Clinical analysis of surgical site infection in patients with type Ⅰ incision orthopedic foot and ankle surgery / 国际外科学杂志

ABSTRACT

Objective To investigate and analyze the surgical site infection rate,clinical characteristics,risk factors and pathogens in patients after type Ⅰ incision orthopedic foot and ankle surgery,which may provide a basis for preventing surgical site infection in foot and ankle surgery.Methods Patients undergoing type Ⅰ incision orthopedic foot and ankle surgery from Jun.2011 to Jun.2015 were investigated retrospectively.Clinical data of cases with surgical site infection were collected and analyzed.Incidence of surgical site infection,clinical features,risk factors and pathogen distribution were studied.Results Seven hundred and sixty-one patients were undergoing type Ⅰ incision orthopedic foot and ankle surgery,surgical site infection occurred in 42 patients with an infection rate of 5.5％.In terms of age,gender,anesthesia,smoking,drinking,rheumatoid arthritis,gout,number of incisions and recovery after open injuries,no significant difference of surgical site infection rate were found.Diabetes mellitus complicated with peripheral neuropathy increased the risk of surgical site infection compared with nondiabetic patients.Patients who had an operative time more than 3 hours had a greater risk of surgical site infection compared with those less than 1 hours.The presence of intra-operative implants increases the risk of surgical site infection compared with patients with external fixations or without implants.Conclusions Surgical site infection is a common complication for the patients after type Ⅰ incision orthopedic foot and ankle surgery.Diabetes mellitus complicated with peripheral neuropathy,long operation time and intra-operative implants may be the high risk factors for surgical site infection.
