Abstract
- Unlabelled: There is compelling data from several clinical studies on the impact of various anti- and proinflammatory mediators on traumatized patients. Immediate trauma-related results, however, are only available from animal experiments so far. Therefore, in this prospective clinical study the following questions were addressed: (I) Is there any marker in the preclinical phase that give information independent of and better than conventional studies conducted so far, (II) does this possible factor prove to be a (significant) predictor of late complications and/or poor overall outcome, and (III) does this mediator provide information that can alter treatment decisions?<br />Methods: Upon approval of the local IRB/IEC, 85 patients (pts) were enrolled who suffered from multiple injuries. The pts were rescued by the helicopter-based service of the German Army Hospital in Ulm. The first blood samples were drawn at the site of accident and at admission, then in hourly to daily intervals. The plasma concentrations of following mediators were analyzed: Prostanoids, products of O2-radicals, soluble adhesion molecules, various cytokines, C-reactive protein, creatinine kinase, and neopterin. All values were calculated in relation to the actual plasma protein content to eliminate fluid-induced dilution effects. Subsets of patients were performed according to the severity of trauma (ISS < 9; 9-17; 18-31; > 32), based on the different injury pattern, and survivors versus nonsurvivors as well.<br />Results: As early as at the scene of accident, all patients revealed a severity-dependent increase in most mediators' plasma levels. There was, however, also a pattern-related inflammatory response that was most pronounced in pts who had suffered from thoracic trauma irrespective of whether it was associated with multiple trauma. In a total, 15 pts died within 72 h after the accident. In those casualties, the plasma concentrations of prostaglandin E2 (P < 0.03), glutathione (P < 0.01) as well as creatinine kinase (P < 0.05) were more markedly elevated when compared with survivors.<br />Conclusion: Although there were severity-dependent as well as pattern-related releases of various mediators, which in part were more apparent in nonsurviving patients, we failed in proving any predictive marker to specifically discriminate outcome.
