Shock with a shattered ring — bind, transfuse, pack the venous bleed, plug the blush on a clock

Examiner route

• Opening (binder + blood): the candidate must bind immediately — ATLS standard yet delivered to only 47% of unstable fractures — with simultaneous blood and products inside an algorithmic pathway of the kind that cut mortality from 20% to 7.7%.^[14][15]
• Bleeding logic: venous and bony bleeding is the majority, so packing is the unstable-despite-red-cells operation; embolisation remains the arterial mainstay — and with 90 minutes to the suite against a ready theatre, the candidate must pack now and plan embolisation for the blush, since a quarter of packed patients need subsequent embolisation anyway.^[12][5][7]
• Clock pressure: the candidate must quote the timing curve — 0% dead at 0 to 30 minutes rising to 17.0% adjusted at 150 to 180 — and the system confession that median time to angiography runs 286 minutes, to justify transfer and parallel-preparation decisions.^[4][5]
• REBOA fence: EAST shows no overall benefit with a pelvic harm signal (OR 2.15), so the candidate may offer it only as a bridge to packing, never as the plan.^[3]
• Urology sequencing: blood at the meatus with an unstable ring means retrograde urethrogram before any catheter — LUTI incidence 7.7%, confined to unstable patterns.^[21]
• Counsel and age: Tile C vertical shear with shock carries 58% mortality (19% overall, 42% with shock); management stays physio-plus-anatomy per WSES; at 58, transfusion need is 2.8-fold with higher death at the same ISS, so thresholds drop.^[23][1][17]

Pass standard

Binds before imaging, packs the unstable now rather than waiting 90 minutes, embolises the blush on a clock, fences REBOA honestly, images the urethra before catheterising, counsels Tile C shock at 58%, and adjusts for age with the transfusion multiplier.^{[14][12][4][3][21][23][17]}
