Comparative study of blunt and penetrating diaphragm injuries in 46 patients

Objective To compare the clinical characteristics and severity of blunt and penetrating diaphragm injuries so as to guide the diagnosis and treatment of trauma. Methods A total of 46 patients with chest trauma complicated by diaphragm ruptures were divided into two groups, the blunt injury group and the penetrating injury group. The injury conditions of the two groups were studied comparatively. In addition, the trauma severity of the two groups were evaluated by trauma score systems. Results The incidence of blunt diaphragm injuries was lower than that of penetrating injuries. Blunt injuries were usually complicated by multiple traumas, but with slow injury advance, while penetrating injuries developed more quickly, and hemorrhagic shock occurred easily in the early period. Trauma scores showed that there was no significant difference in revised trauma score (RTS), injury severity score (ISS) and thoracic Abbreviated Injury Scale (AIS) between the two groups ( P 0.05 ), but the patients in the blunt injury group had lower Glasgow Coma Scale (GCS) and abdominal AIS ( P 0.05 ). Conclusions Blunt and penetrating diaphragm injuries have different clinical characteristics. So it is necessary to take different measurements to reduce the complications and improve the prognosis.
