[Immunologic monitoring after severe trauma].

Trauma, burn injury, and major surgery lead to severe suppression of the immune system with an increased susceptibility to septic complications. Therefore, the monitoring of essential immune functions in the early and late post-traumatic course may permit trauma patients with an increased risk for infectious complications to be identified. Most functions of the specific and non-specific immune system can be determined with ELISA, RIA, or other immunological techniques. However, only a small number of these techniques demonstrate an acceptable sensitivity and specificity for infectious complications. Moreover, the techniques used in daily monitoring should be simple, reproducible and not expensive with regard to materials. For immunological monitoring we suggest two scoring systems (ISS; APACHE II), biochemical parameters (elastase, neopterin, CRP, lactate), and interleukin-6 plasma levels. The clinical relevance of this monitoring must be proven in clinical studies.
