To investigate the hospital infection related factors and preventive measures of occurrence in the obstetrical department.

The clinical data of 109 obstetric cases with nosocomial infection in our hospital from January 2013 to December 2014 were analyzed, retrospectively.

The infection in respiratory tract, upper and lower respiratory tract infection was the highest (44.03%), followed by operation incision (23.85%) and urinary tract (12.84%). There were 36 (33.03%) cases with cesarean section infection, 24 (22.02%) cases with normal labor without side-cut infection, 19 (17.43%) cases with eutocia side-cut infection, 17 (15.60%) cases with ectopic pregnancy infection, 13 (11.93%) cases with family planning infection. The results of laboratory tests showed that 52 (47.71%) strains of pathogenic bacteria, including 16 (30.77%) strains of Escherichia coli were detected.

Patients with reduced resistance and less activity is the main cause of respiratory infection, and cesarean section with indwelling catheter are a major causes of urinary tract infection. The medical staff and obstetric patients should have aseptic concept consciousness, and strictly comply with the implementation of aseptic operation flow and effective disinfection and isolation system, which are the main measures to prevent nosocomial infection, ensure maternal in good mental state during the hospitalization process, and could reduce the incidence of obstetric infection.
