This guide provides essential information for authors preparing manuscripts for submission to the journal. Authors are encouraged to read this guide carefully before submission and to consult the journal's Aims and Scope, Article Types, Open Access and Fees, and Journal Policies pages where applicable.
The journal publishes scholarly work in perioperative medicine, including anesthesiology, perioperative care, surgical patient safety, critical care, pain medicine, airway management, perioperative monitoring, enhanced recovery, perioperative inflammation and immunity, perioperative complications, translational perioperative science and related interdisciplinary fields.
The journal accepts manuscripts written in English. Authors are responsible for ensuring that manuscripts are clear, accurate, and suitable for international scholarly communication.
Manuscripts that do not meet the journal's requirements may be returned for correction before editorial assessment or peer review. Submission of a manuscript does not guarantee external peer review or acceptance.
Please review the journal's Aims and Scope to determine whether their work is suitable for the journal.
Authors who are uncertain whether their manuscript is suitable for the journal may contact the Editorial Office with a pre-submission inquiry before submitting.
A pre-submission inquiry should include:
the manuscript title;
the author list;
the abstract; and
a brief explanation of the manuscript's relevance to the journal.
A response to a pre-submission inquiry is advisory only and does not guarantee peer review or acceptance.
The journal considers several types of manuscripts. Authors should select the article type that best matches the purpose, design and scope of their work.
Detailed requirements for each article type, including word limits, abstract format, reference limits, figure and table limits and required sections, are provided on the Article Types page.
Common article types may include:
Research Article
Reports original research findings based on experimental, clinical, translational, epidemiological, public health, methodological or other scholarly research. Original Research Articles should generally include Introduction, Methods, Results and Discussion sections.
Review Article
Provides a comprehensive, balanced and critical overview of a defined topic. Review Articles should synthesize current evidence, identify knowledge gaps and discuss future directions.
Systematic Review and Meta-analysis
Presents a systematic search, selection, appraisal and synthesis of existing evidence. Authors should follow appropriate reporting guidelines, such as PRISMA, and provide protocol registration information where applicable.
Brief Report / Short Communication
Reports concise but significant findings that may not require a full-length article. These submissions should present clear methods, focused results and a well-supported conclusion.
Case Report / Case Series
Describes clinically or scientifically important cases with educational, diagnostic, therapeutic or mechanistic relevance. Written informed consent must be obtained when identifiable patient information is included.
Guideline / Consensus
Provides evidence-based or expert consensus recommendations on a specific topic. The methodology for evidence review, consensus development and recommendation grading should be clearly described.
Editorial / Commentary / Perspective
Presents expert opinion, critical discussion or interpretation of current issues in the field. These article types are usually commissioned, but unsolicited submissions may be considered at the editors’ discretion.
Letter to the Editor
Provides brief comments on articles published in the journal or concise observations of interest to readers.
For formatting examples and full‑text preparation guidelines, authors may refer to the Samples page and review the relevant sample manuscripts prior to submission.
Manuscripts should be prepared clearly, concisely and consistently. Authors should write for an international scholarly audience and avoid unnecessary jargon, unsupported claims or excessive technical detail that is not essential to understanding the work.
File Format
Manuscripts should be submitted in an editable format, such as Microsoft Word. LaTeX files may be accepted where appropriate. Figures, tables and supplementary materials should be prepared according to the journal’s file and formatting requirements.
Title Page
The title page should include:
manuscript title;
full names of all authors;
author affiliations;
corresponding author name, email address and full contact details;
equal contribution or co-corresponding author notes, where applicable;
short running title, if required;
word count, number of figures, number of tables and number of supplementary files, if requested.
Abstract and Keywords
The abstract should accurately summarize the purpose, methods, main findings and conclusions of the manuscript. Original Research Articles and clinical studies should generally use a structured abstract where required by the article type.
Authors should provide keywords that are specific, searchable and relevant to the manuscript. Medical subject headings or other standardized terms may be used where appropriate.
Main Text
Original Research Articles should generally include:
Introduction;
Methods;
Results;
Discussion;
Conclusions, where appropriate.
The Methods section should provide sufficient detail to allow the work to be evaluated and, where applicable, reproduced. Statistical methods, software, study design, participant selection, experimental procedures and analysis plans should be described clearly.
The Results section should present findings in a logical order, supported by appropriate tables, figures and statistical information. The Discussion should interpret the findings in the context of existing evidence, acknowledge limitations and avoid overstating conclusions.
Tables and Figures
Tables and figures should be numbered consecutively in the order in which they are cited in the text. Each table and figure should have a clear title and legend.
Figures should be of sufficient resolution for peer review and publication. Authors should avoid image manipulation that could misrepresent the data. Adjustments to brightness, contrast or color balance must not obscure, eliminate or misrepresent information.
Where figures or tables are reproduced or adapted from another source, authors must obtain appropriate permission and provide proper attribution.
Clinical Images, Videos and Monitoring Data: Clinical images, videos, intraoperative photographs, airway images, ultrasound images, monitoring screen shots, anesthesia records, ICU data or other perioperative materials should be anonymized before submission. Written consent for publication is required when any patient, participant or case detail may be identifiable.
Supplementary Materials
Supplementary materials should be directly relevant to the manuscript and should support, but not replace, the main text. Supplementary files may include extended methods, additional tables, figures, datasets, checklists, protocols, statistical analysis plans, videos, code or other supporting information.
References
References should be accurate, complete and relevant. Authors are responsible for checking all references before submission. References should be formatted in accordance with the journal’s reference style. Please click here to download the journal’s EndNote output style.
Authors should avoid inappropriate citation practices, including excessive self-citation, citation manipulation or citation of unreliable sources.
Language and Style
Manuscripts should be written in clear English. Authors who are not fluent in English may consider professional language editing before submission. Language editing does not guarantee editorial review or acceptance.
Reporting Guidelines and Perioperative Research Requirements
Authors should follow appropriate reporting guidelines according to study design and should submit completed checklists where required.
Relevant guidelines may include:
CONSORT for randomized trials;
SPIRIT for clinical trial protocols;
PRISMA for systematic reviews and meta-analyses;
