In a retrospective analysis, clinical data and histological specimens were obtained from patients (n = 59) who died of severe injury. Three groups with comparable injury severity were differentiated according to the time of death. In group A (death, within 24 h) (n = 15) despite multiple injuries, patients almost always died from brain injury. Pulmonary failure was the leading cause of death in group B (death, days 2-7) (n = 16). The majority of group C patients (death, > 7 days) (n = 28) died of multiple organ failure. Organ weights at autopsy were all pathologically high but did not show an association with the amount of intravenous volume infused during intensive care. Organ histology revealed signs of interstitial edema and infiltration of polymorphonuclear leukocytes in group B patients especially in the lung, and in all groups to a lower degree in liver and kidney. The distribution of interstitial edema and cell necrosis appeared to be organ-specific. Our data confirm the presence of a generalized inflammatory reaction in patients with severe trauma. The pattern of organ failure, in addition to known pathogenetic changes (mediators, endotoxemia, etc.), appears to be influenced by organ structure and perfusion.
