title: [Blood coagulation parameters as prognostic factors in multiple trauma: can clinical values be an early diagnostic aid?].
abstract: BACKGROUND
  Polytraumatized patients develop complex changes in blood coagulation and fibrinolysis even before their arrival at the emergency room (ER). Hemostaseological parameters (i.e. antithrombine 3, alpha-2-antiplasmine, D-dimers) obtained upon admission however, permit advance differentiation of later mortality vs. survival and of possible future secondary organ failure with varying specification.
  
  
  OBJECTIVE
  Which clinical findings enable to identify such patients early in the ER even when no specialized hemostaseological laboratory is available?
  
  
  METHODS
  a) Prospective study of 40 polytraumatized adults upon arrival at the hospital; b) Blood sampling at the earliest possible time during takeover in the ER; c) Injury Severity Score (ISS) for descriptive purposes; d) Evaluation of the prehospital emergency physician's records in regard to respiratory therapy, fluid resuscitation, and arterial blood pressure; e) Statistics; Wilcoxon test, Spearman correlation coefficient.
  
  
  RESULTS
  All 40 patients (m:f = 28:12; mean age: 36 (SD: 16.6) years; mean ISS: 34.7 (SD: 11.4)) displayed advanced disseminated intravascular coagulation with secondary hyperfibrinolysis upon arrival in the ER. The amount of deviation from the hemostaseological norm could not be derived from either the correlation of the typical activated parameters of coagulation of fibrinolysis with the ISS or the analysis of the separate injuries. On the other hand the subgroup of patients displaying a systolic blood pressure of less than 100 mmHg at the site of the accident or upon arrival at the ER all had significantly lower antithrombine 3, protein C, and alpha-2-antiplasmine activities as well as increased concentrations of specific reaction products resulting from activated coagulation (thrombine-antithrombine 3-complex) and of fibrinolysis (D-dimers).
  
  
  CONCLUSIONS
  In our study patients with multiple injuries displaying a systolic blood pressure of less than 100 mmHg either at the scene of the accident or upon arrival in the ER showed coagulation values which by other investigators were regarded as a sign of potential secondary organ failure or death.
