Modified Delphi consensus recommendations for the use of negative-pressure wound therapy in orthopedic trauma and complex wounds in low- and middle-income countries: an African consensus study
Multinational African Delphi produced 14 recommendations for NPWT in open fractures/complex wounds in resource-limited settings. Strongest agreement: use NPWT only as an adjunct to standard open-fracture care, after adequate surgical debridement, and always followed by timely definitive soft-tissue reconstruction — not as a substitute for it. Technical/organizational parameters reached lower consensus.
Splenic artery embolization versus surgery for blunt splenic injuries: a systematic review, meta-analysis and trial sequential analysis stratified by hemodynamic status
Across 33,148 patients, splenic artery embolization (SAE) was associated with lower mortality, shorter hospital and ICU stays, and less thromboembolism than surgery — with a survival benefit that persisted even in hemodynamically unstable patients, challenging guideline preference for primary surgery in unstable cases. Confounding by indication from observational data is the key caveat.
Delivery outcomes following previous pelvic ring injury: A systematic review, meta-analysis and evidence informed management pathway
Across 10 studies (1253 women, 1719 deliveries), cesarean rate after a prior pelvic ring injury pooled at ~40% but trial of labour succeeded in 86%. Retained implants, operative fixation, and most fracture patterns are not barriers to vaginal delivery — supporting an individualized trial of labour with shared decision-making rather than defaulting to cesarean.
Closed reduction and percutaneous fixation versus open reduction and internal fixation for displaced medial malleolar fractures: a randomized controlled trial
Two-center RCT (50 patients) found closed percutaneous fixation and ORIF gave comparable 6-month function and complication rates for displaced medial malleolar fractures. The trial was not powered for equivalence, so findings are preliminary and need larger confirmation.
Thoracoscopic internal fixation, open surgical internal fixation, and conservative treatment of rib fractures: differences in postoperative rehabilitation and chest volume (a randomized controlled trial)
In multiple rib fractures, both thoracoscopic and open fixation restored thoracic volume and improved early quality of life versus conservative chest-band management; thoracoscopic fixation caused less surgical trauma with better short-term rehabilitation and equivalent thoracic recovery and complication rates. Small single-center trial.
Explosive Weapons Trauma Care Collective (EXTRACCT) Blast Injury Clinical Practice Guideline: Traumatic Brain Injury From Blast and Penetrating Mechanisms in Settings With Variable Resource Availability
First resource-stratified guideline for blast/penetrating TBI in low-resource and conflict settings. Core message: aggressively avoid hypotension and hypoxia, use non-contrast head CT (add CTA for penetrating injury), hyperosmolar therapy first-line for raised ICP, noninvasive multimodal neuromonitoring when invasive ICP monitoring is unavailable, and prioritize early transfer to neurosurgical care.
Venous thromboembolism (VTE) in neurosurgery: assessing the evidence for a VTE prophylaxis guideline
Scoping review that informed a 5-center New Zealand consensus VTE-prophylaxis guideline. Bottom line for trauma/TBI: mechanical prophylaxis (intermittent pneumatic compression) for essentially all patients, with LMWH started 24–72 h postoperatively — or after confirmed stable neuroimaging in TBI — consistently reducing VTE without a rise in major bleeding; timing and duration individualized by subgroup.
Correlation of functional and radiological outcome after surgical treatment of acetabular fractures with quadrilateral plate involvement: a meta-analysis
Pooling 12 studies (336 patients), better radiological reduction (MATTA) correlated with better functional scores mainly at the extremes (excellent vs poor), but agreement was only moderate (51–58%) — reinforcing anatomic reduction as a goal while suggesting reduction quality alone does not determine outcome and that current functional scoring tools may be inadequate.
Patient-reported outcome measures within European cohorts of severely injured patients: a systematic review and meta-analysis
Pooling 119 European studies, severely injured patients still show persistent impairment at 1 year (EQ-5D-3L index 0.70) — recovery is incomplete, and inconsistent PROM reporting limits comparability, arguing for standardised long-term outcome measurement after major trauma.
Effect of laryngeal mask airway versus endotracheal intubation on survival in out-of-hospital cardiac arrest: a meta-analysis of randomized controlled trials
Pooling 19 RCTs (11,982 patients), LMA gave faster airway placement and higher first-pass and CPR success than endotracheal intubation, with no difference in survival or mortality — supporting LMA as a reasonable, individualized alternative, especially where intubation expertise is limited or chest-compression interruptions must be minimized.

Temporal trends in critical care burden and outcomes of Andes virus-associated hantavirus cardiopulmonary syndrome: a national Chilean cohort
Hantavirus cardiopulmonary syndrome remains highly lethal (20.5% in-hospital mortality; ~30-33% among those needing mechanical ventilation or ECMO) and demands heavy respiratory support; mortality rose during the COVID-19 pandemic, underscoring ICU surge vulnerability.
Balanced crystalloid versus saline for resuscitation in adult sepsis: a systematic review and meta-analysis
Pooling 8 studies (8,173 patients; 7 RCTs), balanced crystalloids reduced mortality versus normal saline (RR 0.92, 95% CI 0.86-0.98) with fewer episodes of acute kidney injury, hyperchloremia, and renal replacement therapy, plus more ICU-, ventilator-, and vasopressor-free days — supporting preferential use of balanced solutions over saline for fluid resuscitation in sepsis (moderate certainty).
Impact of altered consciousness on the risk of fasciotomy for acute compartment syndrome following traumatic tibial fracture
Across 119,393 tibial fractures, obtunded patients (sedated/intubated, GCS<9, or severe intoxication) had modestly higher fasciotomy rates for suspected acute compartment syndrome (OR 1.14) even after adjustment — when clinical exam is unreliable the threshold to operate drops, strengthening the case for objective intracompartmental pressure monitoring in sedated trauma patients.
Trends in the incidence and outcomes of cardiopulmonary resuscitation-induced consciousness in out-of-hospital cardiac arrest: a retrospective study
CPR-induced consciousness occurred in 3.3% of OHCA and rose over 16 years; it was independently associated with markedly better survival to discharge (OR 2.71), so signs of consciousness during CPR may flag favourable physiology rather than a reason to interrupt resuscitation.
Pulseless electrical activity versus asystole as initial pulseless rhythm in children: challenging convention regarding non-shockable rhythms
Across 9,423 pediatric in-hospital cardiac arrests (2000–2023), asystole carried lower odds of ROSC and restoration of circulation than PEA, but the survival-to-discharge difference was driven almost entirely by neonates/NICU events — in older children survival did not differ. Challenges lumping PEA and asystole together as one "non-shockable" category.
Surgical rib fixation in pediatric patients: Following the adult trend or a different story?
Largest pediatric SSRF cohort to date: only 0.31% of 28,465 pediatric rib-fracture patients underwent surgical rib fixation, and unlike the rising adult trend, pediatric use stayed flat and confined to older children with flail chest, high ISS, or open chest injuries. SSRF-treated children had zero mortality vs 7.3% non-operative, but heavy selection means pediatric indications remain undefined.
Non-invasive brain stimulation for cognitive impairment after traumatic brain injury: an umbrella review of systematic reviews
Umbrella review of 10 systematic reviews (42 primary studies) found no consistent evidence that non-invasive brain stimulation (rTMS or tDCS) improves cognition after TBI, and all underlying reviews were low or critically low quality by AMSTAR-2. Routine clinical use for post-TBI cognitive rehabilitation is not supported outside research or carefully selected cases.
Clinical outcomes of interventional radiology versus operative management in hemodynamically stable and unstable moderate-to-severe high-grade blunt renal trauma
In high-grade (AAST ≥4) blunt renal trauma, interventional radiology was associated with substantially lower in-hospital mortality than operative management in both hemodynamically stable (aOR 0.21) and unstable (aOR 0.08) patients, with no increase in complications — supporting angioembolization as a safe primary strategy even in unstable patients at Level I centers. Confounding by indication is the key caveat.
Artificial intelligence for predicting 30-day mortality after emergency laparotomy
Using 8,293 cases from the Australian/NZ ANZELA-QI national audit, machine-learning models (multilayer perceptron) and multivariate logistic regression matched the established NELA risk model for predicting 30-day mortality after emergency laparotomy — AI offered no clear advantage over existing risk tools.
Aging at the Cellular Level: An Exploratory Analysis of the Effect of Age on Platelet Dynamics in Injured Patients
In 716 injured adults not on antiplatelet drugs, increasing age was independently associated with lower platelet count and aggregation alongside hypercoagulable clot dynamics; in patients ≥55, low count and reduced aggregation at admission suggested higher mortality — flagging age-related platelet dysfunction as a potential target in resuscitation of older trauma patients.

Predicting the Prehospital Blood Transfusion Need in a Large Metropolitan Center
Among 25,473 trauma patients, prehospital vitals of SBP <90 mmHg plus HR ≥110 bpm gave the highest positive predictive value (56%) for needing transfusion within 4 h of ED arrival; other criteria (SBP <70, EMS-witnessed arrest) ranged 51–53%. Supports simple physiologic triggers to select patients for prehospital blood.
Analysis of factors associated with emergency airway intervention after extubation in patients surgically treated for traumatic cervical spinal cord injury
Of 221 surgically treated cervical spinal cord injuries extubated without planned airway management, 23% needed emergency airway intervention. Neurogenic shock, complete motor impairment, and vertebral artery injury stratified risk (100% / 70% / 24% / 3% with all / two / one / no factors) — a practical way to flag who warrants prophylactic airway management or closer monitoring.
Challenging convention: a secondary data analysis of circulation-first versus airway-first triage in trauma patients receiving blood transfusions
Among 84 hemorrhagic-shock patients who received both blood and intubation within 30 min, a circulation-first approach (CAB — blood before the tube) showed no difference in mortality or hospital length of stay versus airway-first (ABC), challenging the long-standing convention of intubating before transfusing. LITES centers favored CAB for penetrating trauma. Small sample limits generalizability and the authors call for prospective multicenter trials.
Beyond damage control: Functional preservation and avoidance of iatrogenic harm in combat vascular injury and fasciotomy
In combat vascular trauma, damage-control moves (extensive exposure, shunting, ligation, prophylactic fasciotomy) save life and limb but carry real iatrogenic cost; select them by physiology, ischemic burden, evacuation conditions and available expertise rather than reflexively, and repair/shunt major named arteries whenever perfusion is threatened.
