The editors of Anesthesiology are pleased to publish articles online ahead of print. Starting in 2022, Original Investigation articles will initially appear in a pre-proof format using the accepted version of the manuscript. The pre-proof will be replaced by the final version of the article that has been been copyedited, proofread, typeset, and reviewed by the author(s) but has not appeared in an issue of the journal. Each article published online ahead of print is citable in pre-proof or final version. The pre-proof cover sheet will note the citation text. Anesthesiology articles are assigned Digital Object Identifiers (DOIs), providing a persistent, permanent way to identify articles published in the online environment. Other article types will be posted Online First only when the final copyedited and approved version is available.
