate whether the institutional and national guide for the care and use of laboratory animals was followed.

Clinical Trials Registry
Clinical trial must be register according WHO recommendation at The definition of clinical trial include preliminary trials (phase I): any study with prospective recruiting of subjects to undergo any health-related inter vention (drugs, surgical procedures, equipment, behavioral therapies, food regi men, changes in health care) to evaluate the effects on clinical outcomes (any biomedical or health-related parameter, including pharmacokinetics measure ments and adverse reactions).

The Journal has the right of not publishing trials not complying with these and other legal and ethical standards determined by international guidelines.

Throughout its 51 years, Revista Brasileira de Anestesiologia has counted on the cooperation of laboratories and anesthesia equipment manufacturers just in advertising their products without interfering in the scientific publications.


It is worth underlying that Revista Brasileira de Anestesiologia is managed by The Brazilian Society of Anesthesiology itself, which has a budget and the statutory duty of publishing the journal without the need of selling ads. So, the periodicity of the journal is not dependent on money coming from advertisers. The budget proposal of the Society takes into account expenses with the publication of regular editions of the journal which is paid using part of the members fees.

There is no fee for submission and review articles.

The Journal adopts iThenticate system for plagiarism identification.
