Prehospital pulse pressure flags trauma bleeding

Injury · Cohort · Hypothesis-generating

A retrospective study of 2,177 adult trauma patients across three Canadian level 1 trauma centres found prehospital pulse pressure predicted active haemorrhage (AUC 0.73), with each 10 mmHg narrowing raising the odds by 51% and a cut-off of ≤45 mmHg most useful for ruling bleeding out.
ECPR timing in refractory OHCA: survival gap persists

European Heart Journal. Acute Cardiovascular Care · Registry · Hypothesis-generating

A target trial emulation in 58,668 patients with refractory OHCA from the Korean nationwide registry found ECPR was associated with higher 30-day survival at 15, 30 and 60 minutes after ED arrival (+15.0, +14.4 and +7.7 percentage points); an exploratory analysis found the benefit narrowed but remained significant to 120 minutes.
Instrumented manikin neck for immobilisation training

Proceedings of the Institution of Mechanical Engineers. Part H, Journal of Engineering in Medicine · Simulation · Context only

Australian engineers built and tested a proof-of-concept instrumented manikin neck with six-degree-of-freedom motion and real-time head-position feedback for immobilisation training, achieving angle measurement error under 0.89° versus motion capture.
