Clinical research on related factors for appendix surgical incision infections

OBJECTIVE To explore the risk factors for surgical incision infections after appendix surgery.METHODS From Jan.2008 to Dec.2010,a total of 1580 patients receiving appendix surgeries were involved in the study.Patients with surgical incision infection after appendix surgery were set as the observation group,the patients without incision infections were set as control group according to a 1∶1 ratio.Single factor analysis and logistic regression analysis were performed for the factors that may affect the incision infections.RESULTS Totally 5.69% of patients who underwent appendix surgeries were with incision infection single factor analysis showed that 12 factors were related to incision infection(P0.05).Logistic analysis indicated that the risk factors were high BMI,combination with other diseases,long operation time,the appendix rotting gangrene appendiceal perforation,and retrograde resection;OR values were 3.23,3.10,2.98,2.76,and 2.62,respectively.CONCLUSION The incidence of the incision infections after appendix surgery is high and it is associated with multiple factors.Corresponding measures should be implemented on the risk factors to prevent and reduce incision infection.
