口腔修复科交叉感染危险因素分析及预防

摘要

Objective To study the risk factors and prevention of cross infection in prosthodontics department. Methods The clinical data of 100 cases admitted and treated in the department of prosthodontics from April 2014 to 2016 were retro-spectively analyzed, and all patients were detected by hepatitis B virus, and the risk factors during treatment of the infection group and non-infection group were compared and analyzed, such as air quality, disinfection and sterilization of the appa-ratus, waste disposal and susceptible population. Results The survey showed that 40 cases were positive HBsAg patients, and the positive rate was 40.00%, in treatment of the non-infection group, the average number of air bacteria in consulting room was (2.45±0.32) cfu/m3, the bacteria number on the apparatus surface was (65.43±7.56) cfu/m2, in treatment of the in-fection group, the average number of air bacteria in consulting room and bacteria number on the apparatus surface were re-spectively (4.54±0.54) cfu/m3 and (125.32±11.67) cfu/m2. The waste disposal in the infection group was more obvious than that in the non-infection group in the diagnosis and treatment, and the differences were obvious between the two groups with statistical significance, P<0.05. Conclusion From the above we can know, the air quality, disinfection and sterilization of the apparatus, waste disposal, susceptible population have a close correlation with the cross infection in prosthodontics department, therefore, we should conduct operation strictly according to the regulations of technical operation in prosthodon-tics department and enhance the disinfection and sterilization of relevant apparatuses used in the department of stomatology, only in this way can the incidence rate of cross infection in prosthodontics department be effectively reduced.%目的：探讨口腔修复科交叉感染危险因素及预防。方法回顾分析该院2014年4月—2016年口腔修复科收治的100例患者临床资料,并对所有患者进行乙型肝炎病毒的检测,对比分析乙型肝炎病毒感染者(感染组)与未感染者(未感染组)之间治疗的过程中出现的危险因素,例如：空气质量、器械的消毒和灭菌、废物处理、易感人群等方面的情况。结果通过调查显示,患者中有40例为HBsAg阳性患者,阳性率占(40.00%),其中未感染组患者的治疗中,诊室的空气细菌平均数量是(2.45±0.32)cfu/m3,器械表面的细菌数量(65.43±7.56)cfu/m2；感染组患者的治疗中,诊室的空气细菌平均数量是(4.54±0.54)cfu/m3,器械表面的细菌数量(125.32±11.67)cfu/m2；诊疗中未感染组的废物处理明显要比感染组显著,两组之间的差异有统计学意义(P<0.05)。结论由上可知,在诊疗中,空气质量、器械的消毒和灭菌、废物处理、易感人群等与口腔修复科交叉感染具有密切的关系,因此,操作中应严格按照口腔修复科技术操作的规程进行,加强对口腔科用到的相关器材进行消毒与灭菌,只有这样才能有效减少口腔修复科交叉感染的发生率。
