30-Second Takeaway
- Whole blood resuscitation in civilian trauma is linked to lower early mortality and reduced product use versus components.
- Standard LMWH prophylaxis leaves over half of ICU patients subprophylactic by anti-Xa, with higher VTE risk in low levels.
- An interpretable CT-based AI tool accurately predicts mortality in gunshot wounds to the head using first HCT alone.
- Pediatric conflict trauma shows high hemorrhagic mortality with unbalanced transfusion, underscoring pediatric-ready MTPs in austere settings.
- Delayed ICU admission and underused early rehab both worsen post-ICU patient-centered outcomes, highlighting system-level targets for trauma programs.

Trauma resuscitation, ICU pathways, and perioperative complications: new data to sharpen protocols across the continuum of care
Whole blood resuscitation reduces early mortality in civilian adult trauma
This meta-analysis of 40 studies (49,776 adults) compared whole blood with component therapy for traumatic hemorrhage. Whole blood was associated with lower 24-hour mortality overall (OR 0.76; 95% CI 0.60–0.95), despite substantial heterogeneity. In civilian settings, whole blood reduced 24-hour mortality (OR 0.73; 95% CI 0.57–0.93), an absolute risk reduction of about 4–5 percentage points. Civilian cohorts also showed lower 30-day mortality and required fewer transfused units with whole blood. No mortality benefit was observed in military settings, emphasizing context-specific implementation and ongoing evaluation.
Interpretable CT-based AI model predicts mortality after civilian GSWH
This single-center cohort included 222 adults with civilian gunshot wounds to the head who underwent initial noncontrast head CT. An attention-based multiple-instance learning model used the index CT to predict in-hospital mortality with high discrimination (AUC 0.92; 95% CI 0.87–0.94). At the chosen threshold, sensitivity was 0.88 and specificity 0.87 for mortality prediction on an independent test set. Attention maps consistently focused on brainstem, deep midline, and ventricular injuries in high-risk cases, aligning with known lethal injury patterns. These findings support CT-first, AI-aided prognostication for GSWH, while external validation and workflow integration remain necessary.
Conflict-injured children have high mortality and unbalanced transfusion in deployed MTFs
This DoD Trauma Registry cohort analyzed 5,695 conflict-injured children treated at deployed military facilities from 2001 to 2022. Overall mortality was 9.4%, with nonsurvivors younger, more severely injured, and more likely to have burns. Nonsurvivors had substantially higher blood loss and more frequent transfusions, yet neither survivors nor nonsurvivors received balanced products. Packed red cell-to-platelet ratios were markedly unbalanced, at 4:1 in nonsurvivors and 6.5:1 in survivors. The authors advocate standardized pediatric equipment, early hemorrhage control, and protocols emphasizing recognition and balanced resuscitation for pediatric hemorrhagic shock in austere settings.
Subprophylactic anti-Xa levels are common and linked to higher VTE in ICU patients on LMWH
This systematic review included 39 studies with 7,124 critically ill adults receiving LMWH for VTE prophylaxis. Only 47% of patients achieved target prophylactic anti-Xa levels, indicating frequent underdosing or altered pharmacokinetics. Subprophylactic anti-Xa levels were associated with nearly triple VTE risk (unadjusted OR 2.87; 95% CI 1.42–5.81), albeit with low certainty. Male sex, higher weight, and higher BMI showed moderate-certainty associations with subprophylactic levels. These data support considering anti-Xa monitoring and dose adjustment in high-risk ICU patients rather than relying solely on standard fixed dosing.
