Comparative Study Clinical Trial
[Procalcitonin plasma concentrations and systemic inflammatory response following different types of surgery].
Procalcitonin (PCT) is currently recommended as a suitable parameter to detect and to evaluate the course of bacterial, fungal or parasitic infections. However, recent studies provide evidence that surgical trauma and humoral mediators of inflammation, respectively,may induce PCT synthesis, thereby reducing the validity and reliability of PCT as an "infection-monitoring" parameter. The aim of the present study was to assess and to compare PCT and CRP (C-reactive protein) plasma concentrations in patients presenting without infection following different types of surgery in the absence or presence of a systemic inflammatory response syndrome (SIRS). ⋯ Postoperative PCT plasma concentrations in patients presenting without signs of infection are largely influenced by the type of surgical procedure. During the first and second postoperative day PCT concentrations are more frequently elevated in patients after major abdominal, major vascular and thoracic surgery compared to patients undergoing minor, aseptic operations. Thus an "infection monitoring" considering PCT value analysis during the postoperative course may transiently be impeded after major and particularly after intestinal surgery during the first 2 days postoperatively, whereas it appears not to be substantially affected by the presence or absence of systemic inflammatory response.
