Manuscript Preparation

All manuscripts should be submitted via the journal’s online submission and review system; do not submit a manuscript via e-mail. Make sure your submission is complete and correct before completing the steps to submit it to the journal office. Manuscripts that do not satisfy minimum submission requirements will be returned to authors to correct. You will have an opportunity to review the constructed PDF file before approving the submission. Review this document carefully; after it is sent to the editors and reviewers, no changes can be made until an editorial decision is reached.

All submissions require a Title Page. Manuscripts must be double-spaced. Fonts should be 10 point or larger. All four margins should be at least 2.5 cm (1 in). If a manuscript is formatted for A4 paper, leave at least a 5 cm (2 in) margin at the bottom of the page. Number pages consecutively, preferably the upper right corners.

At first submission, manuscripts may be submitted as single Word document files, including title page, references, figure legends, figures, and tables. All manuscript components need to be included to allow for evaluation of your manuscript. If the editors request a revision, however, source files of the manuscript, figures, and tables will be required as well as other submission and publication elements.

The structured abstract should contain four labeled paragraphs: Background, Methods, Results, and Conclusions.  The Abstract may be the only part of an article that is read, and must stand alone and effectively convey the key elements within an article. Please ensure that the Abstract communicates the research context, purpose and a hypothesis; the key methods, the most important findings (including the primary outcome, at minimum) described using numerical results (and statistical significance(, and clear conclusions which are supported by those results. An Abstract with narrative results and p values is not acceptable. Please ensure that any data in the Abstract are also in the main Results. In order to enhance comprehension, the use of nonstandard abbreviations or acronyms in the Abstract is not allowed. Refer to the List of Standard Abbreviations.

    Review Articles and Special Articles require an unstructured, one- or two-paragraph summary of the key points of the article of 150 words or fewer.

  • Body Text
    1. Introduction (new page, 500-word limit;
    2. Materials and Methods (new page): A subsection entitled "Statistical Analysis" should appear at the end of the Materials and Methods section when appropriate (for comments re. Statistics). Include, as relevant, statements about informed consent, animal care, IRB approval, and/or clinical trial registration;
    3. Results (new page);
    4. Discussion (new page, 1,500-word limit): The discussion should focus on the findings in the current work.
    LENGTH: The Introduction and Discussion sections should not exceed 2,000 words combined. It is recommended that the Introduction be no longer than 500 words and the Discussion section no more than 1,500 words. Manuscripts that do not meet these word limits may be sent back to the authors.
    PAGE NUMBERING: Number all pages in the manuscript file.

  • References Number references (as superscripts) in the sequence they appear in the text. Use abbreviated titles of the medical journals as they appear in Index Medicus. Include only references accessible to all readers. Do not include articles published without peer review or material appearing in programs of meetings or in organizational publications. Sites on the World Wide Web (URLs) may be used as references, provided the citation includes the last accessed date. Abstracts are acceptable as references only if published within the previous 3 years. Manuscripts in preparation or submitted for publication are never acceptable as references. If you cite accepted manuscripts "In Press" as references, please provide one electronic copy (e.g., Word, PDF) when you submit the new manuscript and mark them as "In Press, Reference # ___."
    Supply all authors' names for each reference; do not use "et al." Please confirm the accuracy of your references by comparison with original sources, not with someone else's reference lists, and examine your citations for typographical errors. Supply complete publication information for all references.
    Anesthesiology style is that references in legends to tables and figures be cited in the order in which they occur (as if they were cited in the text). This includes references that appear only in a table or figure legend and not in the text. Because it is recognized that authors may use software to format references, and to ensure that references are cited in the proper order, references cited in a table or figure legend should also be cited in the text at the first (but not necessarily subsequent) callout to that figure or table; a reference should not be cited only in a table or figure legend. If references are cited only in a table or figure legend, this will require renumbering of references during composition of the manuscript and possibly delay publication.
    Use the following reference formats:
    1. Journal: Carli F, Mayo N, Klubien K, Schricker T, Trudel J, Belliveau P: Epidural analgesia enhances functional exercise capacity and health-related quality of life after colonic surgery: Results of a randomized trial. Anesthesiology 2002; 97:540-9
    2. Book: Barash PG, Cullen BF, Stoelting RK: Clinical Anesthesia, 3rd edition. Philadelphia, Lippincott-Raven Publishers, 1997, pp 23-4
    3. Chapter: Blitt C: Monitoring the anesthetized patient, Clinical Anesthesia, 3rd edition. Edited by Barash PG, Cullen BF, Stoelting RK. Philadelphia, Lippincott-Raven Publishers, 1997, pp 563-85

  • Tables Number tables consecutively in order of appearance (Table 1, etc.). Make sure tables are cited/called-out in the text in the correct order. Each Table should be submitted as a separate file. Each table must have a title and include footnotes when appropriate. Make sure any symbols and abbreviations used in the tables are defined. Tables must be word processing document format (eg, .doc). Do not submit tables as image files.
  • Back to top

  • Appendices Upload each appendix as a separate file. Number each appendix. Each appendix must be cited within the text, in consecutive order.
  • Back to top

  • Figure Legends Supply a legend/caption for each figure, preferably on the last page of the manuscript file. For review purposes, figures and their accompanying legends can be included as a group at the end of the manuscript file. If a revision is requested, authors will be asked to supply figures as separate original source files with textual legends/captions grouped on a single page in the manuscript file.
  • Back to top

  • Figures Figures should be prepared according to the professional standards of this Journal in appropriate file format with sufficient resolution for publication. If a single figure contains more than one panel, each panel must be identified alphabetically (e.g., A, B, etc.) and should read left to right in presentation. The figures must be cited in the text in the same, consecutive numeric order. Each Figure should be submitted as a separate file, clearly labeled with the figure number (e.g., Figure1.tif, Figure2.eps, etc.).   Make sure that any special symbols used in a figure (e.g., asterisk, double asterisk) are explained in the legend/caption.

    Format: Acceptable graphics formats are .tif, .eps, .jpg, or .pdf.

    Resolution: Photographic or halftone figures should be saved at 300 ppi resolution, with image sizes no smaller than 4 x 6 inches, approximately 1200 to 1800 pixels wide. Line-art, graphs, charts, diagrams must be 1200 ppi, approximately 4800 pixels wide, minimum.

    If images are submitted with resolutions lower than these specifications, we may be unable to publish them, even if we accept the submission. Therefore, please make sure that the images submitted with your manuscript comply with these specifications.

    Additional detailed information about digital art for publication can be found at http://links.lww.com/ES/A42

    If a revision is requested, do not paste graphics into word processing documents; submit them as separate files in figure file format. NOTE: Before approving your submission, view the PDF that is created by the system to make sure images are easily legible for the editors and reviewers.

  • Manuscripts "In Press" Please submit an electronic copy (Word, PDF) of any "In Press" manuscript that is cited in the reference list, labeled as "In Press, Reference # ___." (If a manuscript is not yet In Press, it must be removed from the reference list.)
  • Back to top

  • Supplemental Digital Content Authors may submit Supplemental Digital Content to enhance their article's text and to be considered for online-only posting. Supplemental Digital Content may include the following types of material: text documents, graphs, tables, figures, audio, and video.

    If a manuscript is accepted for publication, authors of Original Investigations, Comprehensive Reviews, and Clinical Focus Reviews can elect to have included in the online (only) version of their article a brief biographical sketch and photos of the first author (and if more than one author) the senior or corresponding author. These biographical sketches and photo files must be uploaded as supplemental digital content in Editorial Manager at the revision stage. The biographical sketch for each author has a limit of 100 words. The photo is limited to a headshot only. Only two authors will be shown. Submission of bio and photo at the revision stage is no guarantee of eventual manuscript acceptance. Manuscripts will not be held in production after acceptance in order for authors to upload bio and photos.

    Number and cite all Supplemental Digital Content consecutively in the text. In-manuscript citations (other than biographical sketches) should include the type of material submitted, should be clearly labeled as "Supplemental Digital Content," should include a sequential number, and should provide a brief description of the supplemental content. For example: “See table, Supplemental Digital Content 1, listing all medications used in this study.” Each Supplemental Digital Content file must be composed to stand alone. For example, tables and figures must include titles, legends, and/or footnotes, following journal style, so the viewer can fully understand the supplemental content on its own. Production will not make any edits to the supplemental files; they will be presented as submitted.

    For audio and video files, enter the author name, videographer, participants, length (minutes), and size (MB) of file in Editorial Manager. Authors should de-identify patients and remove patients’ names from Supplemental Digital Content,  obtain written consent from the patients or legal guardians, and submit written consent with the manuscript. Copyright for video or audio supplemental digital content will be required upon acceptance. For a list of acceptable file types and size limits, please review the publisher’s requirements for submitting Supplemental Digital Content.

  • Units of Measurement Use metric units. The units for pressures are mmHg or cmH2O. Diagonal slashes are acceptable for simple units, e.g., mg/kg; when more than two items are present, negative exponents should be used, i.e., ml · kg-1 · min-1 instead of ml/kg/min.
  • Back to top

  • Drug Names and Equipment Use generic names. If a brand name must be used, insert it in parentheses after the generic name. Provide manufacturer's name, city, state, and country. Be careful about the use of trademarked terms (e.g., ThrombelastographyTM, TEGTM, etc.).
  • Back to top

  • Data Reporting and Statistics Detailed statistical methodology must be reported.  Describe randomization procedures and the specific tests used to examine each part of the results; do not simply list a series of tests.  Care should be taken with respect to:  a) reporting of parametric vs. nonparametric data (median range (or percentiles) is preferred for nonparametric data); b) parametric vs. nonparametric statistical methods; c) corrections for multiple comparisons; d) false precision (summary statistics should not contain more significant digits or decimal places than the original data); and e) variance reporting (standard deviation or 95% confidence interval, rather than standard error of the mean).
  • Back to top

  • Patient Identification Do not use patients' names, initials, or hospital numbers. An individual (other than an author) must not be recognizable in photographs unless written consent of the patient or legal guardian has been obtained and is provided at the time of submission. Authors should obtain consent forms from the relevant institution(s).
  • Back to top

  • Sources of Compounds Sources of compounds, reagents, and equipment should be identified by name and affiliation. Refer to drugs by their generic or chemical name, without abbreviation. Use a code number only when a generic name is not yet available. The identity and structure of novel research compounds, chemicals, and biologics must be cited, or provided if not previously published. Report the source of cell lines, and, if known, their authentication and mycoplasma contamination status.
