Bacteriological profile of surgical site infection and associated risk factors in obstetrics and Gynecology patient

Abstract

Surgical site infections (SSI) are the second most common cause of nosocomial infections in obstetrics and gynecology patient. It has been estimated that SSI develops in at least 2% of hospitalized patients undergoing operative procedure. Knowledge of the most likely causative organisms and antibiotic sensitivity or resistance pattern will be of great help in managing the patients. Patients in the Obstetrics and Gynecology department, who had developed signs and symptoms of SSI were included in this study. Surgical sites were considered to be infected according to the set of clinical criteria recommended by CDC definition 1992. When infection was clinically suspected, the exudate was collected from the depth of the wound using two sterile cotton swabs one for preparing smear and another for culture. All the specimens collected were transported immediately to the laboratory for further processing. The samples collected were processed by conventional method according to CLSI guidelines. A total of 300 cases were examined for SSI and 25 were found to be clinically infected with the rate of incidence of infection 8.33%. The commonest organism was klebsiella, Pseudomonas 61.5% followed by staphylococcus 15.3%.
