Abstract

Background and aims: Analysis of risk factors for the occurrence and severity of crush syndrome in pediatric trauma victims of the 2008 Wen-chuan earthquake. Aims: We undertook an analysis of the factors affecting the occurrence and severity of crush syndrome (CS) after crush injury (CI) in pediatric trauma victims of the Wenchuan earthquake which hit the SiChuan WenChuan area of China. Methods: A retrospective review of the medical records of 98 patients who were transferred to our hospital was performed. We collected data on factors influencing such as age, gender, time under ruins, amputation, wound infection, renal replacement therapy(RRT), and other factors.Possible risk factors impacting on CS severity were analyzed. Results: Fifteen patients with CS came from 59 patients with extreme CI. The incidence of CS reached 15.3% in pediatric trauma victims after earthquake and 25.4% in extreme CI. Seven risk factors were assessed with logistic regression analysis for three outcomes relating to CS. The influencing factors of age, time under ruins, and closed CI gave log-odds ratio (log-OR) of 1.046, 1.220, and 0.062, respectively (all P<0.05). Asignificant difference was found between those patients with CS fasciotomy incision and those with other operative incision (P<0.05). Conclusions: The occurrence of CS chiefly derives from extreme CI, and also has a significant association with age, time under ruins, and closed CI in children, but gender, upper or lower limbs injury, wound infection, and amputation, were not. Infection of incisional wounds after CS fasciotomy is a risk factor for aggravation of CS.
