Nosocimial Infection and Perioperative Antibiotic Usage in Clean Surgical Sites:An Investigation

OBJECTIVE To investigate the surgical site infection(SSI)in clean surgical sites and the perioperative antibiotic usage.METHODS The incidence of SSI and the antibiotics usages in 842 cases during perioperative were analyzed retrospectively in 32 hospitals.RESULTS One case with nosocomial infection was found(0.12%).The use rate of antibiotics was 98.57%.Among 802 cases using prophylactic antibiotics,the antibiotics were given in 181 cases thirty minutes to two hours before operation.136 cases were given 24 h before operation.And 485 cases were given after operation;195 cases stopped using antibiotics after 24 h,472 cases stopped using antibiotics after 4-6 days and 135 cases stopped to use antibiotics after 7 days.CONCLUSIONS The major problem is excessive use of antibiotic in clean surgical site during perioperation,long duration of antibiotics prophylaxis,more expensive antibiotics and unnecessary combination of antibiotics,suggesting that it be important to strengthen the management of antibiotics.
