This multicenter trial was conducted at 15 prehospital bases and 5 major trauma centers in Denmark, the Netherlands, and Switzerland. The 30-day follow-up period ended on October 12, 2023. The primary outcome was assessed by medical specialists in anesthesia and intensive care medicine blinded to the randomization.<\/jats:p><\/jats:sec>Interventions<\/jats:title>In the prehospital setting or on trauma center admission, patients were randomly assigned 1:1 to a restrictive oxygen strategy (arterial oxygen saturation target of 94%) (n\u2009=\u2009733) or liberal oxygen strategy (12-15 L of oxygen per minute or fraction of inspired oxygen of 0.6-1.0) (n\u2009=\u2009724) for 8 hours.<\/jats:p><\/jats:sec>Main Outcomes and Measures<\/jats:title>The primary outcome was a composite of death and\/or major respiratory complications within 30 days.

Death and\/or major respiratory complications within 30 days occurred in 118 of 733 patients (16.1%) in the restrictive oxygen group and 121 of 724 patients (16.7%) in the liberal oxygen group (odds ratio, 1.01 [95% CI, 0.75 to 1.37]; P<\/jats:italic>\u2009=\u2009.94; absolute difference, 0.56 percentage points [95% CI, \u22122.70 to 3.82]). No significant differences were found between groups for each component of the composite outcome. Adverse and serious adverse events were similar across groups, with the exception of atelectasis, which was less common in the restrictive oxygen group compared with the liberal oxygen group (27.6% vs 34.7%, respectively).<\/jats:p><\/jats:sec>Conclusions and Relevance<\/jats:title>In adult trauma patients, an early restrictive oxygen strategy compared with a liberal oxygen strategy initiated in the prehospital setting or on trauma center admission for 8 hours did not significantly reduce death and\/or major respiratory complications within 30 days.<\/jats:p><\/jats:sec>Trial Registration<\/jats:title>ClinicalTrials.gov Identifier: NCT05146700<\/jats:ext-link><\/jats:p><\/jats:sec>","DOI":"10.1001\/jama.2024.25786","type":"journal-article","created":{"date-parts":[[2024,12,10]],"date-time":"2024-12-10T22:30:30Z","timestamp":1733869830000},"page":"479","source":"Crossref","is-referenced-by-count":30,"title":["Early Restrictive vs Liberal Oxygen for Trauma Patients"],"prefix":"10.1001","volume":"333","author":[{"given":"Tobias","family":"Arleth","sequence":"first","affiliation":[{"name":"Department of Anesthesia, Center of Head and Orthopedics, Rigshospitalet, Copenhagen, Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Josefine","family":"Baekgaard","sequence":"additional","affiliation":[{"name":"Department of Anesthesia, Center of Head and Orthopedics, Rigshospitalet, Copenhagen, Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Volkert","family":"Siersma","sequence":"additional","affiliation":[{"name":"The Research Unit for General Practice and Section of General Practice, Department of Public Health, University of Copenhagen, Copenhagen, Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andreas","family":"Creutzburg","sequence":"additional","affiliation":[{"name":"Department of Anesthesia, Center of Head and Orthopedics, Rigshospitalet, Copenhagen, Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Felicia","family":"Dinesen","sequence":"additional","affiliation":[{"name":"Department of Anesthesia, Center of Head and Orthopedics, Rigshospitalet, Copenhagen, Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Oscar","family":"Rosenkrantz","sequence":"additional","affiliation":[{"name":"Department of Anesthesia, Center of Head and Orthopedics, Rigshospitalet, Copenhagen, Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Johan","family":"Heiberg","sequence":"additional","affiliation":[{"name":"Department of Anesthesia, Center of Head and Orthopedics, Rigshospitalet, Copenhagen, Denmark"},{"name":"Institute of Clinical Medicine, University of Copenhagen, Copenhagen, Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dan","family":"Isbye","sequence":"additional","affiliation":[{"name":"Department of Anesthesia, Center of Head and Orthopedics, Rigshospitalet, Copenhagen, Denmark"},{"name":"Institute of Clinical Medicine, University of Copenhagen, Copenhagen, Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"S\u00f8ren","family":"Mikkelsen","sequence":"additional","affiliation":[{"name":"The Prehospital Research Unit, Region of Southern Denmark, Odense University Hospital, Odense, Denmark"},{"name":"Department of Anaesthesiology and Intensive Care, Odense University Hospital, Odense, Denmark"},{"name":"Department of Regional Health Research, University of Southern Denmark, Odense, Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Peter M.","family":"Hansen","sequence":"additional","affiliation":[{"name":"The Prehospital Research Unit, Region of Southern Denmark, Odense University Hospital, Odense, Denmark"},{"name":"Department of Anesthesiology and Intensive Care Medicine, Odense University Hospital Svendborg, Svendborg, Denmark"},{"name":"Danish Air Ambulance, Aarhus, Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Stine T.","family":"Zwisler","sequence":"additional","affiliation":[{"name":"The Prehospital Research Unit, Region of Southern Denmark, Odense University Hospital, Odense, Denmark"},{"name":"Department of Anaesthesiology and Intensive Care, Odense University Hospital, Odense, Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"S\u00f8ren","family":"Darling","sequence":"additional","affiliation":[{"name":"Department of Anaesthesiology and Intensive Care, Odense University Hospital, Odense, Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Louise B.","family":"Petersen","sequence":"additional","affiliation":[{"name":"The Prehospital Research Unit, Region of Southern Denmark, Odense University Hospital, Odense, Denmark"},{"name":"Department of Anaesthesiology and Intensive Care, Odense University Hospital, Odense, Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Maria C.
