30-Second Takeaway
- Novel tough adhesive shows complete hemostasis in porcine solid-organ injury, outperforming current topical agents.
- Global trauma laparotomy data show no mortality difference between high- and low-ratio pre-op FFP:PRBC transfusion.
- Early impairment in cerebral oxygen-based autoregulation indices predicts 30-day mortality after severe TBI.
- Pediatric TBI outcomes worsen with ICP sustained above 14–15 mm Hg, below traditional 20 mm Hg thresholds.
- Continuing RAAS inhibitors in hemodynamically stable ICU patients does not increase advanced AKI and may improve survival.

Trauma surgery updates: hemorrhage control, neurocritical thresholds, and ICU management nuances
Hemostatic Tough Adhesive achieves complete hemostasis in porcine solid-organ trauma
In a porcine model of traumatic liver and spleen injury, a Hemostatic Tough Adhesive (HTA) achieved 100% hemostasis where commercial products often failed. The adhesive provided rapid bleeding control even under active hemorrhage and impaired coagulation conditions. It showed high tissue adhesion energy, several orders of magnitude above existing agents, and maintained stability through postoperative healing. These preclinical data suggest potential application for operative and damage-control management of solid-organ bleeding, pending human validation.
Pre-operative FFP:PRBC ratios show no mortality signal in global abdominal trauma laparotomy cohort
This planned secondary analysis of the GOAL-Trauma study evaluated 1768 patients undergoing trauma laparotomy across 187 centers in 51 countries. About 41% received pre-operative blood products, with high-HDI countries using more PRBC, FFP, and platelets, and low-HDI countries using more whole blood. High versus low pre-operative FFP:PRBC ratios were not associated with differences in 30-day in-hospital mortality (OR 1.52, 95% CI 0.89–2.64). Tranexamic acid use was low globally, and substantial variation in component therapy underscores ongoing equipoise around optimal pre-operative resuscitation strategies.
Early oxygen-based autoregulation indices predict mortality after severe TBI
In 218 severe TBI patients with invasive monitoring, multiple autoregulation indices were compared for 30-day mortality prediction. Within 24 hours, impaired ORx and OSRx were significantly associated with higher mortality, even after adjusting for age and admission GCS. Over the entire monitoring period, ORx and parenchymal PRx remained independently associated with mortality, whereas other indices were less informative. In patients with spreading depolarization monitoring, SD probability increased below MAP 85 mm Hg, suggesting a clinically relevant lower autoregulation limit. These data support incorporating brain oxygen–derived indices into early TBI management and targeting MAPs that avoid autoregulatory failure.
