Objective: To discuss the relative factor, development tendency and prevention of the fatal complications in traffic accident injury.
Method: We observed injury severity scale (AIS-ISS), clinical response time, and occurrence in traffic accident injury with fatal complications. Ridit mathematical statistics and Q test were used.
Result: There were high ISS and long clinical response time in traffic accident injury with fatal complications. A significant relation was found between complications and the progress of time after trauma, thereby the clinical course could be divided into phases of cerebral hernia and shock (or acute), transition, infection and multiple organ dysfunction syndrome (MODS). There was higher head AIS in the cerebral hernia. ISS of shock patients was significantly higher than that of the others. Massive infections occurred in the patients with extremity trauma. There was a significant relation between the occurrence of MODS and infection.
Conclusion: The occurrence of fatal complications is related to the location and severity of injury in traffic accident injury. A regularity is present in the occurrence of fatal complications with time progress.
