About the journal


Basic information


In 1951, the Brazilian Journal of Anesthesiology (BJAN), then Revista Brazileira de Anestesiologia, was established as the official publication of the Brazilian Society of Anesthesiology, and in 2019, the Editorial Board decided the journal would be renamed as Brazilian Journal of Anesthesiology, in an internationalization process.

The journal was internationally acknowledged in the editorial entitled "A New Journal is Born" by Howard Dittrick, editor in chief of the Current Researches in Anesthesia and Analgesia [1951 Sept-Oct; 5 (30)].

The BJAN has been devoted to publishing original scientific manuscripts on Anesthesiology and/or correlated areas by national and international researchers. Its target audience comprises anesthesiologists who are members of the Brazilian Society of Anesthesiology and other physicians with interest in the area. The journal promotes the progress, improvement, and disclosure of anesthesiology, intensive care, treatment of pain, and cardiopulmonary resuscitation.

From 1951 to 1969, the BJAN was published every three months. Since 1970, it has been published every two months.

The BJAN was published in Portuguese and English from January 2001 to December 2020, and in Spanish between 2011-2015, electronically.

In 2021, the Revista Brazileira de Anestesiologia (0034-7094) was merged into Brazilian Journal of Anesthesiology (0104-0014), adopting English as its main publishing language.


2352-2291 Brazilian Journal of Anesthesiology (Online)

0104-0014 Brazilian Journal of Anesthesiology (Print)

The abbreviation of its title is Braz J Anesthesiol, which should be used in bibliographies, footnotes, bibliographic references, and legends.

Instructions to authors


Scope and policy


The Brazilian Journal of Anesthesiology (BJAN) is the official journal of the Brazilian Society of Anesthesiology (SBA), which supports the journal completely – the cost of publishing is on behalf of the Society, with no charges to authors.

The BJAN publishes original work in all areas of anesthesia, surgical critical care, perioperative medicine, and pain medicine, including basic, translational, and clinical research, as well as education and technological innovation. Special articles such as guidelines and historical manuscripts are published upon invitation only, and authors should seek subject approval by the Editorial Office before submission.

Manuscripts must be submitted electronically via BJAN’s online submission system, and the author will receive an email confirming the submission.

The BJAN accepts only original articles that are not under consideration by any other journal and that have not been published before, except as academic theses, preprints (which are permitted and encouraged), or abstracts presented at conference or meetings, which must be specified in the cover letter. A cloud-based intuitive platform is used to compare submitted manuscripts to previous publications, and submissions must not contain any instances of plagiarism. Authors must obtain and send the Editorial Office all required permissions for any overlapping material, and properly identify them in the manuscript to avoid plagiarism.

All articles submitted for publication are assessed by two or more members of the Editorial Board or external peer reviewers, assigned at the discretion of the Editor-in-chief or the Associate Editors.

This journal is peer reviewed with subsidized open access, given the Brazilian Society of Anesthesiology (SBA) pays for the publishing costs incurred by the journal. The review is double-blind. Authors do not have to pay for any Article Processing Charge or Open Access Publication Fee.

All editorial communications should be addressed to the Editor-in-Chief (E-mail:

Send of the manuscripts


Before submitting a manuscript, authors should read the present Instructions to authors carefully and adhere to them. Problems with submissions should be reported to the Editorial Office. Decisions on submissions are final and will take place in approximately 8–12 weeks.

English (American) is the official language of BJAN, which receives submissions in English and Portuguese. After acceptance, arti­cles will be indexed only in English and a version of it in Portuguese will be available at journal website.

If required, before the Acceptance of the article, the author must send it to a certified English review, such as American Journal Experts (AJE), Enago and Proof-Reading-Service (PRS).

The submissions must have the following elements: Cover Letter, Title page, Abstract with Keywords, Manuscript without author’s details (blind), Tables + Figures, BJAN’s Copyright and Agreement forms.

Our online submission system guides you stepwise through the process of entering your article details and uploading your files. The system converts your article files into a single PDF file used in the peer review process. Editable files (e.g., Word, LaTeX) are required to typeset your article for final publication. All correspondence, including notification of the editor’s decision and requests for revision, is sent by e-mail.

Manuscript evaluation policy


Double-blind review

BJAN operates a double-blind review process, thus the authors must remove from the text all data that can identify you (names, affiliations, etc.) or your institution. Reviewers will not know who is responsible for the work when they are reviewing, and the authors will not know who has reviewed their manuscript in any stage of the publication process as well.

All peer reviewers will be initially assessed by the Editor-in-chief for suitability for the journal. Papers deemed suitable are then typically sent to a minimum of two independent expert reviewers to assess the scientific quality of the paper. The Editor-in-chief is responsible for the final decision regarding acceptance or rejection of articles, which is final.



Ethics statement


Studies in animals

All animal experiments should comply with the ARRIVE guidelines and be carried out in accordance with local country regulation. It is fundamental to clearly indicate in the manuscript that such guidelines have been followed and upload the guidelines’ checklist. It must indicate: the sex of animals and, when appropriate, the influence (or association) of sex on the results of the study; the genotype, strain, source, and number of backcrosses and age of the animals studied.

Studies in humans

If the article involves the use of human subjects, the author should ensure that the research described has been carried out in accordance with The Code of Ethics of the World Medical Association (Declaration of Helsinki) for experiments involving humans. Authors should include a statement in the manuscript that informed consent was obtained for experimentation with human subjects. Privacy rights must always be observed.

The manuscript should be in line with the Recommendations for the Conduct, Reporting, Editing and Publication of Scholarly Work in Medical Journals and aim for the inclusion of representative human populations (sex, age, and ethnicity) as per those recommendations. The manuscript must contain data on the age (mean with range), height (m), weight (kg), sex (male/female, with numbers and percentages), criteria for selection, health conditions, among others that are significant to study results. Complex information is better to be presented in a table to facilitate the understanding of the data. Informed consent and patient details: require Institutional Ethical Committee or Internal Review Board (IRB) approval and informed consent documented in the paper. Appropriate consents, permissions and releases must be obtained when an author wishes to include case details, other personal information, or images of patients or any other individuals. Please indicate it was obtained, but there is no need to upload them, unless specifically requested by the journal.

Images: must be deidentificated and anonymized, and a specific signed authorization for publication should be obtained from the patient, legal guardians or family and submitted along with the manuscript or case report. If there is no written permission, personal details of any patient included in any part of the article and in any supplementary materials (including illustrations and videos) must be removed before submission.

Authors must keep written consent before submitting the article and not send copies to BJAN. If specifically requested by BJAN in exceptional circumstances (eg in the case of a legal issue), authors must provide copies of consents or evidence that such consents have been obtained.

Inclusive language acknowledges diversity, conveys respect to all people, is sensitive to differences, and promotes equal opportunities. Authors should make no assumptions about the beliefs or commitments of any reader. The text should present nothing that might imply that one individual is superior to another on the grounds of race, sex, culture, or any other characteristic, and should use inclusive language throughout. Authors should ensure that writing is free from bias.

Conflict of interests


All authors must disclose any financial and personal relationships with other individuals or organizations that could inappropriately influence (bias) their work. Examples of potential conflicts of interest include employment, consultancies, stock ownership, fees, paid expert testimony, patent applications/registrations, and grants or other types of funding. If there is no conflict of interest, then you must declare “Conflicts of interest: none”. For more informations: <>.



Clinical Trial Registry


Clinical research and Experimental trials

Primary clinical, observational, or experimental research information. Each kind of study will contain different elements. A copy or link of the ethical approval of the study, as well as its registry, must be submitted along with the manuscript. For a list of registry platforms for clinical trials, assess: <>. Brazilian researchers are advised to register at ReBEC.



Plagiarism and editorial misconduct


The BJAN accepts only original arti­cles that are not under consideration by any other journal and that have not been published before, except as academic theses, preprints, or abstracts presented at confer­ence or meetings. A cloud-based intuitive platform is used to compare submitted manuscripts to previous publications, and submissions must not contain any instanc­es of plagiarism. Authors must obtain and send the Editorial Office all required permissions for any overlapping material and properly identify them in the manu­script to avoid plagiarism.

For more information about Ethics in Publishing access:



Preparing the manuscript



The submissions must have the following elements: Cover Letter, Title page, Abstract with Keywords, Manuscript without author’s details (blind), Tables + Figures, BJAN’s Copyright and Agreement forms.

Cover letter

Focus on the novelty and value of the author’s work, the relation to the scope of BJAN, and stating why the editor should consider the article for publication. Specify that the article was not previously published (or if it was published as preprint or academic work). The cover letter will not be part of the final published manuscript.

Also, please indicate the count of words, tables, figures, and references of the manuscript submitted.


At the discretion of the Editorial board, preprints can be shared any time and will not count as prior publication but must be cited in the submission.

Submission declaration and verification

Submission of an article implies that the work described has not been published previously, except in the form of an abstract, as part of a published lecture or academic thesis, or as an electronic preprint. It also means that the manuscript is not under consideration for publication elsewhere, that its publication is approved by all authors and tacitly or explicitly by the responsible authorities where the work was carried out.

If accepted, it must not be published elsewhere in the same form, in any language, including electronically without the written consent of the copyright-holder. Your article will be checked by the originality detection service Ithenticate.

See “Multiple, redundant or concurrent publication”: <>.

Title page

  • The actual title and the running title. The title must be concise and informative, as it is often used in information-retrieval systems. Avoid abbreviations and formulae if you can. Write the title in the simplest way possible, thinking, “how would I search for this subject in a database or on the internet?”. It must include the study design.
  • Authorship, with the names, affiliations, ORCID and contributions of all authors, clearly indicating the corresponding author (who will be responsible for all the communications with the journal). If the authors still don’t have an ORCID, it can be registered. Copy or link for the Institutional Research Board approval of the submission and the link for the study registry.


An abstract, with the headings background, methods, results, and conclusion, should provide the context for the research and state its purpose, basic procedures (selection of study subjects or laboratory animals, observational and analytical methods), main findings (giving specific effect sizes and their statistical significance, if possible), and main conclusions. It should emphasize new and important aspects of the study or observations.


Provide a maximum of six keywords in alphabetical order and separated by commas to represent the content of the article. The descriptors or keywords should be based on DECS or MeSH.

Blind manuscript

Manuscripts should be subdivided into clearly defined and unnumbered sections. Each subsection must have a brief heading. Each heading should appear on its own separate line. Please send it as an editable word file (preferably Word).

  • Title
  • Abstract + Key words
  • Introduction

Provide adequate background, avoiding a detailed literature survey or a summary of the results. Specify the hypothesis which justifies the study. State the objectives of the trial.

  • Material and methods

Provide sufficient detail to allow the work to be reproduced. Methods already published in detail elsewhere should be indicated by a reference citation, describing the methods concisely, as the reader might not have access to the original protocol publication, especially if it is not open access. All modifications from the study protocol should be described.

  • Results

Results should be clear, concise, and contextualized. Avoid the repetition of data in the text and in the tables or figures.

  • Discussion

Explore the significance of the results of the study, without repeating them. Confront your data with previous findings, avoiding extensive citations and discussion of already published literature. Discuss the limitations of the study and critically justify them. Emphasize the importance of the study for the current state of art as well as the future perspectives related to the study.

  • Conclusions

The main conclusions of the study should be presented in a short Conclusions section.

  • Acknowledgements

Collate acknowledgements in a separate section at the end of the article, before the references. List those individuals who provided help during the research (e.g., providing language help, writing assistance, proofreading the article, etc.).

  • Conflict of interest statements and grants
  • References

All references must be presented according to the Vancouver Style, and journal names should be abbreviated according to the International Committee of Medical Journal Editors.

Indicate only references used in the text, numbered in Arabic numerals, in the order in which they are cited.

Check the maximum number of references according to the type of manuscript.

  • Citation

Check that all references cited in the text are in the reference list (and vice versa). References cited in the abstract must be complete. We do not recommend including unpublished results and personal communications in the reference list, but they may be mentioned in the text; if such references are included in the list, they must follow the journal's standard reference style, presenting, in place of the date of publication, “unpublished results” or “personal communication”.

Citation of a reference such as “in press” implies that the item has been accepted for publication.

  • Reference links

Increased discoverability of research and high-quality peer review are ensured by online links to the sources cited. In order to allow us to create links to abstracting and indexing services, such as Scopus, Cross-Ref and PubMed, please ensure that the data provided in the references are correct. Note that incorrect surnames, journal/book titles, publication year and pagination may prevent link creation.

Use of the DOI is encouraged and can be adopted to cite and link to electronic articles when an article is in press and full citation details are not yet known, but the article is available online. A DOI is guaranteed never to change, so you can use it as a permanent link to any electronic article.

Other topics

Funding sources

Identify who provided financial support and briefly describe the role of the sponsor(s). If the funding source had no such involvement, it should be stated as well. List funding sources in a standard format to facilitate compliance to funder’s requirements. (i.e., This work was supported by the CNPq [grant number xxxx] and FAPESP [grant number xxxx]). It is not necessary to include detailed descriptions on the program or type of grants and awards.

When funding is from a block grant or other resources available to a university, college, or other research institution, submit the name of the institute or organization that provided it.

If no funding has been provided for the research, please include the following sentence: “This research did not receive any specific grant from funding agencies in the public, commercial, or not-for-profit sectors”.


Define abbreviations that are not standard in this field in the first presentation in the article. Such abbreviations that are unavoidable in the abstract must be defined at their first mention there. Ensure consistency of abbreviations throughout the article.


Follow internationally accepted rules and conventions. Use the international system of units (SI). If other units are mentioned, please give their equivalent in SI.


Footnotes should be used sparingly. Use of references is preferable.


BJAN adopts ICMJE criteria for authorship.

Authors contributions

Each author is required to declare his or her individual contribution to the article. All authors must have materially participated in the research and/or article preparation, so roles for all authors should be described. The statement that all authors have approved the final article should be true and included in the disclosure statement.

All authors should have made substantial contributions to all of the following:

  • The conception and design of the study, or acquisition of data, or analysis and interpretation of data;
  • Drafting the article or revising it critically for important intellectual content;
  • Final approval of the version to be submitted.

Indicate all affiliations with a lower-case superscript letter immediately after the author’s name and in front of the appropriate address. Provide the full postal address of each affiliation, including the country name and the e-mail address of each author. If an author has moved since the work described in the article was done, or was visiting at the time, a “Present address” (or “Permanent address”) may be indicated as a footnote to that author’s name. The address at which the author actually did the work must be retained, as the main affiliation address. Superscript Arabic numerals are used for such footnotes. Author affiliations should be presented in increasing hierarchical order (e.g. Disciplina de Anestesiologia, Hospital das Clínicas HCFMUSP, Faculdade de Medicina, Universidade de São Paulo) and should be written as established in its own language (e.g. Université Paris-Sorbonne; Harvard University, Universidade de São Paulo).

Author identification

The ORCID (Open Researcher and Contributor ID) must be inserted in all authors’ profiles during the submission process. If any authors do not have an ORCID, they can be registered at <>. Please note that articles with missing ORCID’S will NOT be published.

Changes to authorship

Authors are expected to consider the list and order of authors carefully before submitting their manuscript and provide the definitive list at the time of the original submission. Any addition, deletion or rearrangement of author names in the authorship list should be made before the manuscript has been accepted and only if approved by the journal Editor-in-chief. To request such a change, the Editor-in-chief must receive the following from the corresponding author:

The reason for the change in the author list and

Written confirmation (e-mail, letter) from all authors that they agree with the addition, removal or rearrangement. In the case of addition or removal of authors, this includes confirmation from the author being added or removed.

Only in exceptional circumstances the Editor-in-chief will consider the addition, deletion or rearrangement of authors after the manuscript has been accepted. While the Editor-in-chief considers the request, publication of the manuscript will be suspended. If the manuscript has already been published in an online issue, any requests approved by the Editor-in-chief will result in a corrigendum.


At the moment of the submission, authors must upload, along with the article, a digital signed copy of two documents:

  • Author’s Agreement: by signing this Agreement, the Author(s), ensures that is the copyright owner and licenses to BJAN the exclusive rights of the manuscript submitted. If accepted, the Author assigns to BJAN the right to publish and distribute the manuscript in part or in its entirety.
  • Private Copyright Assignment Term: by signing and presenting this term, the author(s) assigns and transfers all ownership copyrights regarding the work unto the Brazilian Society of Anesthesiology (SBA), assignee. The author(s) might sign it altogether or several individual copies.

Along with the submission process, authors will be asked to complete the Journal Publishing Agreement.

  • This document includes any tables, illustrations or other material submitted for publication as part of the manuscript, in all forms and media (whether now known or later developed) throughout the world, in all languages, for the full term of copyright, effective when the Article is accepted for publication. An e-mail will be sent to the corresponding author confirming receipt of the submitted manuscript with a ‘Journal Publishing Agreement” form or a link to the online version of this agreement.
