Adverse events, particularly sepsis, should be minimized. We aimed to identify sex-specific predictors for sepsis in polytrauma patients undergoing stand-alone definitive surgery. Materials and Methods: Our institutional trauma database, containing data from 3653 patients between 1996 and 2022, was filtered for polytrauma patients who underwent definitive surgery, were aged \u226516 years, and had an Injury Severity Score (ISS) \u226516. Injury and physiological parameters were documented upon admission, as well as on the first and second days thereafter. Surgical data were also recorded. All factors were evaluated for their association with sepsis development. Results: Among the 276 patients (71.1% male; mean age 45.0 years, 95% confidence interval 42.7\u201347.2 years; median ISS of 27, interquartile range, 20\u201334), the rate of sepsis was 13.8% (n = 38), with a higher incidence in males (16.7%; n = 33) than in females (6.8%; n = 5) (p = 0.026). Head and thorax injuries were more common and severe in septic males, with thorax injuries being predictive. Male patients who developed sepsis also had a higher ISS, an increased heart rate (HR), and lower pH at admission, with ISS and HR being predictive of sepsis. On the first day post-admission, septic males showed higher Base Excess and lower Prothrombin Time. Lactate levels were elevated on both the first and second days post-admission. Surgical predictors for males included less primary extremity surgeries and later secondary spine surgeries. Conclusions: Sepsis is more common in males undergoing stand-alone definitive surgery. Several factors, particularly acidosis and coagulopathy, are associated with this phenomenon. Fewer primary extremity surgeries and delayed secondary spine surgeries were also linked to a higher sepsis risk in males. These findings may help identify patients eligible for stand-alone definitive surgery and underscore the need for more data on female polytrauma patients.<\/jats:p>","DOI":"10.3390\/medicina61020183","type":"journal-article","created":{"date-parts":[[2025,1,22]],"date-time":"2025-01-22T03:40:17Z","timestamp":1737517217000},"page":"183","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Sex-Specific Differences in Sepsis Development in Polytrauma Patients Undergoing Stand-Alone Definitive Surgery"],"prefix":"10.3390","volume":"61","author":[{"given":"Philipp","family":"Vetter","sequence":"first","affiliation":[{"name":"Department of Trauma Surgery, University Hospital Zurich, 8091 Zurich, Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"C\u00e9dric","family":"Niggli","sequence":"additional","affiliation":[{"name":"Department of Trauma Surgery, University Hospital Zurich, 8091 Zurich, Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jan","family":"Hambrecht","sequence":"additional","affiliation":[{"name":"Department of Trauma Surgery, University Hospital Zurich, 8091 Zurich, Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hans-Christoph","family":"Pape","sequence":"additional","affiliation":[{"name":"Department of Trauma Surgery, University Hospital Zurich, 8091 Zurich, Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7246-1266","authenticated-orcid":false,"given":"Ladislav","family":"Mica","sequence":"additional","affiliation":[{"name":"Department of Trauma Surgery, University Hospital Zurich, 8091 Zurich, Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,1,22]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Joestl, J., Lang, N.W., Kleine, A., Platzer, P., and Aldrian, S.
