Acta Anaesthesiologica Scandinavica publishes original work in the fields of anaesthesiology, intensive care, pain, and emergency medicine. This includes clinical or laboratory investigations, review articles, case reports and letters to the Editor.

Manuscripts will be reviewed on the understanding that they have not been published, simultaneously submitted or accepted for publication elsewhere. It is expected that the work presented has been performed in accordance with the most recent version of the Helsinki Declaration and it should be stated in the manuscript that necessary permission has been obtained from the appropriate ethics committee. The following information must be reported: the name and address of the ethics committee responsible; the protocol number that was attributed by this ethics committee and the date of approval by the ethics committee.

Approvals from other relevant, national bodies must also be declared. The Editorial Board may exercise judgment about the ethics of a clinical trial involving investigational drugs that is more stringent than the investigator’s ethics committee, especially in studies of drugs in children and if the dose, route of administration, and indication do not match the guidelines in the package insert (“off-label”), for instance related to neuraxial administration. Reports of investigations in animals will not be accepted for publication unless the text states that the study was approved by the appropriate animal investigation committee.

Registration of Clinical Trials
This is relevant for clinical trials if patient enrolment began after January 1, 2010. Research is considered to be a clinical trial if it involves prospective assignment of human subjects to an intervention or comparison group to study the relation between a health-related intervention and a health outcome. Trials must be registered before recruitment of the first subject in a public trials registry that can be assessed by the editors, the reviewers, and the readers.

The registry must be accessible to the public at no charge, searchable, open to all prospective registrants, and managed by a not-for-profit organization. The registry must include the following information: a unique identifying number, a statement of the intervention(s), study hypothesis, definition of primary and secondary outcome measurements, eligibility criteria, target number of subjects, funding source, contact information for the principal investigator, and key dates (registration date, start date, and completion date). The following registries are recommended: Clinical Trials, ISRCTN Register, UMIN Clinical Trials Registry, Australia New Zealand Clinical Trials Registry, Nederlands Trial Register.

Authors are requested to provide the exact URL and unique identification number for the trial registration at the time of submission. This information will be published in the article and we ask that you include the URL and identification number on the title page of your manuscript.

Acta Anaesthesiologica Scandinavica employs a plagiarism detection system. By submitting your manuscript to this journal you accept that your manuscript may be screened for plagiarism against previously published works.

Pre-submission English Language Editing Service

Authors for whom English is a second language may choose to have their manuscript professionally edited before submission. The English Language Editing Service can help to ensure your paper is clearly written in standard, scientific English language appropriate to your discipline. Visit Wiley English Language Editing Service to learn about the different options. All services are paid for and arranged by the author, and use of one of these services does not guarantee acceptance or preference for publication.

Patient Consent Form
Images of, or information about, identifiable individuals: It is the author’s responsibility to obtain consent from patients and other individuals for use of information, images, audio files, interview transcripts, and video clips from which they may be identified. To ensure we have the rights, we require a signed consent/release form in all instances. Please find the form here. If the person is a minor, consent must be obtained from the child’s parents or guardians.  

  • If the person is a minor, consent must be obtained from the child’s parents or guardians
  • If the person is dead, we consider it essential and ethical that you obtain consent for use from the next of kin. If this is impractical you need to balance the need to use the photo against the risk of causing offence. In all cases ensure you obscure the identity of the deceased.
  • If using older material, or for material obtained in the field, for which signed release forms are, for practical purposes, unobtainable, you will need to confirm in writing that the material in question was obtained with the person’s understanding that it might be published.

Submission form
All submissions must include a completed Submission Form that has been signed by all authors. If you do not provide this form your manuscript will not be sent for review. Please upload a scan of the completed and signed form as a 'supplemental file not for review' when submitting your manuscript.

Manuscript preparation
Manuscripts should be prepared and submitted in accordance with: 'Uniform requirements for manuscripts submitted to biomedical journals' (  We recommend authors to have a look at a recent issue concerning abbreviations, units, figures, and tables.

Manuscripts should normally not exceed 3000 words (excl. abstract, tables, figures, and references), and should be divided into the following sections:

  1. The title page (pg. 1) with a short and informative title (preferably less than 15 words and please avoid abbreviations in the title), the names of the authors (first name, initials (if any) and last name, no titles), the name and location of the institutions where the work was carried out, a short title of no more than 40 letters and spaces, a word count (excl. abstract and references) and the name, jobtitle and address (including tel., fax. and e-mail address) of the author to whom correspondence should be addressed. Any relevant conflict of interest must be described in the manuscript in a footnote on the title page.
  2. Abstract (on a separate page (page 2). The abstract must not exceed 250 words. Abstracts should be structured as follows: background, methods, results and conclusion. Each part of the abstract should start on a new line. Abbreviations should normally not be used in the abstract.
  3. Introduction starts on the third page. In all manuscripts reporting original research, a specific hypothesis or research question and aim of study should be clearly stated at the end of this section.
  4. Methods section starts with a new page. Reports of randomised trials must conform to the CONSORT guidelines. For such studies, a flow diagram should be a part of the manuscript and a completed Consort Checklist must be submitted with the manuscript (can be downloaded from the journal homepage). For other types of studies, the CONSORT checklist is also very useful to consult. Primary and possible secondary outcome measures must be thoroughly defined, including how and when they were assessed. Detailed statistical methodology must be reported. Describe the specific tests used to examine the primary outcome measure and also the methods for additional analyses such as subgroup analyses and multiple comparisons. Variability should be expressed either as median with range (or percentiles) for nonparametric data, or mean with standard deviation for normally distributed data. Proportions should be reported with 95% confidence interval. A sample size calculation based on the primary outcome with description of statistical power is required. It must be described how the authors determined the clinically relevant difference to be detected.
  5. Results section should start with a new page. Results related to the primary outcome must be quantified, whether statistically significant or not. This can, as an example, be accomplished by reporting differences with 95% confidence interval.
  6. Discussion section starts with a new page and describes strengths and limitations of the study, interpretation of results, and relation to current evidence. The section should summarise the most important finding in the first paragraph and a conclusion at the end.
  7. Acknowledgements. Individuals thanked must accept this in a signed statement that should be sent with the covering letter. All funding must be reported in the acknowledgements section, even if only to say “Departmental funding only”. An explicit statement is needed in all manuscripts regarding author conflict of interest, even if only to say “The authors have no conflicts of interest”.
  8. References. Start the reference list with a new page. Keep the number of references low. Number references consecutively in the order in which they are first mentioned in the text. Identify references in text, tables, and legends by numbers in superscript. Restrict references to articles published in Index Medicus journals. All author names must be listed. The titles of journals must be abbreviated according to the style used in Index Medicus.

Please note that docx files are compatible with the journal submission systems.

Clinical Practice Guidelines
More than one group or society can issue clinical practice recomendation statements on the same topic. To minimize confusion and to enhance transparency, this type of manuscript submission should begin with the following (below) bulleted phrases, followed by brief comments addressing each phrase. These will be used to generate a general comment box/text to which the editorial board will also contribute, and which will come before the introduction. This box will have a title: Editorial comment, but the authors need to provide adequate responses to the bullet points (and will review the final comment). In this way, these points do not need to be repeated in the Introduction section.

  • What other guideline statements are available on this topic?
  • Why was this guideline developed?
  • How does this statement differ from existing guidelines?
  • Why does this statement differ from existing guidelines?

In the manuscript, the following are required:

  1. Outline of the clinical research question
  2. Formulation of PICOs (Population, Intervention, Comparator, Outcomes)
  3. Systematic search for literature
  4. Generation of an estimate of the effect for each outcome (patient-important outcomes exclusively)
  5. Assessment of the quality of evidence using Grading of the quality of evidence according to the Grading of Recommendations Assessment, Development and Evaluation (GRADE): or equivalent system
  6. Recommendations according to GRADE, or equivalent system
  7. Preparation of summary of findings tables, e.g. using GradePro: or equivalent system
  8. Management of conflicts of interest on a recommendation per recommendation basis

Case Reports
We publish few case reports, typically exceptional cases that we can learn from. A case report manuscript should contain a maximum of 1,000 words, no abstract, and less than 10 references. Case reports will not have an Editorial comment. Please note that there is a risk of violating patient privacy and the author must obtain permission from the patient or the relatives.

Letters to The Editor
Must be submitted as such and will be considered for publication. Letters should encourage scientific discussion on topics pertaining to anaesthesiology and intensive care, pain and emergency medicine. They may contain 1 table or 1 figure and should not exceed 500 words. The editors reserve the right to edit letters for clarity and brevity.

PhD Dissertation Abstract
General information and abstracts regarding recently approved and published Scandinavian medical or PhD dissertations in Anesthesiology and Intensive Care and related topics are continuously published in Acta Anaesthesiologica Scandinavica to promote dissemination of new research results. Please submit a Word file including information in the following order: title of the dissertation; name of Respondent (PhD degree conferee), the degree-confering university and department/section; main supervisor with academic affiliation; co-supervisor(s) if any, with academic affiliation; date of defense; name(s) of Opponent(s) with academic affiliation; original English abstract of the dissertation; and finally a ’reference' list of the individual papers which were part of the thesis including unpublished manuscripts which the dissertation is based on. The list should have the same layout as described above under References. The maximum word count should not exceed 600 words.

This type of article is aiming at publishing justified considerations of contemporary clinical, scientific, or professional policy issues. Language All papers will be published in English and must conform to accepted standards of English style and usage. British or American spelling may be used, but the same spelling should be used throughout the article.

Abbreviations and symbols
Extensive use of abbreviations is discouraged and should be avoided in the title and in the abstract. Use only standardized terms which have been generally accepted. Any unfamiliar abbreviation must be defined when first used. Acta Anaesthesiologica Scandinavica uses 'Units, symbols, and abbreviations. A guide for biological and medical editors and authors', 1988, The Royal Society of Medicine, 1 Wimpole Street, London. With regard to drugs, generic names should normally be used instead of registered trademarks.

Chemical, physical, and clinical units should always be strictly defined. Units of measurement should be expressed and written in accordance with the Système Internationale d'Unités (SI-units), except for blood pressure (expressed as mmHg), drug concentrations, or airway pressure (expressed as cm H20).

Number all figures (graphs, charts and photographs) in the order of their citation in the text. Figures should have titles and these should be written so that the general meaning of each illustration can be understood without reference to the text. Recognisable photographs of patients should be avoided.

It is the policy of Acta Anaesthesiologica Scandinavica for authors to pay the extra cost for the printing of colour illustrations in the print version. In the event that an author is not able to cover the costs of reproducing colour figures in colour in the printed version of the journal Acta Anaesthesiologica Scandinavica offers authors the opportunity to reproduce colour figures in colour for free in the online version of the article (but they will still appear in black and white in the print version). If an author wishes to take advantage of this free colour-on-the-web service, they should liaise with the Editorial Office to ensure that the appropriate documentation is completed for the Publisher. Therefore, please note that if there are colour illustrations in your manuscript, Wiley-Blackwell require you to complete and return a colour work agreement form before your paper can be published. If you are unable to download the form, please contact our Editorial Assistant above. Once completed, please return the form to the address indicated in the form.

Please note that if the manuscript contains colour illustrations, a Colour Work Agreement Form should also be submitted.
Any article received by Wiley with colour work will not be published until the form has been returned. Only the original hardcopy colourwork agreement form can be accepted. Please do not email or fax completed forms.

Tables should be used to clarify important points and to present numerical data that are necessary for the understanding of the results. Avoid unnecessary double presentation of results (in figures and tables). The table should have a title including the table number and a meaningful indication of the table content. Tables may also have an explanatory footnote if necessary. Please indicate in the margin of the manuscript approximately where the tables and figures should be presented.

The corresponding author will receive an e-mail alert containing a link to a web site. A working e-mail address must therefore be provided for the corresponding author. The proof can be downloaded as a PDF (portable document format) file from this site. Acrobat Reader will be required in order to read this file. This software can be downloaded (free of charge) from the following web site: This will enable the file to be opened, read on screen and printed out in order for any corrections to be added. Further instructions will be sent with the proof. Excessive changes made by the author in the proof, excluding typesetting errors, will be charged separately. Proofs must be returned to the publisher within 3 days.

Offprints Free access to the final pdf offprint of your article will be available via author services only. Please therefore sign up for author services if you would like to access your article PDF offprint and enjoy the many other benefits the service offers. Offprints may be ordered on the offprint order form which will accompany the proofs.

Acta Anaesthesiologica Scandinavica is covered by Wiley's EarlyView service. EarlyView articles are complete full-text articles published online in advance of their publication in a printed issue. Articles are therefore available as soon as they are ready, rather than having to wait for the next scheduled print issue. Early View articles are complete and final. They have been fully reviewed, revised and edited for publication, and the authors' final corrections have been incorporated. Because they are in final form, no changes can be made after online publication. The nature of Early View articles means that they do not yet have volume, issue or page numbers, so Early View articles cannot be cited in the traditional way. They are therefore given a Digital Object Identifier (DOI), which allows the article to be cited and tracked before it is allocated to an issue. After print publication, the DOI remains valid and can continue to be used to cite and access the article.

Online production tracking is available for your article through Wiley's Author Services
Author Services enables authors to track their article - once it has been accepted - through the production process to publication online and in print. Authors can check the status of their articles online and choose to receive automated e-mails at key stages of production. The author will receive an e-mail with a unique link that enables them to register and have their article automatically added to the system. Please ensure that a complete e-mail address is provided when submitting the manuscript. Visit for more details on online production tracking and for a wealth of resources including FAQs and tips on article preparation, submission and more.

Author material archive policy: Please note that unless specifically requested, Wiley will dispose of all hardcopy or electronic material submitted two months after publication. If you require the return of any material submitted, please inform the editorial office or production editor as soon as possible if you have not yet done so.
