Abstract: Objective: To investigate the characteristics of thoracic injuries with multiple traumas.Methods: A retrospective study was carried out in 245 patients with thoracic injuries combined with multiple traumas from October 2000 to October 2005.Total 245 patients were included this study,wherein 62 patients with brain injury,63 patients with abdominal injury,88 patients with pelvic and limbs injury and 32 patients with more than two parts of injuries.The average injury severity score(ISS)was 14.54±5.35.Results: Twenty-one patients underwent emergency thoracotomy while 132 patients underwent operation for multiple traumas.In the group,222 patients(90.61%) survived and 23 patients died with the mortality at 9.39%.Conclusions: Patients with thoracic injuries with multiple traumas are more severe.The pathogenesis of each injured part may interfere with clinical practice.Treatment should be concentrated on thoracic injury as well as associated traumas.
