A new polymeric material, poly-N-acetyl glucosamine (p-GlcNAc) fiber, has been identified and is effective in achieving hemostasis in surgical procedures and trauma. The p-GlcNAc material is purified from large-scale cultures of a marine microalga. ⋯ The p-GlcNAc fiber has a unique beta-tertiary structure.

Comparative Study
Comparison of poly-N-acetyl glucosamine with commercially available topical hemostats for achieving hemostasis in coagulopathic models of splenic hemorrhage.
The hemostatic quality of the poly-N-acetyl glucosamine (p-GlcNAc) patch was compared with a fibrin sealant, fibrin bandage, and cellulose patch. ⋯ Poly-N-acetyl glucosamine was effective at controlling bleeding in animals with experimentally induced or genetic coagulopathic disorders.

This study sought to define the role of transiliac sacral rods used in combination with an external fixator for the management of unstable pelvic fractures. ⋯ For type C pelvic fractures without significant iliac bone involvement, surgical management with posterior transiliac fixation using sacral rods and anterior external fixation yields good radiologic results. The functional results correlated primarily with avoidance of complications and not necessarily with the radiologic results.

End-tidal carbon dioxide (Petco2) concentration is a marker of the pathophysiologic state because it is a reflection of cardiac output. Petco2 correlates with outcome after prehospital primary cardiac arrest, but association with outcome from prehospital trauma has not been established. ⋯ Only 5% patients with Petco2 < 3.25 kPa survived to discharge. Petco2 at t20 is of value in predicting outcome from major trauma.
