某高等专科学校口腔医学实习生锐器伤发生情况及影响因素

目的]了解某高等专科学校口腔医学学生在实习期间发生医疗锐器伤的相关情况,探讨发生锐器伤的危险因素,为制定口腔医学实习生锐器伤防护措施提供科学依据。方法]2013年4月对该校2010级口腔医学专业毕业生采用回顾性问卷调查。结果]10个月实习期间,76.24%的实习生发生过锐器伤;共发生1 490次,人均约3.51次。造成锐器伤的器械依次是注射器针头、扩大针和根管挫;最易造成锐器伤的环节是口腔诊疗中;口腔外科门诊造成锐器伤次数最多。多重线性回归模型显示：防护知识缺乏、岗前无培训、操作技术不熟练、操作时心理紧张及精力不集中均是导致锐器伤发生次数增加的因素（β=1.02、0.77、0.56、0.31、0.74,P〈0.05）。结论]口腔医学实习生锐器伤发生率高,应建立健全口腔医学生职业防护教育体系,最大限度地减少锐器伤的发生。

Occurrence and Infl uencing Factors of Sharp Injury among Stomatological Interns from a Vocational College

Objective] To understand the incidence of sharp injury among stomatological majored interns from a vocational college, explore relevant risk factors, and provide scientific basis for developing protective measures against medical services related sharp injuries. Methods] A retrospective questionnaire survey was conducted in April 2013 among stomatological students who were admitted to the college in 2010. Results] During the 10-month internship, 76.24% of the interns reported sharp injuries. There were 1 490 episodes of sharp injuries, with an average of about 3.51 times per person. The injuries were mostly caused by syringe needles, reamers, and files, during oral treatment, and in oral surgery outpatient service. The results of multiple linear regression models showed that lack of protection knowledge, no pre-job training, unskilled, being nervous, or absent-minded during working process showed an elevated possibility to be involved to sharp injury（β were 1.02, 0.77, 0.56, 0.31, and 0.74, respectively, all P 〈0.05）. Conclusion] A high incidence of sharp injury is found among stomatological interns. It is recommended to establish a sound occupational protection education system for stomatological students to minimize the occurrence of sharp injuries.
