Abstract: PURPOSE: To investigate the status and causes of sharp injuries in nurses during oral and maxillofacial surgery, in order to make effective protective measures to reduce the occurrence of sharp injuries. METHODS: A retrospective study was conducted on sharp injuries for 102 nurses in the operating room during January 2016 to March 2017 on the basis of questionnaire surgery. The types of sharp injuries, the causes and the operation steps were analyzed. According to the results of investigation and analysis, appropriate protective measures were taken. RESULTS: The incidence of sharp injuries was 87.2% in nurses during oral and maxillofacial surgery, 57.1% in nurses with ≥5 years of working experience, 95.6% in nurses with fewer than 5 years of working experience, 91.6% in new staff and 95.6% in internship students. Injury objects induced by needles, blade, glass; injury happened during transmission of equipment, postoperative arrangement of equipment and cleaning equipment. CONCLUSIONS: Due to the fine surgical instruments, many kinds of needles, long operation time and more chances to contact sharp instruments, sharp injuries are prone to happen during oral and maxillofacial surgery. By targeted prevention measures, sharp injuries can be effectively prevented.
