This study evaluated ultrahigh\u2010frequency (UHF) ultrasound combining structural and haemodynamic parameters for early PI diagnosis. In a prospective cohort of 73 polytrauma patients (Injury Severity Score 16\u201325), daily sacrococcygeal assessments were performed over 15\u2009days using UHF ultrasound (Mindray Resona 11; L20\u20105\u2009s probe). Parameters included 2D morphology, perfusion (colour power angiography [CPA]), flow metrics (peak systolic velocity [PSV]), Braden Scale and inflammatory markers. PI incidence was 27.4% (\n                    <jats:italic>n<\/jats:italic>\n                    \u2009=\u200920; all stage I\/II). Haemodynamic markers outperformed 2D ultrasound: CPA grade \u2265\u20091 (AUC\u2009=\u20090.858, 80.0% sensitivity) and PSV &gt;\u20095.55\u2009cm\/s (AUC\u2009=\u20090.841, 95.0% sensitivity). Combined CPA\u2009+\u2009PSV achieved superior accuracy (AUC\u2009=\u20090.922). Systemic inflammation showed no intergroup differences. UHF ultrasound detects early PIs by capturing ischaemia\u2010reperfusion changes. The CPA\u2009+\u2009PSV protocol provides nurses with a rapid (&lt;\u20095\u2009min), sensitive bedside tool to guide proactive interventions.\n                  <\/jats:p>","DOI":"10.1111\/iwj.70966","type":"journal-article","created":{"date-parts":[[2026,6,5]],"date-time":"2026-06-05T00:33:56Z","timestamp":1780619636000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Haemodynamic\u2010Focused Bedside Ultrasound Enhances Early Detection of Sacral Pressure Injuries in Immobilised Polytrauma Patients"],"prefix":"10.1111","volume":"23","author":[{"given":"Jing","family":"Chen","sequence":"first","affiliation":[{"name":"Ultrasonography Department of Chongqing Emergency Medical Center  Chongqing China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yi","family":"diWen","sequence":"additional","affiliation":[{"name":"Ultrasonography Department of Chongqing Emergency Medical Center  Chongqing China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dongxu","family":"Zhu","sequence":"additional","affiliation":[{"name":"Ultrasonography Department of Chongqing Emergency Medical Center  Chongqing China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yan","family":"Du","sequence":"additional","affiliation":[{"name":"Ultrasonography Department of Chongqing Emergency Medical Center  Chongqing China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Luo","family":"Yuan","sequence":"additional","affiliation":[{"name":"Department of Cardiothoracic Surgery of Chongqing Emergency Medical Center  Chongqing China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,6,4]]},"reference":[{"key":"e_1_2_9_2_1","doi-asserted-by":"publisher","DOI":"10.1097\/WON.0000000000000906"},{"issue":"10","key":"e_1_2_9_3_1","first-page":"865","article-title":"Development and Controversy of the Definition of Multiple Injury","volume":"38","author":"Li H.","year":"2022","journal-title":"Chinese Journal of Traumatology"},{"key":"e_1_2_9_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.iccn.2020.102924"},{"issue":"6","key":"e_1_2_9_5_1","first-page":"390","article-title":"Economic Evaluation of Pressure Ulcer Care: A Cost Minimization Analysis of Preventive Strategies","volume":"27","author":"Schuurman J.
