Diagnosis and management of blunt cerebrovascular injuries: A Western Trauma Association critical decisions algorithm
The Western Trauma Association issued an updated critical-decisions algorithm for blunt cerebrovascular injury, giving a practical pathway for screening, imaging, and antithrombotic management of these often-occult carotid/vertebral artery injuries.
Survival benefit of prehospital TXA in fibrinolytic shutdown: Insights from two prospective trauma trials
Pooling 1,249 patients from two prehospital TXA trials and stratifying by TEG LY30, trauma patients in fibrinolytic shutdown who were randomized to TXA had a markedly lower risk of death (HR 0.32), while hyperfibrinolysis independently tripled mortality risk. Supports fibrinolysis profiling to target who benefits most from early TXA.
Diagnostic accuracy of shock index, revised trauma score, and injury severity score for mortality prediction in trauma: A hierarchical meta-analysis
Across 12 studies (234,129 patients), RTS and ISS performed similarly for predicting trauma mortality (AUC ~0.85) and did not differ in a formal paired comparison, while the simpler Shock Index was weaker (AUC 0.75); none reliably rules death in or out alone. The authors argue SI/RTS (acute triage) and ISS (later anatomical benchmark) are complementary roles, not competing scores to rank.
Early multimodal vasopressor strategy in septic shock: results of the TRICYCLE randomized controlled trial
In this 79-patient phase II RCT, starting angiotensin II, vasopressin, and norepinephrine together early in septic shock sped the fall in renin and lactate, lowered 72-h SOFA, and sharply cut tachyarrhythmias (15.6% vs 68.6%) versus stepwise escalation — promising physiology that was not powered to show a mortality benefit.
Impact of Cardiac Rhythm Dynamics during Cardiopulmonary Resuscitation on Clinical Outcomes in Patients Treated with Extracorporeal Cardiopulmonary Resuscitation (ECPR): A Systematic Review and Meta-analysis
Pooling 10 observational studies (5,183 ECPR patients), rhythm improvement (non-shockable to shockable) during CPR roughly tripled the odds of good neurological recovery (RR 3.12), while decay toward asystole strongly predicted failure (RR 0.20). Argues the rhythm trend during resuscitation, not just the initial rhythm, should inform ECPR candidacy.
Palliative and end-of-life care on the battlefield: a scoping review
This scoping review found battlefield pain management (morphine, oral transmucosal fentanyl citrate, ketamine, regional anesthesia) is well documented, but palliative and end-of-life care for expectant/dying combatants remains sparse and largely extrapolated from civilian data, with little training or doctrinal guidance — a widening gap as large-scale combat operations make non-survivable injuries more likely.
Automated External Defibrillators for In-Hospital Cardiac Arrest: A Systematic Review
Across six heterogeneous observational reports, ward-level AED capability before the code team arrives did not consistently improve survival or neurological outcomes in in-hospital cardiac arrest (largest multicentre cohort adjusted RR 1.01). Evidence is insufficient to recommend routine ward AEDs; earlier defibrillation must be weighed against compression interruptions.
Measurement properties of pulmonary function measurement and patient-reported outcome measures in patients with multiple rib fracture without flail segment; validation study alongside the multicenter FixCon trial
Using the multicenter FixCon RCT population (n=180), tests how reliable and valid spirometry, pain scores, and quality-of-life instruments are as outcome measures for multiple rib fractures without a flail segment — informing which endpoints future chest-trauma trials should use.
Does Surgeon Experience Affect Outcomes in Robotic Cholecystectomy for Emergency Biliary Disease? A Statewide Analysis
Statewide cohort examining whether surgeon experience affects outcomes of robotic cholecystectomy in emergency general surgery, amid a >3-fold rise in robotic emergency operations since 2011. Adds experience-stratified outcome data to the debate over robotic adoption in the acute-care surgery setting.
Early fixation of traumatic mandible fractures is associated with decreased morbidity and resource utilization
In a TQIP analysis (2017-2023) of closed mandible fractures, earlier surgical fixation was associated with fewer in-hospital complications and lower resource use, challenging the prior consensus that repair timing does not affect outcomes.

Efficacy and safety of oxiracetam for cognitive and functional outcomes after acute traumatic brain injury in Chinese populations: a systematic review and meta-analysis of randomized controlled trials
Pooling 33 RCTs (2,864 patients), oxiracetam raised post-treatment MMSE by ~4.7 points after acute TBI when background therapy was balanced; evidence is limited to Chinese trials and overall certainty remains uncertain.
Prehospital transport prioritization and time-varying selection bias in traffic-related multi-patient incidents: a nationwide retrospective cohort study
Using a doubly-robust causal analysis of 143,130 patients from Japanese traffic multi-patient incidents, being transported first ("priority transport") carried higher risk of death/severe injury, most strongly at the shortest on-scene times — a U-shaped pattern consistent with the sickest patients being selected for rapid transport rather than harm from transport order. A methodological caution for interpreting transport-outcome associations in trauma-system research.
Beyond TRISS: A Contemporary Expected Mortality Model for Trauma quality review — Trauma Quality Improvement Program, 2017-2024
Trained on 5.4 million TQIP patients, the new CEM-Trauma model predicted in-hospital death more accurately than the aging TRISS, offering a contemporary benchmark for trauma-center quality review.
Decompressive craniectomy: The potential association with long-term functional outcomes in children with traumatic brain injury
Using the international ADAPT pediatric severe-TBI dataset, this analysis tested whether decompressive craniectomy improves long-term functional independence in children — addressing a question with little high-quality evidence and informing how aggressively to pursue surgical decompression in pediatric TBI.
Opioid-Associated vs Undifferentiated Out-of-Hospital Cardiac Arrest: Examining differences in outcomes and the relationship with Utstein variables
In the British Columbia registry, opioid-associated OHCA (13% of cases, median age 40) showed no overall difference in favourable neurological survival versus undifferentiated arrest, but the relationship between Utstein predictors and outcomes differed by sex, initial rhythm, and witnessed status — a caution that mixing opioid cases into observational OHCA analyses can distort findings.
Prospective Randomized Controlled Study Comparing Decompressive Craniectomy with Watertight Duraplasty and without Watertight Duraplasty in Traumatic Brain Injury
In this 200-patient RCT, performing decompressive craniectomy for TBI without watertight duraplasty produced similar postoperative complications (CSF leak, infection, hydrocephalus, hygroma), mortality (28% vs 24%), 6-month GOS, and cranioplasty outcomes compared with watertight duraplasty — but with significantly shorter operative time and less intraoperative blood loss, arguing the dura need not be closed watertight during DC.
Comparison of two automated pupillometry indices in patients with acute brain injury: the prospective multicentre LYNX cohort study
In 108 acute brain-injury patients (7,089 paired readings), the two commercial pupillometry indices NPi and QPi correlated and both predicted poor 6-month outcome, but QPi was far more sensitive to propofol/sufentanil. The indices are not interchangeable in sedated ICU patients, and QPi's apparent link to raised ICP is likely confounded by sedation.
Amiodarone After Conversion From a Non-shockable to a Shockable Rhythm in Out-of-Hospital Cardiac Arrest: A Propensity Score-Matched Analysis from the German Resuscitation Registry
In 3,686 propensity-matched OHCA patients whose rhythm converted from non-shockable to shockable, amiodarone during resuscitation was associated with higher ROSC-on-admission (26.7% vs 23.0%), 24-hour survival (21.4% vs 14.7%), and survival to discharge (6.5% vs 4.2%); the gain in favourable neurological outcome was not statistically significant. Suggests a group currently outside the "after three shocks" guideline may still benefit from amiodarone.
Early Post-ROSC Laboratory Phenotypes and Clinical Outcomes after Out-of-Hospital Cardiac Arrest: A 10-Year National Cohort Study
Latent class analysis of routine labs within 6 hours of ROSC in Singapore's national OHCA cohort identified three reproducible phenotypes — multi-organ dysfunction, homeostatic, and immune-dysregulated — that independently stratified neurological recovery and mortality out to 3 years. A step toward lab-based, phenotype-guided post-arrest care, pending external validation.
The Epidemiology of Paediatric Out-of-Hospital Cardiac Arrest in Australia and New Zealand: A Report from the Australasian Resuscitation Outcomes Consortium Epistry (Aus-ROC)
In the first binational pediatric OHCA registry report (2017-2023), survival to 30 days/discharge among EMS-treated children was 10% (lowest in infants at 7.9%), with a bimodal incidence peaking in infants and adolescents. Bystander-witnessed arrest, initial shockable rhythm, etiology, older age, and EMS response time predicted survival — arguing for age- and context-specific prevention and resuscitation strategies.
Time to Return of Spontaneous Circulation and Long-Term Outcomes in Bystander-Witnessed Out-of-Hospital Cardiac Arrest Survivors
In 2,583 Danish bystander-witnessed OHCA patients surviving at least 30 days, a longer time from emergency call to ROSC was associated with worse long-term outcomes — more anoxic brain damage, more nursing-home admission, and lower return-to-work — reinforcing that minimizing time-to-ROSC matters not only for immediate survival but for functional recovery.
Age-adjusted shock index vs. reverse shock index multiplied by Glasgow Coma Scale to evaluate mortality in pediatric trauma: a systematic literature review and meta-analysis
Pooled systematic review and meta-analysis comparing two bedside physiologic triage scores — the Shock Index Pediatric Age-adjusted (SIPA) and the reverse Shock Index multiplied by GCS (rSIG/rSIM) — for predicting mortality in injured children. Informs which score better flags high-risk pediatric trauma patients for early intervention.
Efficacy and safety of intraoperative red blood cell salvage transfusion for spinal deformity surgery: a systematic review and meta-analysis
Pooled analysis of studies comparing spinal deformity surgery with versus without intraoperative cell salvage, assessing whether cell salvage cuts allogeneic transfusion exposure in the era of routine antifibrinolytics and restrictive transfusion thresholds.
Trauma governance and system maturity: A cross-national analysis of authority, funding, enforcement, and surveillance in 37 countries
Across 37 countries, those with any formal trauma-governance entity had far lower injury mortality (6.9 vs 22.2 per 1,000) and higher trauma-system maturity. The benefit was concentrated in having any governance structure versus none (+0.66 maturity points adjusted), making basic governance a high-yield, scalable target for lower-middle-income nations.
Outcomes Following Impedance Threshold Device Use During Out-of-Hospital Cardiac Arrest
Large nationally representative cohort assessing whether impedance threshold device (ITD) use during non-traumatic out-of-hospital cardiac arrest is associated with better prehospital and longer-term outcomes, where prior evidence has been equivocal.
Prehospital Prognostication after Out-of-Hospital Cardiac Arrest in Tertiary Care Centers: The R-EDByUS Score in the JAAM-OHCA Registry
Using the Japanese JAAM-OHCA registry, the R-EDByUS score — derived from prehospital variables alone — was externally validated for predicting poor 1-month neurological outcome (CPC 3-5) in OHCA patients transported to tertiary centers, supporting its use for early risk stratification in both the prehospital-ROSC and ongoing-CPR groups.
