Risk factors of wound infections after trauma in orthopedics

Objective To investigate the incidence and risk factors of wound infections after orthopedic trauma.Methods 348 patients with orthopedic trauma during Jul.2012 to Oct.2012 were selected by convenience sampling method,and the risk factors associated with the wound infections were analyzed.Results There were 192 open wounds,and the wound infection rate was 29.7%.There were156 cases of blunt trauma,and the wound infection rate was 5.1% after surgery.The average time of first disposing the open wounds was(4.3±2.4)h.The infection rate of open wounds was statistically significantly higher than in blunt wounds(χ2=34.177,P=0.000).The infection rate of multiple trauma wounds was statistically significantly higher than non-multiple wounds(χ2=7.693,P=0.006).The infection rate of shock patients was statistically significantly higher than non-shock patients(χ2=16.020,P=0.000).The first disposing time of infection patients was significantly different from the non-infection patients(F=12.84,P=0.000).The results were confirmed during Nov.2012 to Nov.2014.Conclusion According to the analysis results and the follow-up facts,we can see that the open wounds,multiple injury,shock and the first disposing time may be the risk factors of wound infections after orthopedics trauma.Shortening the first disposing time can improve the quality of wound care,reduce the infection rate of wound,promote the wound healing and increase the quality of life and satisfaction of patients.
