Haemodynamic-Focused Bedside Ultrasound Enhances Early Detection of Sacral Pressure Injuries in Immobilised Polytrauma Patients.
Article in International wound journal, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Early detection of sacral pressure injuries (PIs) in immobilised polytrauma patients remains challenging. This study evaluated ultrahigh-frequency (UHF) ultrasound combining structural and haemodynamic parameters for early PI diagnosis. In a prospective cohort of 73 polytrauma patients (Injury Severity Score 16-25), daily sacrococcygeal assessments were performed over 15 days using UHF ultrasound (Mindray Resona 11; L20-5 s 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 = 20; all stage I/II). Haemodynamic markers outperformed 2D ultrasound: CPA grade ≥ 1 (AUC = 0.858, 80.0% sensitivity) and PSV > 5.55 cm/s (AUC = 0.841, 95.0% sensitivity). Combined CPA + PSV achieved superior accuracy (AUC = 0.922). Systemic inflammation showed no intergroup differences. UHF ultrasound detects early PIs by capturing ischaemia-reperfusion changes. The CPA + PSV protocol provides nurses with a rapid (< 5 min), sensitive bedside tool to guide proactive interventions.
