Abstract：Objective To get known the occurrence condition of occupationa1 exposure in surgica1 staff，and to exp1ore the app1ication of PDCA cyc1e management on occupationa1 protection in the operating room.Methods Surgery doctor，anesthesia doctor，operation nurse，practice nurse and operation room c1eaning staff from January 2014 to December 2015 in obstetrics and gyneco1ogy operation room of our hospita1 were se1ected as the research object，before the imp1ementation ranging from January to August in 2014 was se1ected as the contro1 group，after the imp1ementation ranging from September 2014 to Apri1 2015 was chosen as the first research group，and qua1ity further improved ranging from May to December in 2015 was c1assified into the second research group.The condition of occupationa1 exposure of different position and different 1ength of service operating room staff was compared，and the condition of occupationa1 exposure of working in different positions before and after imp1ementation of PDCA in the different groups was recorded.Results The incidence rate occupation exposure of practice nurse was highest，which was 89%，compared with the other ranks，there was significant difference（P＜0.05）.The 1onger the 1ength of service，the 1ower the incidence rate of occupationa1 exposure.The incidence rate of occupationa1 exposure rate of 1ength of service more than five years was 23.3%，which was 1ower than that of other workers，with significant difference（P＜0.05）.The incidence rate of occupationa1 exposure ratein various surgica1 staff in the second research group was 1ower than that in the contro1 group and the first research group，with significant difference（P＜0.05）.Conclusion App1ication of PDCA cyc1e management in the operating room can effective1y decrease the incidence rate of occupationa1 exposure in working staff，it is worthy of c1inica1 promotion and app1ication.
