Open pelvic fractures associated with anorectal injuries:emergency management strategies and risk factors for mortality / 中华骨科杂志

ABSTRACT

Objective To investigate emergency management strategies and risk factors for mortality of open pelvic fractures associated with anorectal injuries.Methods Between April 2001 to April 2010,25 patients of open pelvic fractures associated with anorectal injuries were admitted to Shandong Provincial Hospital and Laigang Hospital,and early emergency treatments of this injury were retrospectively studied.Of these 25 patients,23 were male and the remaining 2 were female,and the mean age was 30.1±10.9 years (range,16-56 years).Fisher's exact test and multivariate logistic regression analyses were used to determine the risk factors related to mortality caused by this injury.Results Of the 25 patients,19 survived,other 6 patients were dead.The overall mortality was 24%.Fisher's exact test identified that the following risk factors including Tile classification,ISS,GCS and RTS were associated with the injury mortality.Patients with Tile C pelvic fracture ,ISS ≥ 25 points,GCS≤8 points or RTS≤8 points had a high probability of resulting in death.Multivariate logistic regression analysis was performed with the four variables noted above,and the results demonstrated that RTS ≤ 8 points was the only independent risk factor for mortality of patients with this injury.Conclusion Stabilization of hemodynamic condition,aggressive debridement and irrigation of the wound,early diversion of the fecal stream and early stabilization of pelvic fracture are critical strategies for the emergency management of open pelvic fractures associated with anorectal injuries.Furthermore,based on our findings,it can be concluded that RTS≤8 was reliable for predicting the probability of death in patients with this injury.
