The NTF_PT_2014 multicenter study aims to collect, store, and analyse plasma and serum from polytrauma-patients (injury severity score ≥25) and corresponding clinical data to address 1) how trauma modulates the release of danger molecules, inflammatory mediators, coagulation factors and novel biomarkers, 2) how the specific injury pattern affects the posttraumatic response and regenerative potential on an organ-, cell, and molecular level, and 3) how could a specific organ- and immune-monitoring predict the clinical outcome.
