Immediate postinjury procalcitonin levels related to final survival

Procalcitonin (PCT) levels have been proved to be a very useful marker not only in severe microbial sepsis but also in SIRS and MOFS. Severe polytrauma is one typical example of SIRS without microbial infection, at least during the first days. High PCT levels are often seen in multiple trauma, sometimes higher than that seen in septic shock. The prognostic meaning of these high PCT levels is practically unknown and has to be further investigated.
