Platelet Dysfunction After Traumatic Brain Injury: Beyond Platelet Count 📄 Neurocritical Care | Viewpoint | October 2026 Quintana Diaz & Godoy link.springer.com/article/10… 🔹 Key Insights: • Platelet dysfunction may occur after TBI despite a normal platelet count. • Functional impairment can develop early and is associated with TBI severity, hemorrhagic progression, transfusion requirements, and mortality. • Conventional coagulation tests and platelet counts may fail to detect this dysfunction. • TEG with platelet mapping and other platelet function assays may help identify high-risk phenotypes, but evidence remains limited and assay agreement is poor. • Routine platelet transfusion or desmopressin is not supported by current evidence. 🎯 Take-home message: TBI-associated platelet dysfunction should be viewed as a dynamic hemostatic phenotype rather than simply thrombocytopenia. Prospective phenotype-guided trials are needed. #NeurocriticalCare #TBI #Coagulopathy #NeuroICU

🔎 POCUS in ED sepsis: identifying the source & reassessing physiology This narrative review proposes a pragmatic framework addressing two bedside questions: 📍 Where is the likely infection source? 💧 Will more fluid improve perfusion or worsen congestion? Two complementary approaches: 1️⃣ Source-oriented assessment Targeted scans may identify findings suggesting pneumonia, pleural complications, biliary disease, urinary obstruction, or drainable soft-tissue infection—triggering formal imaging, consultation, and source-control pathways. 2️⃣ Physiologic reassessment 🫀 Focused cardiac ultrasound to characterize hemodynamics. 🔄 PLR + LVOT VTI to assess fluid responsiveness. 🫁 Serial lung ultrasound to monitor pulmonary congestion. 🔵 Venous Doppler/VExUS as optional advanced assessments: ED sepsis-specific evidence remains limited. ⚠️ Diagnostic capability does not establish outcome benefit. Direct evidence that POCUS-guided ED sepsis pathways improve patient-centered outcomes remains limited. 💡 Use targeted, time-limited POCUS to support decisions. It should never delay antimicrobials, definitive imaging, or specialist involvement. 📖 Chen et al. | Frontiers in Medicine | 2026 doi.org/10.3389/fmed.2026.19… #Sepsis #SepticShock #POCUS #EmergencyMedicine #CriticalCare #IntensiveCare #Hemodynamics #FluidResponsiveness #FluidManagement #VExUS #LungUltrasound #SourceControl #MedEd

🫀 The venous dimension of shock: beyond arterial pressure Adequate MAP does not necessarily mean adequate organ perfusion. Elevated venous back-pressure can impair perfusion despite apparently preserved arterial hemodynamics. This narrative review highlights: 🔹 Organ perfusion reflects arterial inflow, venous outflow pressure, and microcirculatory function. 🔹 Venous congestion may contribute to renal, hepatic, splanchnic, cerebral, and right-heart dysfunction. 🔹 POCUS, venous Doppler, and ultrasound-based congestion scores can complement bedside assessment. 🔹 A proposed phenotype-based approach integrates arterial pressure, forward flow, venous congestion, and tissue perfusion. 💡 Persistent hypoperfusion warrants assessment of both inflow and outflow, alongside the microcirculation. 📖 Kataria et al. | World J Crit Care Med | 2026 doi.org/10.5492/wjccm.122632 #CriticalCare #IntensiveCare #ICU #Hemodynamics #Shock #VenousCongestion #POCUS #VExUS #Ultrasound #OrganPerfusion #Microcirculation #FluidManagement #Resuscitation #CardiorenalSyndrome #MedEd
